Front-End Rates and Long-End Relative Value in the U.S. Treasury Curve (Research Square)

Summary

• A lagged reference gap lowers twenty-observation official-curve forecast mean squared error (MSE) by 3.48 percent.p.2
• On October 16, 2026, the official constant-maturity curve was 3.03 basis points flatter than the continuous-forward reference.p.3
• For 1,164 positive-gap official-CMT origins from 2015 onward, an equal-gross-DV01 steepener had a payoff standard deviation of 3.51 basis points, compared with 22.14 for an outright two-year long.p.3

Key insights

1. Front-end rate conditions establish a conditional relative-value benchmark for ten-year versus thirty-year Treasury spreads.p.2
2. Frozen-reference accounting demonstrates that daily alignment closure is primarily driven by spread adjustment rather than reference parameter shifts.p.9
3. An equal-gross-DV01 steepener provides relative protection during rising-rate episodes by sacrificing directional rally participation to reduce drawdown size.p.11
4. Routine scheduled auction quantities do not absorb the conditional curve adjustment relationship.p.18
