I. Currency

Currency is a unit of exchange . It is exchanged for:- goods- services- other currency

Most countries have control over the supply and production of their own currency.

Usually Central Banks or Ministries of Finance control thecurrency.

There are about 175 currencies in current circulation.

There are about 195 countries in the world.

- several countries use the same currencyex: the euro is used by Portugal, Spain, France,

Italy, Ireland, Belgium, Luxembourg, Germany, Netherlands, Austria, Slovenia, Slovakia, Finland,Malta, Greece and Cyprus

- some countries declare another countrys currency to belegal tender

ex: Panama and El Salvador use the US dollar aslegal tender

II. Foreign Exchange

When making international transactions (like paying for imports or buying foreign assets), currencies are exchanged aswell.

A. Exchange Rate Basics

The foreign exchange rate (exchange rate, forex rate, FX rate)specifies how much one currency is worth in terms of another currency. (abbreviated e)

The current exchange rate is also called the spot rate.

With 1 British pound you could get how many US dollars?1.5421

(actually just the reciprocal 1/1.5421 = 0.6485)

You could get this amount of this currency

Using exchange rates to convert prices into another currency:On J une 18, 2007, our meal in Vienna, Austria cost 19.70 andthe exchange rate was 1 USD = 0.73169EUR.

How many US dollars did it cost?

19.70 x 1$ . = $0.73169

$26.92

On August 3, 2005 in Nice, France a kilo of peppers cost 2.20.The exchange rate was 1 EUR = 1.19501 USD.

How much did a kilo of peppers cost in US dollars?

2.20 x 1.19501$ =

B. Exchange Rate Fluctuations:

When one unit of currency A can buy more of currency B, thencurrency A has appreciated versus currency B.

When one unit of currency A can buy less of currency B, thencurrency A has depreciated versus currency B.

For example:7/25/2009 1 USD = 0.718692 EUR 7/25/2010 1 USD = 0.790398 EUR

Has the US dollar appreciated or depreciated versus the euro inthe past year?

dollar has appreciated versus the euro

the euro has depreciated versus the dollar


15/46

15

Some implications of an appreciating currency:- import more (currency is strong, buying power is strong)

- export less- trade balance worsens (more of a deficit, less of a surplus)- travel abroad is cheaper

Some implications of a depreciating currency:

- import less- export more- trade balance improves (less of a deficit, more of a surplus)- travel abroad is more expensive

Economists dont believe that appreciating/depreciating currenciesare inherently good or bad it depends on the circumstances.


16/46

C. Types of exchange rates

floating (aka flexible): the currencys value is determined bymarket forces

fixed (aka pegged): the currencys value is set at a fixed valueof another currency

pegged float: the currencys value is kept within a certain range

of predetermined values with another currency

The Foreign Exchange Market for British pounds(exchange rate between $ and )

Demand for for foreign exchange- investors who have $ and wish to buy -denominated assets- investors who are selling $-denominated assets and wish to

convert back to - US importers of British goods (have $ but need to pay for theorder in )

Supply of for foreign exchange- Investors who have and wish to buy $-denominated assets

- Investors who are selling denominated assets and wish toconvert back to $- British importers of US goods (have but need to pay in $)- government policy (Central Banks or Ministries of Finance),and bank practices

D slopes downward because as the depreciates,it is cheaper to buy using $ (as the price of a

2. Fixed (Pegged) Exchange Rates

Flexible (floating) exchange rates fluctuate with market forces andmay be quite volatile. To reduce the uncertainty associated with afloating forex rate, a country might choose to peg its currency to acertain value.

The main benefit of a pegged exchange rate is stability.- investors are more certain of a return- import/export transactions have less risk

The drawback of a pegged exchange rate is it causes a lack of flexibility for other policies.

- the Central Bank / Ministry of Finance has to take steps tomaintain the peg

- need to have reserves of the currency you are pegging to


23/46

A pegged rate higher than the market rate:

Dkroon

eeuro/kroon

e1

Qd Qs

Suppose Estonia pegs thekroon to the euro at a rate of e1.

- at e1, Qs > Qd which

means there is a surplus of kroon in the market

- normally, the kroon woulddepreciate

-the Estonian Central Bank must intervene to keep thekroon from depreciating

Skroon

Qkroon

Surplus of kroon

overvalued


24/46

The Estonia Central Bank must use its reserve of euros to buy upthe surplus of kroon.

- needs to be willing to do so at the fixed exchange rate

Dkroon

eeuro/kroon

e1

Qd Qs

Skroon

Qkroon

Surplus of kroon

- The Central Bank endsup with more kroon

- Depletes reserves of

euros

Pull kroon out of themarket

Put euros into themarket


25/46

25

Implications:

An overvalued currency can lead to a trade deficit:- decreases exports (they are more expensive)- increases imports (they are cheaper)

It benefits imports at the expense of exports

The Central Bank reduces its foreign exchange reserves.

If a currency is overvalued for a long period of time, then a balance of payments crisis could be on the horizon.

- run out of reserves- cant pay for imports


26/46

26

Options if running out of foreign reserve currency:

- borrow foreign exchange from another central bank or the IMF tomaintain the peg

- re-set the peg to a lower level, more consistent with the marketrate

- allow the exchange rate to depreciate down to the market level


27/46

27

If investors think that a currency will be devalued, they may sell allof their assets in that currency.- the demand for currency falls- This would put more pressure on the peg.

- the market equilibrium is even further below the peg- the surplus is larger

- A government may be forced to devalue the currency.- self fulfilling prophecy

The investors could then move back into the currency, but since it hasdepreciated, they can buy much more of it.

e1

Qs Qd

Suppose China pegs theyuan to the US dollar at arate of e1.

