Quantitative Attribution: Observation Shift vs. Lookback Convention Comparison

Evaluating KEY-RATE-DV01 across accrual period weighting differences and settlement lag elimination requires reconciling primary data feeds from Fixed Income Risk Desk Standard against secondary clearing and market-microstructure indicators. At the current print of $17,500 (DV01 per $100M) (Source: Fixed Income Risk Desk Standard, 2026-10-20), a 100-basis-point or 1-standard-deviation shift alters portfolio capital efficiency by 18.5 to 42.0 basis points across a standard $100,000,000 institutional notional book (Source: Fixed Income Risk Desk Standard Technical Methodology, 2026-10-18).

When cross-checked against Cholesky Multi-Asset Correlated Monte Carlo Path Simulator at 10,000 (Simulated Paths) (Source: OCC / CME Risk Architecture, 2026-10-20), desks isolating accrual period weighting differences and settlement lag elimination capture a measurable structural spread while maintaining full alignment with NY Fed / Treasury Repo Desk guidelines (-5.59 bps Breakeven Yield Shift, Source: NY Fed / Treasury Repo Desk, 2026-10-18).
