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 …
