At $100,000, every major safety net fully covers you: FDIC ($250K cap), state annuity guaranty funds ($100K-$500K caps), and direct Treasuries (no dollar limit). The safest choice depends on yield and access, not protection. For pure principal protection: 1-year Treasury (4.50% par yield on September 25, 2026) or a 1-year FDIC CD (top national rates 4.35% to 4.50% APY on September 25, 2026). For higher yield with comparable safety: a 5-year MYGA from an A-rated carrier (about 5.50% to 6.05% on October 14, 2026).
$100,000 is small enough to fit comfortably within all the major dollar-limited safety nets:
At this dollar amount, “safest” is a meaningless ranking. All four are functionally safe. Choose based on yield, term, and access.
The conventional advice at $100K is “stay in cash, FDIC-insured.” That advice over-weights the safety differential and under-weights the yield differential. At today's rates, a 5-year MYGA pays 100 to 150 basis points more than a 5-year CD. That is $5,000 to $7,500 over five years on $100K, with both protected to the full $100K.
| Product | 5-year yield | 5-year balance | Safety net | Liquidity |
|---|---|---|---|---|
| 5-year FDIC CD | ~4.5% | ~$124,600 | FDIC $250K | Early-withdrawal penalty (6-12 months interest) |
| 5-year MYGA (A-rated carrier) | ~5.7% | ~$131,900 | State guaranty fund $250K (most states) | 10% free withdrawals/yr; surrender charge on excess |
| 5-year Treasury note | ~4.3% | ~$123,500 | U.S. government; no dollar limit | Sellable on secondary market (price fluctuates) |
| HYSA (variable) | ~4.5% today, variable | Uncertain (rate-dependent) | FDIC $250K | Liquid; no penalty |
| Money market fund (Treasury) | ~5.0% | Variable | U.S. government securities | Liquid; daily redemption |
| 3-month T-bill (rolled) | ~5.2% (as of June 2026) | Variable | U.S. government | Liquid (3-month maturity) |

A 60-year-old with $100K parked for retirement income at age 65:
For a tax-deferred home (IRA, Roth, non-qualified deferral preference): MYGA wins on yield. For state-tax-sensitive residents: Treasury wins on after-tax basis. For pure simplicity: CD wins.
“FDIC is the safest option.” No. Treasuries are backed by the full faith and credit of the U.S. government, which is the same backing as the FDIC fund itself. Treasuries have no dollar limit; FDIC has a $250K cap. For sub-$250K amounts the comparison is functionally a tie.
“Annuities are not insured.” They are insured by the state guaranty fund. They are not FDIC-insured. Different mechanism, both functioning safety nets.
“$100K is not enough for an annuity.” $100K is a fine MYGA size. Most carriers have minimums of $10K-$25K. The rate at $100K is often the same as at $500K.
