Commercial banks are the most common type of bank you use for everyday checking and savings accounts

A commercial bank is a bank that takes deposits from individuals and businesses, then lends that money out to other customers and businesses. They make money on the difference between what they pay you in interest on your savings and what they charge borrowers on loans. Unlike investment banks or credit unions, commercial banks focus on standard deposit accounts and lending products that ordinary people and small to medium-sized businesses need.

When you open a checking account at a bank with branches in your town, you are almost certainly using a commercial bank. The bank holds your money, processes your payments, and offers you a debit card. That same bank is also lending money to someone else buying a house or a business buying equipment. This dual role — taking deposits and making loans — is what defines a commercial bank.

Key Takeaways

  • Commercial banks accept deposits from individuals and businesses, then lend that money to other borrowers, making profit on the interest spread.
  • Common examples include Chase, Bank of America, Wells Fargo, Citibank, and regional banks like PNC or U.S. Bank that operate branches in your area.
  • Commercial banks differ from credit unions (member-owned, non-profit) and investment banks (which trade securities and handle large corporate deals).
  • Your deposits at a commercial bank are insured up to $250,000 per account type by the FDIC, a federal agency that protects depositors if the bank fails.

Major national commercial banks you likely know by name

Chase (officially JPMorgan Chase) is the largest commercial bank in the United States by assets. It operates thousands of branches and ATMs nationwide and offers checking, savings, money market accounts, and personal loans. Chase also owns several subsidiary brands like Chase Bank USA and Sapphire Banking.

Bank of America is the second-largest commercial bank and operates in all 50 states. It provides standard deposit accounts, credit cards, auto loans, and mortgages. Bank of America also owns Merrill Lynch, though that division handles investment services separately from the commercial banking side.

Wells Fargo operates thousands of branches and is known for checking and savings accounts, home loans, and auto financing. Citibank (part of Citigroup) offers deposit accounts and personal lending products, though it has fewer physical branches than the others and emphasizes online banking.

U.S. Bank, PNC Bank, Truist, and KeyBank are large regional commercial banks that operate in multiple states but not nationwide. They offer the same core products — checking, savings, loans — but may have stronger presence in certain regions. Many people choose regional banks because they have local branch staff and may offer better rates on savings accounts or lower fees.

How commercial banks differ from credit unions

A credit union is a member-owned, non-profit financial institution. You must be a member to open an account, and membership is often tied to your employer, your union, your school, or your geographic location. Credit unions do not have shareholders demanding profit; instead, they return earnings to members through higher savings rates or lower loan rates.

Commercial banks are for-profit corporations owned by shareholders. They aim to maximize profit, which means they may charge higher fees and offer lower interest on savings. However, commercial banks have more branches and ATMs, more online tools, and faster loan decisions because they have larger staffs and more capital to lend.

Both commercial banks and credit unions are insured by federal agencies — commercial banks by the FDIC, credit unions by the NCUA (National Credit Union Administration). Both protect your deposits up to $250,000 per account type if the institution fails.

How commercial banks differ from investment banks

An investment bank does not take deposits from regular customers. Instead, it handles large financial transactions for corporations and wealthy individuals — underwriting stock offerings, managing mergers and acquisitions, and trading securities. Investment banks employ traders, analysts, and deal specialists, not tellers and loan officers.

Some large financial companies own both a commercial bank and an investment bank under the same parent company. JPMorgan Chase owns both Chase Bank (commercial) and JPMorgan (investment banking). Bank of America owns both Bank of America (commercial) and Bank of America Securities (investment). The two divisions operate separately and serve different customers, though they share the same parent company name.

If you have a regular checking account and take out a personal loan, you are dealing with the commercial bank side. If you are a corporation raising money by selling stock, you are dealing with the investment bank side.

Types of accounts and services commercial banks offer

Commercial banks offer checking accounts for everyday spending, with a debit card and online bill pay. They offer savings accounts that earn interest, though the rate varies by bank and account type. Money market accounts combine features of checking and savings — they earn higher interest but limit how many withdrawals you can make per month.

