For a long time, the similarities between Potential Future Exposure (PFE) and Credit Valuation Adjustment (CVA) calculations have sparked debate over how these two critical metrics should be handled by banks. Should they be calculated within a single unified system, or in two separate systems, one for XVA (a broader term encompassing CVA, DVA, FVA, etc.) and another for PFE? Historically, the industry has leaned toward using separate systems, largely due to legacy and political reasons. However, this consensus appears to be shifting, partly in response to evolving regulatory expectations.
The default of Archegos in March 2021, which led to significant losses at several major international banks, most notably Credit Suisse, prompted regulators to revisit how counterparty credit risk (CCR) is calculated and managed. Initially, regulators such as the ECB and the Federal Reserve proposed new measures and scenarios for CCR. Then, in April 2024, the Basel Committee released a consultative document recommending enhancements to CCR calculations. This was followed by the publication of its final guidelines in January 2025.
In the consultative version, the Basel Committee suggested calculating PFE using techniques like wrong-way risk (WWR) and jumps-at-default—approaches typically found only in advanced XVA systems. Notably, some of this language was revised in the final version of the guidelines.
In this paper, we explore the overlap between PFE and CVA (the core of XVA), review the Basel Committee’s consultative and final documents, and assess whether banks should, and ultimately will, move toward a single unified system for calculating both PFE and XVA.
