Synchrony Bank HYSA Review (2026)
Quick take: Synchrony is one of the highest-yielding mainstream HYSAs (~4.35% APY) AND it's one of the only online savings accounts that ships an ATM card with the Plenti network. No minimum, no monthly fees, FDIC-insured. Among pure-savings options, Synchrony is hard to beat.

Rate history 2020-2026
The single most important fact about a HYSA: the rate is variable. Here is how this account's APY moved through the last Fed cycle.
| Year | Approx APY |
|---|---|
| 2020 | 0.55% |
| 2021 | 0.50% |
| 2022 | 3.50% |
| 2023 | 4.75% |
| 2024 | 4.65% |
| 2025 | 4.40% |
| 2026 (now) | 4.35% |
Source: archived rate disclosures and publicly reported HYSA tracking. Exact dates of rate changes vary; figures shown are year-end snapshots. The takeaway: this account dropped 80%+ of its yield from 2019 to 2021 when the Fed cut, then recovered as the Fed hiked 2022-2023. A future Fed-cut cycle will repeat the pattern.
What we like
- Top-tier APY - usually 10-30 bps above Marcus/Ally
- ATM card included (rare for an online-only HYSA) with $5/mo out-of-network rebate
- No minimum, no monthly fees, FDIC-insured
- Strong CD lineup if you want to ladder - 12-mo CD typically 25-50 bps above HYSA
- Synchrony Financial backing is solid - investment-grade credit
What we don't
- No checking account - savings-only, hub-and-spoke setup needed
- Variable rate, Fed-cycle exposed
- Outbound wire $25
- Mobile app gets mixed reviews - functional but not class-leading
- Customer service phone hours are weekday-business only for some account actions
Who this is best for
Yield-focused savers who want a pure savings account with ATM access and don't need checking. The default 'second best' to Marcus for emergency fund deployment.
When a MYGA beats this HYSA
HYSAs are the right home for emergency fund + 1-12 months of cash. For money you genuinely won't need for 3+ years, a MYGA (Multi-Year Guaranteed Annuity) typically wins on three fronts at once: higher rate, contractually locked, and tax-deferred.
3-year horizon math at $250,000
Assumptions: 32% federal + 9.3% CA bracket (combined 41.3% marginal on ordinary income). Synchrony Bank HYSA at ~4.35% (variable, assume held flat - generous). 3-yr MYGA at 5.40% guaranteed (top-of-market 2026, A-rated carrier).
| Vehicle | Gross yield | After-tax yield (annual) | Ending value (3 yr) |
|---|---|---|---|
| Synchrony Bank HYSA | ~4.35% | ~2.49% | ~$269,164 |
| 3-yr MYGA @ 5.40% | 5.40% | Deferred (compounds gross) | $292,706 (at maturity) |
| MYGA advantage | +115 bps | +gross compounding | +$23,542 / +8.7% |
The MYGA dollar gain at maturity is taxable when withdrawn, but at withdrawal you can spread the tax across multiple years (laddered or annuitized) or push it into a lower bracket in retirement. The HYSA tax is paid every year, no deferral.
5-year horizon math at $250,000
5-yr MYGA at 5.65% guaranteed vs. Synchrony Bank HYSA at ~4.35% (held flat - aggressive assumption given 5 Fed cycles in past 20 years averaged 200+ bps moves).
| Vehicle | Ending value (5 yr) | Net gain |
|---|---|---|
| Synchrony Bank HYSA (after annual tax) | ~$282,706 | +$32,706 |
| 5-yr MYGA @ 5.65% (gross) | $329,090 | +$79,090 |
| MYGA advantage at maturity | +$46,384 | +18.5% |
Why the gap widens at 5 years: Tax-deferred compounding. The HYSA pays tax on every year's interest; the MYGA compounds gross interest on interest for the full term. Combined with the rate advantage, the gap is meaningful at any balance above ~$50K.
When the HYSA wins
The HYSA wins when you actually need liquidity. If there's a 30%+ chance you'll touch the money in the next 3 years, the MYGA surrender charges (typically 7-9% in years 1-3, decreasing to 0%) eat the rate advantage. Keep your emergency fund + 12 months of expected outflows in the HYSA. Then evaluate the MYGA for the surplus.
Complexity Score: A+
Every Goldstein review assigns a complexity score - because complexity is where savers and buyers get burned. HYSAs are the simplest financial product on the market: deposit money, earn variable interest, withdraw anytime. No surrender charges, no riders, no benefit-base separation, no caps or participation rates. Grade: A+ (Simple).
Note: simple does not mean optimal. A 4.25% HYSA taxed annually at 41% can return less, after-tax, than a 5.40% MYGA taxed only at withdrawal. Simplicity is a feature, not a financial result.

Bottom line
Synchrony Bank runs a solid HYSA. The trade-offs are the same as every HYSA on the market: rate is variable (Fed-driven), interest is taxed annually at ordinary rates, no contractual minimum rate floor. For emergency fund and 1-12 month cash, this account does its job. For 3+ year money, the math typically favors a 3-5 year MYGA at 5.40-5.65% locked, tax-deferred, A-rated carrier - somewhere in the 8-19% net advantage range at typical balances. Get the math run before you commit either way.
