Answer:
$500 million
Explanation:
The solution of the money supply and its effect is here below:-
Decrease in money supply = $50 million ÷ reserve ratio
= $50 million ÷ 10%
= $500 million
If $50 million were used to repay loans, that will have raised money supply. Thus, buying $50 million in government securities from the fed reduces the supply of capital.
