What commercial banks are and what they do

A commercial bank is a bank that takes deposits from regular people and businesses, lends that money out, and charges fees for services. The word "commercial" just means they do business with the public — not that they only serve large companies. Most banks you've heard of are commercial banks.

When you put money in a checking or savings account, you're banking at a commercial bank. That bank uses deposits like yours to lend money to other customers for mortgages, car loans, and business loans. The bank keeps the difference between what it pays you in interest and what it charges borrowers. That's how they make money and pay their staff.

Commercial banks are regulated by federal and state authorities to make sure they don't take too much risk with your money. The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 per account holder per bank, so if the bank fails, you don't lose your money.

Key Takeaways

  • Commercial banks are the everyday banks where most people have checking and savings accounts, and they make money by taking deposits and making loans.
  • Large national banks like Bank of America, Chase, and Wells Fargo operate thousands of branches across the country and offer many services.
  • Regional banks like PNC Bank and U.S. Bank serve specific areas and often have lower fees or more personal service than national giants.
  • Community banks and credit unions are smaller, locally-owned institutions that may offer better rates or more flexibility for people new to banking.
  • All deposits at FDIC-insured commercial banks are protected up to $250,000, regardless of the bank's size.

Large national commercial banks

The biggest commercial banks operate branches in nearly every state and serve millions of customers. JPMorgan Chase is the largest by assets in the United States. Bank of America, Wells Fargo, and Citibank are also among the largest. These banks offer checking accounts, savings accounts, credit cards, mortgages, auto loans, and investment services all under one roof.

National banks have advantages and trade-offs. You can walk into a branch almost anywhere, use ATMs without fees at thousands of locations, and move money between accounts when ready online. But they often charge monthly maintenance fees on checking accounts, require higher minimum balances, and may have less flexibility if you're new to banking or have an unusual situation.

These banks also tend to have more automated customer service — you may spend time on hold or navigating phone menus rather than talking to someone who knows your account history. However, they invest heavily in security and fraud protection because they handle so much money.

Regional commercial banks

PNC Bank, U.S. Bank, Truist, and KeyBank are examples of regional commercial banks. They operate in multiple states but not nationwide, which means they know their local markets better than national giants do. A regional bank might have 500 to 1,500 branches instead of 4,000.

Regional banks often sit in the middle ground: larger than a community bank but smaller and more local than Chase or Bank of America. They typically offer the same products — checking, savings, loans, credit cards — but may have lower fees or be more willing to work with customers who don't fit a standard profile. Some regional banks are known for better customer service because branch staff have more authority to make decisions.

The trade-off is that you may have fewer ATM locations and less ability to bank in other states. If you move, you might need to switch banks or deal with out-of-state fees.

Community banks and local commercial banks

A community bank is a commercial bank that operates in one city, county, or small region — usually with fewer than 50 branches. Examples include local banks like Mechanics Bank in California, Umpqua Bank in the Pacific Northwest, and thousands of smaller institutions across the country. These banks are often owned locally or by a regional holding company rather than a national corporation.

Community banks often have lower fees, higher interest rates on savings accounts, and loan officers who know their customers by name. They may be more willing to work with people who are new to banking, have no credit history, or have had past banking problems. Because they lend locally, they understand the community's needs better than a national bank does.

The downside is fewer branches and ATMs, less online technology (though this is improving), and sometimes less security infrastructure than a national bank. However, community banks are still FDIC-insured, so your deposits are protected the same way.

Credit unions as an alternative to commercial banks

A credit union is not technically a commercial bank — it's a member-owned financial cooperative. But it offers many of the same services: checking accounts, savings accounts, loans, and credit cards. Examples include Navy Federal Credit Union, State Employees' Credit Union, and thousands of smaller credit unions tied to employers, professions, or geographic areas.

Credit unions often have lower fees and better interest rates than commercial banks because they're non-profit and return earnings to members rather than shareholders. They may also be more flexible with lending — a credit union might approve a loan for someone with limited credit history when a commercial bank would decline.

To join a credit union, you usually need to meet a membership requirement: work for a certain employer, live in a certain area, belong to a certain profession, or have a family member who is already a member. Credit union deposits are insured by the National Credit Union Administration (NCUA), which works the same way as FDIC insurance.

Online-only commercial banks

Ally Bank, Charles Schwab Bank, and Discover Bank are commercial banks with no physical branches — you do everything online or by phone. These banks typically offer higher interest rates on savings accounts and lower fees because they don't pay for buildings and staff in every city.

Online banks work well if you're comfortable managing money through an app or website and don't need to deposit cash or checks in person. Many online banks partner with ATM networks so you can withdraw cash without fees. However, if you need to talk to someone in person or deposit cash regularly, an online bank may not be the right fit.

Online banks are still FDIC-insured and regulated the same way as brick-and-mortar banks. The main difference is convenience and cost, not safety.

How to choose which type of commercial bank is right for you

Start by thinking about how you actually use a bank. Do you need to deposit cash regularly? Do you travel or move often? Do you prefer talking to people or using apps? Do you want the lowest fees or the best interest rates? Your answers will point you toward a type of bank.

If you deposit cash often and like in-person service, a community bank or regional bank may suit you better than a national bank or online bank. If you move frequently or travel, a national bank's wide branch network is valuable. If you want the lowest fees and highest savings rates and you're comfortable online, an online bank or credit union might be best.

You can also have accounts at more than one bank. Many people keep a checking account at a national bank for convenience and a savings account at an online bank or credit union for better interest rates. There's no rule against it, and it can actually help you manage money better.

Frequently Asked Questions

Is my money safe at a smaller community bank compared to a big national bank?

Yes. All FDIC-insured banks — whether they're national giants or tiny community banks — protect your deposits the same way up to $250,000. A community bank's smaller size doesn't make it less safe. The FDIC backs the deposit, not the bank's size.

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

A commercial bank is a for-profit business owned by shareholders. A credit union is a non-profit cooperative owned by its members. Credit unions often have lower fees and better rates, but you may need to meet membership requirements to join. Both are insured and regulated.

Can I use an ATM from a different bank without paying a fee?

It depends on the bank and the ATM network. National banks usually have large ATM networks with no fees. Online banks and credit unions often partner with ATM networks to offer free withdrawals. Always ask before opening an account if ATM fees matter to you.

Do I need to use the same bank for checking and savings?

No. You can have a checking account at one bank and a savings account at another. Many people do this to get the best rates and features from each bank. Just keep track of which accounts are at which banks for tax and insurance purposes.

What happens if a commercial bank fails?

The FDIC takes over and makes sure depositors get their money back up to $250,000 per account. You don't lose your deposits. The FDIC has a process to either merge the failed bank with another bank or pay out accounts directly.
