a. Fed's bond purchase increases money supply, lowers interest rates. Demand for money may decrease, illustrated by the liquidity preference theory.
b. Increased credit-card availability reduces money demand, potentially lowering interest rates due to decreased need for cash holdings.
c. Fed reducing reserve requirements increases money supply, potentially lowering interest rates by injecting more liquidity into the market.
d. Household preference for more cash increases money demand, potentially raising interest rates due to higher demand for liquidity.
e. Optimism boosts business investment, increasing demand for loans and money. Money supply may rise, potentially raising interest rates.
The entire amount of cash and other liquid assets in an economy on the measurement date is called the money supply.
All cash on hand as well as bank deposits that account holders may quickly convert to cash are included in the money supply.
Therefore, high-powered money, the currency ratio, the needed reserve ratio, the market interest rate, and the bank rate all influence the amount of money in circulation.
