Excess Reserves Example
How to calculate excess reserves?
- First, determine the total amount of reserves.
Measure or calculate the total amount of reserves currently held by the bank. For this example we will say the bank has $1,000,000.00 in reserve.
- Next, determine the required reserves.
Based on the laws of the country, determine the required amount of reserves that need to be held. We will assume this is $500,000.00.
- Finally, calculate the excess reserves.
Using the formula, we find the excess reserves to be, $1,000,000 – $500,00 = $500,000.
Excess reserves are the amount of extra currency/money a central regulatory bank has over the reserve amount required by law.
Central banks and regulatory authorities are often required to keep a certain amount of money on hand as reserves in case of emergency.
