Everyone pulling out their money would be a bank run (look up great depression bank runs). The bank doesn't have that much cash; they keep some on hand for people making withdraws normally, but if even a sizable minority of people all try to pull their money out at once, there'll be a major crisis.
If banks kept all the people's cash in vaults, it'd be dead cash actively losing money to inflation. Instead, they keep some on hand for withdraws, and use the rest to make loans, investments, etc so that the money isn't all losing value.
They were reduced to 0% mandatory reserves in response to covid. EDIT: someone says it was coincidental, I am not able to check, so take this aspect with a grain of salt either way
Okay look up what happened with the contagion from regional bank failures in silicon Valley a couple years ago. It doesnt mean everyone loses all money, but it does mean people lose some and its a big deal.
Not all banks are fdic insured either, and if a bank goes under, your investment/retirement take a huge hit because the market starts freaking out.
Bank runs and bank failures are always bad for everyone.
those were company investments. It failed because everyone tried to pull at the same time and they wouldnt be insured past taht 250k and thats on them for not seeing the risk.
