DETERMINATION OF INTEREST RATES

1

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

2. Can be used to explain:

a. Movements in the general level of interest rates in a particular country

b. Why interest rates among debt securities of a given country vary.

2

1. Household demand for loanable funds

a. Households demand loanable funds to finance housing expenditures as well as the purchase of automobiles and household items.

b. Inverse relationship between the interest rate and the quantity of loanable funds demanded.

3

2. Business demand for loanable funds

a. Depends on number of business projects to be implemented. More demand at lower interest rates. (Exhibit 2.2)

3. Government demand for loanable funds

a. Governments demand loanable funds when planned expenditures are not covered by incoming revenues.

b. Government demand is said to be interest inelastic: insensitive to interest rates. Expenditures and tax policies are independent of the level of interest rates. (Exhibit 2.3)

Interest Rates reflect the cost of credit (borrowing).

The movement of interest rates is determined by: Supply of Credit and the Demand for same.

Increases in supply, ceteris paribus, leads to lower interest rates. Increases in Demand, ceteris paribus, leads to higher interest rates.

Interest rates are positively affected by inflationary expectations (in a free and efficient market):

-> Inflation ↑ Rates ↑

Interest rates are also affected by risk perceptions

1. Households are largest supplier, but some supplied by government units.

a. More supply at higher interest rates.

b. Supply by buying securities.

2. Effects of the Fed - By affecting the supply of loanable funds, the Fed’s monetary policy affects interest rates.

3. Aggregate supply of funds –Is the combination of all sector supply schedules along with the supply of funds provided by the Fed’s monetary policy. (Exhibit 2.6)

• Impact of Monetary Policy on Interest Rates

• When the Fed reduces (increases) the money supply, it reduces (increases) the supply of loanable funds, putting upward (downward) pressure on interest rates.

• Impact of the Budget Deficit on Interest Rates

• Crowding-out Effect: Given a certain amount of loanable funds supplied to the market, excessive government demand for funds tends to “crowd out” the private demand for funds. (Exhibit 2.11)

• Impact of Foreign Flows of Funds on Interest Rates

• Interest rate for a certain currency is determined by the demand for funds in that currency and the supply of funds available in that currency. (Exhibit 2.12)

1. Net Demand (ND) should be forecast:

ND = DA – SA

ND = (Dh + Db + D,m + Dr) – (Sh + Sb + Sm + Sf)

2. Future Demand for Loanable Funds depends on futurea. Foreign demand for U.S. fundsb. Household demand for fundsc. Business demand for fundsd. Government demand for funds

3. Future Supply of Loanable Funds depends on:a. Future supply by households and othersb. Future foreign supply of loanable funds in the U.S.

11

1. Impact of economic growth on interest rates:

a.Puts upward pressure on interest rates by shifting demand for loanable funds outward. (Exhibits 2.8 & 2.9)

2. Impact of inflation on interest rates:

a.Puts upward pressure on interest rates by shifting supply of funds inward and demand for funds outward. (Exhibit 2.10)

b.Fisher effect: i = E(INF) + iR

where i = nominal or quoted rate of interest

E(INF) = expected inflation rate

iR = real interest rate12

Households are net suppliers of funds.

Governments may also supply funds* The Fiscal Year 2009 Stimulus generated approximately

$800 Billion in credit (debt).

Federal Reserve Monetary Policy Reduce reserve requirement Buy Securities from member banks

Households Consumption above current income levels financed with

borrowing.B

usiness Finance asset expansion.

Government Cover expenditures in excess of tax receipts. Demand for funds Inelastic with respect to rates.

Foreign Same reasons as "A" and "B" as well as "C" Additional sources of [FOREX] risk

14

Equilibrium = point at which markets clear (no excess supply or demand). Question: Is an equilibrium point observable? Question: Is equilibrium an important concept?

Changes in the Equilibrium Interest Rate Change in response to changes in supply of funds Change in response to changes in demand for funds

The Fisher Effect Preserving Purchasing Power Components of the Nominal Rate of Interest

15

Government Budget Deficits and Interest Rates Does government competition for loanable funds increase the

cost? What arguments support deficit spending?

Impact of Foreign Interest Rates Mobility of international capital → domestic rates Differences in international investment opportunity sets

Impact of Exogenous Events on Interest Rates Unexpected international events: wars and rumors of war Sovereign debt crises

16

Factors in forecasts: (see Ex 2.14) Foreign demand (vs. foreign supply) Household demand (vs. household supply) Business demand

Depends on investment opportunity set Government demand

Fiscal Policy drives borrowing Fiscal Policy a function of economic policy goals

17

Whom demands and supplies funds in the Loanable Funds Theory?

How does the supply of and demand for money [credit] impact interest rates?

What causes changes in interest rates?

What is the Fisher Effect and why is it important?

What exogenous forces affect interest rates?
