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

The interest rate your bank pays you on savings is not locked in. Banks can raise or lower the rate they offer to new customers at any time, and they can also lower the rate paid to existing customers—often with only a few days' notice. The rate you see advertised today may not be the rate you earn next month. The rate you earned last year almost certainly is not the rate you earn now.

Your bank's rate moves because the Federal Reserve changes its benchmark interest rate, because your bank wants to attract or shed customers, or because market conditions shift. When rates fall—which happens during economic slowdowns—your bank's savings rate typically falls too. When rates rise, banks may raise what they pay you, but the timing and amount vary widely by bank.

Key Takeaways

  • Banks can lower the interest rate on your existing savings account with as little as a few days' written notice, and you have no contractual right to the old rate.
  • Rate changes usually follow Federal Reserve decisions, but banks set their own rates independently and may move faster or slower than competitors.
  • Online banks and credit unions often respond to rate changes more quickly than large brick-and-mortar banks, and sometimes offer higher rates.
  • You can switch banks or move money to a higher-paying account without penalty, though some banks require a minimum balance to earn the advertised rate.
  • The rate you see advertised is the rate new customers get; existing customers may earn a different rate unless your account terms may provide otherwise.

How the Federal Reserve affects what your bank pays you

The Federal Reserve sets a target range for the federal funds rate—the rate at which banks lend to each other overnight. This is not the rate you earn on savings, but it is the anchor that moves all other rates. When the Fed raises its target, banks have more incentive to pay higher rates on savings to attract deposits. When the Fed lowers its target, banks have less incentive to pay you more.

The lag between a Fed decision and a change to your account rate varies. Some online banks move within days. Large national banks often wait weeks or move in smaller increments. A bank might raise rates on new accounts when ready but leave existing customer rates unchanged for months, or vice versa. There is no rule requiring them to move at the same speed or by the same amount.

Why your bank might raise or lower your rate independent of the Fed

Banks also change rates based on how much deposit money they need. If a bank has excess deposits and does not need more customer money right now, it may lower rates to reduce what it pays out. If a bank needs deposits to fund loans, it may raise rates to attract new money. This happens even when the Fed has not moved.

Competition matters too. If a competitor launches a high-yield savings account at 4.5% and your bank is paying 2%, your bank may eventually raise its rate to keep customers from leaving. But "eventually" can mean months. Banks also use rate changes as a marketing tool: a bank might offer a promotional rate for new customers only, then lower it after a few months once the customer is locked in.

The difference between advertised rates and the rate you actually earn

The rate displayed on a bank's website is almost always the rate new customers receive. Existing customers may earn a lower rate, especially if they opened their account years ago. Some banks tier rates by balance—you might earn 4.0% on the first $25,000 and 3.5% on anything above that. Others offer the same rate to all balances.

A few accounts come with a rate may provide, usually in the account terms or disclosure document. These are rare and typically only appear in promotional accounts with a fixed term (like a 12-month promotional rate). Standard savings accounts have no may provide. Your bank can lower your rate with written notice, usually 7 to 30 days depending on the bank and your state.

How to learn about your rate has changed

Banks are required to notify you before lowering your rate, but the notification often arrives as a small notice in your statement or an email you might miss. Log into your account and check the current rate listed there, then compare it to what you earned last month. Your statement or account history should show the rate you earned during each statement period.

If you notice your rate has dropped and you did not receive notice, contact your bank's customer service. If you received notice but did not see it, ask them to resend it. Keep records of the rates you earn over time—screenshot your account page or save statements. This matters if you ever need to dispute a rate change or file a complaint with your state banking regulator.

When to move your money to a higher-paying account

If your current bank's rate has fallen significantly below what competitors offer, moving money is free and takes a few days. You can open a new account at another bank and transfer your balance without penalty. Some banks charge a fee if you close an account within a certain period (often 90 to 180 days), so check the terms before you move.

Online banks and credit unions often pay higher rates than large national banks because they have lower overhead costs. A credit union savings account might pay 4.75% while a major bank pays 1.5% on the same type of account. The tradeoff is that online banks have no physical branches and credit unions may have membership requirements. Both are insured the same way—up to $250,000 per account holder per institution by the FDIC or NCUA.

What happens to your rate during economic downturns

When the economy slows and the Fed cuts rates, savings rates fall across the board. During the 2020 pandemic, rates on high-yield savings accounts dropped from around 2.0% to under 0.5% within weeks. Rates stayed low for two years until the Fed began raising rates again in 2022. Your bank cannot protect you from this—it is a market-wide shift, not a bank-specific choice.

The only way to lock in a rate is to move money into a certificate of deposit (CD), which guarantees a fixed rate for a set term. If you open a 12-month CD at 4.5%, you earn 4.5% for the full 12 months even if rates fall. The tradeoff is that you cannot withdraw the money without a penalty, usually a loss of some or all of the interest earned.

Frequently Asked Questions

Can my bank lower my rate without telling me?

No. Banks must notify you in writing before lowering your rate, usually 7 to 30 days in advance depending on your state and the bank's terms. The notice may arrive as a statement insert or email. If you did not receive notice, contact your bank and ask them to provide it.

If I move my money to a new bank, will that rate stay the same?

No. The rate you earn at a new bank is the rate that bank currently offers, which can change just like your old bank's rate. You are not locked into the rate you see on the day you open the account. However, you can move again if rates fall and competitors offer better terms.

Why do online banks pay more than big banks?

Online banks have lower costs because they do not operate physical branches. They pass some of those savings to customers in the form of higher interest rates. Big banks have more branches and staff, which costs more money, so they often pay lower rates on savings to offset those expenses.

Does the Fed's interest rate directly set my savings rate?

No. The Fed sets a target range for the federal funds rate, which influences but does not determine your savings rate. Banks set their own rates independently. Some move quickly when the Fed changes; others lag behind. A bank might raise rates on new accounts but not on existing ones, or vice versa.

What is the best way to track rate changes?

Check your account online monthly and compare your current rate to what you earned the previous month. Save screenshots or statements showing the rate for each period. If you are shopping for a new account, compare rates across multiple banks on the same day, since rates change frequently and vary widely.
