Chart
^IRX is a quoted yield index (not an investable security) that represents the market yield on a 13-week (3‑month) U.S. Treasury bill. It’s commonly used as a proxy for the risk‑free, ultra‑short rate and for benchmarking cash/T-bill returns. Quotes are typically shown in “yield points” (e.g., 36.00 ≈ 3.60% yield).
