A commercial bank is a for-profit institution that takes deposits from individuals and businesses, lends that money out, and charges fees for services

The banks most people use every day—Chase, Bank of America, Wells Fargo, your local credit union's larger cousin—are commercial banks. They're different from investment banks, which trade securities and manage large portfolios, and from central banks like the Federal Reserve, which regulate the money supply. A commercial bank's core job is straightforward: hold your money safely, let you withdraw it when you need it, lend portions of it to borrowers at a higher interest rate than they pay you, and keep the difference as profit.

When you open a checking or savings account at a commercial bank, you're depositing money that the bank then uses. The bank pays you a small amount of interest on savings accounts (often less than 1 percent annually, though this varies). That same bank lends your deposit—combined with deposits from thousands of other customers—to someone buying a house or a business buying equipment. The borrower pays interest on that loan. The bank keeps the spread between what it pays depositors and what it collects from borrowers, minus operating costs.

Key Takeaways

  • Commercial banks make money by taking deposits, paying depositors a small interest rate, and lending that money at a higher rate to borrowers.
  • Common examples include Chase, Bank of America, Wells Fargo, and thousands of smaller regional and community banks across the United States.
  • Commercial banks offer checking accounts, savings accounts, loans, credit cards, and other financial services to individuals and businesses.
  • The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 per account holder per bank, protecting your money if the bank fails.
  • Commercial banks are regulated by federal and state authorities to may support they maintain enough capital and don't take excessive risks with customer deposits.

How commercial banks differ from other financial institutions

Credit unions operate similarly to commercial banks but are nonprofit organizations owned by their members rather than shareholders. A credit union takes deposits and makes loans, but any profit goes back to members as lower fees or higher interest rates on savings. Credit unions are smaller and often serve a specific group—employees of a company, members of a profession, or people in a geographic area.

Online banks like Ally, Marcus, and Discover are commercial banks too, but they have no physical branches. They typically offer higher interest rates on savings accounts because they have lower overhead costs. Investment banks like Goldman Sachs or Morgan Stanley focus on trading securities, managing investment portfolios, and advising on mergers rather than taking deposits from ordinary customers.

Savings and loan institutions (also called thrifts) historically focused on mortgage lending and savings accounts but now operate much like commercial banks. The distinction between a savings and loan and a commercial bank has blurred significantly over the past few decades.

What services commercial banks provide

Beyond deposits and loans, commercial banks offer checking accounts with debit cards, savings accounts, money market accounts, certificates of deposit (CDs), credit cards, home mortgages, auto loans, business loans, wire transfers, and safe deposit boxes. Larger commercial banks also offer investment services, wealth management, and business banking products like merchant processing and payroll services.

The range of services depends on the bank's size and focus. A large national bank like JPMorgan Chase offers nearly everything. A community bank might focus on checking, savings, and local mortgages. An online bank might offer only deposits and a limited loan menu.

How the FDIC protects your deposits at commercial banks

The Federal Deposit Insurance Corporation (FDIC) insures deposits at most commercial banks up to $250,000 per depositor per bank. This means if the bank fails, the FDIC will reimburse you for deposits up to that limit. The coverage applies separately to different account types at the same bank—your checking account, savings account, and CD are each insured up to $250,000.

Not all financial institutions carry FDIC insurance. Credit unions are insured by the National Credit Union Administration (NCUA) instead, with the same $250,000 limit. Investment firms and brokerages are not FDIC-insured; they carry Securities Investor Protection Corporation (SIPC) coverage, which protects against loss of securities and cash held for investment purposes, not deposits.

You can verify that a bank is FDIC-insured by searching the FDIC's Bank Find tool on their website or asking the bank directly. If a bank is not FDIC-insured, your deposits have no federal protection if the institution fails.

How commercial banks are regulated

Commercial banks operate under federal and state oversight. The Office of the Comptroller of the Currency (OCC) regulates nationally chartered banks. State banking authorities regulate state-chartered banks. The Federal Reserve oversees larger banks and sets monetary policy. The Consumer Financial Protection Bureau (CFPB) enforces consumer protection laws and investigates complaints about unfair or deceptive practices.

Banks must maintain a minimum amount of capital relative to their assets, undergo regular audits, and submit to stress tests that simulate economic downturns. These rules exist to prevent banks from taking excessive risks with customer deposits and to may support they can survive financial shocks.

Examples of major commercial banks in the United States

The largest commercial banks by assets are JPMorgan Chase, Bank of America, Wells Fargo, Citigroup, and U.S. Bancorp. These institutions operate thousands of branches nationwide and serve millions of customers. Each offers a full range of banking services.

Regional banks like PNC, Truist, KeyBank, and Huntington Bancshares serve multiple states but are smaller than the "Big Five." Community banks—institutions with assets under $10 billion—operate in specific regions or cities. Examples include Umpqua Bank in the Pacific Northwest, Cullen/Frost Bankers in Texas, and countless local institutions. Online commercial banks like Ally, Marcus (owned by Goldman Sachs), and Discover offer deposit accounts and loans without physical branches.

All of these are commercial banks because they take deposits from the public and make loans. The difference is scale, geography, and service breadth.

Why commercial banks matter to your finances

Your choice of commercial bank affects the fees you pay, the interest you earn on savings, the rates you get on loans, and the convenience of accessing your money. Banks with many branches and ATMs offer more physical access. Online banks often offer higher interest rates but require you to manage accounts digitally. Local community banks may offer more personalized service but fewer services overall.

Understanding how commercial banks work helps you evaluate which one fits your needs. If you keep a large balance in savings, a bank offering higher interest rates matters more. If you need frequent in-person service, branch availability matters more. If you borrow regularly, loan rates and terms matter more.

Frequently Asked Questions

Is my money safe in a commercial bank?

Your deposits are safe up to $250,000 per account type at FDIC-insured banks. The FDIC has protected deposits since 1933, and no depositor has lost money on insured deposits during a bank failure. Verify the bank is FDIC-insured before opening an account by checking the FDIC's Bank Find tool.

What's the difference between a commercial bank and a credit union?

Commercial banks are for-profit institutions owned by shareholders. Credit unions are nonprofit organizations owned by members. Both take deposits and make loans, but credit unions typically offer lower fees and higher savings rates because profits return to members. Credit unions are insured by the NCUA instead of the FDIC, with the same $250,000 coverage limit.

Can I use any commercial bank's ATM?

Most commercial banks participate in ATM networks that let you withdraw cash at other banks' ATMs, though you may pay a fee ($1 to $3 typically). Some banks reimburse out-of-network ATM fees. Online banks often reimburse ATM fees nationwide. Ask your bank about its ATM policy before opening an account if ATM access matters to you.

Do commercial banks pay interest on checking accounts?

Most commercial banks pay little or no interest on checking accounts. Savings accounts, money market accounts, and CDs pay interest, though rates vary widely. Online banks typically offer higher interest rates on savings products than brick-and-mortar banks because their costs are lower.

What happens if a commercial bank fails?

The FDIC takes over the bank, protects insured deposits up to $250,000, and usually arranges for another bank to assume the failed bank's deposits and branches. Your money remains accessible, though the transition may take a few days. Deposits over $250,000 are not protected and may result in partial loss.
