This page provides monthly data & forecasts of the 1-year Treasury bill yield, the effective annualized return rate for Treasury debt with a constant 1-year maturity.

Historical data and forecasted values on this page reflect monthly averages of daily values.

Our market consensus forecast is a daily-updated forecast of key benchmark interest rates. It is generated primarily using yield data and futures market prices, using minimal theoretical assumptions. Forecasts from the model can be interpreted as the median expectation of market participants.

The Treasury yield component of the forecast is generated using three seperate component forecasts:

1. A benchmark rate forecast extracted directly from federal funds rate futures;
2. A credit spread forecast extracted directly from the yield curve;
3. A term premium (usually near zero) calculated using survey data and macroeconomic variables.

Full methodology can be found in the model documentation.

While the model prioritizes consistency with market expectations, its forecast accuracy has historically exceeded that of survey and agency-based forecasts due to its higher update frequency and timeliness. Prior forecast values are available below.

The model is updated daily at 9:35 ET. Key inputs include the prior trading day's futures prices (as of a 3pm ET settlement time); the prior business day's Treasury par yield curves data, obtained from the U.S. Treasury; and the prior business day's effective fed funds rate prices, obtained from the New York Fed.
