We estimate the joint term-structure of U.S. Treasury cash and repo rates using daily prices of all outstanding Treasury securities and corresponding special collateral (SC) repo rates. This allows us to derive a risk premium associated to the SC value of Treasuries and quantitatively link this premium to various price anomalies, such as the on-the-run premium. We show that a time-varying SC risk premium can explain between 74%–90% of the on-the-run premium, and is highly correlated with a number of other Treasury market anomalies. This suggests a commonality across these price anomalies, explicitly linked to the SC value of the highest-quality securities—recently-issued U.S. nominal Treasuries.
