Answer:
a) The need to hold liquid reserves
Step-by-step explanation:
Liquid reserves or reserve requirement refers to the amount of cash that banks need to keep in their vaults or the nearest federal reserve bank. The liquid reserve is a requirement by the Federal Reserve. It is set as a percentage of the bank's deposits.
The federal reserves use the reserve requirement as a monetary tool to influence the money supply in the economy. Reserve requirement puts a limit on the amount a bank can loan out. An increase in the percentage of reserve requirement implies that a bank will lend out a lesser proposition of its deposits.
