Banks keep between 2 and 10 percent of their total deposits in physical cash on hand

The exact amount varies by bank size, location, and the day of the week. A small community bank might hold 5 percent of deposits as cash, while a large national bank might hold closer to 2 percent. The Federal Reserve does not set a single required amount — instead, banks calculate how much cash they need based on customer withdrawal patterns, local demand, and their own risk management.

Most of a bank's money sits in other forms: loans to customers, investments in securities, and reserves held at the Federal Reserve itself. The cash in the vault is there to cover daily withdrawals. When that cash runs low, the bank orders more from the Federal Reserve, usually within 24 hours.

This is why you can withdraw money at an ATM or teller window almost any time — the bank has already predicted how much you and other customers will need and stocked the vault accordingly. But if an unusually large number of people try to withdraw money at once, the bank can run short temporarily.

Key Takeaways

  • Banks hold 2 to 10 percent of customer deposits as physical cash, with the exact amount depending on the bank's size and local withdrawal patterns.
  • The Federal Reserve does not mandate a specific cash reserve percentage; banks decide based on their own demand forecasts and risk management.
  • Most bank money is deployed as loans and investments, not stored in vaults, because cash sitting idle earns no return.
  • Banks can order additional cash from the Federal Reserve within hours if they predict higher-than-normal withdrawals.
  • A bank run — when many customers withdraw money simultaneously — can deplete vault cash faster than the bank can replenish it.

Why banks don't keep all deposits as cash

If a bank kept 100 percent of deposits in the vault, it would earn nothing on that money. Banks make profit by lending deposits out at a higher interest rate than they pay depositors. A bank that holds $100 million in deposits might lend out $90 million to mortgage borrowers, car buyers, and businesses, keeping only $10 million in cash and reserves.

The Federal Reserve requires banks to hold a minimum amount in reserves — but this reserve can be held as cash in the vault or as an account balance at the Federal Reserve itself. The Fed's reserve requirement varies by account type and bank size, but it is typically much lower than the total deposits the bank holds. This is why a bank can lend out the majority of what customers deposit.

Regulators monitor whether banks are holding enough liquid assets (cash or things that can quickly become cash) to survive a sudden spike in withdrawals. This is called the liquidity coverage ratio. A bank that fails this test faces penalties and restrictions on lending.

How much cash is in a typical bank branch

A single branch location holds far less cash than the bank's headquarters or main vault. A neighborhood branch might have $50,000 to $200,000 in the vault at any given time, depending on the branch size and local demand. This cash is split between the teller drawers (usually $3,000 to $10,000 per teller) and the vault itself.

Branch managers order cash from the bank's regional distribution center or main vault based on expected customer traffic. If a branch knows a large employer in the area pays employees on Friday, the manager will order extra cash for Thursday and Friday. If a holiday is coming, the branch might stock up on Monday.

When a branch runs low on cash, an armored truck picks it up and delivers fresh cash, usually within one business day. This is why branches rarely run out of cash during normal business hours — the system is designed to keep up with predictable demand.

What happens when banks face sudden large withdrawals

If a bank experiences a sudden surge in withdrawals — such as during a financial panic or after news of bank trouble — the vault cash can deplete quickly. The bank can order emergency cash from the Federal Reserve's "discount window," a lending program that provides cash to banks in short-term need. This process takes hours, not days.

However, if the withdrawals are so large and fast that the bank cannot replenish cash in time, the bank may have to close temporarily or restrict withdrawals. This happened to some regional banks in 2023 when depositors rushed to withdraw funds after news of bank failures. The banks had the assets to cover the withdrawals eventually, but not the immediate cash on hand.

The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 per account holder per bank, which reduces panic withdrawals because customers know their money is protected even if the bank fails. This insurance system has prevented many potential bank runs since it was created in 1933.

How the Federal Reserve supplies cash to banks

Banks do not print their own cash — they order it from the Federal Reserve. The Fed operates cash distribution centers in major cities across the country. When a bank needs cash, it submits an order, and the Fed delivers it via armored truck, usually within 24 hours.

The Fed charges banks a small fee for this service, which is built into the bank's operating costs. The Fed also removes damaged or worn cash from circulation and replaces it with new bills. A bank might order $500,000 in fresh $20 bills and return $300,000 in damaged bills at the same time.

During high-demand periods like the holidays or tax refund season, banks order more cash than usual. The Federal Reserve anticipates this and increases production and distribution. If a major event like a natural disaster disrupts normal banking, the Fed can mobilize emergency cash shipments to affected areas.

The difference between vault cash and reserve accounts

A bank's vault cash is physical money in the building. A bank's reserve account at the Federal Reserve is an electronic balance — money the bank can access instantly but never physically touches. Both count toward the bank's required reserves, but they serve different purposes.

Vault cash is for customer withdrawals. Reserve accounts at the Fed are for clearing checks, making wire transfers, and settling transactions with other banks. A bank might have $10 million in vault cash and $50 million in its Federal Reserve account. The Fed account is more efficient because the money can move electronically between banks in seconds.

Banks prefer to keep most reserves at the Fed rather than in vaults because the Fed account earns interest (the Fed pays interest on reserve balances), while vault cash earns nothing. This creates an incentive to keep vault cash as low as possible while still meeting customer demand.

How bank size affects cash on hand

Large national banks like JPMorgan Chase or Bank of America hold billions of dollars in total deposits but keep a smaller percentage as physical cash because they have sophisticated forecasting systems and access to emergency funding. A bank this size might hold 2 to 3 percent of deposits as cash.

Small community banks and credit unions often hold a higher percentage — 5 to 10 percent — because they have less access to emergency funding and less ability to predict customer behavior across many branches. A community bank with $100 million in deposits might keep $7 million in cash, while a national bank with $100 billion in deposits might keep only $2 billion.

Online banks that have no physical branches hold almost no physical cash because customers cannot withdraw in person. They rely entirely on electronic transfers and ATM networks. If an online bank customer needs cash, they use an ATM, and the ATM network is supplied by the bank's partner banks or the Federal Reserve's cash distribution system.

Frequently Asked Questions

Can a bank refuse to give me my money if I want to withdraw a large amount?

A bank cannot refuse a withdrawal of your own money, but it can ask for advance notice for very large amounts (typically $10,000 or more). This gives the bank time to order cash from the Federal Reserve. The bank must complete the withdrawal within a reasonable time, usually one to three business days.

What happens to my money if the bank runs out of cash?

The bank will not run out of cash in the sense of being unable to pay you. If the branch vault is empty, the bank will order cash from its regional center or the Federal Reserve. If the entire bank fails, the FDIC takes over and pays you up to $250,000 per account. Your money is protected either way.

Do banks keep more cash during certain times of year?

Yes. Banks stock up before holidays, tax refund season, and the start of school. They also increase cash on hand before major events like Black Friday or the end of the month when many people receive paychecks. The Federal Reserve increases cash production during these periods to meet demand.

Why do ATMs sometimes run out of money?

ATMs run out of cash when more people withdraw money than the bank predicted. The bank refills ATMs based on historical usage patterns, but unusual events (a local employer laying off workers, a major retailer closing) can throw off the forecast. The ATM operator usually restocks within 24 hours.

Is my money safer if I keep it in cash at home instead of a bank?

No. Cash at home can be stolen, lost in a fire, or damaged. Bank deposits are insured by the FDIC up to $250,000, and banks have security systems and insurance. The only reason to keep cash at home is for immediate access in an emergency, not for safety.
