Daily Treasury yield curve
The par yield curve published by the U.S. Treasury, as of Jun 22, 2026 — and the spot/zero curve we bootstrap from it. Together they price every security on this site.

How it's used
The Treasury publishes par yields — the coupon a fresh bond at each benchmark maturity would need to trade at exactly 100. To value a bond's individual cash flows we need spot rates, so we bootstrap a zero curve from the par curve, then discount each coupon and the principal at the spot rate for its date.
This is standard matrix pricing. The resulting prices are indicative — model values, not last-traded prices. See Methodology.
