How FDIC Insurance Works, and How to Protect More Than $250,000

Federal Deposit Insurance Corporation coverage protects your money at an insured bank up to $250,000 per depositor, per bank, per ownership category. That last phrase is the one most people miss, and it is why a single household can safely hold well over the headline number at one institution without stepping outside the deposit insurance umbrella.

This page explains how the rule works, walks through a practical example, and lays out concrete ways to cover a balance larger than a quarter million dollars.

What the $250,000 limit really covers

FDIC insurance is a federal guarantee. If an insured bank fails, the government makes depositors whole up to the coverage limit, typically within a few business days. It applies to checking accounts, savings accounts, certificates of deposit, and money market deposit accounts. It does not apply to investments the bank sells through an affiliated brokerage, or to safe deposit box contents.

The $250,000 figure caps how much insurance protects at one bank in one ownership category for one person. It does not cap how much you can deposit. Stack the ownership categories or spread across banks, and the covered total rises accordingly.

The ownership categories that multiply your coverage

The FDIC treats different legal forms of ownership as separate buckets. The main ones a household will use are single accounts, joint accounts, revocable trust accounts (including payable-on-death designations), certain retirement accounts such as IRAs, and irrevocable trusts. Each bucket gets its own $250,000 of coverage per owner at each bank.

Joint accounts are especially powerful here because each co-owner is separately insured for their share. A couple holding one joint account is insured for $250,000 for each owner, adding up to $500,000 on that single joint account. That coverage sits entirely apart from whatever each spouse holds in their own individual accounts at the same bank.

Revocable trust accounts, including payable-on-death designations at a regular bank, work by beneficiary. Name eligible beneficiaries on the account and coverage expands per beneficiary. A trust with five named beneficiaries can carry up to $1.25 million of coverage at one institution. The FDIC’s rules on who counts as an eligible beneficiary carry specific requirements, so the account titling and paperwork matter.

A worked example

Take a married couple with about $1 million in cash they want fully insured at one bank. They could structure it like this:

• An individual savings account in the first spouse’s name alone. Insured up to $250,000 as a single account.
• An individual account in the second spouse’s name alone. Insured up to another $250,000 as a single account.
• A joint savings account with both spouses as co-owners. Insured up to $500,000, because each owner receives $250,000 of joint-category coverage.

Three accounts, one bank, one million dollars, every dollar covered. Adding a payable-on-death designation naming their children extends coverage even further at the same institution, without moving a dollar to a second bank.

Using more than one bank

The simplest approach is the oldest: split the money across two or three different insured banks. Each institution provides its own separate coverage. This is why families with sizable cash balances often maintain a primary checking bank, a high-yield online savings bank, and a CD ladder at a third. Each bank represents a fresh $250,000-per-depositor, per-ownership-category allotment.

Two things deserve attention here. Some familiar-looking brands share a single FDIC certificate under the hood, meaning they count as one bank for insurance purposes. Branches of the same bank in different states are still the same bank. The FDIC’s BankFind tool confirms the charter behind any brand name before you commit a large deposit.

Sweep and network deposit programs

Network deposit services solve the problem of insuring a very large balance within a single banking relationship. Programs marketed under names like IntraFi automatically spread your deposits across multiple FDIC-insured banks, protecting millions without you managing dozens of accounts yourself. You see one statement and one balance. Behind the scenes the money is distributed so every dollar stays inside FDIC coverage at one of the participating institutions.

Brokerage cash sweeps often work the same way. The brokerage routes idle cash into program banks, each providing its own coverage. Read the disclosure carefully. Some sweeps use only a handful of banks, which caps the effective coverage, while others use dozens.

FDIC for banks, NCUA for credit unions

Credit unions are not covered by the FDIC. They are covered by the National Credit Union Share Insurance Fund, administered by the National Credit Union Administration. The rules mirror FDIC coverage almost exactly, including the $250,000 per owner per ownership category structure. Both guarantees carry the full faith and credit of the United States government behind them.

What is not a deposit

A brokerage money market mutual fund is a securities product, not a bank deposit, and it is not FDIC insured regardless of how stable its share price appears. It carries SIPC protection against the failure of the brokerage itself, but not against a decline in the fund’s value.

A money market deposit account at a bank is a deposit and is covered like any other savings account. The easiest test: if a product’s disclosure calls it a fund, it is not a deposit. If it identifies itself as an account at a named FDIC bank, it is a deposit and qualifies for coverage.

How to think about placing a large cash balance

Coverage sets only the floor of the decision. Yield still matters. The national average interest rate on a 12-month CD stood at 1.71% in August 2026, which reflects industry baseline rather than competitive pricing. Top CD yields were running close to 4.00% APY in mid-2026, and every one of those accounts can be structured to stay inside the insurance limits using the same category and multi-bank tools described above. The Federal Reserve held the federal funds rate in the 3.50% to 3.75% range as of late July 2026, which sets the broad backdrop for what deposit accounts are paying.

Before parking cash based on rate alone, confirm the institution is FDIC or NCUA insured, decide which ownership categories fit your household, and use the FDIC’s Electronic Deposit Insurance Estimator (EDIE) to verify the coverage math on the exact account titling you plan to use.

Common mistakes that quietly break coverage

Titling every account in the exact same name at the same bank collapses the entire balance into one single-owner category and caps coverage at $250,000 regardless of how many separate accounts you open.

Assuming a trust automatically extends coverage is another common error. The trust has to be a qualifying revocable or irrevocable trust with named eligible beneficiaries, and the account must be titled correctly for the separate coverage buckets to apply.

Treating brokerage money market funds as bank deposits is a third mistake. They are not, and no amount of FDIC signage in a brokerage lobby changes that. Finally, do not forget accrued interest. Coverage includes both principal and accrued interest earned up to the failure date, so a CD sitting right at the cap can slip over the limit as interest posts.

Frequently asked questions

Has the $250,000 standard coverage limit changed?

The limit has been in place since October 2008, when it was permanently increased from the previous $100,000 limit during the financial crisis. The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 made the increase permanent. Congress could change it: a bipartisan group of senators reintroduced the Main Street Depositor Protection Act in March 2026, which would direct the FDIC to set a new cap between $250,000 and $5 million of coverage for noninterest-bearing transaction accounts at eligible banks and credit unions. The bill had not passed as of mid-2026, so confirm the current figure on the FDIC’s own site before making a large placement decision.

Does opening more accounts at the same bank increase my coverage?

Only if the additional accounts are in different ownership categories or add eligible beneficiaries. Two single-owner savings accounts in your name at the same bank share one $250,000 cap. A single account plus a joint account plus a payable-on-death account are three separate buckets, each with its own coverage ceiling.

Are IRAs at a bank insured separately from my regular savings?

Yes, when they hold deposit products like CDs or savings accounts. Certain retirement accounts form their own ownership category with a separate $250,000 limit per bank. IRAs invested in mutual funds or securities through a brokerage are not deposits and are not FDIC insured.

What happens to my money if an FDIC bank actually fails?

When a bank fails, the FDIC is appointed receiver. It steps in, assumes control of the bank’s assets and liabilities, and either sells the institution to an acquiring bank or directly pays insured depositors. In practice, bank failures are often handled so smoothly that many depositors experience little more than a change of logo on their debit card. Depositors keep principal and accrued interest up to the coverage limit.

Is a credit union as safe as a bank?

A federally insured credit union carries NCUA coverage that mirrors FDIC coverage in structure and dollar limit. Both are backed by the full faith and credit of the United States. The differences between banks and credit unions show up in products, rates, and membership rules, not in the underlying insurance guarantee.
