When the Fundamental Review of the Trading Book (FRTB) regulation comes into effect in December 2019, market risk capital will increase significantly. Compared to the standard sensitivity-based approach (SBA), the industry expects the internal models approach (IMA) to save an average of 40% in market risk capital. However, desks have to consistently pass two tests in order to get approval for FRTB IMA: back-testing and the P&L attribution test. Especially the P&L attribution test poses a huge challenge.

This white paper explains the P&L attribution test and highlights the practical challenges involved. It gives recommendations on how to overcome these challenges in order to ensure this test is passed consistently.
