Demand Deposit

What Is a Demand Deposit?

A demand deposit is money a bank holds for a customer that can be withdrawn or transferred whenever the customer asks, without the bank needing advance notice. The most familiar example is a checking account. The name reflects the fact that the bank must repay these funds "on demand."

From the depositor's point of view, the money is highly accessible. It can be spent with a debit card, paid out by check, sent through an electronic transfer, or withdrawn at a branch or ATM. Because of this easy access, demand deposits offer a high degree of liquidity, meaning they can be turned into spendable cash quickly and without loss of value.

How Banks Use Demand Deposits

For the bank, a demand deposit is a liability, since the bank owes the money back to the customer. Banks do not keep all of this money idle. They lend much of it out and hold back a portion as reserves to meet withdrawals. This practice is known as fractional reserve banking. Because depositors can leave at any moment, banks must manage this balance carefully.

Demand deposits have historically paid little or no interest compared with time deposit|time deposits, such as certificates of deposit, which lock up funds for a set period in exchange for higher rates. The trade-off is flexibility on one side and potentially higher earnings on the other.

Why Demand Deposits Matter

Demand deposits are a major part of the money supply. In the United States, they are included in the measure known as M1, alongside physical cash. Many countries run deposit insurance systems that cover eligible demand deposits up to set limits. In the United States, this role is played by FDIC insurance, which helps protect depositors if a bank fails.

For individual investors, demand deposits are typically where cash for everyday spending and emergency needs is kept. They are generally not designed for growth, so their role is usually liquidity and stability rather than return.
