Treasury reset savings bond rates on November 1, and the headline went to Series I bonds: a 5.51% composite rate built from a 1.40% fixed rate and a 4.08% annualized inflation component — a fixed rate that beat the 1.30% most analysts had projected.
Series EE bonds got the quieter line in the same press release. Bonds issued from November 2026 through April 2027 earn a fixed 2.90%, up from 2.40% for the May–October batch. For most buyers, that 2.90% is not the number that determines what the bond pays.
A guarantee that overrides the stated rate
The same release contains a second promise: "At 20 years, the bonds will be worth at least two times their purchase price." TreasuryDirect is more explicit on its EE bond page — if accrued interest falls short of doubling, Treasury makes a one-time adjustment at the 20-year mark to make up the difference.
At 2.90% compounded semiannually, $10,000 grows to about $17,787 in 20 years. The guarantee pays the rest. Treasury adds roughly $2,214, and the bond is worth $20,000.
Doubling in 20 years is an annualized return of 3.53%, not 2.90%. The stated rate is a floor underneath a floor — it only sets what Treasury has to top up.
The adjustment lands in one month
Here is the part that costs people money. The top-up is not spread across the holding period. It arrives at month 240.
At 19.5 years, that same $10,000 bond is worth about $17,532. Six months later it is worth $20,000. Nearly 25% of the entire 20-year gain shows up in the final six-month accrual period. Cash out in year 19 — a perfectly reasonable thing to do with a bond you've held two decades — and you keep the accrued interest and none of the guarantee.
The other timing rules are mild by comparison: EE bonds can't be redeemed for 12 months, and redeeming before five years forfeits the last three months of interest. Years 21 through 30 are the real wildcard, since Treasury may change the rate or the earning method for that final decade. TreasuryDirect says so plainly, and notes you can cash the bond at 20 years if you don't like the new terms. Month 240 is both the payoff and the natural exit.
What 3.53% is competing against
A 20-year Treasury note yielded about 5.35% on November 3, per Trading Economics — roughly 180 basis points more than the EE guarantee, though with price risk if you sell early. The EE bond has no price risk; it has a two-decade commitment instead.
Against the I bond, the comparison is cleaner. EE's 3.53% is nominal. The I bond's 1.40% fixed rate sits on top of inflation. EE wins only if inflation averages below about 2.1% over the next 20 years. The I bond's current inflation component is running at 4.08% annualized.
Where it fits in a retirement plan
- Match the lock to the horizon. The guarantee requires 20 years. That is a plausible commitment at 45 and a poor one at 70.
- You choose the tax year. EE interest is federally taxable but deferrable until you cash the bond — and it is exempt from state and local income tax. A bond redeemed in a gap year between retiring and starting Social Security or RMDs lands 20 years of interest in a low-bracket year.
- Deferral has an expiration date. At 30 years the bond stops earning and the interest becomes reportable whether you redeem or not. Treasury issues a Form 1099-INT.
- The limits are per series. $10,000 per Social Security number per calendar year in EE bonds, and a separate $10,000 in I bonds — $20,000 combined.
