Money market accounts can lose value, but not the way a stock portfolio does

A money market account will not suddenly drop 20% in a week. Your principal—the money you deposit—is protected by FDIC insurance up to $250,000 per account holder per bank. But you can still lose purchasing power, and in some cases lose actual dollars, depending on what happens with interest rates and how the account is structured.

The real risk is not that the bank will fail and take your money. The real risk is that your money sits in an account earning 0.01% interest while inflation runs at 3%, which means you are effectively losing 2.99% of your purchasing power each year. That is a slow leak, not a dramatic loss, but it is real.

Key Takeaways

  • FDIC insurance protects your principal up to $250,000, so the bank cannot take your money or go under and leave you with nothing.
  • If interest rates fall after you open the account, the bank can lower your rate, and you earn less than you could have locked in elsewhere.
  • Inflation erodes purchasing power: if your account earns 1% but inflation is 3%, you lose 2% in real value each year.
  • Some money market accounts charge monthly fees that eat into your balance, though fee-free accounts are common.
  • A money market account is safer than stocks but riskier than a high-yield savings account in terms of rate stability and access to your money.

How FDIC insurance protects your principal

The Federal Deposit Insurance Corporation guarantees that if your bank fails, you get your money back up to $250,000. This is not a promise from the bank—it is a federal may provide. The FDIC maintains a fund paid for by bank premiums, and it has never failed to pay out a covered deposit.

This means you cannot lose your principal due to bank failure. You also cannot lose it because the bank made bad loans or bad investments. The money you put in stays there, insured, unless you withdraw it yourself.

The catch: this protection covers the account holder at one bank. If you have $250,000 at Bank A and $250,000 at Bank B, both are fully covered. If you have $500,000 at the same bank in the same account type, only $250,000 is covered. Money market accounts at the same bank are grouped together for insurance purposes, so multiple money market accounts at one bank do not multiply your coverage.

Interest rate risk: when rates fall and your earnings shrink

When you open a money market account, the bank tells you the current interest rate. That rate is not locked in. The bank can change it at any time, and usually does when the Federal Reserve changes its benchmark rate.

If you opened an account earning 4.5% in 2023 and the Fed began cutting rates in 2024, your bank likely lowered your rate to 4.0%, then 3.5%, and so on. You did not lose the money you had deposited, but you lost the income you expected to earn. That is a real loss of future earnings, not a loss of principal.

The opposite can also happen: if rates rise, your bank may not raise your rate as quickly as competitors do. You stay locked into a lower rate while new accounts at other banks earn more. This is not a loss of money, but it is a loss of opportunity.

Inflation erodes the value of what you hold

If your money market account earns 1% per year and inflation is 3% per year, you are losing 2% in purchasing power. Your account balance shows $10,000, but that $10,000 buys less than it did a year ago.

This is not a loss you see on a statement. The bank is not taking money out. But when you go to spend it, you can buy less with it than before. Over five years at 1% earnings and 3% inflation, $10,000 loses roughly 10% of its real value.

Money market accounts are particularly vulnerable to this because their rates are variable and often lag inflation. During periods of high inflation, money market rates may not keep pace, especially if you do not move your money to a higher-paying account.

Fees that reduce your balance

Some money market accounts charge monthly maintenance fees, early withdrawal penalties, or minimum balance fees. These fees come directly out of your account balance and reduce what you have.

A $10 monthly fee on a $5,000 account earning 0.5% interest means the fee eats up most of your earnings. Over a year, that is $120 gone. Many banks now offer money market accounts with no monthly fee, so paying one is usually a choice, not a requirement.

Read the fee schedule before opening an account. Look for accounts with no monthly maintenance fee, no minimum balance requirement, and no penalty for transfers or withdrawals (or at least understand what the penalty is and when it applies).

Withdrawal restrictions that lock your money in place

Money market accounts are hybrid products: they work like savings accounts but are named after money market funds. Some banks impose limits on how many withdrawals you can make per month, usually six. If you need to withdraw more than that, the bank may charge a fee or close the account.

This is not a loss of money, but it is a loss of access. If you need your cash and cannot get it without a penalty, you are paying to access your own money. This makes money market accounts less liquid than regular savings accounts, which typically have no withdrawal limits.

Before opening an account, confirm the withdrawal policy. Some banks have removed these limits entirely, while others still enforce them. If you think you might need frequent access to the money, a high-yield savings account may be a better fit.

Money market accounts versus other places to keep cash

A money market account is safer than a brokerage account holding stocks or bonds, because your principal is FDIC-insured and you are not exposed to market swings. But it is less safe than a high-yield savings account in one specific way: the rate is more likely to drop if interest rates fall, and the account may have withdrawal limits.

A high-yield savings account typically has no withdrawal limits and the same FDIC protection. The trade-off is that money market accounts sometimes offer slightly higher rates, though that gap has narrowed in recent years.

A certificate of deposit (CD) locks in a rate for a set term—six months, one year, five years. If rates fall, your rate does not. But you cannot access the money without a penalty. A money market account gives you flexibility; a CD gives you rate certainty.

Frequently Asked Questions

Can a money market account go negative?

No. Your account cannot go below zero unless you overdraft it, and most money market accounts do not allow overdrafts. If you withdraw all your money, the balance is zero. You cannot owe the bank money just by holding the account.

What if the bank goes out of business?

The FDIC takes over and pays you up to $250,000 within a few days. This has happened dozens of times in U.S. history, and every depositor with a covered balance has been paid in full. Your money is not at risk due to bank failure.

Is a money market account safe during a recession?

Yes, for your principal. Recessions do not cause bank failures automatically, and FDIC insurance protects you if one does. Your concern should be interest rate risk: during a recession, the Fed usually cuts rates, so your money market rate will fall and you will earn less.

Should I move my money if rates drop?

You can, and often should. If your current bank drops your rate to 1% and another bank offers 4%, moving the money costs nothing and takes a few days. There is no penalty for switching banks. The only reason not to move is if the difference is small and the hassle feels not worth it.

Can I lose money to fraud or theft?

If someone steals your login credentials and drains the account, the bank's fraud protection should cover it. Report it when ready. FDIC insurance does not cover fraud, but bank fraud policies do. If the bank fails to reimburse you, contact your state banking regulator.
