DETERMINING THE LEVELOF INTEREST RATES
•Interest rate is the price of borrowing money. The level dependson supply and demand for loanable funds
•2 ways to assess the demand/supply for loanable funds:
•Bond market perspective
•Loanable fund perspective

Loanable Funds Theory
Market interest rate is determined by the factors that control
supply of and demand for loanable funds.

Demand for Loanable Funds
1. Household demand for loanable funds
-For purchases of house, automobiles, household items
-Inverse relationship between the interest rate and the quantity of loanable
funds demanded.-HHs demand greater qtty of loanable funds at lower rates of interest
2. Business demand for loanable funds
-Depends on number of business projects to be implemented.
-More demand at lower interest rates-cost of borrowing
3. Government demand for loanable funds
-Interest inelastic: insensitive to interest rates.
-Expenditures and tax policies are independent of the level of interest rates

Demand for Loanable Funds
4. Foreign demand for loanable funds
-A country’s demand for foreign funds depends on the interest rate
differential between the two.
-The greater the differential, the greater the demand for foreign funds.-The quantity of U.S. loanable funds demanded by foreign governments will
be inversely related to U.S. interest rates.
5. Aggregate demand for loanable funds

Supply of Loanable Funds
1. Households are largest supplier, but some supplied by
government units.
2. More supply at higher interest rates.
3. Supply by buying securities.
4. Effects of the Fed: By affecting the supply of loanable
funds, Fed’s monetary policy affects interest rates.
5. Aggregate supply of funds

Equilibrium Interest Rate
1. Aggregate Demand for funds ( D A) D A = Dh + Db + D g + Dm + D f
Dh = household demand for loanable funds
Db = business demand for loanable funds
D g = federal government demand for loanable funds Dm = municipal government demand for loanable funds
D f = foreign demand for loanable funds
2. Aggregate Supply of funds (S A)S A = S h + S b + S g + S m + S f
S h = household supply for loanable fundsS b = business supply for loanable funds
S g = federal government supply for loanable funds
S m = municipal government supply for loanable funds
S f = foreign supply for loanable funds

Explaining Changes
in Equilibrium Interest Rates
• Factors affecting change in supply and demand
for loanable funds
• The underlying economic forces that cause achanges in SS and DD for loanable funds
1. Economic conditions
2. Inflation3. Monetary policy
4. Budget deficit
5. Foreign flows of funds

Impact of Inflation onInterest Rates
Fisher hypothesis: the relationship between interest rate andexpected inflation
Nominal interest rate compensate savers in two ways: (i)compensate savers reduced purchasing power, (ii) Provide an
additional premiun for savers to forgo current consumption in = ir + expected inflation
So,
The real interest rate is the difference between nominalinterest rate minus expected inflation. Real interest rate more accurately reflects true cost of borrowing
When real rate is low, greater incentives to borrow and less to lend
Real interest rate more accurately the true return to saving

Summary of the Fisher Effect
1. If expected inflation rises from 5% to 10%, the expectedreturn on bonds relative to real assets falls and, as aresult, the demand for bonds falls
2. The rise in expected inflation also means that the realcost of borrowing has declined, causing the quantity ofbonds supplied to increase
3. When the demand for bonds falls and the quantity ofbonds supplied increases, the equilibrium bond price falls
4. Since the bond price is negatively related to the interestrate, this means that the interest rate will rise

Impact of Monetary Policy onInterest Rates
1. Central banks (CBs) can affect the supply on loanablefunds – When CBs increase money supply, it increases the supply of
loanable funds, placing downward pressure on interest rates
– When CBs decrease money supply, it decreases the supply of loanablefunds, placing upward pressure on interest rates

Impact of Budget Deficit onInterest Rates

2. Government demand loanable funds

Impact of Foreign Flows ofFunds on Interest Rates
1. Interest rates also determined by demand for fundsdenominated in that currency and supply of fundsavailable in that currency
2. Massive flows of funds between countries-give impact onsupply of loanable funds, affecting interest rates
3. Shifts in supply are driven by large institutional investorsseeking for high returns on their investments
