The 250k is messaging to minimize moral hazard. You want banks and depositors invested in minimizing their own risk. I'd guess hesitancy to immediately declare full guarantee of funds is also due to these concerns (although there may be other reasons as well). The sweet spot here maximizes the appearance of consequences while minimizing actual fallout.
But now banks know is just a bluff?
It’s a valid Q how saving depositors impacts CFO risk analysis. Hopefully no matter what the outcome this scares everyone into diversification.
