BIS Working Paper 2023 · Cross-sector correlation · Compound macro events
The BIS 2023 Working Paper on compound macro events documents cross-sector NPL correlation of 1.8–2.6× in historical compound events. PHM applied this coefficient to the 2022 European energy crisis lending book and produced compound provision estimates that were subsequently confirmed by Q4 2022 and Q1 2023 ECB SREP results. The mechanism was documented. The coefficient is published. The application to this specific book is PHM's contribution.
