Yes, savings account interest rates change regularly, and your bank can lower yours without your permission

Interest rates on savings accounts are not locked in. Your bank can raise or lower the rate it pays you at any time, and most do so multiple times per year. The rate you see when you open an account is not a promise for life — it is the rate for that moment. Banks change rates in response to what the Federal Reserve does, what competing banks offer, and their own business decisions. You will not wake up to find your rate has doubled, but you might find it has dropped by half.

The most common trigger is a Federal Reserve rate change. When the Fed raises or lowers its benchmark interest rate, banks typically adjust what they pay depositors within days or weeks. When the Fed was raising rates aggressively from 2022 through 2023, savings account rates climbed from near zero to 4% or 5%. When the Fed paused and then began cutting rates in 2024, those same rates started falling. Your bank does not have to match the Fed move exactly — some banks move faster, some move slower, and some move in the opposite direction.

Key Takeaways

  • Banks can change your savings rate at any time without your permission, though they must notify you before the change takes effect.
  • Federal Reserve rate decisions trigger most savings rate changes within days or weeks, but the size and speed of your bank's response varies.
  • Online banks and high-yield savings accounts typically respond faster to Fed changes than traditional brick-and-mortar banks.
  • Checking your current rate against what new customers are offered can tell you whether your bank is paying you less than it should.
  • Moving your money to a different bank is free and takes a few days, so you are not locked in if your rate falls too far behind.

When banks raise rates and when they cut them

Banks raise rates when they need to attract deposits. This happens most visibly when the Federal Reserve is raising its own rates — banks know depositors have other options, so they compete by offering higher yields. During 2023, when the Fed was at its highest level in two decades, online banks and credit unions offered 4.5% to 5.35% on savings accounts. Traditional banks often lagged behind, offering 0.01% to 0.5% on the same products.

Banks cut rates when they have enough deposits or when the Fed is cutting. Once the Fed began lowering rates in September 2024, high-yield savings rates started dropping within weeks. Some banks cut aggressively; others held their rates steady for months to keep customers. The bank's strategy depends on how much deposit money it needs and how much it expects to earn from lending that money out.

Your bank will notify you before a rate change takes effect — usually by email, mail, or a notice in your online account. The timing varies: some banks give you 30 days' notice, others give you 10. Read these notices carefully, because they tell you the new rate and when it starts. If the cut is steep and you have options elsewhere, that notice is your signal to move.

How to learn about your rate has fallen behind

The easiest way is to check what your bank is currently offering to new customers. Go to your bank's website, look up the savings account product you own, and write down the rate shown. If new customers are getting 4.5% and you are earning 3.2%, your bank is paying you less than it is willing to pay strangers. This is common and deliberate — banks count on inertia to keep existing customers from noticing.

You can also compare your rate against what other banks are offering. Websites like Bankrate, DepositAccounts, and the FDIC's National Rates and Rate Caps table show current rates across hundreds of banks. Spend 10 minutes scanning these sites to see what the market rate is for a savings account in your region or for online banks nationally. If you are earning 0.5% and online banks are offering 4.3%, you are leaving money on the table.

The difference adds up fast. On a $10,000 balance, the gap between 0.5% and 4.3% is about $380 per year in lost interest. On $50,000, it is $1,900 per year. That is real money, and it is yours to claim by moving to a bank that is paying the current rate.

Why online banks and credit unions move faster than traditional banks

Online banks have lower overhead costs and fewer customers to manage, so they can adjust rates quickly and offer higher yields. When the Fed raises rates, online banks often raise their savings rates within days. Traditional banks with physical branches have higher costs and often move more slowly — they may wait weeks or months, betting that most customers will not notice or will not bother to switch.

Credit unions also tend to move faster than big banks, because they are member-owned and often prioritize paying competitive rates to retain deposits. If you have access to a credit union, check what they are offering. Credit union savings accounts are insured the same way bank accounts are — up to $250,000 per account holder, per institution, through the NCUA (the credit union equivalent of the FDIC).

