Some like Pentagon Federal keep 100% of their mortgage loans. That's a nice feature of buying through them, not having your loan sold to random companies from time to time. That leads to them being very conservative with their lending and giving you an enhanced interrogation to get approved though. If every lender operated like them these financial crises wouldn't come as often.

In a way its kind of immaterial if there is a "run" on a credit union. I can't imagine very many members have shares over the insured limits (250k in checking, 250k in savings), so the deposits have to be almost entirely insured. Also all the little old widows whose GM pension gets deposited every month are not gonna organize and pull their money like silicon valley VCs. They could still be insolvent and get federalized or whatever, but the damage to real people should be minimal even in this kind of unlikely scenario.

I'm thinking of those little old widow's kids reminding her that 0.1% on her "savings" account is not keeping up with the price of groceries. If she's not too old to be reasoned with, her money is going to walk, to TreasuryDirect, or at least a CD.

Right, so she walks, and so do a lot of other widows, the credit union becomes insolvent, NCUA comes in and winds it down and makes the other widows whole. Not ideal, but seems fine.
