    Equity Gilt Study 2009

    54th Edition

    The Equity Gilt Study has been published continuously since 1956, providing data,

    analysis and commentary on long-term returns from financial assets in the UK and US.

    Our UK database begins in 1899, while the US database starts in 1925. The US data are

    kindly provided by the Centre for Research in Security Prices at the University of

    Chicago Graduate School of Business. Our purpose in publishing this data is to provide

    investors with a perspective on long-term asset returns. In the 2009 Study, we examine

    the causes of the very poor equity returns of the past decade, we discuss asset returns

    under varying classes of inflationary and deflationary conditions and we analyse the

    permutations and causes of the credit cycle. Our colleagues at Barclays Global Investors

    contribute a chapter highlighting the advantages offered by ETFs and examining how

    they can be used in a variety of strategies. As always, we also provide a thoroughanalysis of historical returns from a wide variety of asset classes in both the UK and US,

    together with the relevant data.

    We hope you enjoy the essays and find the data useful.

    Chapter 1 The lost decade

    Equity investors have been on a wild and ultimately disappointing ride over the past

    decade. Equities have been the worst-performing asset class since 1997, sharply

    underperforming all other asset classes. We examine the causes of this relative

    weakness, and find that the utility of simple valuation measures has been thoroughly

    vindicated by the dreadful recent returns from equities. We show how future long-termreturns from equities the equity risk premium can be forecast. We also describe the

    factors that cause equity valuations to fluctuate over time. Finally, we compare the

    outlook for stock and bond returns over the next 10 years.

    Chapter 2 Deflated markets

    The financial turbulence of 2008 has led to a fascination with the Depression era.

    Concerns over deflation have replaced the inflation scare which prevailed in the first

    half of 2008. This raises the question over which state presents the greater evil,

    deflation or high inflation? In this article, we compare the performance of a range ofassets and equity sectors across different inflation regimes since the 1920s. We

    differentiate between phases of good and bad deflation to gain further insight and find

    that, in fact, credit conditions may be a more important factor to consider in

    determining trends in asset performance. Perhaps the focus on deflation or stagflation

    has been a diversion in comparison to the importance of credit regimes.

    Chapter 3 Viral economics

    Both the occurrence and the economic impact of the credit crunch caught policy-

    makers, regulators, bankers, analysts and investors largely unprepared. We examinewhy this might be so, given the empirical evidence that credit cycles are inherently

    predictable and of considerable importance to the path of economic growth. Our

    conclusions highlight the endemic instability of a pure free market system.

    Chapter 4 Back to beta with ETFs

    In 1975 Charles Ellis highlighted the shortfall of active managers in his often referenced

    article The Losers Game published in the Financial Analysts Journal, July/August 1975.

    He reported that over the prior decade 85% of all institutional investors who tried to beat

    the stock market underperformed the S&P 500 index. In 1976, the first indexed fund was

    launched in the US. Since then ETFs have become popular and widely used investment

    vehicles. This article discusses the many advantages offered by ETFs and examines how

    they can be used in a variety of portfolio strategies.

    Chapter 5 and 6

    We publish last years US and UK asset Returns, placing them within a historical context.

    Equities had a terrible year globally. The FTSE All-share real total returns were the

    weakest since the 1970s. The US equity returns were the weakest since the Great

    Depression. Government bonds were the main beneficiary of the financial turbulence of

    2008. In both the UK and the US, government bonds were the best-performing asset of

    the year. They also produced the best average annual returns over 20 years. Bonds

    rarely outperform equities over such a long holding period.

    Chapter 1 The lost decadeTim Bond

    Equity investors have been on a wild and ultimately disappointing ride over the past

    decade. Equities have been the worst performing asset class since 1997, sharply

    underperforming all other asset classes. We examine the causes of this relative weakness,and find that the utility of simple valuation measures has been thoroughly vindicated by

    the dreadful recent returns from equities. We show how future long-term returns from

    equities the equity risk premium can be forecast. We also describe the factors that

    cause equity valuations to fluctuate over time. Finally, we compare the outlook for stock

    and bond returns over the next 10 years.

    Equity returns over the past decade have been among the worst on record. In nominal

    terms, the -0.3% annualised return from US equities since 1998 is the fourth-worst 10-

    year return of the past 83 years. Only those 10-year periods ending in 1937, 1938 and

    1939 have delivered lower returns. Similarly, over the past 109 years, only the decade

    ending in 1974 saw a weaker 10-year nominal return from UK equities. For the sake of

    record, the 1964-74 UK equity return was 1.02%, while the 1998-2008 return was

    1.05%. In both the US and UK, the real total return from equities over the past decade

    has been negative.

    As a natural reaction to this long phase of poor returns, there has been much talk of the

    death of the equity cult. While such talk may accurately represent investors

    disenchantment with equities as an asset class, it is most likely a poor forecast for

    future equity returns. Prospective returns from equities are at the most attractive levels

    seen for some 20 years in the US and over 25 years in Europe and the UK, even if ex-

    post returns have been feeble.

    The weak returns from equities over the past decade are not due to some intrinsic

    problem with the asset class. Rather, they are attributable to the extreme overvaluation

    of equities at the start of the decade. Although the growth in corporate profits has been

    robust over the period in question, investors were paying a very high premium to

    access these profits at the start of the decade. This premium has hampered, not to say

    eradicated, positive returns. From 1997 through to 2002, equities were valued at

    unusually expensive levels relative to earnings and corporate net worth. The collapse inequities after 2001 partially corrected this overvaluation, as equity prices declined by

    more than earnings during the 2001-03 global slowdown. The subsequent economic

    boom from 2003-08 generated a strong trend in profitability and in turn generated a

    strong rally in stock markets. However, throughout this period, valuations declined and

    equity prices generally underperformed profits. When the surge in growth ended

    abruptly in 2008, equity prices fell in line with the actual and expected decline in

    profits. Expensive valuations therefore caused equity returns to underperform profits

    following the 2001 slowdown and then did the same during the ensuing boom, while

    finally failing to provide a cushion when the business cycle turned down. Over theentire period, equities behaved like an expensive and eternally out-of-the-money call

    option on corporate earnings.

