Strengthening and Streamlining Bank Capital Regulation. Robin Greenwood, Samuel Hanson, Jeremy Stein, Adi Sunderam, August 2017, Paper, “We propose three core principles that should inform the design of bank capital regulation. First, wherever possible, multiple constraints on the minimum level of equity capital should be consolidated into a single constraint. This helps to avoid a distortionary situation where different constraints bind for different banks performing the same activity. Second, while a regulatory framework that relies primarily on minimum capital ratios is appropriate for normal times, such a framework is inadequate in the wake of a large negative shock to the system. Following an adverse shock, it becomes critical to emphasize dynamic resilience, which involves forcing banks to actively recapitalize—i.e. regulation needs to focus on getting banks to raise new dollars of equity capital, rather than just maintaining their capital ratios.Link