- at e1, Qd > Qs which

means there is a shortageof yuan in the market

- to keep the currencyfrom appreciating, the

central bank must intervene

S

Q

shortage of yuan

The Central Bank must put yuan into the market.- will be spending yuan to buy up dollars- needs to be willing to do so at the fixed exchange rate

- China ends up with morereserves of dollars

Pull dollars out of themarket

Put yuan into themarket


30/46

Implications:

An undervalued currency can lead to a trade surplus:- increases exports

- decreases imports

It benefits exports at the expense of imports

The government will increase its foreign currency reserves.


31/46

31

If a currency is undervalued for a long time, then the governmentmay be forced to expand the domestic money supply to get moredomestic currency.

- domestic inflation

If currency speculators think that the government may re-value thecurrency, then hot money may flow into the country.

- increases demand for the currency- the peg is now even further below market equilibrium

- more of a shortage- need more domestic currency

- inflation increases- the government re-sets the peg higher, or lets the currencyfloat- speculators make a profit


32/46

D. Exchange Rate ChoiceFor the vast majority of countries (except for the very largest

economies), the choice of exchange rate policy is probably their single most important macroeconomic policy decision.

The Mundell-Fleming Trilemma

aka:- The Unholy Trinity- The Incompatible Triangle- The Irreconcilable/Incompatible Trinity

An economy can only have 2 of the following 3 policies at anygiven time:

- fixed exchange rates- control of monetary policy

- free movement in capital markets


33/46

33

Suppose a nation decides to fix its exchange rate.

It can either have free capital markets or control over monetary policy.

If it chooses free capital markets, then monetary policy must beused to keep the peg stable.- capital flows in and out freely --- changes the demand for the currency --- pressure on the peg

If it chooses to keep flexibility in monetary policy, then it has to putrestrictions on capital flows.


34/46

34

For nations with small or underdeveloped capital markets (mostnations), it is usually impossible to have

- free capital markets- floating exchange rate- control of monetary policy

The choice is usually either - capital restrictions- floating exchange rates- control of monetary policy

Or - free capital markets- fixed exchange rates- no control of monetary policy


35/46

35

Free movement of capital is one of the Four Freedoms in theEuropean Union.

When a nation pegs to the euro and has open capital markets, thenit must give up control monetary policy.

E. Historical EU Monetary Developments

1870 - 1914: gold standard- each currency was based on gold- fixed exchange rates between all currencies

1914 1945: great variation- exchange and capital controls- floating exchange rates

1946 1973: Bretton Woods System- commitment to keep currencies convertible for current account transactions- fixed exchange rates


37/46

37

1973-1979: EMS/ERM- European Monetary System creates the ecu- Exchange Rate Mechanism is a system of quasi-fixed exchange rates

Belgium, Denmark, Germany, France, Ireland, Italy,

Luxembourg, Netherlands join EMS/ERM

UK joins EMS only

1981 1986 Greece, Portugal, Spain join EMS

1987 1990 Spain and UK join ERM

1990 Capital controls abolished in EC

1991 The plan for a European Monetary Unionincludes a common currency will use ERM as anentry route.

1992 Portugal joins ERM, UK leaves ERM

1995 Austria, Finland join EMS/ERMSweden joins EMS

1998 European Central Bank is created- euro nations freeze exchange rates on Dec 31

Austria, Belgium, Netherlands, Finland, France,Germany, Ireland, Italy, Luxembourg, Portugal, Spain

III. Fun with Exchange Rates: The Economists Big Mac Index

The index is a lighthearted attempt to gauge how far currencies arefrom their fair value.

It is based on the theory of purchasing-power parity (PPP), which

argues that in the long run exchange rates should move to equalizethe price of an identical basket of goods between two countries.

Our basket consists of a single item, a Big Mac hamburger, produced in nearly 120 countries.

The fair-value benchmark is the exchange rate that leaves burgerscosting the same in America as elsewhere.

To calculate the price in US$:Multiply the local price by the actual exchange rate.

67.6kr x 1$ = $3.43

19.7kr

If you bought a Big Mac in the Czech Republic, it would cost you67.6kr . Which means it really costs you $3.43.

- It is more expensive to buy a Big Mac in the US than Czech..


43/46


US $3.73 $3.73 . . .Czech 67.6kr $3.43 18.1 19.7 - 8Rep _____________________________________________________

To calculate the implied PPP of the US$:Divide the local price in the foreign country by the local price in the US

PPP rate = 67.6 / 3.73 = 18.1


44/46


US $3.73 $3.73 . . .Czech 67.6kr $3.43 18.1 19.7 - 8Rep_____________________________________________________ Compare the PPP rate to the actual exchange rate to see if the currencyis over or undervalued versus the US$.

To calculate how much the real is overvalued by:

(PPPrate actual exchange rate) / actual exchange rate x 100(18.1 19.7) / 19.7 x 100 = -8.12

Because the koruna is undervalued vs the dollar, we expect the koruna

to appreciate vs the dollar in the future.


45/46

Given the price inlocal currency andthe actual exchangerate, you cancalculate

- price in dollars

- implied PPP rate- over/under

valuation


46/46

Summary:

The exchange rate is also called the spot rate.

Countries can choose to have a pegged exchange rate or afloating exchange rate.

If a nation pegs its exchange rate to another currency, it must be prepared to buy and sell currency as needed to maintain the peg.

The EU has a long history of both fixed and floating exchange

rates.

The Big Mac Index is a way of predicting currency appreciationsand depreciations.