    Put bluntly, the past decade has provided investors with an object lesson on the critical

    importance of long-term valuation metrics. In Figure 2 we display a history of the two

    most important of these measures for equities. The right hand panel presents the

    history of Tobins Q the market value of equity/corporate net worth. The series was

    constructed using data generated by Stephen Wright of the School of Economics at

    Birkbeck College. The left hand panel displays a trailing real PE ratio, using a 10-year

    moving average of earnings, drawn from data compiled originally by Robert Shiller.

    The charts should serve to illustrate the extraordinary overvaluation of equity markets in

    the second half of the 1990s. From the end of 1996 onwards, the US was consistently

    valued at well over 1 standard deviation expensive to the long run average of both these

    yardsticks. The overvaluation was the most extreme of the past century and indeed of

    recorded stock market history. Perhaps unsurprisingly, subsequent returns from buyingequities at such prices were poor, despite the 2003-08 period recording the strongest and

    most synchronised phase of global economic growth since the 1960s.

    In essence, investors were paying too much to access corporate earnings and corporate

    assets during the stock market bubble years. S&P 500 operating earnings per share rose

    more than 50% between the end of 1998 and the end of 2008. European profits rose by

    considerably more. Had equity prices kept pace with earnings, we estimate that the

    annualised US equity real return would have been in the region of 3-4%, not minus 2.7%.

    A 3-4% real return is certainly well below the 6.4% long run average for US equities and it

    would have been below the 5.7% real return from government bonds, but at least it

    would have beaten cash, which delivered an annual real 0.7% over the period in question.

    As it was, equities were the single worst-performing asset class during the 1998-2008

    decade for the sole reason that they were the most overvalued asset class at the start of

    that period.

    The rather brutal lesson we can glean from the past 10 years is that valuations, rather

    than macroeconomic conditions, and the progress of corporate profits, are the core

    determinant of equity market returns. The investment industry as a whole devotes

    enormous resources to the analysis of each quarters corporate profits and considerable

    effort is expended on forecasting the economic cycle. Yet very little attention is paid to

    aggregate valuation. Unfortunately, this balance of attention is flawed. Over the long

    run, equity valuations appear to be the primary driver of equity returns, with economicconditions and profit trends contributing little, if anything, to the overall total return

    from an investment in equities. Profits and growth explain the more minor fluctuations

    of equity prices from quarter to quarter and year to year, but they are incapable of

    explaining multi-year returns. Admittedly the converse also applies, in the sense that

    valuations tend not to be able to explain shorter-run fluctuations in the stock market.

    At time scales of much under five years, valuation becomes less relevant, with the

    economic and profit cycle becoming the key explanatory variables. However, since

    equities are typically held for the long run and are predominately owned by institutions

    or individuals with long liability structures, it would seem reasonable to suggest that

    more attention should be paid to the predictive capability of valuations. In short, if the

    equity premium is forecastable, it makes sense for us to avail ourselves of the forecast.

    To illustrate this point, consider the two valuation metrics mentioned earlier Tobins

    Q ratio and Shillers PE ratio based on 10-year real earnings. Both these metrics have a

    solid empirical record of successfully forecasting equity returns. In Figure 3 we illustrate

    this relationship. The charts compare rolling 10-year annualised nominal returns from

    US equities to the Q ratio and to the real PE ratio at the start of each of the 10-year

    periods. The returns are plotted annually and the sample period begins in 1925. The

    charts demonstrate the strong negative correlation between these two valuation

    metrics and subsequent returns, showing how expensive valuations are associated with

    low returns and vice versa.

    The relationships are sufficiently robust to allow the possibility of forecasting. Figure 4

    illustrates the results of a regression exercise, where the Q ratio and the real PE ratio

    are used independently to forecast 10-year equity returns. Both variables produce very

    similar forecasts. In Figure 5 we combine both metrics in a single model and also

    perform an out-of-sample test on the methodology, stopping the regression in 1990 to

    allow the model to forecast thereafter. This test shows both that the relationships are

    reasonably stable over time, and that the model was effective in forecasting the general

    trend in equity returns after 1990. In particular, the model correctly forecast that equity

    returns would be negative over the past 10 years. The model failed to predict the 1997-

    2002 stock market bubble and therefore under-estimated returns in the periods ending

    in those years. However, any gains that an investor could have made from riding the

    bubble would have been temporary and reliant on an exceptional and perhaps

    improbable ability to time the market.

    Currently, the model suggests that a purchase of US equities at the close of 2008 will

    deliver a nominal annualised return of between 12.4% and 13.4% over the next 10

    years. This forecast is corroborated by a similar exercise with another long-standing

    valuation yardstick, the price/dividend ratio. We find this metric less efficient in

    forecasting equity returns, but nonetheless it produces statistically significant results, as

    illustrated in Figure 6. The price/dividend ratio, which was similarly over-valued at the

    1998-2001 peak, suggests the future 10-year return (end-2008 to 2018) will be an

    annualised 11.2%. Averaging these various results produces a forecast for the future

    10-year nominal equity risk premium of 12.3%.

    If the methodologies described above accurately forecast the past decade of poor

    equity returns, the question arises as to why these signals were broadly ignored byinvestors. It was certainly not due to a lack of information. By way of illustration, Robert

    Shillers book Irrational Exuberance, which espoused the 10-year real PE ratio as a core

    yardstick for prospective equity returns, was published in 2000. Similarly, work by

    independent analysts such as Andrew Smithers highlighted the relative expense of

    equities signalled by Tobins Q ratio as early as 1998. If the warning signals were

    available, they were not generally acknowledged by market participants. To be sure, the

    equity bubble of 1997-2001 was widely seen as such. At the time, proponents of a New

    Era in valuations were at least partly counterbalanced by a vociferous minority, who

    accurately defined the trend as an unsustainable boom. However, from 2004 onwards,

    the strong growth in profits generated by a buoyant global economy tended to obscure

    the point that equity returns were continuing to be dampened by a persistent trendtowards lower valuations. Coincident returns were certainly strong, partially reflecting

    the strength in profits; however, once profits turned down, equity prices fell back in

    lock-step with the drop in earnings. Stock markets therefore underperformed earnings

    during the expansion, but performed in line with earnings during the contraction. At

    the start of 2009, equity prices are slightly lower than they were at the end of 1998,

    even though prospective profits for the impending year are likely to be considerably

    higher than they were in 1998, a deep global recession notwithstanding.

