Best HYSA for a 70-Year-Old (2026), Pre-RMD Income Planning
Quick take: At 70, two things change: Social Security maxes out (the 32% delayed-credit advantage is now banked) and you have three years before RMDs start at 73. The HYSA's job changes too, it is now the staging account for RMDs, charitable QCDs, and the last clean window to do Roth conversions before the IRS forces distributions. Top 5 ranked below, plus the MYGA math for the dollars you will not touch for 5+ years.

Why this HYSA wins at age 70
At 70 the HYSA is the operational hub of retirement income. Social Security is now at its max (32% above FRA). Pension checks, if any, are flowing. RMDs will start in 3 years. The HYSA collects all of this and disburses to checking. Three features matter more than 10 bps of yield:
- Statement clarity for tax prep. At 70+, the 1099-INT goes to the CPA. Banks that issue clean, single-page 1099s save fees and errors.
- Phone support. When the spouse helping manage accounts gets stuck, U.S.-based phone support (Discover, Marcus) beats chat-only platforms.
- Multiple POD beneficiaries. At 70, the beneficiary list often includes adult children, grandchildren, and charities. Confirm the bank allows multiple POD names.

FDIC and the 70-year-old's balance sheet
By 70, many couples have $300K-$1M in conservative cash spread across HYSAs, CDs, and money market accounts. FDIC math:
- Individual account per spouse: $250K each = $500K covered at one bank
- Joint account: another $500K covered at the same bank ($250K per co-owner)
- Revocable trust: $250K per unique beneficiary, so a trust with three kids covers $750K at one bank
A couple with two individual + one joint + one trust account at the same bank can cover $1.75M-$2M+ at a single FDIC institution. Confirm the math with the bank's deposit-insurance calculator before relying on it.
Pre-RMD window (ages 70-72): the 3-year planning gift
From 70 to 72, you have three tax years with no forced distributions. This is the cleanest window for:
- Roth conversions. Convert IRA dollars at known marginal rates before RMDs push you into the next bracket at 73.
- QCDs starting at 70.5. You can do qualified charitable distributions from the IRA up to $105,000/yr starting at 70.5, they count toward future RMDs and are excluded from MAGI.
- Locking 7- to 10-year MYGAs. A 7-year MYGA bought at 70 pays out at 77, right when you may want simpler income. Lock today's rate.
When a MYGA beats a HYSA at 70
For the dollars you will not touch for 5+ years (typically the second cash bucket), a MYGA's locked rate plus tax deferral wins on math. The 2026 spread:
| Vehicle | 2026 yield | Rate behavior | Tax (non-IRA) |
|---|---|---|---|
| HYSA | 4.25-4.50% | Resets monthly, can drop fast | 1099-INT annually |
| 5-yr MYGA | 5.00-5.75% | Locked 5 yrs | Tax-deferred until withdrawal |
| 7-yr MYGA | 5.25-6.00% | Locked 7 yrs | Tax-deferred until withdrawal |
On $150K over 7 years assuming HYSA averages 3.50% and MYGA at 5.50% locked: HYSA grows to ~$191K, MYGA grows to ~$217K. Roughly $26K of extra return on the same risk profile.
Common mistakes 70-year-olds make
- Overbuilding the HYSA. A $400K HYSA at 70 yielding 4.40% (taxed) is $5K-$10K/year behind a $400K MYGA at 5.50% (deferred). Multiply by 5-7 years.
- Missing the QCD window. Starting at 70.5, IRA-to-charity transfers (QCDs) skip MAGI entirely. The HYSA stays untouched; the charity gets pre-tax dollars; IRMAA does not move.
- Not coordinating RMDs with the HYSA. Schedule RMDs to land in the HYSA before December. Late-December RMDs clog with year-end processing.
- Forgetting beneficiary updates. Adult children may have divorced or moved. Confirm POD names every 12 months.
