Treasury Real Yield Curve Rates. These rates are commonly referred to as "Real Constant Maturity Treasury" rates, or R-CMTs. Real yields on Treasury TIPS (Treasury Inflation Protected Securities) at "constant maturity" are interpolated by the U.S. Treasury from Treasury's daily real yield curve. The Treasury real yield curve is based on closing real bid yields on existing TIPS with remaining terms to maturity of approximately 20 years and less. These real market yields are calculated from composites of quotations obtained by the Federal Reserve Bank of New York. The real yield values are read from the real yield curve at fixed maturities, currently 5, 7, 10 and 20 years. This method provides a real yield for a 7 year maturity, for example, even if no outstanding security has exactly 7 years remaining to maturity.

* On July 27, 2004, Treasury sold a new long-term TIP security and expanded this table to include a 20-year Real CMT rate.

Treasury Yield Curve Methodology. The Treasury yield real curve is estimated daily using a cubic spline model. Inputs to the model are bid-side real yields for outstanding TIPS securities.
