Every bank must hold a certain amount of cash, known as "required reserves." This amount is set by central banks, like the Federal Reserve in the U.S., and ensures that banks can pay customers who want to withdraw money. Required reserves are determined as a percentage, called the "required reserve ratio," of the bank's total deposits. This means a bank cannot lend out all the money deposited with it; a part of it must be kept aside as a safety net.
For instance, if a bank's deposits total $100,000 and the required reserve ratio is 10%, the bank must keep $10,000 in reserve and can only lend out the remaining $90,000. This rule helps maintain financial stability by ensuring banks have a steady cash flow to handle withdrawals.

The amount of real money a bank holds at any time is called "actual reserves." These include cash in the bank's vaults, cash on hand, checks that are ready to be drawn, and deposits at the central bank. Actual reserves show how much money a bank can use to meet withdrawal demands, pay off debts, or make new loans.
For example, if a bank has $12,000 in cash, $5,000 in checks, and $8,000 in deposits at the central bank, then its actual reserves total $25,000.

• This ensures the bank can cover its financial responsibilities.
• Helps in determining how much it can lend or invest beyond required reserves.

After meeting the required reserves, the extra money a bank holds is known as "excess reserves." These are crucial because they provide the bank with a cushion for unexpected withdrawal requests or investment opportunities. Excess reserves represent the amount that a bank can safely use for lending or investing without risking its ability to meet customers' withdrawal demands.
For instance, if the total actual reserves are $25,000 and the required reserves are $10,000, the excess reserves available for lending or investing amount to $15,000.

• Offers a buffer to enhance liquidity.
• Allows banks more flexibility in managing their financial resources.

Central banks regulate the banking sectors to ensure the stability of the financial system. One of their main tools is setting reserve requirements. These requirements dictate how much money a bank must keep in reserve, influencing how much money is available for lending and borrowing.
By adjusting the required reserve ratio, central banks can help control inflation and manage economic growth. A lower reserve ratio can stimulate the economy by allowing banks to lend more money, while a higher ratio may slow down economic activity by restricting the amount that banks can lend.

• Helps maintain a balance between economic growth and price stability.
• Ensures banks remain solvent and prevents financial crises.

By setting these regulations, central banks play a crucial role in maintaining economic stability and public confidence in the financial system.