    The fluctuation in equity valuations over the past decade demands a closer

    consideration. While it is easy in retrospect to ascribe weak returns to overvaluation,

    such an explanation does not tell us why the overvaluation occurred in the first place.To write the decade off as an epic example of the madness of crowds would seem to be

    too glib an analysis. Indeed, our own research has led us to the conclusion that simple

    irrationality may have played a much smaller role in moulding recent stock market

    returns than is popularly imagined. Rather, it seems that investors and the markets

    were in the grip of powerful forces that were hard for any individual to withstand. We

    can identify two particular and perhaps related fundamental trends at work.

    First, it is reasonable to suppose that the original decline in the forward-looking equity

    risk premium reflected the broad decline in macroeconomic volatility that occurred from

    the mid-1980s onwards. As the peaks and troughs of the business cycle grew less

    pronounced during the period generally termed the Great Moderation, so the volatility

    of profits and the intrinsic riskiness of corporate liabilities also declined. The fall in ex-ante

    equity risk premia, personified by the rise in PE ratios and the rise in equity market

    capitalisation relative to corporate net worth, can therefore be seen as a straightforward

    11/95

    10 Global Asset Allocation Strategy Barclays Capital

    extrapolation of prevailing conditions on the part of investors. As the collective memory

    of the 1970s faded, so the extrapolative process became more firmly embedded in market

    psychology. The limited macroeconomic volatility of the 1980s and 1990s came to be

    seen as the norm, while the 1970s were held to be an aberration attributable to poor

    economic structures such as over-mighty trade unions and poor economic

    management such as excessively lax monetary policy. On the basis that these mistakes

    were recognised and therefore unlikely to be repeated, market participantsunderstandably expected the decline in macroeconomic volatility to persist.

    We believe that much of the move higher in equity valuations and indeed the

    accompanying accumulation of leverage in the household, financial and corporate

    sectors can be explained, if not justified, on this basis. Unfortunately, the extrapolative

    process generated its own downfall. The increase in equity valuations simultaneously

    increased the probability of poor future returns. In the same vein, the increase in

    general leverage on the basis of low macroeconomic volatility raised the sensitivity of

    the economic and financial systems to small changes in fundamentals. By 2007, a very

    modest tightening of monetary policy by the standards of past business cycles was

    sufficient to trigger a collapse in the over-extended US housing market, thereby

    tripping the global economy into the worst recession of the past 50, if not 70, years. In

    essence, the Great Moderation was inherently unstable and prone to self-dissolution

    because people recognised its existence and adjusted their behaviour accordingly. The

    eventual denoument was as sure and inevitable as the plot of any dramatic tragedy.

    Indeed, since the process was generated by the actions of human beings, it is perhaps

    unsurprising to find that the terms of analysis of tragic literature hubris, harmatia,

    pathos and (it is to be hoped) catharsis can translate so easily into the economic field.

    To frame the discussion in somewhat more quantitative terms, we can illustrate the

    connection between equity valuation and economic volatility. A popular standard

    explanation for shifts in equity valuation highlights the empirical inverse correlation

    between PE ratios and inflation. While this explanation is observationally correct, it is

    intellectually unsatisfying. This is because it fails to explain why the valuation attached

    to an asset that correlates positively to inflation the stream of corporate earnings

    should exhibit a negative correlation in practice. If we instead regard the link between

    PE ratios and inflation as symptomatic of a deeper correlation between inflation and

    economic volatility, the pieces of the jigsaw fall into place. An accelerating inflation rate

    is an inherently unstable process because it is exponentially self-feeding. A persistent

    rise in inflation therefore raises current and prospective macroeconomic volatility.

    Under such conditions, the desire for a higher ex-ante equity risk premium is logical. As

    rising inflation raises the riskiness of the economic cycle, so investors demand a greater

    risk premium to compensate for an increase in the dispersion of future outcomes. In

    Figure 7 we illustrate this effect at work. The graph compares a moving average of the

    quarterly volatility of both real GDP growth and inflation to the US trailing earnings

    yield. Self-evidently, an increase in this measure of volatility generates an increase in

    the earnings yield and vice versa.

    The decline in equity earnings yields during the 1990s can therefore, be seen as a reactionon the part of investors to the decline in macroeconomic volatility. The more recent rise

    in earnings yields is similarly reflective of an increase in the volatility of both inflation and

    growth during the current business cycle. The relationship between coincident economic

    volatility and financial asset risk premiums is a simple reflection of the extrapolative

    process by which we create a model of the future based on the recent past. Such

    mechanisms served us well when avoiding the multiple external threats of the African

    savannah. They are perhaps less useful when our own worst enemy is ourselves.

    There is, however, an additional and perhaps more inexorable explanation for

    fluctuations in equity valuations. In past editions of the Equity Gilt Study we have

    highlighted the link between trends in financial asset yields and trends in demographics.

    In particular, fluctuations in the population cohorts of savers and the retired correlate

    strongly with bond yields and earnings yields. Thus when we observe the long run

    rhythm of financial asset yields, the ratio of the 35-55 year old population to the total

    population correlates negatively, while the growth rate of the newly retired population,

    which we define as 65-75 year olds, correlates positively. Indeed regression models in

    which the sole variables are these demographic components appear to explain long

    trends in stock and bond yields quite well. The same variables also explain changes in

    the Q ratio over time. Figure 8 and Figure 9 illustrate these points.

    Unusually, the relationship between demographics and bond and stock yields conforms

    to both common sense and economic theory. A population in which the high savingsage cohort is dominant will be characterised by a strong demand for financial assets.

    This demand will be reflected in higher-than-otherwise financial asset prices and lower-

    than-otherwise yields. Conversely, since the retired will typically be sellers of financial

    assets, a society in which the retired population is large or growing rapidly is likely to be

    characterised by a weaker demand for financial assets and hence higher-than-otherwise

    yields. The demonstrable correlation of financial asset yields with demographic trends

    supports the notion of the Lifecycle Theory of Savings writ large across the economy.

