The conclusion from game theory (specifically Prisoner's Dilemma) is not that only one action is rational. Both cooperation and defection are rational; that's what "dilemma" means. The difference lies in the scope or horizon to which reason is applied. Every time I see someone invoke "rationality" or game theory to justify what is really selfishness, it makes me want to throw up.
Failure was a foregone conclusion non matter what time horizon you wanted to apply.
The bank had wiped its equity before depositors drew on it. It was a matter of time it failed. Its loan portfolio is impaired. Its startups are burning DDA cash without vc funding. The majority of its capital is locked up on long duration bonds.
The bank was bleeding from a thousand cuts. It was put out of misery by a good old run to the head. Eventually some startup was going to try drawing on their checking and it was going to fail.
A bank run is just a symptom of the disease (mismanaged bank risk).
