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.

There are also leverage rules designed to capture assets deemed to pose no credit risk even though …

Karen Petrou: The Fed Just Puts Ribbons on Rags

Four months after announcing plans for minimal changes to its stress tests, the Fed last Thursday screwed up its courage and proposed a couple of them. The remaining, still-small changes will come after the Fed rests up, but none of this seemingly-strenuous effort addresses the fundamental problem with both capital regulation and the testing designed to ensure it suffices: none of these rules make total sense on its own and all of them taken together are a cacophony of competing demands and ongoing collisions with other standards. Prettying up the stress-test rule is thus only putting ribbons on a ragged assemblage of ill-fitting pieces in clashing colors with large, large holes.

Now-ousted VCS Michael Barr promised a “holistic” capital construct during his 2022 confirmation hearings, but he nonetheless clung tightly to one-off rulemakings without any cumulative-impact analysis. Mr. Barr thus opposed last week’s stress-test changes, but for all the wrong reasons. He thought they went too far; in fact, they don’t go anywhere near as far as they could and should.

The new stress-test proposal most substantively says that banks will henceforth be judged by a three-year rolling average of their tested capital levels, rather than on the current, volatile annual schedule. But, averaging numbers that don’t make sense tells one nothing about the utility of each test. Think about a household with two chihuahuas – average dog weight about ten pounds. Next year, a Labrador romps in, and the average goes up, but the yard can still hold three …
