Answer:
Provide a device through which the credit-creating activities of banks can be controlled
Step-by-step explanation:
The legal reserve requirement is the minimum amount mandated by Central banks for banks to have as their minimum reserves.
The legal reserve requirement is used by the government as a means to control the supply of money in the economy.
If the central bank wants to reduce money supply, it increases the legal reserve requirement and if it wants to increase money supply, it reduces the legal reserve requirement.
A high reserve requirement reduces the amount that banks can make available for loans.
