What's happening? I want Greenspan back.

...about bank failures, you may want to give some examples.  The FDIC says bank failures have been declining in the past few years:

How does FDIC determine when to close?

That may close a bank.  FDIC does not have the authority to close a bank, but since they insure deposits they are appointed receiver of the failed bank to liquidate the assets and recover their money. They are primarily closed for either deficient capital, liquidity, or some other unsafe practice.

'branches' for banks.

If you are talking about a bank closing a branch in your town. Or multiple banks doing it. It's because each branch is a cost center and more and more people are using online banking. They don't need to visit the bank itself. Less staff = higher profits. It's also a way to funnel ppl to being okay with eliminating cash. So many of the banks and elites want that to happen asap. It's the easiest way to control the plebs..
