Overview

Yield on 13-week (3-month) US Treasury bills as quoted on CBOE under the ticker ^IRX. A benchmark for the short-end of the US risk-free curve and the closest market-priced proxy for the Federal Reserve's policy rate.

Interpretation

  • The 13-week bill yield closely tracks the effective fed funds rate, with small deviations during quarter-end or reserves-stress periods.
  • Sharp moves often anticipate Fed rate decisions before they are officially announced.
  • A persistent gap versus macro_fed_funds_rate can signal money-market dislocation or Treasury supply imbalances.

Use Cases

  • Use as a real-time, market-implied gauge of US monetary policy stance.
  • Compare to macro_ust_2y to extract the market's implied policy path over the next 24 months — a useful regime indicator for BTC risk-on/risk-off cycles.
  • Pair with macro_reverse_repo to monitor short-end liquidity conditions.
