Final answer:
A bank with $100,000 in checkable deposits and $15,000 in actual reserves has a money-creating potential of -$5,000 at a 20% reserve ratio and $1,000 at a 14% reserve ratio.
Step-by-step explanation:
To calculate a bank's money-creating potential, we must first determine the required reserves and compare it to the actual reserves. The difference will indicate the potential for additional loans (money creation). When the reserve ratio is 20%, the required reserves for $100,000 in checkable deposits would be 20% of $100,000, which is $20,000. Since the bank has actual reserves of $15,000, it has insufficient reserves and thus no money-creating potential; in fact, it is $5,000 short. If the reserve ratio is 14%, the required reserves would be 14% of $100,000, which is $14,000. With $15,000 in actual reserves, the bank exceeds the required amount by $1,000, representing its money-creating potential.
