Answer:
B) 4
Explanation:
the monetary multiplier before this newly acquired checkable deposit was 1 / required reserve ratio = 1 / 20% = 5. Since the banks decided to increase the reserve ration to 25%, then the money multiplier will decrease to 1 / 25% = 4.
The monetary multiplier shows the money creating effect of the fractional banking system. E.g. you deposit $1,000 at bank A. Bank A will lend $750 to Bill. Bill then purchases a bike from Tom and Tom deposits the $750 in bank B. Bank B will then lend $562.50 to Sarah. Sarah purchases a TV from Alex, and Alex deposits the money in bank C. Then bank C will lend $421 to Frank, and the cycle goes on.
