When the Federal Reserve adjusts the supply of money in an economy, the nominal interest rate changes as a result. When the Fed increases the money supply, there is a surplus of money at the prevailing interest rate. To get players in the economy to be willing to hold the extra money, the interest rate must decrease.

How does increasing the money supply affect the economy?

Effect of Money Supply on the Economy An increase in the supply of money typically lowers interest rates, which in turn, generates more investment and puts more money in the hands of consumers, thereby stimulating spending. Businesses respond by ordering more raw materials and increasing production.

How does supply and demand affect interest rates?

How does increasing the supply of money affect the economy?

Increasing the supply of money is similar to increasing supply of any other asset—it lowers the cost of money. A lower cost of money means interest rates are lower and banks can lend with easier terms. This strategy is used when interest rates approach zero, at which point central banks have fewer tools to influence economic growth.

How does the amount of money affect interest rates?

The current level of liquid money (supply) coordinates with the total demand for liquid money (demand) to help determine interest rates. In the U.S., the money supply is influenced by supply and demand—and the actions of the Federal Reserve and commercial banks.

Interest rates also reflect risk premium—how much risk both borrowers and lenders are willing to take on. In a market economy, all prices, even prices for present money, are coordinated by supply and demand.
