We analyze a sample of 50 large European banks between 2008 and 2012 and document several meaningful findings. First, risk weights are affected by the banks’ size, business model and asset mix. Second, the adoption of internal ratings based (IRB) approaches is (as expected) a powerful driver of bank risk-weighted assets. Third, lower risk weights are positively linked to the banks’ capital cushion. Fourth, IRB adoption is more widespread in countries where supervisory capture is potentially stronger, due to a banking industry that is both larger (compared to GDP) and concentrated. Fifth, regulatory risk weights are not disconnected from market-based measures of bank risk.

The credibility of European banks’ risk-weighted capital: structural differences or national segmentations?

Abstract

We analyze a sample of 50 large European banks between 2008 and 2012 and document several meaningful findings. First, risk weights are affected by the banks’ size, business model and asset mix. Second, the adoption of internal ratings based (IRB) approaches is (as expected) a powerful driver of bank risk-weighted assets. Third, lower risk weights are positively linked to the banks’ capital cushion. Fourth, IRB adoption is more widespread in countries where supervisory capture is potentially stronger, due to a banking industry that is both larger (compared to GDP) and concentrated. Fifth, regulatory risk weights are not disconnected from market-based measures of bank risk.