Most commercial banks also offer certificates of deposit (CDs), which lock your money away for a set term (3 months to 5 years) in exchange for a may provide interest rate. They offer personal loans for debt consolidation, home improvement, or other expenses. They offer auto loans and mortgages for home purchases.

Larger commercial banks offer business checking and savings accounts for small businesses and corporations, along with merchant services (payment processing), payroll services, and lines of credit. Some offer wealth management services for customers with significant assets, though this may be handled by a separate division.

FDIC insurance protects your money at commercial banks

The Federal Deposit Insurance Corporation (FDIC) insures deposits at commercial banks. If a bank fails, the FDIC pays depositors up to $250,000 per account type per bank. This means if you have $300,000 in a checking account at Chase and Chase fails, the FDIC pays you $250,000 and you lose $50,000.

However, if you have $250,000 in a checking account and $250,000 in a savings account at the same bank, both are fully insured because they are different account types. If you have $250,000 in a checking account at Chase and $250,000 in a checking account at Bank of America, both are fully insured because they are at different banks.

Joint accounts (accounts held by two or more people) are insured separately. If you and your spouse have a joint checking account with $500,000, the FDIC insures up to $250,000 of that account. Retirement accounts (IRAs, 401(k)s) held at a commercial bank are also insured separately up to $250,000.

You do not need to do anything to get FDIC insurance — it is automatic at any bank that displays the FDIC logo or states it is FDIC-insured. You can verify a bank's FDIC status on the FDIC website by searching for the bank's name.

How to choose a commercial bank for your needs

If you need frequent in-person service, choose a bank with branches near your home or workplace. National banks like Chase and Bank of America have thousands of branches; regional banks have fewer but may offer better personal service. If you rarely visit a branch, an online-only commercial bank may offer higher savings rates because it has lower overhead costs.

Compare monthly fees, minimum balance requirements, and interest rates on savings accounts. Some banks charge $10 to $15 per month for checking if you do not maintain a minimum balance; others waive fees if you set up direct deposit. Savings account rates vary widely — some banks offer 0.01% while others offer 4% or higher, depending on market conditions and the bank's strategy.

Check whether the bank's ATM network works for you. If you travel frequently or live in multiple places, a bank with nationwide ATMs saves you money on out-of-network fees. Some banks reimburse out-of-network ATM fees; others charge $2 to $3 per transaction.

Frequently Asked Questions

What is the difference between a commercial bank and a savings bank?

A savings bank historically focused on taking deposits and making home loans, while a commercial bank made business loans. Today, the distinction is blurred — most large banks do both. The terms are often used interchangeably, though some smaller institutions still specialize in one or the other.

Can I have accounts at multiple commercial banks?

Yes. You can open accounts at Chase, Bank of America, and a credit union all at the same time. Each deposit is insured separately by the FDIC or NCUA up to $250,000 per account type. Some people maintain accounts at multiple banks to diversify their deposits or to take advantage of different interest rates and fee structures.

Do commercial banks offer investment services?

Most large commercial banks own investment divisions or partner with investment firms. You can often buy stocks, bonds, and mutual funds through your bank's website or by speaking to a financial advisor. However, the investment side is usually separate from the commercial banking side, and investment products are not FDIC-insured.

What happens to my money if a commercial bank fails?

The FDIC takes over the bank and pays depositors up to $250,000 per account type. Usually, another bank buys the failed bank's deposits and accounts, so you can access your money within a few days. You do not lose money as long as your balance is within the $250,000 limit per account type.

Are online commercial banks as safe as banks with physical branches?

Yes, as long as the online bank is FDIC-insured. Online banks have lower overhead, so they often offer higher interest rates on savings. The FDIC insurance is the same whether the bank has branches or operates only online. Check the bank's FDIC status before opening an account.
