I'm not sure if that's what the previous poster was referring to, but before SVB officially collapsed it tried to get an emergency loan but failed because the system for such emergency loans is slower than the systems its clients could use to transfer money out.
> And yet! Man! What the heck! A lot has been written about how SVB was a bank run for a speedier, modern age. Instead of hearing a rumor at the coffee shop and running down to the bank branch to wait on line to withdraw your money, now you can hear a rumor on Twitter or the group chat and use an app to withdraw money instantly. A tech-friendly bank with a highly digitally connected set of depositors can lose 25% of its deposits in hours, which did not seem conceivable in previous eras of bank runs.
But the other part of the problem is that, while depositors can panic faster and banks can give them their money faster, the lender-of-last-resort system on which all of this relies is still stuck in a slower, more leisurely era. “When the user interface improves faster than the core system, it means customers can act faster than the bank can react,” wrote Byrne Hobart. You can panic in an instant and withdraw your money with an app, but the bank can’t get more money without a series of phone calls and test trades that can only happen during regular business hours. And so sometimes a bank that theoretically has a lot of liquidity can just run out of cash.
