The problem is that any two competitors X and Y, in any field.
If X does not plan for low-probability failure and Y does, then Y will not have the additional inefficiency/overhead and so X will out-compete Y.
If the time frame for low-probability failure is long enough, and if being out-competed means the end of your business, then an efficient market means that risks which typically take longer than time T to manifest will not be handled, where T is the time for X to out-compete Y, given their advantage.

The problem is not restricted to banking.

What's your point? Customers will choose the mix of cost and risk that makes them comfortable.
I guess that my point is that anyone who thinks that a market will give them long-term stable institutions/companies is wrong.
I think that conclusion is likely to be surprising/controversial to some/many people.

Definitely. It's a complex, dynamic system that requires enormous amounts of failure, misattribution and foolish optimism to work.
The beautiful thing is that it turns these human inevitabilities from negatives into positives.
