Where Is the Money That Banks Hold for Customers Really Kept?

The money that banks "hold" for customers isn't physically stored in a vault or safe, as might have been thought in the past. Here’s how it works:

Banks operate under a fractional reserve system, which means that only a fraction of the money deposited by customers is kept as liquid reserves (in cash or deposits at the central bank). The rest of the money is lent out to other customers or invested.

The amount of reserves a bank must hold is regulated by the central bank of each country and varies according to local regulations. For example, a bank might be required to hold only 10% of total deposits as reserves.

Most of the money deposited in a bank is used to issue loans to other customers, such as mortgages, personal loans, or business credits. This means that a customer’s money might be "working" in the form of a loan to another customer.

Banks also invest part of the deposits in various financial instruments, such as government bonds, stocks, or even infrastructure projects. These investments generate income for the bank but also carry risks.

A portion of the deposit money is held in the bank's accounts at the country’s central bank (such as the Federal Reserve in the United States or the European Central Bank). These reserves are part of the mechanism central banks use to control the money supply and ensure financial stability.

Most of the customers' money exists as entries in the bank's databases, meaning in the form of electronic or digital money. There isn't a physical equivalent for most of the money in banks; it’s simply an accounting record.

When you make a bank transfer or pay with a card, no physical money moves. Instead, accounting records in the banks' databases are updated.

Banks keep a small amount of cash in ATMs and branches to meet customers' daily withdrawal needs. However, this amount is only a very small fraction of the total deposits.

Central banks oversee and regulate the operations of commercial banks to ensure they maintain sufficient reserves and operate safely.

In many countries, customers' deposits are insured by a government fund, meaning that even if a bank collapses, depositors are protected up to a certain limit.

The money you deposit in a bank isn’t stored in a specific place; it’s distributed in the form of reserves, loans, investments, and electronic entries in the bank’s accounting systems. Banks use deposits to generate income through loans and investments while maintaining a fraction of the funds in reserves to ensure liquidity and comply with regulations. This system allows banks to offer financial services, but it also introduces risks that are managed and regulated by central banks and other financial authorities.
