Method
Source: U.S. Department of the Treasury, Daily Treasury Par Yield Curve Rates (XML feed), one record per trading day since 1990, values in percent as published. Par yields are read from the Treasury's own curve; nothing is interpolated here. Spreads are simple differences in percentage points, shown in basis points. The 1-month, 2-month and 4-month tenors exist only for recent years. Every number links to its filed record. Updated each trading day after the Treasury publishes.
