Earlier quoted context omitted.
It's coming from the same system that probably led you to work at Startups your whole career. High risk for high reward on a lightly regulated capitalist system. If your CEO or CFO put all the money in one risky bank, it was bad financial management.
It wasn't risky as long as prime rate stayed super low. But that rate has been creeping up for months now. SVB was too small to qualify for risk assessment under the revised banking rules. So they could get away with money in volatile securities that were very interest rate sensitive. That said, SVB seemed very solid until Thursday morning.
That sounds a bit like "it's not risky to driver a motor vehicle as long as you don't get into an accident".
