About US Treasury Yield Curve

The US Treasury Yield Curve datasets tracks the yield curve rate from the US Department of the Treasury. The data starts in January 1990 and is delivered on a daily frequency. This dataset is calculated from composites of indicative, bid-side market quotations (not actual transactions) obtained by the Federal Reserve Bank of New York at or near 3:30 PM Eastern Time (ET) each trading day.
