Credit Benchmark revolutionizes internal models

Pools data to improve accuracy and transparency; could disrupt ratings industry.

The internal-ratings based approach for banks to quantify capital for credit risk – a framework deployed by over 100 banks, from Europe to China and Australia – is in crisis. While the Fed has been consistently sceptical of it, European regulators at the Basel level have adopted an ambivalent posture by first encouraging lenders to adopt it, only to then sound the alarm over inconsistences in risk weights.

In 2013, the European Union adopted the Capital Requirements Directive, which sought to reduce systemic reliance on credit ratings by encouraging banks to calculate their own ratings; and to make bank-capital more risk-sensitive, letting lenders use these calculations in their own risk-management or economic capital models. So while the IRB approach was developed for large, internationally active banks by Basel in the early 2000s, the CRD opened it up for use by all banks in Europe.
