The Treasury's par yield curve: for each maturity, the yield of a security trading at par, estimated from the closing market bid prices of the most recently auctioned securities (the Treasury's Daily Treasury Par Yield Curve Rates). These are the constant-maturity yields the Treasury publishes each business day, in percent per year.

The three curves open on the latest date, a week earlier and a month earlier. Pick any dates with the calendars; a date with no curve (a weekend or holiday) shows the previous business day's curve, and the legend names the date used. Not every maturity exists on every date: the 2-month began in 2018, the 4-month in 2022 and the 1.5-month in 2025; the 20-year is missing from 1987 to 1993.
