1 Year Treasury (CMT) Definition

What Is the 1 Year Constant Maturing Treasury Rate?

This index is an average yield on United States Treasury securities adjusted to a constant maturity of 1 year, as made available by the Federal Reserve Board.  Yields are interpolated by the United States Treasury from the daily yield curve. This curve, which relates the yield on a security to its time to maturity, is based on the closing market bid yields on actively traded Treasury securities in the over-the-counter market.

(Note:  This rate is updated after the Federal Reserve releases its previous months data on the first Monday or first business day of each month.)
