Reserve Ratio/Requirement

Definition

The reserve ratio, also known as the reserve requirement, refers to the percentage of deposits that banks are required to hold in reserves. It is set by the central bank and helps regulate the amount of money banks can lend out.

Analogy

Imagine you have a piggy bank where you keep your savings. Your parents tell you that you must always keep 20% of your savings in your piggy bank and can only spend the remaining 80%. This is similar to how banks have to keep a certain percentage of their deposits as reserves.
