Answer:
rises; decreases
Explanation:
When the Fed sells US securities, it is engaging in a contractionary monetary policy. This means that they are trying to cool down the economy and lower inflation rate by reducing the money supply. This will lead to an increase in the federal funds rate and the whole economy's interest rates.
Since the Fed absorbs money from the banks and other investors, the quantity of banks' reserves decreases, which leads to less loans and higher interest rates charged.