    Speculatively, we might add the following rider. Bearing in mind the clear connection

    between inflation and financial asset yields, it is possible to infer a relationship between

    demographics and macroeconomic volatility. Certainly there is some logic to a link

    between the worker-dependent ratio and the propensity for inflation. After all, if

    globalisation is held to have been a restraining force on inflation over the past 20 years

    due to the expansion of the global labour force, it is reasonable to propose a similar

    effect from a natural expansion of a workforce due to demographic trends. Without

    wishing to belabour this point, we can surmise that growth in the baby-boomer

    working age population over the past three decades may well have been one of the

    factors keeping inflation in check. Similarly, as the baby-boom generation ages into

    retirement over the next decade, it is plausible to believe that the wage bargaining

    power of the remaining labour force will rise and that inflationary shocks might carry a

    greater risk of persistence.

    As far as financial assets are concerned, the growing demographic dominance of thehigh savings age cohort helps explain the rise in equity valuations during the 1990s. As

    the boomer generation entered their peak savings years, the competition for financial

    assets drove prices ever higher. It is particularly noteworthy that the US equity bubble

    peaked in the same year that the US high savers cohort peaked as a ratio to the general

    population. A similar timing was visible in early 1990s Japan. Meanwhile the subsequent

    move lower in valuations can be explained both by the pick-up in the growth of retirees

    and the decrease in the high savers-total population ratio.

    For bond markets, demographic models expected a phase of very low nominal yields

    from the late 1990s onwards, but are now beginning to point towards a reversion to

    higher yields. Roughly, the demographic models expected bond yields to trough arounda decade after equity yields. Such a time lag makes sense, since the demand for equities

    would be hit first by a fall in the ratio of high savers to the general population, whereas

    the demand for bonds would be sustained or even buoyed as retirees shift into

    income-bearing assets. At a later point, the social security fiscal strains of an ageing

    population, along with the impact of a shrinking workforce on inflation and tax

    receipts, might be expected to be factors pushing bond yields higher. Looking forward,

    demographic trends would seem to point to an era of low equity valuations,

    accompanied by rising bond yields.

    The apparent end of the Great Moderation in economic volatility conveys a similar

    message, as the world struggles to adapt to the emergence of giant developing

    economies. As Figure 10 and Figure 11 should hopefully illustrate, the relationship

    between global growth and raw material inflation shifted unfavourably during the

    current cycle. The primary cause was a severe demand shock, driven by the growing per

    capita resource appetites of the large developing economies and the greater raw

    material intensity of growth in industrialising economies. It was also clearly the case

    that a constrained response from the supply side failed to accommodate the leap in

    commodity demand. The weakness in the supply response is attributable to multiple

    causes, ranging from endemic scarcity, through environmental considerations, to

    under-investment. Our analysis of this topic is available in the past two years editions

    of the Equity Gilt Study. Please see Chapter 1 of theEquity Gilt Study 2008and Chapter

    In the most recent business cycle, the net boost to global inflation, prompted by the

    increased resource intensity of global growth, was sufficient to raise interest rates to

    levels that catalysed the asset price deflation and de-leveraging trends that are visible at

    present. An economic system whose levels of leverage and asset prices were predicated

    on endlessly low inflation proved to be unsustainable at the first whiff of higher inflation.

    In the short term, it is reasonable to believe that the de-leveraging of the private sectors

    in a number of over-extended economies will keep global demand and hence inflation

    weak. Over the longer run, it is difficult to evade the impression that this effect will fade

    and that the problem of accommodating the resource appetites of the developing world

    will re-emerge. As a consequence, the balance of probability seems tilted towards the

    persistence of high in comparison to the last three decades macroeconomic volatility.

    Overall, both demographic and economic factors suggest that equity valuations may

    fall a little further and remain low for a while, before recovering later in the decade.

    Both factors also suggest that bond yields are likely to trend higher at the same time.

    However, of the two asset classes, we expect that equities are likely to reverse their long

    phase of underperformance against bonds. As far as bonds are concerned, rising yields

    will self-evidently damage returns. In contrast, as we have seen, lowly equity valuations

    tend to confer higher-than-average future long-run returns. This is both because a

    performance-damaging decline in valuations becomes less likely and because aneventual performance-enhancing rise in valuations becomes more likely, at low levels of

    valuation. Or, to put it rather more simply, equities are likely to outperform bonds over

    the next decade because equity yields are already high, whereas government bond

    yields have yet to rise. To summarise, we are in an environment in which forward-

    looking measures of equity risk premia should be high, compensating for a more risky

    macroeconomic environment and a reversal of the demographic forces that have

    supported asset prices in the recent past. If history is any guide, such a period should

    present long-term investors with an opportunity to gain cheap access to corporate

    profits and net worth.

    Chapter 2 Deflated marketsSreekala Kochugovindan

    Financial markets have endured one of the most turbulent episodes in history. At the time

    of writing, the peak to trough fall in the S&P500 since the start of the credit crunch stands

    at 52%. A collapse of that magnitude surpasses the bursting of the dotcom bubble, (adrop of -49%), the crash of 1987 (-33.7%) and the OPEC crisis of 1973 (-48%). We have

    to go as far back as the 1930s to find a more acute equity sell off. Unsurprisingly, a

    fascination with the depression era has developed and concerns over deflation have

    replaced the inflation scare which prevailed in the first half of 2008. This raises the

    question over which state presents the greater evil, deflation or high inflation? In this

    article, we compare the performance of a range of assets and equity sectors across

    different inflation regimes since the 1920s. We find that over the past six years, the

    distribution of equity returns have switched from emulating one extreme episode of

    history to another, from stagflation to deflation, in under a decade. We differentiate

    between phases of good and bad deflation to gain further insight and find that, in fact,

    credit conditions may be a precondition for bad deflation and, in turn, a more importantfactor to consider in determining trends in equities. Perhaps the focus on deflation or

    stagflation has been a diversion in comparison to the importance of credit regimes.

    Inflation extremes

    We begin by examining the average real returns of US equities, bonds and cash during

    the three inflation phases since 1929. High inflation is classified as inflation greater than

    the long run average of 4%, the stable years include inflation between 0% and 4% and,

    finally, deflation where the annual inflation rate is negative.

