Interest rates directly change how much money your bank pays you on savings

When the Federal Reserve raises or lowers interest rates, your savings account's earnings move in the same direction—usually within weeks. A higher Fed rate means banks have more incentive to pay you more to keep your money with them. A lower Fed rate means they pay you less. The connection is not automatic or when ready, but it is direct and measurable.

Your bank does not have to match the Fed rate exactly. Banks set their own rates based on what they think will keep customers and what they can afford to pay. But when the Fed moves, most banks follow within 30 to 90 days. Some move faster; some move slower. The size of the move also varies—a bank might pass along 75% of a Fed increase but only 50% of a decrease.

This matters because the difference between a 0.01% annual percentage yield (APY) and a 4.50% APY on a $10,000 balance is roughly $450 per year. Over time, that gap compounds. If you keep the same money in the same account for five years at different rate environments, the total you earn can differ by thousands of dollars.

Key Takeaways

  • When the Federal Reserve raises rates, banks typically increase savings account APY within 30 to 90 days, though the exact amount varies by bank.
  • When the Federal Reserve lowers rates, banks usually cut savings account APY faster than they raised it, sometimes within weeks.
  • High-yield savings accounts at online banks tend to move with Fed changes more quickly and completely than traditional bank savings accounts.
  • Your existing savings account rate is locked in only while you hold that account; switching banks or account types is how you capture a higher rate when the Fed moves up.

Why banks change rates when the Fed moves

The Federal Reserve does not set the rate your bank pays you. It sets the federal funds rate, which is the rate banks charge each other to borrow overnight. When that rate goes up, banks' costs rise. When it goes down, their costs fall. Banks adjust what they pay depositors based on these changing costs and on what competitors are offering.

A bank's decision to raise or lower your savings rate is also a competitive move. If one bank raises its APY to 4.50% and yours stays at 0.01%, you have a reason to move your money. Banks know this, so they watch what competitors are doing and adjust to keep customers from leaving. During periods when the Fed is raising rates, this competition can work in your favor—banks race to offer higher rates to attract deposits.

During periods when the Fed is cutting rates, the opposite happens. Banks lower rates faster and more aggressively because they are trying to reduce what they pay out. A bank might cut your rate by 0.50% within two weeks of a Fed cut, but take three months to raise it by 0.25% after a Fed increase. This asymmetry is normal and frustrating, but it is how the system works.

How quickly your rate changes depends on your bank type

Online banks and online-only divisions of larger banks usually move fastest. They have lower overhead, they compete primarily on rate, and they can change rates with a few clicks. When the Fed raises rates, online banks often increase their APY within one to two weeks. When the Fed cuts, they cut within days. Examples include banks like Marcus, Ally, and American Express Personal Savings, though the specific timing and amount varies.

Traditional brick-and-mortar banks move more slowly. They have more customers, more branches, and more systems to update. A rate change might take 60 to 90 days to roll out. Some large banks also have less incentive to compete on rate because they have stable deposit bases and can afford to pay less. If you have a savings account at a major national bank, you may see your rate lag behind the Fed by several months.

Credit unions vary widely. Some move quickly; some move slowly. It depends on the credit union's size, its deposit needs, and its board's strategy. If you belong to a credit union, calling and asking when they plan to adjust rates can give you a clearer picture than guessing.

What happens to your rate when you already have an account

If you opened a savings account at a specific rate, that rate is not locked in. Your bank can change it at any time, and they will notify you before they do—usually by email or mail, sometimes through your online banking portal. The notification typically comes 30 days before the change takes effect, though the exact timing varies by bank and by state.

You have no obligation to accept the new rate. If your bank lowers your rate and you do not like it, you can move your money to another bank that is offering more. This is the main reason to shop around when rates change. If the Fed has just raised rates and your current bank has not moved yet, moving to a competitor offering a higher rate is often the fastest way to capture the increase.

Some banks offer tiered rates based on balance size—higher balances earn higher rates. When the Fed moves, these tiers usually all shift up or down together, but by different amounts. Check your account terms to understand how your specific balance tier is affected.

