Why would customers being made whole (at the cost of wiping out all equity and possibly at some cost to other banks) affect the incentives of banks in this kind of situation? What would banks do differently if account holders could lose everything over $250k? If they are happy to “gamble with 10x leverage” then presumably they don’t care about impact to their customers. If bank management risked jail time that might change incentives but doing that doesn’t seem to require a cost to account holders.