    Historically, the US stock market has produced the best returns during periods of low and

    stable inflation with an average real return of 11%. Although equities are considered to

    provide a hedge against inflation in the long run, the short-term performance can be

    quite poor. Equities can be susceptible to sharp declines in the face of unexpected

    inflation spikes. For example, US equities slumped over 50% during 1973 and 1974 before

    rallying 30% the following year. Figure 12 shows that equities produced a small positive

    average real return during the high inflation years; however, examining the sector level

    data over these years, we find that these returns are skewed toward the commodity-

    related companies. The mining sector produced the best average returns of 6% pa.

    During the deflationary years stocks provided the worst performance, with dire returns

    across all the sectors. Instead, returns are concentrated in bonds and cash as both

    traditionally perform well during periods of risk aversion. Credit spreads, on the other

    hand, widen quite dramatically during deflationary episodes. The table below highlights

    the annual change in the spread between long-run investment grade credit and 30-year

    Treasuries. The deflationary years show an average spread change of 100bps since 1929.

    This is in sharp contrast to the other two inflation regimes. During the low and stable

    inflation years, spreads barely move with an average spread change of half a basis point.

    The high inflation periods suggest that credit spreads only widen on average by 8bps.

    Thus, in extreme inflation conditions, whether it happens to be deflation or high

    inflation, portfolio diversification does not seem to be the best approach given that

    returns are so heavily concentrated in either resource-based stocks in the case ofinflation, or government bonds in the case of deflation.

    To put the more recent experience in context, we compare sector behaviour during the

    past five years with the sector behaviour during the deflationary episode in the 1930s

    and the stagflationary 1970s. We separate the equity returns over the past six years

    into two phases: 2003 to July 2007 to capture the period of global growth and booming

    equity and commodity markets, which originally led to the inflation scare, and the

    second phase covering the credit crisis. The charts highlight a remarkable similarity

    between the sector returns of the 1970s and between 2003 and 2007. In both cases, the

    commodity-driven inflation spike led to portfolio returns being highly concentrated in

    commodity-related equity sectors. There also appears to be some similarity between

    sector returns during the great depression and the credit crunch. Financials were the

    worst performing in both cases. Although we do not believe that the current crisis will

    follow the path of the Great Depression the substantial global fiscal and monetary

    stimulus currently employed is likely to prevent such a scenario it is, however, very

    interesting to note that over the past decade, equity returns have switched fromemulating one extreme episode of history to the exact opposite extreme.

    Dissecting deflation

    The three inflation categories described in Figure 12 could be considered too simplistic.

    Bordo and Filardo (2005)1 distinguish between good and bad deflation. They examine a

    number of examples dating back to 1800 in order to identify the main features and

    determinants of each phase of deflation. Historically, good deflation tends to be a

    characterised by a mild decline in the price level accompanied by economic growth.

    One example given by Bordo et al is the 1921-29 period where many countries

    experienced robust growth as a result of the post-war recovery process, the growth of

    consumerism and new high-tech industries, such as cars and radios. The bad deflation

    promptly followed during 1929-33. Sharp price declines were accompanied by

    dramatic falls in real output across many countries. In the US inflation fell over 20%

    during those three years while real output fell by 7.6%.2

    The chart below plots the performance of equity sectors during the good and the bad

    deflationary episodes and highlights how the simple classification of deflation in Figure

    12 masks some dramatic differences in the distribution of returns. Between January

    1926 and August 1929, US CPI declined by a cumulative 3.4%. At the same time USequity sectors rallied between 70% (Retail sector) and 164% (Manufacturing). During

    the bad deflation years CPI fell by a cumulative 30% while equities fell between 66%

    (Manufacturing) and 90% (services).

    The volatility of returns during the phases of deflation also differs quite dramatically.

    Figure 15 plots the volatility of daily sector returns during the good and bad deflation

    episodes alongside the stagflationary decade of the 1970s. The 1929-33 bad deflation

    period shows that returns are consistently more volatile than in either of the other two

    phases. During 1929-33 bad deflation period, volatility nearly doubled for the best-

    performing sectors of the 1926-29 period, manufacturing and transport. These same

    sectors were 2.5x and 3.5x more volatile during the 1930s than in the stagflationary

    1970s. Part of this difference may be due to the fact that economic volatility was so

    much greater during the 1930s. The rolling 10-year standard deviation of annual GDP

    growth was in the region of 9% in 1939, by the 1970s the volatility of growth had fallen

    This leads us to reassess the definition of good and bad deflation as outlined above, which

    was primarily dependent upon the economic growth rate. A number of the episodes of

    good deflation outlined in Bordo and Filardo (2005) were followed by a shock that led to

    a banking crisis which in turn, was followed by a phase of bad deflation. Figure 16 returns

    to phase of good and bad deflation and compares equity returns against the long run

    credit spread as well as industrial production growth. Although the US experienced strong

    economic growth during the good deflation period, annual industrial production growthreached over 40% in 1922, the economic environment was turbulent throughout the

    decade, with a short bout of negative growth in 1924. Regardless of these fluctuations in

    growth, equities continued to rally against the backdrop of tight and stable credit spreads.

    The bad deflation phase was accompanied by a dramatic widening in credit spreads as

    well as a decline in growth. The 1933 recovery only began when spreads began to tighten

    back to more stable levels.

    A similar analysis for the 1970s shows that equity returns were again very closely

    correlated with credit spreads. In 1974, spreads contracted and equities rallied six

    months before industrial production had troughed, so it was not necessary for growth

    to get underway for equity and credit markets to stage a recovery. The chart also

    suggests that equities recovered one month before the credit market. There is no clear

    statistical evidence to suggest whether equities lead or lag the credit market, although

    there is some evidence to suggest that credit spreads may be a causal factor of extreme

    inflation episodes. The granger causality test between equities and inflation on monthly

    data since 1919 to 2008 suggests that statistically causality runs from credit to

    inflation. Bordo and Filardo (2005) test the impact of banking crisis on the probability

    of deflation being good, bad or ugly. They find that if a banking crisis occurs, theprobability of a good deflation phase taking place, drops considerably, while the

    probability of bad deflation rises. This suggests that a financial shock which leads to

    tightening credit conditions and a dramatic widening in spreads maybe more important

    in driving the volatility of inflation and in turn the volatility in financial assets. Perhaps

    the focus on deflation or stagflationary regimes is a diversion in comparison to the

    importance of credit regimes.

