FRM Part II · FRM Exam Part II · Fundamental Review of the Trading Book

Under the FRTB internal models approach, which risk measure replaced 99% Value-at-Risk as the basis for calculating trading book market risk capital?

FRTB uses expected shortfall at a 97.5% confidence level in place of 99% VaR. ES averages losses in the tail beyond the cutoff, so it captures tail severity and is coherent, whereas VaR ignores losses beyond its threshold.

Explanation

FRTB replaces 99% VaR with expected shortfall calibrated at 97.5% confidence, which captures tail severity beyond the cutoff. Stressed VaR was a Basel 2.5 feature and is replaced, and the 99.9% incremental risk charge was also replaced by the default risk charge.
