Major Global Yield Curves Refreshed Daily

Treasury PAR Real Yield Curve Rates

The par real curve, which relates the par real yield on a Treasury Inflation Protected Security (TIPS) to its time to maturity, is based on the closing market bid prices on the most recently auctioned TIPS in the over-the-counter market.

Treasury Bill Rates

Treasury Long-Term Rates and Extrapolation Factors

The US Treasury ceased publication of the 30-year constant maturity series on February 18, 2002 and resumed that series on February 9, 2006. To estimate a 30-year rate during that time frame, this series includes the Treasury 20-year Constant Maturity rate and an “adjustment factor,” which may be added to the 20-year rate to estimate a 30-year rate during the period of time in which Treasury did not issue the 30-year bonds.