    The credit impact

    To ascertain the potential impact of credit spreads, we examine the average equity return

    during four stages of the credit cycle: 1) low stable spreads; 2) widening credit spreads; 3)

    high and stable spreads; and 4) tightening spreads. Figure 18 illustrates the results, the

    chart on the left plots the average quarterly equity returns since 1919, the chart on the

    right adds in the maximum and the minimum return achieved during each phase.

    Barclays Capital Global Asset Allocation Strategy 21

    On average, periods of low and stable credit spreads produce small yet positive returns,

    with a relatively low dispersion, a range of +/-20% per quarter. Unsurprisingly, the worst

    returns are posted during the spread-widening phase. The average return falls to -6%,

    with a significant increase in the maximum downside to -40%. Wide and stable spreads,

    our most likely scenario for the coming months, has a disappointing average return of

    -4% per quarter; however, this regime has had greater upside potential than either low

    and stable or rising spread regimes. The maximum historical return during this phasehas been 35%, with a maximum downside of -30%. The best returns occur during the

    tightening phase, with an average quarterly return of 4.3%, and a maximum return as

    high as 86%, which occurred during the sharp credit-tightening phase of the 1930s.

    It seems that the similarities drawn between the current distribution and volatility of

    equity returns with that of the 1930s are driven more by the credit cycle than any real

    danger of a rerun of the Great Depression. Our analysis here suggests that allocating

    with deflation in mind may be the wrong approach. A clearer understanding of the

    credit cycle could be far more important in better understanding future trends in

    financial assets.

    Chapter 3 Viral economicsTim Bond

    Both the occurrence and the economic impact of the credit crunch caught policymakers,

    regulators, bankers, analysts and investors largely unprepared. We examine why this

    might be so, given the empirical evidence that credit cycles are inherently predictableand of considerable importance to the path of economic growth. Our conclusions

    highlight the endemic instability of a pure market system.

    The events of the past two years have served to underline the importance of the credit

    cycle as an independent economic determinant. Too many traditional economic models

    have tended to regard the credit cycle as identical to the interest rate cycle. Changes in

    official interest rates occupy a core position in the formulation of economic forecasts,

    whereas fluctuations in the price and availability of private credit attract less attention.

    The comparatively minor importance attached to credit measures in economic

    forecasting is hard to fathom. On some grounds, credit variables are better at

    forecasting economic growth than are official interest rates. In particular, quantitative

    measures of credit availability, such as that provided by the Federal Reserves Senior

    Loan Officer Survey (SLO), appear to correlate more strongly with subsequent nominal

    economic growth rates than do measures of official monetary policy settings. This

    survey, which is unfortunately only available as a continuous series from 1990 onwards,

    asks bankers a series of standardised questions about their lending habits on a quarterly

    basis. The results are then reported in the form a diffusion index. Over the course of the

    past 18 years, the Survey has provided an extremely accurate leading indicator for

    major fluctuations in the US business cycle.

    Figure 19 illustrates this point, comparing the Surveys questionnaire about whether

    terms and conditions for Commercial and Industrial Loans are tightening or easing, with

    the pace of nominal GDP growth. The highest correlation of -72% is achieved with theSLO survey leading growth by half a year. In Figure 20, we repeat the exercise for the real

    Fed Funds rate, where the optimal correlation of -48% was achieved with the Funds rate

    leading growth by two years. Fairly clearly, the Loan Officer Survey is a more effective

    leading guide for the business cycle than the Fed Funds rate. We subjected the Loan

    Officer survey to a Grainger causality test, to check that the correlation was not merely

    picking up the pro-cyclical nature of bank lending. The test confirmed that the changes in

    lending conditions did indeed stimulate changes in nominal economic activity.

    Despite the empirical evidence, until very recently, credit variables have rarely been

    allotted much weighting in economic forecasting models. The relatively greater

    forecasting importance allotted to monetary policy settings rests on a belief that that

    changes in actual and expected official interest rates are the primary determinant of

    interest rates elsewhere in the economy. Yields for private sector credit are therefore

    assumed to move in line with the interest rates controlled by monetary authorities.

    On average, such a presumption is correct. For the sake of example, over the past 50 years,

    long-dated US corporate bond yields display a correlation of 76% to short-dated

    government bond yields. However, the average of any relationship can conceal plenty of

    examples of very non-average behaviour. Figure 21 illustrates this point. The chart shows

    the rolling 18-month correlation between annual changes in US corporate bond yields and

    short-dated government yields. Typically, the correlation is strongly positive, but there are

    sporadic outliers such as 1974/5 and 2007/8 when the correlation swings sharplynegative. There are also a couple of occasions 1994 and 1998 when the correlation fades

    to zero. Significantly, each of these outliers is associated with a severe financial crisis, during

    which the financial system which acts as an intermediary between the central bank and

    the economy was subject to great stress. In 1974/5 and 2007/8 these financial crises

    caused or exacerbated very deep recessions. In 1994 and 1998 the crises were more or less

    confined to the financial markets government bonds in 1994 and credit in 1998.

    The importance of credit variables during these outlier phases can be illustrated by

    the current downturn. In Figure 22, we compare the actual path of US nominal GDP

    growth during the current crisis, with those paths projected by regressions derived

    from the SLO measure of credit conditions and the real Fed Funds rate. The forecast

    generated by the lagged Fed Funds measure envisaged a gentle deceleration in

    growth of a little over 1%, with no real risk of recession. The forecast generated by

    the SLO survey, of a 4% deceleration, was much closer to the actual outcome,providing a solid warning of recession.

    Since the credit cycle follows its own path that is occasionally distinct from that

    projected by official interest rates, it is useful to understand the dynamics that lie

    behind fluctuations in the pricing and availability of credit. Focussing on the availability

    of US bank credit measured by the aforementioned Senior Loan Officer survey, we

    found two key variables that appear to explain the bulk of historic fluctuations in banks

    appetite to lend: past monetary policy settings and the past appetite to borrow. To first

    focus on the impact of monetary policy, we found that the real Fed Funds rate (deflated

    by headline CPI) explained changes in C&I loan conditions with six quarter lag,.. This

    result conforms to a common sense expectation that a tightening or easing of

    monetary policy will eventually encourage or discourage banks in their lending policies.

