Answer:
$5 million
Explanation:
Open market operations is a monetary policy instrument used by the central bank of a nation to control the money supply in an economy. So, if Fed wants to contract the money supply then it must sell the bonds in the market.
Reserve requirement = 10%
Multiplier = 1 ÷ Reserve requirement
= 1 ÷ 10%
= 10
So, in order to contract the money supply by $50 million, the amount of bonds needs to be sold will be $50/10 = $5 million.
