Abstract

This paper examines the association between discretionary capital buffers, capital requirements, and risk for European banks. The discretionary buffers are banks' own buffers, or headroom: the difference between reported and required capital. I exploit capital requirements data that banks started to disclose since the release of a 2015 European Banking Authority opinion. Results using detailed SREP and Pillar 2 data of the largest 99 European banks over 2013-2019 show that less headroom is associated with increased bank risk. An additional examination reveals a positive association between headroom and stress test results for banks subjected to the Single Supervisory Mechanism, a result that runs against supervisory requirements.
