Interest rates change constantly, but most daily moves are small and won't affect your account

Interest rates shift nearly every business day because they respond to what's happening in the economy right now. The Federal Reserve (the central bank of the United States) meets eight times a year to set a target range for the federal funds rate—the rate banks charge each other for overnight loans. When the Fed changes that rate, or when markets expect it to change, savings account rates, CD rates, and money market rates move in response.

A single day's movement is usually tiny—a quarter of a percent or less. You won't see your account balance jump because of a daily shift. What matters more is the direction over weeks and months: whether rates are trending up or down, and whether your bank has actually updated the rate it pays you.

Key Takeaways

  • The Federal Reserve sets a target range for the federal funds rate eight times per year, and market rates move on those announcement days and in response to economic news.
  • A single day's rate change is usually small enough that it won't change what you earn on a savings account or CD in any meaningful way.
  • Your bank controls when and how much it raises or lowers the rate it pays you—the Fed's rate change does not automatically update your account.
  • Rates tend to move together over time, but the speed and size of changes vary by bank and by account type.

How the Federal Reserve's decisions drive daily rate movements

The Fed's eight scheduled meetings happen roughly every six weeks. On the day the Fed announces a decision, financial markets react immediately, and banks adjust the rates they offer to savers and borrowers. If the Fed raises its target rate, market rates for savings accounts and CDs typically rise the same day. If the Fed signals it might cut rates in the future, rates may fall even before an official cut happens.

Between Fed meetings, rates still move because of economic news—inflation reports, employment data, or signals from Fed officials. Markets are constantly pricing in what they think the Fed will do next. This is why you might see rate changes on days when the Fed did nothing.

Why your bank's rate might not match what you see in the news

When you read that "savings rates hit 4.5%," that's usually the highest rate available somewhere in the market—often at an online bank or credit union. Your own bank's rate may be lower, and it may not have changed at all, even if the market rate did.

Banks decide independently how much interest to pay. A large national bank might move slowly, raising rates only after several Fed increases. An online bank competing for deposits might raise rates faster. Your bank might have raised rates three months ago and chosen not to raise them again, even though other banks did.

The only way to know what your bank is paying is to check your account statement or log in to see your current rate. News about market rates tells you what's available elsewhere, not what you're earning.

The difference between a Fed rate change and what you actually earn

The federal funds rate is the rate banks charge each other. It's not the rate your bank pays you. The Fed's rate is a floor and a signal—when it goes up, banks have more incentive to pay savers more, because they can earn more from lending. But banks are not required to pass along the full increase, and many don't.

During periods when the Fed was raising rates (2022 to 2023), online banks raised savings account rates quickly and often. Traditional banks raised rates more slowly. Now that the Fed has paused, some banks are holding rates steady while others are beginning to lower them. The gap between what the Fed's rate is and what you earn depends on competition and your bank's strategy.

What happens to CDs and money market accounts when rates move

A CD (certificate of deposit) locks in a rate for a set term—three months, one year, five years. Once you buy a CD, that rate doesn't change, even if market rates fall the next day. This is why CDs are useful when rates are high: you lock in the rate before it drops.

A money market account is a savings account that usually pays a higher rate and lets you write checks or make transfers. Its rate can change at any time, and it usually does when market rates move. If rates fall, your money market rate falls with it. If rates rise, your bank may or may not raise your rate—that's up to the bank.

Savings accounts work the same way: the rate can change whenever your bank decides to change it. Banks are not required to tell you in advance, though many send a notice after the change takes effect.

How to track whether rate changes actually affect you

The simplest way is to check your statement each month and note the interest you earned. If that number is growing, your rate is either staying the same and you're earning more on a larger balance, or your rate went up. If it's shrinking, your rate probably fell.

You can also log into your account and look for the current rate listed under your account details. Some banks show the rate on the main dashboard; others bury it in account settings. If you can't find it, call or use the bank's chat feature and ask what rate you're currently earning.

If you're shopping for a new account, compare the rates banks are offering, but understand that those rates can change. A CD rate is locked in once you buy it. A savings account rate can move at any time. Ask your bank whether it plans to lower rates if the Fed cuts, or whether it will hold rates steady.

Why some people move money when rates change

When rates are falling, savers sometimes move money from a savings account (which can drop at any time) into a CD (which locks in the current rate). When rates are rising, the opposite happens: people wait for rates to stop rising before locking money into a CD, because they don't want to lock in a rate that will soon be outdated.

This is a real choice you can make, but it requires paying attention to the direction rates are moving and thinking about how long you can leave the money untouched. A CD with an early withdrawal penalty can cost you money if you need the cash before the term ends.

Frequently Asked Questions

If rates went up today, will my savings account rate go up tomorrow?

Probably not. Your bank controls when it raises your rate, and many banks wait days or weeks after a rate increase before passing it along. Some banks don't raise rates at all. Check your account in a few days to see if your bank has updated it.

Should I move my money if I see rates went up somewhere else?

Only if your current bank is paying significantly less and you're willing to move the money. Switching banks takes a few days and requires opening a new account. If the rate difference is small (less than 0.5%), the hassle may not be worth it. If it's large, moving makes sense.

What does it mean when the news says "rates hit a 23-year high"?

It means the highest rate available in the market is higher than it's been in 23 years. This is useful context for understanding where we are in the economic cycle, but it doesn't tell you what your bank is paying. Your rate could be much lower.

If I lock money in a CD, am I making the right choice?

That depends on whether you think rates will fall or rise. If you believe rates will fall, locking in the current rate protects you. If you think rates will keep rising, waiting might get you a higher rate later. No one can predict this with certainty, so consider how long you can afford to leave the money untouched.

Why do some banks raise rates faster than others?

Banks compete differently. Online banks often raise rates quickly to attract deposits from people shopping for the best rate. Local or national banks may raise rates more slowly because they have other ways to attract customers, like branch locations or existing relationships. Both strategies are normal.
