4. Which of the following is NOT a key function of the Federal Reserve system?

printing currency

Explanation:

The Federal Reserve simply means the United States Central bank. It was put in place by the Congress in order to provide a safer and more stable financial system.

The three main functions of the Federal Reserve include financial services, monetary policy, and banking supervision.

These functions above can be broken down into further functions such as conducting monetary policy, regulating bank activities, providing a system of check collection and clearing, guiding the macroeconomy, dealing with financial crisis etc.

It's not the function of the Federal Reserve system to print currencies. It's the Treasury Department's Bureau of Engraving and Printing that's in charge of the printing.
