This warrant's a little caution, there may well be some negative selection bias here. The banks most likely to go bust are the ones most desperate for cash so they offer the highest interest rates... If it's FDIC insured you are good up to $250k but I don't know exactly how much inconvenience is associated with your bank going bust and potentially collecting FDIC insurance.

This might not be the norm, but when SVB went bust FDIC insured money was paid out in a matter of days.
