Putting your money with one of the largest banks generally means you’ll have more access to in-person services at branches, a large ATM network and a wide array of products and services, which can be convenient if you’re looking to do all your banking in one place.

To find the largest banks in the U.S., we looked at domestic asset sizes of institutions that serve both consumers and small businesses. A bank’s assets include the amount in customers’ deposit accounts, as well as loans, mortgages and credit card accounts. Some of these banks have thousands of branches, while others are mostly, or exclusively, online. All of these banks are FDIC insured.

Based on asset size, here are the top 20 largest banks in the United States.

Frequently asked questions

Chase, part of JPMorgan Chase & Co., is the largest bank by asset size in the U.S, including deposits from checking and savings and other accounts, plus loans, mortgages, and more. It has $2.445 trillion in assets, according to the latest information from the Federal Reserve.

The five largest banks in the U.S., according to domestic assets, are Chase, Bank of America, Wells Fargo Bank, Citibank and U.S. Bank.

Generally, big, national banks serve more of the country than regional or community banks do. A regional bank might be limited to serving a few neighboring states; a community bank might serve only one city within a state.

National banks tend to have more technological resources and a wider variety of products than  smaller banks; on the other hand, smaller banks can offer more personalized service.

Some of the biggest banks in the U.S. (according to their assets) are also regional banks, serving a smaller area than big-name banks such as Chase and Bank of America. These banks may offer in-person services to a specific region as well as a robust menu of services and accounts online.

Your money is equally safe in any bank that's insured by the Federal Deposit Insurance Corp. As long as your bank has this protection, you're insured for up to $250,000 per person, per ownership category, per bank.

Similarly, your money is equally safe in any credit union that’s insured by the National Credit Union Administration. Credit unions that have this protection insure your money for up to $250,000 per person, per account, per credit union.
