Hi there
If the Federal Reserve decides to lower the reserve ratio through an expansionary monetary policy, commercial banks are required to hold less cash on hand and are able to increase the amount of loans to give consumers and businesses. This increases the money supply, economic growth and the rate of inflation.
Amount to be loan out at 4% reserve
55,000÷0.04=1,375,000
Amount to be loan out at 2% reserve
55,000÷0.02=2,750,000
It increase by
2,750,000−1,375,000
=1,375,000. ..answer
Hope it helps
