The Monetary Policy Transmission Mechanism: Credit Channels

Bank Lending and Balance Sheet Channels

• By altering the supply of funds to the banking system, policymakers can affect banks' ability and willingness to lend

• an open market purchase has a direct impact on the supply of loans, increasing their availability to those who depend on banks for financing

• as interest rates fall, the supply of loans increases

The Monetary Policy Transmission Mechanism: Asset Price Channels

Investment and Wealth

• a fall in the interest rate – pushes stock prices up – drives the mortgage rate down leading to higher demand for

residential housing, driving up the prices of existing homes

• Higher asset prices mean increased wealth and higher consumption

• Why did Japan’s economy fail to respond to interest rates near zero?

• One possibility is that the stock market collapse lowered borrower net worth

• In addition, with borrowers unable to repay, banks had virtually no capital and could not make additional loans.

The Challenges Modern Monetary Policymakers Face: Estimating Potential

During the late 1990s, people failed to recognize potential output was growing more rapidly than it had earlier. As a result, forecasts of GDP were consistently too low.

• Computing real returns means subtracting inflation from nominal returns

• In order to evaluation nominal interest rates, wage increase and the like, you need to know the level of inflation

The Challenges Modern Monetary Policymakers Face: Deflation

Deflation & Zero Nominal Interest Rate Bound:

– Nominal interest rates can't fall below zero– This places a restriction on what monetary

policymakers can do – The most effective way to expand the monetary

base when the overnight interest rate has fallen to zero is to shift to targeting longer-term rates.

The Challenges Modern Monetary Policymakers Face: Booms and Busts

Booms & Busts in Equity & Property Prices

Bubbles that inflate and then burst are particularly damaging, because the wealth effects they create cause consumption to explode and then contract just as rapidly.