What happens to your money when rates drop

Your existing balance does not disappear or shrink. The rate drop only affects the interest you earn going forward. If you have $10,000 in a savings account earning 4% and the rate drops to 2%, you still have $10,000. You will earn less interest each month, but your principal is untouched. The drop feels like a loss because you were counting on that higher interest, but it is not a loss of money you already had.

This is different from a CD (certificate of deposit), where your rate is locked in for the term. If you open a one-year CD at 4.5%, that rate does not change for 12 months, even if the Fed cuts rates to 1%. Savings accounts have no such lock-in — the tradeoff for flexibility is that rates can move against you.

Moving your money to a higher-rate bank

If your bank cuts rates and you find a better option elsewhere, switching is free and takes three to five business days. You do not need your bank's permission to leave, and you will not pay a penalty. Here is the basic process: open a new savings account at the bank offering the higher rate, then transfer your money from the old account to the new one. You can do this online through an ACH transfer, or you can withdraw cash and deposit it at the new bank.

Some banks offer a "transfer service" where you give them the login credentials for your old account and they pull the money for you. This is convenient but optional — you can always do it yourself. Once the transfer clears, close the old account if you want to. There is no rush; you can keep both accounts open for a while if you are unsure.

The only real cost is the time it takes to set up the new account and move the money. If you are moving $50,000 and the rate difference is 3%, that move will earn you an extra $1,500 per year. Spending 30 minutes to set it up is a good trade.

Rates on money market accounts and other savings products

Money market accounts, high-yield savings accounts, and regular savings accounts all have variable rates that change the same way. The rate you see today is not the rate you will see in six months. Money market accounts sometimes offer a tiered rate structure, where you earn a higher rate if your balance is above a certain threshold — but those tiers can change too.

CDs are the exception. When you buy a CD, the rate is fixed for the entire term — three months, six months, one year, five years, whatever you choose. You cannot withdraw the money early without paying a penalty (usually a few months of interest). The tradeoff is certainty: you know exactly what you will earn, and the bank cannot cut your rate.

If you want to lock in a rate before the Fed cuts again, a CD is the tool. If you want flexibility and do not mind that rates can move, a savings account or money market account is fine — just check your rate every few months and be ready to move if it falls too far behind.

Frequently Asked Questions

Can my bank lower my rate without telling me?

No. Banks must notify you before a rate change takes effect, usually by email or mail. The notice period varies by bank and state, but is typically 10 to 30 days. Read these notices carefully — they tell you the new rate and when it starts. If you miss the notice, you may not realize your rate has dropped until you check your account.

If I move my money to a new bank, will I lose the interest I already earned?

No. Interest you have already earned is yours to keep. When you transfer your balance to a new bank, you take that interest with you as part of your principal. Only future interest is affected by the rate change. The old bank will not claw back interest you already received.

Do savings rates ever go up without the Fed raising rates?

Yes, but rarely. A bank might raise its rate to attract deposits during a period of strong loan demand, or to compete with a rival bank offering a promotional rate. These moves are smaller and less common than Fed-driven changes. Most big rate moves follow Federal Reserve decisions.

What is the difference between APY and the interest rate on my savings account?

APY (annual percentage yield) is the rate you see advertised — it includes the effect of compounding, so it is slightly higher than the base interest rate. For savings accounts, the difference is small. What matters is that the APY is what you will actually earn over a year if you leave the money untouched. That is the number to compare between banks.

If rates keep falling, should I move my money to a CD?

A CD locks in your rate for a set term, so if you believe rates will fall further, a CD protects you from that drop. The tradeoff is that you cannot access the money without paying a penalty. If you might need the money within the next year or two, a savings account is more flexible. If you are confident you will not touch it, a CD at today's rate is a reasonable way to protect yourself from future cuts.
