Banks’ regulatory capital buffer and the business cycle: Evidence for Germany

This paper analyzes the effect of the business cycle on the regulatory capital buffers of German local banks in the period 1993–2004. The capital buffers are found to fluctuate countercyclically over the business cycle. The evidence supports that low-capitalized banks do not catch up with their well-capitalized peers over the observation period and they do not decrease risk-weighted assets during a recession. This finding suggests that their low capitalization does not force them to retreat from lending.
