If the government is going to guarantee 100% of deposits de facto but not de jure, that seems weird. Perhaps FDIC should guarantee 100% of deposits, but then banking regulations should be designed with that in mind.
Every single CFO and company treasurer knows what the FDIC is and what the limits are. If your one bank collapsing means you can't make payroll, you failed as the financial guide of your company
That said, if we as a society want to protect all deposits that's actually not a terrible idea. We just have to accept what that means, that banks are going to be even more boring institutions than they are, and we have to structure our regulations to make that a feasible arrangement
Dramatically changing the rules of the game in the middle of the play because we don't like the (known ahead of time) outcome of the existing rules is silly and means we basically have no rules
That's a hell of an operational ask for a 2 person startup with (for example, looking at the site we're on) $500k.
I suppose I could take $4m and break that up into 16 different banks, but 16 kyc convos, 16 logins, etc... what a waste of time and energy.
There are services that do this for you. And, maybe it's a risk you're willing to take. Startups are inherently very risky ventures, so out of all the other risks being taken your bank failing is probably low on the risk register in comparison. I think it's ridiculous for established public companies like Roku to get caught flat-footed here, though
At the end of the day it's a known risk, and if you're going to play in the game, you know the rules going into it
