The U.S. Department of the Treasury updated its Daily Treasury Par Yield Curve rates for 2026. The series, commonly called Constant Maturity Treasury rates, covers 1-month, 1.5-month, 2-month, 3-month, 4-month, 6-month, 1-year, 2-year, 3-year, 5-year, 7-year, 10-year, 20-year and 30-year maturities. The data is associated with the Office of Debt Management and the Federal Reserve Bank of New York. The rates are estimated daily using a monotone convex spline method, which replaced the quasi-cubic Hermite spline method on December 6, 2021. The estimates use closing market bid-side prices or quotations, rather than actual transactions, obtained by the Federal Reserve Bank of New York at or near 3:30 p.m. on each trading day. Nominal Constant Maturity Treasury series are floored at zero if negative yields occur. Extrapolation-factor, bank-discount and coupon-equivalent columns are shown as N/A for the dates below.
Across the January and February observations, the 10-year rate ranged from 4.15% on January 7 to 4.30% on January 20. The 30-year rate ranged from 4.79% on January 14 and January 15 to 4.91% on January 20 and February 4. The 1-month rate ranged from 3.70% to 3.79%, the 2-year rate from 3.46% to 3.61%, the 5-year rate from 3.70% to 3.86%, and the 7-year rate from 3.91% to 4.08%.
