The 17 US banks that have failed this year (plus two corporate credit unions - that is credit unions for corporations) have all been pretty small outfits, relatively speaking. The US banking system is set up for some banking failures on an ongoing basis, in-keeping with the high-risk, high-reward nature of the system. As the story goes.
Even during the good years, a number of banks would generally fail.
The problem in the US isn't with the banks that have failed so far this year, they've been resolved pretty quickly and painlessly from what I've seen - you know about the
FDIC, right?
No, the problem is with the banks they haven't allowed to fail by govt fiat.
With proper regulation would those banks be healthy? Probably. Smaller? Definitely. Would the US have had any/much growth since the collapse and bailout of Long Term Capital Management, maybe even go back to the S&Ls, without the merger and deregulation binge? Doubtful. Certainly nowhere near what was had. Including tech revolutions.
