“There is no such thing as free regulation”
– John Hutton
Starting in May 2012, the Basel Committee on Banking Supervision (BCBS) published several papers on the Fundamental Review of the Trading Book (FRTB) proposing major changes to capital requirements for market risk. In 2015 the FRTB was enhanced with the “FRTB-CVA [credit value adjustment] framework” (BCBS 2015). We will discuss this latest version here. The key issues of the FRTB-CVA framework are as follows.
-
After about 20 years of applying VaR (value-at-risk) with a 99% confidence level and a 10-day horizon, now the expected shortfall (ES) on a 97.5% confidence level for different liquidity time horizons is applied. We will discuss this change in detail below.
-
Six risk types are determined: (1) equity risk (2) interest-rate risk, (3) foreign-exchange risk (FX), (4) counterparty credit spread risk, (5) reference credit spread risk and (6) commodity risk. For each risk type ES (expected shortfall) has to be derived daily on a 97.5% one-tailed confidence level for different time horizons. ES also has to be derived for a period of significant stress.
