A. Calculate the currency-to-deposit ratio (c), the excess-reserves-to-deposit ratio (e) and the money multiplier (m) given the following values:
rr = 0.20 C = $320 billion D = $1,000 billion ER = $60 billion
B. Calculate total required reserves (RR), total actual reserves (AR) and the monetary base (MB).
C. Now assume the FED lowers the required reserve ratio to 0.10. Calculate the new money multiplier (m’) and the new money supply (M1).
D. Calculate the new level of deposits (D’) and currency in circulation (C).
E. Calculate the new level of required reserves (RR’) and excess reserves (ER’).
A. Calculate the currency-to-deposit ratio (c), the excess-reserves-to-deposit ratio (e) and the money multiplier (m) given the following values:
rr = 0.20 C = $320 billion D = $1,000 billion ER = $60 billion
currency-to-deposit ratio = C/D = 320/1000 = 32%. or 0.32
excess-reserves-to-deposit ratio = ER/D = 60/1000 = 6%
Money multiplier = (1 + c)/(rr + c + e) = (1 + 0.32)/(0.20 + 0.06 + 0.32) = 2.2758
B. Calculate total required reserves (RR), total actual reserves (AR) and the monetary base (MB).
Total required reserve = 20% of deposits = 20% of 1000 = 200 billion
Total reserves = RR + ER = 260 billion
Monetary base = currency + reserves = 320 + 260 = 580 billion
C. Now assume the FED lowers the required reserve ratio to 0.10. Calculate the new money multiplier (m’) and the new money supply (M1).
New money multiplier = (1 + 0.32)/(0.10 + 0.06 + 0.32) = 2.75
Money supply = monetary base x multiplier = 580 x 2.75 = 1595 billion
D. Calculate the new level of deposits (D’) and currency in circulation (C).
C + D = 1595 billion
C/D = Assuming it to be unchanged = 32% so C = 32% of D
0.32D + D = 1595 billion
Hence Deposits = 1208.33 billion
Currency =386.67 billion (32%)
E. Calculate the new level of required reserves (RR’) and excess reserves (ER’).
RR = 10% of 1208.33 billion = 120.83 billion
ER = 6% of 1208.33 billion = 72.5 billion.
