Every financial cycle produces a vocabulary of excitement — new instruments, new intermediaries, new reasons why the old constraints no longer apply. And every cycle ends with a quiet migration of deposits toward institutions that never learned the vocabulary.
Boring banking is not the absence of strategy. It is a strategy: match assets to liabilities, know your borrowers, price risk as if you will hold it, and treat funding that can leave in an afternoon as the emergency it is.
