Your funds might be in a HYSA but the bank holding them probably has them in stocks and bonds.
So if the stocks fall enough you won’t have your money anyways.
Now you could say you want to hold onto cash instead, but the only fix for the banks not having money is to print money which makes cash worth less.
Okay but what if you held gold or other minerals. Well the value of those comes from the perception that they could be used to trade when other things fail, but even if milk is $500 a gallon no grocery store is going to take gold as it isn’t able to be insured and tracked. So the value of gold also will drop as it can’t actually be used for goods and services.
So basically you can’t isolate yourself and protect yourself from societies stupidity. Its all a gamble and maybe your option works out or maybe it doesn’t but there isn’t a clear way to avoid the problem.
You are supposed to, but it is only insured to 250k. That might seem like a decent amount but if you suffer inflation and a government that is inclined to decrease FDIC rather than increase, you might end up not really getting much value out of that cash.
250k is not a very big nest egg for retirement.
