In the transition to the Full BA-CVA framework, firms are encouraged to actively manage their risk through eligible credit hedges. However, regulatory capital relief is not granted without scrutiny. The Hedge Mismatch Adjustment (HMA) represents a critical technical component that penalizes basis risk—the inherent uncertainty that arises when a hedging instrument does not perfectly reference the same legal entity as the underlying exposure.

In the "Full Approach" of the Basic Approach for CVA (BA-CVA), the recognition of risk mitigants is a core pillar for capital optimization. Single Name Hedges (SNH) represent the most direct form of protection, allowing firms to offset the credit spread risk of specific counterparties using eligible instruments like Credit Default Swaps (CDS).

Once the Standalone CVA (SCVA) has been calculated for every counterparty in the portfolio, the next stage of the Basic Approach is aggregation. K Reduced represents the aggregate capital requirement for a firm under the assumption that no eligible CVA hedges are recognized. It is the "gross" view of the portfolio's counterparty credit spread risk.
