What tool does the federal reserve use to influence the volume of money in the economy by buying and selling government securities

Open market

Explanation:

The open market is a monetary policy tool that the Federal Reserve uses to manipulate the amount of currency in circulation in the economy to stimulate or slow the economy. When the economy is in inflation, the Federal Reserve sells government securities, wiping the economy's monetary base. With less currency in circulation, inflation decreases. In contrast, when the Federal Reserve wants to stimulate the economy, it sells government securities by injecting money into the economy. Thus consumption increases and the economy improves.