    The result also conforms to the findings displayed in Figure 19 and Figure 20, whichshowed that the strongest correlation between the real Fed Funds rate and nominal

    GDP growth was found at an eight-quarter lag, whereas the strongest correlation

    between C&I credit conditions and growth was found at a two-quarter lag.

    The second variable that we found to be important was also intuitively obvious.

    Broadly, the non-financial corporate borrowing appetite appears to be a strong

    influence on future credit conditions for corporate borrowers. This is a wholly

    reasonable relationship, as changes in the demand for credit should as in any market

    for any good or service influence the eventual pricing of that item. In this instance, we

    found that a measure of corporate credit demand that also contained a leading

    measure of corporate creditworthiness outperformed simpler gauges, such the ratio ofnon-financial corporate borrowing to GDP.

    To explain our methodology, we should note that the core corporate borrowing

    requirement reflects the financing gap, which is the excess of capital investment over

    internal cash flow, after deducting dividend and tax payments. However, in recent

    years, the non-financial corporate sector has spent considerable sums over $2 trillion

    since the end of 2001 on purchasing equities. Indeed, by the fourth quarter of 2007,

    companies were spending more on equity purchases than on capital investment. A

    significant portion in the variation in the corporate sectors appetite to borrow has atleast in recent history been driven by changes in the sectors appetite to purchase

    equity. The same was true of the previous expansion, from the mid-1990s through to

    the end of the century (see Figure 23). As the right-hand panel of Figure 23 should

    illustrate, during the most recent business cycle expansion, a much larger portion of the

    overall increase in corporate borrowing was attributable to equity purchases than

    capital expenditure. The boom in business borrowing was almost exclusively driven by a

    leveraging of the corporate capital structure by private equity firms and other players.

    The previous two business cycles, therefore, have been characterised by sizeable

    substitutions of corporate debt for corporate equity in the liability structure of the

    sector. The trend has been visible in the surge in M&A volumes, the prevalence of

    leveraged buyouts generated by the private equity business and in the use of share

    buybacks to ostensibly return profits to shareholders. The leveraging of the corporate

    sector has a variety of underlying causes, including an agency problem with

    management incentive structures, pension fund disenchantment with quoted equity

    returns after the 2002-03 bear market, a confusion of the financial results attributable

    to leverage and attributable to better management and last, but not least, sheer bullish

    sentiment on the part of many CEOs. Regardless of the multiplicity of causes, the

    macroeconomic impact is clear. The substitution of debt for equity inevitably weakens

    the creditworthiness of the corporate sector. Despite a popular perception that the

    non-financial corporate sector entered the current recession in good shape, the facts

    of the matter are that the recent boom in debt-equity substitution has left the

    corporate sector in its worst shape from a credit perspective of the entire post-war

    period. As Figure 24 should illustrate, the debt/profit ratio for the US non-financial

    corporate sector rose to 7 during the recent expansion, an all-time high. Thus, at the

    peak of the profit cycle, each 1% change in interest rates on this $7 trillion stock of debt

    moves profits by 7%.

    To return to the main point, debt for equity substitution increases the appetite to

    borrow and decreases the creditworthiness of the borrower. From both perspectives,

    the trend will therefore be of relevance to the banking sectors willingness to lend to

    businesses. As such, the measure of the corporate financing gap that also includes the

    trend in corporate equity net purchases should be effective in explaining changes in C&I

    loan conditions. If we express this measure as a ratio to internal corporate sector cash

    flow, we are presented with a calculation that captures the corporate borrowing

    requirement. The measure also serves as a gauge of creditworthiness, incorporating

    information on the extent of equity retirement and on the changes in borrowing

    relative to the changes in profit growth. This measure is more effective in explaining

    variations in C&I loan conditions than a straightforward financing gap, leading by six

    quarters at an 82% correlation, compared to four quarters at a 67% correlation. The

    measure also outperforms a simple ratio of corporate borrowing to cash flow.

    If the real Funds rate and the aforementioned measure of the corporate borrowing

    requirement are combined as twin variables in a regression model, we have a reasonably

    robust framework for explaining and indeed predicting fluctuations in the credit cycle.

    The model is illustrated in Figure 26, below. The panel on the right displays the history of

    the model in entirety, while the panel on the left displays a snapshot of the models

    predictions as of Q1 of 2007. As this panel demonstrates, the model proved effective in

    forecasting the subsequent general tightening in credit conditions, a signal that allowedthe Barclays Asset Allocation team to turn bearish on the credit asset class early in 2007.

    On a different note, it is worth comparing Figure 25 and Figure 26. It should be clear that

    the model that includes the Fed Funds rate as a variable is currently under forecasting the

    actual tightness of credit conditions. Meanwhile, the financing gap alone is doing a better

    job of prediction. The divergence offers an illustration of the extent to which past excessive

    borrowing and leverage have made bank lending practices irresponsive to monetary

    policy. It should also be noted that both versions of the model suggest that the natural

    peak in tight lending condition is Q1 2009, conditions gradually easing thereafter.

    Hopefully we have demonstrated that fluctuations in the credit cycle are amenable to

    forecasting. If we widen our analysis of the credit cycle to include default rates and

    corporate bond spreads, we can show that they are similarly predictable on the basis of

    some simple econometric models. To be sure, most such models require

    macroeconomic inputs, such as GDP growth, unemployment and so on. However the

    broad point is that credit pricing and credit fundamentals display reasonably reliableand stable responses to changes in underlying economic factors. Thus corporate default

    rates rise after a phase in which corporate borrowing rises faster than corporate profits.

    Rising household leverage, increases in debt-service burdens and increases in

    unemployment will generate increases consumer loan defaults. Similarly, each

    incremental rise in house price income ratios increases the probability of higher

    mortgage defaults. These are logical and intuitive relationships whose existence can be

    proven empirically. If we use these measures in tandem with standard forecasts for the

    main macroeconomic variables, we can then derive a judgement about the

    sustainability of particular trends. The following exhibits illustrate this point.

