You take $200 you had kept under your mattress and deposit it in your bank account. Suppose this $200 stays in the banking system as reserves and banks hold reserves equal to 20 percent of deposits.
The total amount of deposits in the banking system increases by _____ , and the money supply increases by _____.
The total amount of deposits in the banking system increases by 1000 , and the money supply increases by 800.
Reason:
Increase in Deposits = Money Multiplier x Deposit.
=1/Reserve Ratio x Deposit
=1/.20 x $200
= $1000
Because deposits increase by $1,000 but currency declines by $200, this means the money supply increases by $1,000−$200=$800.
