How Often Do HYSA Rates Update? (2026)
What "variable rate" actually means
When you open an HYSA, the bank pays the APY they're advertising that day. They are not contractually obligated to pay that APY tomorrow, next month, or next year. The account terms typically say something like: "The interest rate may change at any time at the bank's discretion."
This is the fundamental difference between an HYSA (variable) and a CD or MYGA (fixed for term).
How often do top banks actually change rates?
Based on historical patterns 2020-2026:
- Marcus by Goldman Sachs: Changes 6-10x/year, usually within 7-14 days of an FOMC decision
- Ally Bank: Changes 6-10x/year, typically within 1-2 weeks of Fed moves
- SoFi: Changes 8-12x/year — more reactive than peers
- Discover: Changes 4-8x/year — tends to be slower to follow Fed cuts
- American Express: Changes 4-8x/year — similar to Discover
- Synchrony: Changes 6-10x/year
- Capital One 360: Changes 4-8x/year — slower, larger steps
The pattern: banks tend to raise rates fast (to attract deposits when the Fed hikes) and lower rates fast too (to protect margins when the Fed cuts). Lag is typically 7-14 days from the FOMC announcement.
What drives the rate changes
- Federal Reserve policy — when the Fed Funds rate moves, HYSA APYs move within 1-2 weeks. Fed Funds at 5.50% in 2023-2024 = HYSAs at ~4.50-5.30%. Fed Funds cut to 4.50% in 2024-2025 = HYSAs dropped to ~4.10-4.65%.
- Competitive dynamics — if SoFi raises to 4.80% and Marcus stays at 4.40%, Marcus loses deposits. Marcus will often respond within a few weeks.
- The bank's deposit needs — if a bank wants to grow deposits to fund lending, they raise APYs. If they're flush, they let APYs drift down.
- Market funding costs — when bond yields rise, banks can afford to pay more on deposits.
The 2022-2026 rate history (real data)
| Date | Fed Funds Rate | Top Online HYSA APY |
|---|---|---|
| Jan 2022 | 0.25% | 0.50-0.60% |
| Jul 2022 | 2.50% | 1.50-2.10% |
| Jan 2023 | 4.50% | 3.30-3.75% |
| Jul 2023 | 5.50% | 4.30-4.85% |
| Jan 2024 | 5.50% | 4.50-5.30% |
| Sep 2024 | 5.00% | 4.40-5.00% |
| Jan 2025 | 4.50% | 4.10-4.70% |
| Jun 2026 | ~4.25% | 4.10-4.65% |
The lesson: HYSA APYs went from 0.50% to 5.30% to ~4.40% in 4 years. You can't plan around a variable rate. You can only plan around the current rate and accept rate risk.
How banks notify you of rate changes
- Most banks: silently. The new APY just appears on the next monthly statement.
- A few banks send an email when the rate changes — usually for cuts, sometimes for increases.
- Promo-rate banks send notification when the intro APY ends (e.g., "your 5.50% intro rate ends next month, then drops to standard 3.50%"). Top online banks rarely use promo structures.
You can track APY changes manually: bookmark the bank's rate page, check monthly. Or check sites like Bankrate, NerdWallet, DepositAccounts.com that aggregate online HYSA rates weekly.
"Why doesn't the bank guarantee my rate?"
Because the bank funds your interest payments out of its lending margin. A bank lends your $100K out as a mortgage at, say, 7%. If they pay you 4.5%, they keep 2.5% margin. When the Fed cuts and the bank's lending yields drop to 6%, they cut your APY to 3.5% to maintain margin. They literally can't guarantee a rate they don't know they can fund 5 years out.
Insurance carriers funding MYGAs solve this differently: they invest the premium in long-duration corporate bonds (5-10 year maturities) at fixed yields, then pay you a fixed APY backed by that bond's coupon. They can guarantee a 5-year rate because they bought the matching 5-year bond.
What this means for your money
- Emergency fund + 0-24 month cash: HYSA is the right tool. Variable rate doesn't matter much over short periods.
- 3-10 year cash (parked): Variable rate is a real risk. A 1% rate cut on $100K = $1,000/year. A locked MYGA at 5.65% removes this risk.
- 10+ year retirement money: Neither HYSA nor MYGA is the right tool. Use diversified retirement accounts.
Frequently Asked Questions
Does the Fed directly set HYSA rates?
No. The Federal Reserve sets the Fed Funds rate (overnight bank-to-bank lending). HYSA rates are set by each bank independently, but they track Fed Funds closely. When the Fed cut from 5.50% to 4.50% in 2024-2025, top HYSAs dropped from 5.30% to ~4.40%.
Will my HYSA rate drop tomorrow?
It could. Variable rate accounts can change at any time without notice. Historically, top online banks change rates 4-12 times per year, usually within 1-2 weeks of a Fed decision. The next FOMC meeting is the best signal for near-term rate moves.
Is there an HYSA that locks the rate?
No. By definition, an HYSA is variable. The fixed-rate equivalents are: (1) CDs — locked for term (3 mo to 5 yr typical); (2) Treasury bills — fixed yield, term-locked; (3) MYGAs — locked for 3-10 years, insurance contract from carrier.
How quickly do banks raise rates when the Fed hikes?
Top online banks usually raise APYs within 7-14 days of a Fed hike. Big brick-and-mortar banks (Chase, BoA, Wells) often don't raise savings APYs at all — they keep them at 0.01-0.05%. The whole online HYSA market exists because brick-and-mortar banks don't pass Fed hikes to savers.
Why is my HYSA APY lower this month than last month?
Either the Fed cut, or your bank cut to match peers, or you fell below a minimum-balance APY tier. Check the bank's current rate page and verify your balance is above any tier threshold. If both check out, the bank just cut — this is normal for a variable rate account.
Do credit unions update rates faster or slower than banks?
Credit unions typically update less frequently (2-6x/year) and tend to move slower in both directions. Top credit union savings APYs are sometimes higher than top bank HYSAs, but the gap closes within 1-2 months of major Fed moves.
How can I lock today's HYSA rate for 5 years?
You can't — not at an HYSA. To lock today's ~4.50% rate for 5 years, you need a CD (FDIC-insured, ~4.00-4.50% for 5-year CDs in 2026) or a MYGA (state guaranty fund insured, 5.50-5.75% for 5-year terms from A-rated carriers). MYGAs typically beat 5-year CD rates by 100-150 bps.
Want a fixed rate locked for 3-10 years instead of a variable HYSA?
Compare your HYSA APY against current MYGA rates — free, independent.
HYSA rates move every month with the Fed. If you want a rate locked for 3, 5, 7, or 10 years on cash you won't touch, a MYGA (multi-year guaranteed annuity) is the closest equivalent. Current top MYGA rates: 5.40-5.75% for 3-5 year terms, fixed. Tax-deferred. State guaranty fund backed.
Drop your info — within 24 hours, you'll get current MYGA rates side-by-side with your HYSA, surrender schedules, carrier ratings, and a no-pressure 15-minute call if you want one.
