If the ruling is based on narrow grounds that the FSOC can readily address, it will have little impact on long-run prospects for U.S. financial stability.

However, if the Court has materially raised the hurdle to SIFI designation—and if its ruling holds up on appeal—“too big to fail” nonbanks could again loom large in future financial crises, making them both more likely and more damaging...
