Karen Petrou: How to Fix Regulatory Capital? Think Big, Go Simple, Get Tough
Anyone who was surprised by Miki Bowman’s ambitious agenda hasn’t been paying attention. The new vice chair for supervision on Friday reiterated much she’s said before about supervision and regulation, now also saying more specifically what she’ll do about it given that she’s in a position to do it. Much in her plan is heartening, but one proposal is break taking in both its simplicity and importance: Ms. Bowman wants to make the complex of big-bank capital rules make sense as a whole. Former Vice Chair Barr promised to do this when he was confirmed, but he instead proposed only to complicate the capital construct. Ms. Bowman might just put it right.
As we laid out when Mr. Barr promised a “holistic” capital policy, the current approach pulls in at least three directions, and that’s before one starts thinking about unintended consequences related to liquidity and interest-rate risk. First, there are the risk-based capital (RBC) standards designed to capture the credit risk of every asset and exposure, sometimes more than once based on which numbers come out how. Not content with that much complexity, Mr. Barr and other regulators in 2023 proposed a “dual-stack” approach to credit risk largely because, we concluded, they couldn’t make up their minds which one was right. Then there are standards governing market and operational risk – some forward-looking, some retrospective, and some stuck in the middle distance.
