- Since the new Basel III capital requirements for bank's trade exposures to qualifying central counterparty (CCP) were published we built up experience in all calculations in measuring risk exposures and regulatory capital adequacy rules for banks' exposures to CCPs and counterparty credit risk (CCR). These includes all standards set by CPSS-IOSCO. We helped a client in getting compliant by estimating the size of the default/guaranty fund by introducing a novel optimization for the Current Exposure Method (CEM). The CEM is compulsory for CCPs. The end result is that the CCP can estimate the capital exposure for all clearing members and also their capital requirements as prescribed by the Basel III IOSCO regulations.
