Here’s the setup: the Fed has held its target rate at 3.75% since December 10, 2025, and top online savings accounts are still paying north of 4%. That’s a small window most people are sleeping through.
If you park $10,000 in a high-yield savings account at 4% APY (that’s annual percentage yield, the interest you actually earn), you’re looking at roughly $400 a year in interest. Park that same $10,000 in a big traditional bank paying 0.01%, and you get about $1. One dollar. For the whole year.
The FDIC national average for savings sits around 0.38%, which on $10,000 works out to about $38. That’s the gap I want you to see: ~$362 a year on a single $10,000 balance, for doing basically nothing different.
And the reason it might not last much longer is what makes today interesting.
What “Above 4%” Actually Puts in Your Pocket
Knowing the number is one thing. Seeing it on your own balance is another.
| Balance | At 4.00% HYSA | At 0.38% national avg | The gap |
|---|---|---|---|
| $5,000 | ~$200/yr | ~$19/yr | ~$181 |
| $10,000 | ~$400/yr | ~$38/yr | ~$362 |
| $25,000 | ~$1,000/yr | ~$95/yr | ~$905 |
The banks are counting on you never doing that math. The math is simple: annual interest is just balance times APY.
Why Rates Might Slip From Here
HYSAs don’t set their own rates in a vacuum. They track what the Fed is doing and what short-term Treasuries are paying. Right now, both are pointing in a mildly softer direction.
The Fed funds rate has already come down 0.75 percentage points over the past year, from 4.5% in July 2025 to 3.75% today. The 26-week T-bill is yielding around 4.08% and the 52-week is at 4.12%, which is the range banks look at when pricing your savings account.
The 10Y minus 2Y Treasury spread has flattened from 0.74% in February to 0.34% now, which is bond-market speak for “we expect lower short rates ahead.” The national average 12-month CD rate has drifted from 1.76% last August to 1.68% today, another quiet signal that deposit yields are grinding lower.
If you’ve been meaning to move your cash, sooner is worth more than later.
The Cost Compounds While You’re Not Looking
One year of $362 sounds like a nice dinner out. Ten years of it, compounding, is a different animal.
$10,000 growing at 4% for a decade becomes roughly $14,800. At the 0.38% national average, that same $10,000 grows to about $10,390. That’s a gap of more than $4,400 from one 10-minute decision.
One caveat: HYSA rates float. The 4%+ you lock in this month could be 3.5% next year if the Fed keeps cutting. But even at 3%, you’re still miles ahead of 0.01% or 0.38%. The core math doesn’t break.
The One Time a CD Still Wins
If you have money you know you won’t touch for a year, and you want to lock in today’s rate before it slips, a CD makes sense. You give up flexibility for a fixed yield.
For everything else, emergency fund, down payment, next year’s tax bill, an HYSA is the better fit. Savings accounts are for money with a job. Long-term wealth-building money belongs in low-cost index funds, not any savings product.
How to Actually Move the Money (It Takes About 10 Minutes)
- Pick an online bank with an APY in the 3.75% to 4.15% range, no monthly fees, no minimum balance, and FDIC insurance (that covers you up to $250,000 per depositor if the bank fails).
- Have your ID and Social Security number ready. Applications ask for both, plus your address and employment info.
- Link your existing checking account during signup. Transfers between banks typically clear in 1 to 2 business days.
- Automate a monthly transfer. Even $50 or $100 a month means the habit runs itself. Keep your current checking account if you love it; you’re only moving savings.
- Set a calendar reminder to check the APY once a quarter. If your rate drops well below the market, move again.
What It All Means
The window where HYSAs pay above 4% is still open, but the door isn’t propped forever. Core PCE inflation is running at the 90.9th percentile of its 12-month range, which gives the Fed cover to hold, but the flattening yield curve says markets expect cuts eventually.
You don’t need to time anything. You just need to stop letting a big bank keep the $362. Open the account today, link it, fund it, and let the automation do the rest.
