A capital account is the section of a bank's balance sheet that shows how much money the owners have invested in the bank, plus any profits the bank has earned and kept rather than paid out
Think of it this way: when you start a business, you put in your own money to get it going. That money is your capital. A bank does the same thing. The owners (which might be a single person, a group of partners, or shareholders) put money in to start the bank and keep it running. The capital account tracks that original investment, plus any earnings the bank has decided to reinvest rather than distribute to owners as dividends.
For you as a customer, the capital account matters because it is one way to measure whether a bank is financially stable. A bank with a strong capital account has more of its own money cushioning it against losses. That cushion protects your deposits if something goes wrong.
Key Takeaways
- A capital account shows the owners' stake in a bank — the money they invested plus retained earnings — and appears on the bank's balance sheet, not on your personal account statement.
- Banks are required by regulators to maintain a minimum capital level relative to the loans and investments they make, which is called a capital ratio.
- A stronger capital account generally means a bank has more financial cushion and is less likely to fail, which protects your deposits.
- You will not see your bank's capital account on your own statements; it is part of the bank's financial reporting to regulators and the public.
How a bank's capital account differs from your personal account
Your bank account — whether it is a checking account, savings account, or money market account — is a liability on the bank's books. That sounds backwards, but it is accurate: the bank owes you that money. You own it; the bank is holding it.
The capital account is the opposite. It belongs to the bank's owners, not to customers. It is the owners' equity in the bank itself. When you deposit money, none of it goes into the bank's capital account. Your deposit stays in a separate category called customer deposits or liabilities. The capital account only grows when owners invest new money or when the bank earns a profit and decides to keep it rather than pay it out.
Why regulators require banks to maintain capital
Banking regulators — primarily the Federal Reserve, the Office of the Comptroller of the Currency (OCC), and the Federal Deposit Insurance Corporation (FDIC) — set minimum capital requirements. These requirements exist because a bank with too little of its own money at stake is more likely to take dangerous risks.
The logic is straightforward: if a bank has very little capital, the owners have little to lose if the bank fails. They might be tempted to make risky loans or investments because they are not risking much of their own money. Customers and the government bear the risk instead. By requiring banks to maintain a certain level of capital relative to their loans and investments, regulators force owners to have real skin in the game.
These requirements are expressed as ratios. For example, a bank might be required to maintain a capital ratio of 10 percent, meaning that for every dollar of loans and risky assets the bank holds, it must have at least 10 cents of capital. The exact requirement varies depending on the bank's size and the types of assets it holds.
What happens when a bank's capital falls too low
If a bank's capital account shrinks — usually because the bank has suffered losses — regulators step in. The bank might be required to stop paying dividends to shareholders, raise new capital by selling stock, or reduce the size of its loan portfolio. In extreme cases, if a bank's capital falls below zero (meaning liabilities exceed assets), the bank is technically insolvent and regulators will typically close it or arrange a merger with a stronger bank.
This is where deposit insurance comes in. The FDIC insures deposits up to $250,000 per depositor per bank. If a bank fails, the FDIC uses its own funds to pay depositors, not the failed bank's capital account. The capital account is meant to prevent failure in the first place by ensuring the bank has a financial cushion.
How to find a bank's capital information
If you want to know how strong a bank's capital position is, you can look at its financial statements, which are public documents. Large banks file quarterly and annual reports with the SEC (Securities and Exchange Commission). Smaller banks file reports with their primary regulator — the Federal Reserve, the OCC, or state banking authorities.
You can also use tools like the FDIC's Bank Find tool or BankTracker, which summarize key financial metrics including capital ratios. These tools let you compare banks and see at a glance which ones have stronger capital positions. A bank with a capital ratio well above the regulatory minimum is generally a safer choice than one barely meeting the requirement.
Capital accounts in different types of banks
The structure of a capital account depends on the bank's ownership. In a traditional stock bank, the capital account includes common stock (shares owned by investors), retained earnings (profits the bank kept), and sometimes preferred stock (a hybrid security between stock and debt). In a mutual bank or credit union, there are no shareholders, so the capital account is built entirely from retained earnings and member contributions.
Community banks and credit unions often have smaller capital accounts than large national banks, but they are still required to meet the same regulatory minimums. The difference is that a small bank's capital might represent a larger percentage of its total assets, making it proportionally stronger even if the absolute dollar amount is smaller.
Why this matters to you as a customer
You do not need to monitor your bank's capital account constantly, but it is worth checking occasionally if you keep a large balance or if you are choosing between banks. A bank with a solid capital position is less likely to fail, which means your deposits are safer even if they exceed the FDIC insurance limit. It also suggests the bank is well-managed and not taking excessive risks with customer money.
If you ever see news that a bank's capital ratio has fallen sharply or that regulators have taken action against a bank, that is a signal to move your money to a safer institution. You do not have to wait for a failure; you can act as soon as you see warning signs.
Frequently Asked Questions
Is my deposit part of the bank's capital account?
No. Your deposit is a liability on the bank's balance sheet — money the bank owes to you. The capital account belongs only to the bank's owners and includes their investments and the bank's retained profits.
What is the difference between capital and reserves?
Capital is the owners' stake in the bank. Reserves are funds the bank sets aside to cover potential losses from bad loans or other problems. Both are important to a bank's stability, but they serve different purposes and are tracked separately.
Can a bank fail if it has a strong capital account?
It is unlikely but not impossible. A strong capital account protects against losses, but a bank can still fail if it faces a sudden crisis — such as a bank run where all customers try to withdraw money at once — or if it makes catastrophic business decisions. Capital is a cushion, not a may provide.
How do I know if my bank is safe?
Check the FDIC's Bank Find tool or your bank's latest financial report to see its capital ratio. A ratio above 10 percent is generally considered healthy. You can also verify that your bank is FDIC-insured and that your deposits fall within the $250,000 insurance limit per account type.
Do credit unions have capital accounts?
Credit unions do not have shareholders, so they do not have capital in the traditional sense. Instead, they build equity through member deposits and retained earnings. Regulators still require credit unions to maintain minimum capital ratios, and the NCUA (National Credit Union Administration) insures member deposits up to $250,000.
