Explain what is meant by the phrase "a bank's balancing act."

What will be an ideal response?

Banks accept deposits and make loans with the funds they receive from the deposits. Banks profit if the interest rate they charge on their loans exceeds the interest rate they pay on their deposits. Loans are made for a specified length of time and cannot be called in before they are due. However, deposits can be withdrawn at any time by the depositors. Therefore a bank must perform a balancing act: It is risky to lend too much of the deposits and run the risk of mass withdrawals that would create a crisis for the bank. However, it is by making loans that the bank earns a profit.
