What banks can do with your account
A bank can hold your money in an account, move it between accounts you own, send it to other people or businesses, and lend it out to other customers. They can also charge you fees, freeze your account if they suspect fraud, report your account activity to the government, and close your account if you break their rules. These are the core things banks do — and they're allowed to do them because you agree to their terms when you open an account.
When you deposit money, it becomes the bank's legal property, though you keep the right to withdraw it. The bank uses deposits from all customers to make loans, which is how they make money to pay you interest and cover their costs. This is why your money is insured by the Federal Deposit Insurance Corporation (FDIC) — if the bank fails, the government guarantees you'll get your money back up to $250,000 per account type per bank.
Key Takeaways
- Banks can hold, move, and lend your money, but they must follow federal rules about how they treat deposits and report suspicious activity.
- Your money is insured up to $250,000 per account type at each bank through FDIC insurance, so deposits are protected if the bank fails.
- Banks can freeze your account, charge fees, or close it, but they must give you notice and a chance to withdraw your money in most cases.
- Banks cannot take your money without your permission, use it for their own purposes, or share your account details with third parties without legal reason.
- If a bank violates its own rules or federal law, you can file a complaint with your state banking regulator or the Consumer Financial Protection Bureau.
What banks cannot do with your money
A bank cannot take money from your account without your permission, use your deposits for their personal business, or give your account information to someone else just because they ask. They also cannot charge you fees that aren't in your account agreement, discriminate against you based on race, religion, or other protected characteristics, or refuse to serve you without a legal reason.
If someone claims to be from your bank and asks for your password, account number, or Social Security number over the phone or email, that is not the bank — that is a scam. Real banks never ask for this information unsolicited. Banks also cannot require you to waive your right to sue them in court, though they can require you to use arbitration instead (which means a private judge decides disputes rather than a court).
When a bank can freeze or close your account
A bank can freeze your account — meaning you cannot withdraw money — if they suspect fraud, money laundering, or other illegal activity. They can also freeze it if you owe money to the bank itself, such as overdraft fees or a loan default. In most cases, the bank must tell you why and give you a chance to explain or withdraw your remaining money, though they may freeze first and notify you after if the situation is urgent.
Banks can close your account without your permission if you repeatedly overdraw it, bounce checks, or violate their terms of service. They must give you notice — usually 30 days — and let you withdraw any remaining balance. If you have direct deposit set up, you'll need to change it to a new account before the closure date so your paycheck doesn't bounce.
How banks report your activity to the government
Banks report large deposits and suspicious patterns to the Financial Crimes Enforcement Network (FinCEN), a federal agency that tracks money laundering and terrorism financing. If you deposit more than $10,000 in cash in a single day, the bank files a Currency Transaction Report. This is routine and legal — it doesn't mean you've done anything wrong.
Banks also file Suspicious Activity Reports (SARs) when they notice patterns that don't match your normal account use — for example, sudden large transfers to a country you've never sent money to, or frequent cash withdrawals that seem designed to avoid the $10,000 reporting threshold. These reports are confidential and go only to law enforcement, not to other banks or the public. You won't be notified that a SAR was filed.
Your rights if a bank makes a mistake
If a bank charges you a fee you didn't authorize, processes a transaction twice, or loses a deposit you made, you have the right to dispute it. For unauthorized transfers or errors, you must report them within 60 days of receiving your statement. The bank then has 10 business days to investigate and tell you what they found.
If the bank made an error, they must correct it and refund any fees or interest you lost. If they cannot find evidence of an error, they can keep the money, but they must explain their decision in writing. You can then file a complaint with your state's banking regulator or the Consumer Financial Protection Bureau (CFPB) if you believe the bank acted unfairly.
What happens if your bank fails
If your bank becomes insolvent and cannot pay back deposits, the FDIC steps in and pays you back up to $250,000 per account type. This means if you have a checking account with $150,000 and a savings account with $150,000 at the same bank, both are fully covered because they are different account types. If you have $300,000 in a single checking account, only $250,000 is insured.
Joint accounts (accounts you share with another person) are insured separately, so each owner's share up to $250,000 is covered. Money market accounts and CDs are also insured separately from checking and savings. The FDIC does not insure investment accounts, stocks, bonds, or money held in a safe deposit box — only deposits.
How to know if a bank is legitimate
Before you open an account, check whether the bank is FDIC-insured by searching the FDIC's Bank Find tool on their website. If a bank is not FDIC-insured, your deposits are not protected if the bank fails. Credit unions are insured by the National Credit Union Administration (NCUA) instead, which offers the same $250,000 protection.
Legitimate banks have a physical address, a customer service phone number you can verify independently, and a website with security features (look for "https://" and a lock icon in your browser). If you're unsure whether a bank is real, call the FDIC or NCUA directly — never use a phone number from an email or text message claiming to be from the bank.
Frequently Asked Questions
Can a bank take money from my account to pay a debt I owe them?
Yes, if you owe the bank money — such as overdraft fees, a loan default, or a bounced check — they can take it from your account without asking first. However, they must follow rules about which accounts they can take from and must notify you. Some accounts, like Social Security deposits, have special protections that limit what banks can take.
Can a bank see all my money if I have accounts at other banks?
No. Banks can only see accounts you hold with them. They cannot see your accounts at other banks, credit unions, or financial institutions. However, if you explore for a loan or credit card, the lender will pull your credit report, which shows accounts you've opened but not the balances or transactions.
What should I do if I think my bank is committing fraud?
Contact your state's banking regulator or file a complaint with the Consumer Financial Protection Bureau (CFPB) online. You can also report suspected fraud to the FBI's Internet Crime Complaint Center if it involves identity theft or scams. Keep copies of all statements and communications as evidence.
Can a bank refuse to open an account for me?
Banks can refuse to open an account if you have a history of overdrafts, bounced checks, or fraud at other banks — they check a system called ChexSystems. They cannot refuse based on race, religion, national origin, or other protected characteristics. If you're refused, ask why and request a copy of your ChexSystems report to check for errors.
Is my money safe if I keep it in cash at home instead of a bank?
Cash at home is not insured if it's lost, stolen, or destroyed. A bank account gives you FDIC protection up to $250,000 and a record of your money. For amounts over $250,000, you can open accounts at multiple banks or use different account types (checking, savings, money market) to increase your coverage.
