The highest APY changes weekly, so check the current rate before you open an account

High-yield savings accounts (HYSAs) from online banks currently pay between 4.5% and 5.35% APY, depending on the bank and the week you check. The rate leaders shift constantly because banks raise and lower their rates in response to Federal Reserve decisions and competition. An account paying 5.2% one month may drop to 4.8% the next. This means the "highest" account today may not be the highest next month.

The practical difference between a 4.5% account and a 5.35% account is real: on $10,000, that 0.85% gap costs you about $85 per year in lost interest. But chasing the absolute highest rate by moving money between banks every few weeks usually costs more in time and hassle than the extra interest is worth. A better strategy is to pick an account paying a competitive rate from a bank you trust, then check the rate once or twice a year.

Key Takeaways

  • HYSA rates change weekly and vary by bank; the highest-paying account today may not be the highest next month.
  • Online banks (like Marcus, Ally, and American Express) typically pay higher rates than brick-and-mortar banks because they have lower overhead costs.
  • A difference of 0.5% APY on $10,000 means about $50 per year in lost interest, so small rate differences matter less than account stability and access.
  • You can check current rates on sites like Bankrate, DepositAccounts, or the banks' websites directly before opening an account.
  • Some accounts offer promotional rates that drop after a set period, so read the fine print to confirm the rate is permanent.

Where to find the current highest rates

Rate comparison sites update daily and show you what each bank is paying right now. Bankrate.com, DepositAccounts.com, and DepositAccounts list HYSAs sorted by APY. You can also visit the banks' websites directly—Marcus, Ally, American Express Personal Savings, and Synchrony all publish their rates on their homepages. The rate you see online is the rate you get when you open the account that day.

When you compare rates, look for two things: the APY (annual percentage yield, which includes compounding) and whether the rate is permanent or promotional. Some banks offer a higher rate for the first three or six months, then drop it. The fine print will say "introductory rate" or "promotional rate" if this applies. If the site does not mention a promotional period, the rate is usually permanent—but confirm by reading the account terms or calling the bank.

Why online banks pay more than traditional banks

Online banks have no physical branches, so they spend far less on rent, staff, and equipment. They pass those savings to customers by paying higher interest rates on savings accounts. A traditional bank with hundreds of branches cannot afford to match an online bank's rate and still cover its costs. This is why you will almost never see a brick-and-mortar bank's HYSA rate above 4.5%, while online banks regularly pay 5% or more.

The trade-off is convenience: you cannot walk into a branch to deposit cash or speak to someone in person. Most online banks let you deposit checks by phone camera and transfer money to and from other banks electronically. If you rarely need to deposit cash, an online bank's higher rate is worth the switch. If you deposit cash weekly, you may need to stay with a bank that has branches near you.

How to decide between accounts paying similar rates

Once you have narrowed the field to accounts within 0.25% of each other, rate differences stop mattering much. Instead, compare what each bank offers in terms of access and features. Can you link external bank accounts and transfer money easily? Does the bank charge fees for anything? Can you set up automatic transfers? Does the account come with a debit card? Some HYSAs have no debit card and are meant purely for saving, while others let you withdraw money instantly.

Also check the bank's customer service reputation. Read recent reviews on Trustpilot or the bank's own website to see whether people report problems getting money out, long wait times, or account freezes. A bank paying 5.3% is not worth it if you cannot reach customer service when you need to. Stick with banks that have been operating for at least five years and are FDIC-insured (all the major online banks are).

What happens to your rate if the Federal Reserve changes interest rates

The Federal Reserve sets a target range for the federal funds rate, which influences how much banks pay on savings accounts. When the Fed raises rates, banks usually raise HYSA rates within days or weeks. When the Fed cuts rates, banks cut HYSA rates just as fast. This means the 5.2% rate you locked in today could drop to 4.5% within a few months if the Fed cuts rates.

You cannot lock in a rate permanently at most banks. The rate is variable, meaning it can change at any time. Some banks give you notice before they lower your rate, but they are not required to. If rates drop and you want a higher rate, you can move your money to a different bank—there is no penalty for closing a savings account. This is why checking rates once or twice a year makes sense: if your bank's rate falls significantly behind, you can move to a competitor.

Promotional rates and what to watch for

Some banks advertise a high rate for new customers only, then drop the rate after a set period—usually three to six months. For example, a bank might offer 5.5% for the first 90 days, then drop to 4.5% after that. If you plan to keep money in the account long-term, this promotional rate is misleading. You will earn the higher rate for only a few months, then earn less than you would at a competitor's permanent rate.

Read the account terms or call the bank before you open the account and ask: "Is this rate permanent, or does it drop after a certain date?" If it drops, ask what the permanent rate will be. Some banks will tell you; others will not. If they will not say, assume the rate will drop to their standard rate, which is usually lower than what competitors offer. Promotional rates can make sense if you are moving money you plan to withdraw anyway, but for long-term savings, a permanent competitive rate is safer.

Frequently Asked Questions

Can I move my money to a different HYSA if rates drop?

Yes. Closing a savings account has no penalty, and you can transfer your balance to another bank electronically. The transfer usually takes three to five business days. There is no limit to how many times you can move money between banks, though moving frequently is time-consuming and may not be worth small rate differences.

Is my money safe in an online bank?

Yes, if the bank is FDIC-insured. FDIC insurance protects up to $250,000 per account holder per bank. All major online banks (Marcus, Ally, American Express, Synchrony) are FDIC-insured. You can verify a bank's insurance status on the FDIC website by searching for the bank's name.

Do I have to keep a minimum balance to earn the advertised APY?

Most online HYSAs have no minimum balance requirement. You earn the full APY on any amount, even $1. Some banks may require a minimum to open the account (often $0 to $25), but once it is open, you can keep any balance. Check the account terms to confirm there is no minimum balance requirement.

What if I need to withdraw money quickly?

Online banks let you transfer money to a linked external bank account, which usually takes one to three business days. Some banks offer next-day transfers for a fee. You cannot withdraw cash directly from an online bank unless you have a debit card linked to the account. If you need cash immediately, a traditional bank with branches may be more convenient.

How often do HYSA rates change?

Banks can change rates at any time without notice, though most announce changes a few days in advance. Rates typically move when the Federal Reserve changes its target rate, but banks may also adjust rates based on competition. Check your bank's rate once every few months to see if it has fallen significantly behind competitors.
