The main places to open a HYSA are online banks, credit unions, and some traditional banks

A high-yield savings account (HYSA) can be opened at three types of institutions: online-only banks, credit unions, and brick-and-mortar banks that offer them alongside regular savings accounts. Online banks typically offer the highest rates because they have lower overhead costs. Credit unions often offer competitive rates to their members. Traditional banks usually offer lower rates but may give you the option to manage everything in one place if you already bank there.

The account itself works the same way regardless of where you open it: you deposit money, earn interest monthly, and can withdraw funds, though federal rules limit you to six withdrawals per month from a savings account (this limit is enforced less strictly now, but many banks still explore it). The main difference between institutions is the rate they pay, the fees they charge, and how you access your money.

Key Takeaways

  • Online banks currently pay the highest rates on HYSAs because they operate without physical branches and pass those savings to customers.
  • Credit unions may offer competitive rates to members and sometimes waive fees that online banks charge, though you must meet membership requirements.
  • Traditional banks let you open a HYSA at a branch you already visit, but their rates are usually lower than online or credit union options.
  • All HYSA deposits are insured up to $250,000 per account holder per institution by the FDIC (banks) or NCUA (credit unions), so the institution's size does not affect your protection.

Online banks: highest rates, no physical branches

Online banks such as Marcus, Ally, American Express Personal Savings, and Wealthfront Cash Account operate only through websites and mobile apps. They do not have branches, so they do not pay for building leases, tellers, or branch staff. That cost savings translates into higher interest rates. As of early 2024, online banks were paying between 4.5% and 5.35% APY on HYSAs, though rates change frequently and vary by institution.

To open an account, you visit the bank's website, provide your Social Security number, verify your identity (usually through your driver's license or by answering security questions), and link a checking account to transfer money in. The whole process takes 10 to 15 minutes. You can deposit money by electronic transfer from another bank, and withdrawals go back to that linked account. There are no monthly fees at most online banks, though some charge fees if you fall below a minimum balance (usually $0 to $25,000 depending on the bank).

The trade-off is that you cannot walk into a branch or speak to someone in person. If you need to resolve a problem, you contact customer service by phone, email, or chat. Most online banks have 24/7 support, but response times vary.

Credit unions: member-only accounts with competitive rates

Credit unions are member-owned financial institutions that often pay rates competitive with online banks. To open a HYSA at a credit union, you must first become a member, which usually requires living or working in a specific area, belonging to a certain employer, or joining an organization the credit union serves. Some credit unions have opened membership to anyone in the United States, so it is worth checking whether you are may be able to access for one near you.

Credit unions typically charge lower fees than traditional banks and sometimes lower fees than online banks. Some waive monthly maintenance fees entirely or do not charge overdraft fees. Rates on HYSAs at credit unions vary widely—some pay as much as online banks, while others pay less. You can find credit unions in your area through the CO-OP Network or Alliant Credit Union's locator tool.

The advantage of a credit union is that you may have a physical branch to visit and a member-focused culture, plus competitive rates. The disadvantage is that you must meet membership requirements and that credit union hours and services vary by location. If you move or change jobs, you may lose membership.

Traditional banks: convenience with lower rates

Banks such as Chase, Bank of America, Wells Fargo, and Citibank offer HYSAs to customers who already have checking accounts with them. The rate is usually lower than online banks or credit unions—often between 0.01% and 2% APY—because traditional banks have higher operating costs and less pressure to compete on rate alone.

The advantage is convenience: you can open the account at a branch, speak to someone in person, and manage both your checking and savings in one place. If you already have a relationship with the bank, you may may have access to for a higher rate or waived fees. Some banks offer rate bonuses if you set up automatic transfers or maintain a certain balance.

The disadvantage is that the rate you earn is significantly lower than you would earn elsewhere. If you have $10,000 in a HYSA earning 0.5% at a traditional bank versus 5% at an online bank, you earn $50 per year instead of $500. Over time, that difference compounds.

How to compare HYSAs across institutions

When deciding where to open a HYSA, compare the current APY, any monthly fees, minimum balance requirements, and how you will deposit and withdraw money. APY is the most important factor because it directly determines how much you earn. Check the bank's website or call to confirm the current rate, since rates change frequently and may vary based on your balance.

Look for accounts with no monthly maintenance fees and no minimum balance requirement, or with minimums you can easily meet. If you plan to make frequent transfers, confirm that the bank does not charge per-transaction fees or limit the number of transfers you can make per month. Check whether the bank is FDIC-insured (for banks) or NCUA-insured (for credit unions) to confirm your deposits are protected up to $250,000.

You can also use rate-comparison websites such as Bankrate, DepositAccounts, or DepositAccounts to see current rates across multiple institutions. These sites update rates regularly and let you filter by features you care about, such as no fees or no minimum balance.

What happens after you open the account

Once your account is open, you link it to a checking account at the same bank or a different bank. You then transfer money into the HYSA. The money sits there and earns interest, which is deposited into the account monthly. You can withdraw money at any time, though the withdrawal goes back to the linked account (you cannot withdraw cash at a branch unless the institution has branches).

Interest rates on HYSAs are variable, meaning the bank can change the rate at any time. When the Federal Reserve raises or lowers interest rates, banks typically adjust HYSA rates within days or weeks. If rates fall, your earnings fall with them. If rates rise, your earnings rise. This is normal and expected.

You should review your account's rate every few months. If another bank is paying significantly more and you do not have a strong reason to stay (such as a bonus or relationship benefits), you can open a new account elsewhere and transfer your money. There is no penalty for moving your savings to a different institution.

Frequently Asked Questions

Is my money safe at an online bank?

Yes, as long as the online bank is FDIC-insured. FDIC insurance protects your deposits up to $250,000 per account holder per bank, regardless of whether the bank has physical branches. You can verify FDIC insurance status on the FDIC's website by searching the bank's name.

Can I open a HYSA if I do not have a checking account?

Most online banks require you to link an external checking account to transfer money in and out. Some credit unions and traditional banks let you open a HYSA without an existing account at their institution, but you will still need a way to move money—usually a checking account somewhere. A few online banks offer checking accounts, so you could open both at once.

How long does it take to open a HYSA?

Online banks typically take 10 to 15 minutes to open an account. Credit unions may take longer if you need to visit a branch or complete membership paperwork. Traditional banks can open an account in minutes at a branch or online. Once opened, it usually takes one to three business days for the account to be fully active and ready to receive transfers.

What if the rate drops after I open the account?

Rates on HYSAs are variable, so banks can lower them at any time. If your bank's rate drops significantly below what other banks are paying, you can open a new account elsewhere and move your money. There is no fee or penalty for closing a HYSA or moving your savings to a different institution.

Can I have multiple HYSAs?

Yes. You can open HYSAs at multiple banks to take advantage of different rates or to organize your savings by goal. Each account is insured separately up to $250,000 by the FDIC or NCUA, so your total protection increases with each account at a different institution.