    Figure 27 portrays a model for net loss rates on US commercial bank loan books. The losses

    are expressed as an annual percentage of total loans. The explanatory variables include the

    tweaked measure of the corporate financing gap described above, as well as corporate

    profits, GDP growth, house prices, changes in unemployment and inflation. Although an

    accurate forecast by the model depends to an extent on accurate macroeconomic forecasts,

    the model underlines the point that bank loan losses display predictable responses to

    changes in economic conditions. In the right-hand panel ofFigure 26 we highlight the point

    that the ratio of corporate borrowing to cash flow tends to lead bank loan losses by a year

    and a half. Thus, even in the absence of any reliable economic forecasts, a reasonably well-

    informed trend direction can be ascertained for bank loan losses.

    In Figure 28 we make a similar point. Here, we display a model designed to predict

    defaults on consumer loans, the default rate expressed as an annual percentage of total

    consumer loans, with key variables including household debt-to-income ratios, debt

    servicing burdens, interest rate changes and unemployment. As with the business-

    related default measures, variables capturing snapshots of household creditworthiness

    tend to lead defaults by up to two years. Trends in defaults and loan losses can

    therefore be ascertained, even in the absence of precise economic forecasting.

    These examples should serve to underline the simple point that cyclical fluctuations in

    most aspects of the credit cycle are far from random. So, in the light of the financial

    cataclysm that has unfolded over the past two years, the question that begs is why did the

    tightening in credit conditions come as such a surprise to lenders, investors, regulators

    Although there were plenty of other causes of the US residential mortgage debacle, a

    primary underlying reason was that participants drastically underestimated the impact

    of falling house prices on mortgage defaults. This was due to the lack of any such

    evidence in the US historical database. As a result, default models tended to

    underestimate the connection between delinquency and house prices, lulling

    participants into a false sense of comfort regarding the impact of any decline in

    residential property prices on residential mortgage creditworthiness.Indeed, the reverse process applied. The extended phase of rising house prices had

    reduced mortgage defaults by allowing potential delinquents the option of positive

    equity extraction. This process in turn began to accumulate evidence that borrowers at

    the lowest end of the creditworthy spectrum were perfectly capable of servicing

    mortgages. As a result, the creditworthiness of lower credit scoring borrowers

    apparently rose. The impact was to encourage lenders to weaken lending standards,

    resulting in the now notorious surge in lending to the sub-prime category of borrower.

    In essence, because the inputs to US mortgage delinquency models were missing a vital

    piece of historical evidence, the models signally and woefully underestimated likely

    defaults. This is a prime exponent of the old computing adage about junk in, junk out.

    Two fundamental failures lie at the heart of the credit crunch; a failure to recognise the

    volatility of house prices and failure to recognise the importance of house prices to

    borrower creditworthiness. In essence, lenders did not pay attention to the potential

    variability in the value of the collateral underpinning their loans. Precisely the same faults

    might be attributed to the surge in lending to the corporate sector, a significant contributor

    with a 38% share since the end of 2002 to the general rise in non-financial indebtedness

    during the current cycle. In this case, lenders may very well have underestimated the

    potential volatility of corporate profits. Certainly, the general acquiescence to higher

    debt/EBITDA ratios and weaker covenanting can only be rationalised on the basis that

    lenders shared the judgement of many policymakers that the business cycle had been

    tamed, if not abolished. Undoubtedly, the relatively modest economic retrenchment barely a recession worthy of the name that followed the collapse of the 2000 equity

    bubble reinforced this notion, and thus encouraged the tolerance of higher economic

    leverage. Ironically enough, we can very well ascribe the shallowness of the 2001-03

    recession to the boom in residential real estate borrowing. The severity of the downturn

    was therefore blunted by the application of increased leverage. The better-than-expected

    economic outcome subsequently encouraged the accumulation of even higher leverage.

    Arguably, this self-feeding process has been underway since the start of the Great

    Moderation the phase of declining macroeconomic volatility that began in 1982. One

    does not require a spreadsheet to understand that a system in which higher borrowing

    encourages higher borrowing is necessarily doomed to self-dissolution.

    The credit crunch can therefore be seen as the inevitable denouement of a long-term

    cycle of decreasing economic volatility, a trend that fostered an ever greater illusion of

    future security. The basic cause of the crunch was a critical decrease of what can only be

    described as macro-prudence on the part of most participants in the economy, whether

    borrowers, lenders, regulators or policymakers. We might loosely define the quality of

    macro-prudence as a general heightened awareness of the variability of future outcomes

    and the instability of economic regimes, as well as a specific comprehension of the

    hazards originating in collective behavioural patterns. Or, to put things more bluntly,

    macro-prudence is a sensitivity to the damage that can be wrought by the madness of

    crowds. A great deal of attention has been paid to incentive structures in the financial

    markets, the weakening of credit oversight inherent in the originate and distribute

    lending model, the opacity of structured and derivative products, the economically

    unstable nature of profound current account imbalances and the myopic investor focus

    on quarterly corporate results as proximate causes of the credit crunch. All these factors

    were certainly contributors to the rising tide of excess leverage in both the financial and

    non-financial sectors. However, these elements were all in themselves merely symptoms

    of the single ubiquitous underlying theme of a decline in macro-prudence.

    The persistent lack of severe and prolonged negative economic outcomes from the

    early 1980s onwards progressively reinforced scepticism that such outcomes could

    ever occur. As Figure 30 should illustrate, returns from investment in credit assets over

    the past 25 years have seen steadily positive results, with just the odd year of smalldeclines. Similarly, the financial sectors profitability, shown here as a share of GDP, has

    grown steadily with only few moderate setbacks, at least until the past year.

    Even after allowing for the survivorship bias inherent in such data series, these are hardly

    the type of returns that would encourage an abundance of caution in market participants.

    After all, the last major Western banking crises in the late 1980s and in the first few yearsof the 1990s failed to pose any globally systemic threats. So the lesson accrued over the

    past quarter century was that the financial architecture was unshakeable, immune to the

    downside of the credit cycle. Thus, despite a steady rise in leverage ratios across the

    economy and an astonishing 100 percentage point rise in the us total debt/GDP ratio

    over the past decade the expectation that the aftermath of credit booms might pose

    mortal dangers declined just as steadily as the level of leverage rose.
