Updated every business day
Daily U.S. Treasury rates — Sep 21, 2026
The rates the Treasury published at the close of Sep 21, 2026: what bills were sold at, what the yield curve looks like across every maturity, and what TIPS yield after inflation. These are today's market yields — not the average rate the government pays on debt it issued years ago.
The three daily series
Each has a page of its own with history back to Jan 2, 2019, a downloadable CSV, and an explanation of what the numbers mean.
| Series | What it answers | Latest |
|---|---|---|
| Treasury bill rates | What short-term bills — 4 weeks to 52 weeks — were sold at today | 4.12% 13-week |
| Treasury yield curve | Today's par yield at every maturity from 1 month to 30 years | 4.96% 10-year |
| TIPS real yields | What inflation-protected securities yield after inflation, and the breakeven rate implied | 2.62% 10-year |

Why these differ from the average rates on this site
Most of Treasury Rate Watch tracks the average interest rate the Treasury actually pays on debt already outstanding. That average moves slowly, because it blends securities issued across many years and many rate environments — a 30-year bond sold in 2015 still pays its 2015 coupon.
The figures on this page are the opposite: today's yields, set by today's market and today's auctions. When rates rise, these move immediately while the average creeps up only as old securities mature and are refinanced. Reading the two side by side is the clearest way to see how much of a rate change has actually reached the government's interest bill — and how much is still to come.
Both come from the U.S. Treasury and both are in the public domain. The daily series are published each business day at about 3:30 p.m. Eastern; this site rebuilds after the close.