The difference between Fed rate changes and what you actually earn

The Federal Reserve's rate and your savings account's APY are not the same thing. The Fed rate is a wholesale rate between banks. Your APY is what your bank chooses to pay you. The Fed might raise its rate by 0.75%, but your bank might raise your APY by only 0.50% or 0.60%. The gap is the bank's margin—the profit they keep.

During competitive periods, margins shrink. When the Fed was raising rates from 2022 to 2023, online banks offered rates very close to the Fed rate because they were competing hard for deposits. Margins were thin. During periods when the Fed is cutting rates or holding them steady, margins widen. Banks cut customer rates more than the Fed cut, keeping the difference.

You can track this by watching the Fed rate and comparing it to what banks are advertising. If the Fed rate is 5.25% and the highest advertised savings rate is 4.75%, the gap is roughly 0.50%. That gap tells you how much margin banks are keeping in the current environment.

How to position yourself when rates are changing

If the Fed is raising rates, move your money to a bank offering the highest current rate. Do not wait for your current bank to catch up—they may move slowly, and you lose earnings in the meantime. Online banks and online-only accounts almost always lead the way. Moving takes one to three business days, and you can move money back if you change your mind.

If the Fed is cutting rates, the situation is less urgent. Rates will fall across the board, so moving to a different bank will not protect you from the decline. What you can do is lock in a higher rate while it is available, knowing that all rates will eventually fall. Some people move to a longer-term certificate of deposit (CD) when they expect rates to drop, because CDs lock in a rate for a set period.

If the Fed is holding rates steady, shop around every few months. Banks adjust rates even when the Fed does not move, based on their own deposit needs and competitive pressures. You might find a better rate at a different bank even if nothing has changed at the Federal Reserve.

What happens to savings during high-rate and low-rate environments

In a high-rate environment (like 2023 and 2024, when savings rates reached 4% to 5%), your money grows noticeably. A $50,000 balance earning 4.50% APY generates roughly $2,250 per year in interest. That compounds—next year you earn interest on $52,250, not just $50,000. Over five years at that rate, you would earn more than $12,000 in interest alone.

In a low-rate environment (like 2010 to 2021, when rates were near 0%), your money barely grows. A $50,000 balance earning 0.01% APY generates $5 per year. Over five years, you earn roughly $25 in interest. The difference between high and low rate environments is enormous for savers.

This is why timing matters. If you have money to save and the Fed is raising rates, moving to a high-yield account sooner rather than later captures more of the higher-rate period. If the Fed is cutting rates, you have less urgency—rates are falling regardless, so the exact timing matters less.

Frequently Asked Questions

If my bank lowers my savings rate, do I have to accept it?

No. You can move your money to another bank offering a higher rate. Your bank will notify you before the change takes effect, usually 30 days in advance. That is your window to move without penalty. If you do not move, the new rate applies automatically.

How long does it take for a Fed rate change to show up in my savings account?

Online banks typically move within one to two weeks. Traditional banks usually take 30 to 90 days. Some credit unions move faster; some slower. If your bank has not moved within 90 days of a Fed change, calling and asking when they plan to adjust is reasonable.

Can I lock in a savings rate so it does not go down?

No, savings accounts do not lock in rates. Certificates of deposit (CDs) do—you choose a term (three months to five years) and your rate stays the same for that period. The tradeoff is that you cannot withdraw the money without penalty until the term ends.

Why do banks cut rates faster than they raise them?

Banks cut rates quickly to reduce what they pay out when their costs fall. They raise rates slowly because they want to keep margins wide and avoid paying more than necessary. This is normal competitive behavior, though it means savers benefit less from Fed increases than they lose from Fed cuts.

Should I move my money every time rates change?

Only if the rate difference is meaningful to you. Moving between banks takes a few days and is free, but it requires effort. If your current bank is within 0.25% of the highest available rate, the difference might not be worth the hassle. If it is 0.75% or more behind, moving makes financial sense.
