Quantitative Attribution: Standardized Measurement Approach (SMA) & Loss Multiplier Rules

Evaluating GSIB-METHOD2 across Internal Loss Multiplier (ILM = 1.0) neutralization and fee-income bucketing requires reconciling primary data feeds from Federal Reserve Board against secondary clearing and market-microstructure indicators. At the current print of -40 bps (2026 Surcharge Cut) (Source: Federal Reserve Board, 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: Federal Reserve Board Technical Methodology, 2026-10-18).

When cross-checked against Basel III 72.5% Standardized Risk-Weighted Asset (RWA) Output Floor at 72.5% (Minimum RWA Floor) (Source: Basel Committee (BCBS d424), 2026-10-20), desks isolating Internal Loss Multiplier (ILM = 1.0) neutralization and fee-income bucketing capture a measurable structural spread while maintaining full alignment with BIS Basel Committee guidelines (100% 30-Day Stress Minimum, Source: BIS Basel Committee, 2026-10-18).
