Key Takeaways
- Hyperion Bank’s Exclusive Money Market is guaranteeing 4.50% APY for six months—letting you lock in a top rate yet withdraw when you like.
- That rate guarantee matters, since likely Fed cuts are expected to push savings and money market yields lower in the months ahead.
- Hyperion’s offer beats even the best CDs by offering easy withdrawals and a top yield—but you’ll need at least $10,000 on deposit to qualify.
This APY Guarantee Can Protect Your Savings if the Fed Keeps Cutting
For most savers, earning the best return on your cash usually means giving up some flexibility. Savings and money market accounts keep your funds liquid, but their rates can drop anytime. Certificates of deposit (CDs) meanwhile guarantee a fixed return, but you have to lock away your money for months—or even years—to earn it.
After two Federal Reserve rate cuts this fall, markets widely expect more reductions in the months ahead. That means today’s top savings and money market rates may not last much longer. Locking in a return—something you can rarely do outside of a CD—has become especially valuable for anyone hoping to enjoy today’s high yields into 2026.
That’s what makes Hyperion Bank’s Exclusive Money Market account stand out. It already tops our daily ranking of the best money market accounts with a nation-leading 4.50% APY. What’s unusual is the bank guaranteeing that rate for six months from the date you open your account—a feature virtually unheard of among liquid accounts.
Why This Matters
If the Fed keeps cutting interest rates, today’s top savings yields will fall. Hyperion’s offer delivers a rare double win—locking in a stellar 4.50% return while keeping your money available whenever you need it.
What To Know About Hyperion Bank’s 4.50% Offer
If you’re wondering what defines a money market account, it’s essentially a savings account with a key added feature. Both are offered by banks and credit unions insured by the FDIC or NCUA. They pay variable interest and let you move money in and out freely. The difference is that a money market account allows paper check-writing. If that feature doesn’t matter to you, money market and savings accounts are largely interchangeable—simply choose whichever is paying a higher rate.
Though money market accounts often pay slightly less than the top high-yield savings accounts, Hyperion’s 4.50% APY is unusually competitive. While our daily ranking of the best high-yield savings accounts currently reaches up to 5.00%, the top offers come with conditions. Only one—Pibank’s 4.60% APY—beats Hyperion’s rate without any strings attached. But like the rest of the high-yield savings accounts in our ranking, Pibank’s rate can change at any time.
To earn the 4.50% APY, you’ll need to maintain at least $10,000 in the account, and only new money qualifies—meaning funds not already on deposit with Hyperion. Your balance remains fully accessible, allowing you to deposit or withdraw anytime. Just note that if your balance dips below $10,000, you’ll lose the 4.50% APY, so it’s smart to keep a cushion above that threshold.
Why This Money Market Account Is Better Than Even the Best CDs
While Hyperion’s 4.50% APY matches the nation’s highest CD rate, that top offer applies only to a four-month CD—meaning Hyperion guarantees your rate for two extra months. For a true apples-to-apples comparison on rate locks, the best six-month CDs currently pay 4.40%, giving Hyperion’s money market account the edge on both yield and flexibility.
It’s a rare combination: a liquid account that pays more than leading CDs while letting you withdraw anytime without penalty. For savers looking to lock in a high return that lasts well into the new year—no matter what the Fed does next—Hyperion’s 4.50% guarantee delivers the best of both worlds
Daily Rankings of the Best CDs and Savings Accounts
We update these rankings every business day to give you the best deposit rates available:
Important
Note that the “top rates” quoted here are the highest nationally available rates Investopedia has identified in its daily rate research on hundreds of banks and credit unions. This is much different than the national average, which includes all banks offering a CD with that term, including many large banks that pay a pittance in interest. Thus, the national averages are always quite low, while the top rates you can unearth by shopping around are often 5, 10, or even 15 times higher.
How We Find the Best Savings and CD Rates
Every business day, Investopedia tracks the rate data of more than 200 banks and credit unions that offer CDs and savings accounts to customers nationwide and determines daily rankings of the top-paying accounts. To qualify for our lists, the institution must be federally insured (FDIC for banks, NCUA for credit unions), and the account’s minimum initial deposit must not exceed $25,000. It also cannot specify a maximum deposit amount that’s below $5,000.
Banks must be available in at least 40 states to qualify as nationally available. And while some credit unions require you to donate to a specific charity or association to become a member if you don’t meet other eligibility criteria (e.g., you don’t live in a certain area or work in a certain kind of job), we exclude credit unions whose donation requirement is $40 or more.
