Average CD Rates vs. Treasury Yields: The CD Rate Gap

Average CD rates today

National averages from the FDIC for deposits under $100,000, as of September 30, 2026, next to the Treasury yield for the same term. Next update expected November 16, 2026.

*No 4-year Treasury exists; the 48-month benchmark averages the 3- and 5-year yields. Rates vary widely by bank: compare any offer with the Treasury yield for the same term.

Key findings

1. Average CDs pay well under half the Treasury yield. The FDIC's national average for a 12-month CD was 1.76% on September 30, 2026, while the 1-year Treasury yielded 4.54%. That's a gap of 2.78 percentage points: savers earned about 39 cents for every dollar of the risk-free rate. On $10,000, that's $176 in a year instead of $454.
2. Locking money up longer pays less, not more. The average 60-month CD paid 1.41%, less than the average 12-month CD, even though the 5-year Treasury yielded 5.09%. The gap is 2.78 points at 12 months and 3.68 points at 60 months. Over five years, $10,000 earns $728 in the average 5-year CD and $2,818 at the 5-year Treasury yield.
3. The average CD hasn't beaten inflation since this data series began. In all 66 monthly readings since February 2021, the average 12-month CD rate was below the annual inflation rate. In September 2026, inflation was 3.74%, which puts the average CD's real return at −1.98 points.
4. CD rates barely followed the Fed, in either direction. From February 2022 to the CD rate's peak in August 2024, the Fed raised its target rate by 5.25 points while the average 12-month CD rose 1.73 points, about 33 cents per dollar of increases. When the Fed then cut by 1.75 points, the average CD fell 0.27 points by December 2025.
5. Savings accounts lag even more. The average savings account paid 0.38%, less than a tenth of the 4.20% yield on a 3-month Treasury bill.

What this means for savers

• Treat the average as a floor, not a target. CD rates vary widely from one institution to the next. The Treasury yield for the same term, in the table above, is a useful yardstick for any offer.
• Taxes widen the gap for many savers. Interest on Treasury bills and notes is exempt from state and local income taxes; CD interest is not.
• Know the trade-offs. CDs at FDIC-insured banks are protected up to $250,000 per depositor, per bank, per ownership category, and cashing out early usually costs a penalty. Treasuries are backed by the U.S. government and can be bought at TreasuryDirect or through a brokerage; if you sell before maturity, the price can be lower than what you paid.
• Longer isn't automatically better. At the average bank, a longer CD doesn't pay a higher rate. Compare each term on its own.

Methodology

CD and savings rates. FDIC national rates for deposits under $100,000, published monthly in the FDIC's National Rates and Rate Caps. Since April 2021 the national rate has been the average of rates paid by all insured depository institutions and credit unions with available data, weighted by each institution's share of domestic deposits. Each release reflects rates on the last business day of the previous month: this edition, published in October 2026, reflects rates on September 30, 2026.

Treasury benchmark. Daily constant-maturity yields from the Federal Reserve's H.15 release, taken on the same date as the FDIC data and matched by term: 3- and 6-month bills, and 1-, 2-, 3- and 5-year notes. There is no 4-year Treasury, so the 48-month benchmark is the average of the 3- and 5-year yields.

Calculations. The gap is the Treasury yield minus the average CD rate, in percentage points. "Cents per $1" is the CD rate divided by the Treasury yield. Dollar amounts assume $10,000 held for the full term, with both rates compounded once a year. Treasury yields are quoted on a semiannual (bond-equivalent) basis, so this simplification slightly understates Treasury earnings and the gap.

Inflation. The year-over-year change in the Consumer Price Index for All Urban Consumers (CPI-U, not seasonally adjusted) for the month of the FDIC data. FRED has no CPI value for October 2025, so that month is left out of the inflation comparison.

Pass-through of Fed moves. The change in the average 12-month CD rate divided by the change in the upper bound of the federal funds target range: from February 28, 2022, before the first increase of the 2022–23 cycle, to the CD rate's peak on August 30, 2024, and from that peak to December 31, 2025, after the last cut of the 2024–25 cycle.
