<prompt> Human: I have roughly 2.5mil in cash in 3 high-yield savings. I would like to keep this amount as liquid cash eyeing potential all-cash house purchase, so not interested in funds, etc. Since all three accounts are well over the 250k limit, should I be concerned? Id rather not open up accounts at more banks, but I dont want to feel stupid in case something disastrous happens.  <response>: This is one scenario where i do recommend big banks. 10 years ago the federal government made it abundantly clear that there are certain banks that are too big to fail. That is where i would want my large balances if the SHTF.
