RE:RE:VIX not spiking This is very true, but we all know the media needs to always have a seed of worry in their reporting or else they wouldn't be needed. Like every movie or book needs a foe or villian, otherwise it's just not entertaining or newsworthy.
Getting back to a "bank run", SVB is a reminder of just how close we always are to one. With digital banking today, it's very possible to have a bank's deposits liquidated in mere hours. It will likely never happen to the largest banks, but... it could. And that's the discussion these talking heads are on about.
As far as protecting all deposits for all banks... can't happen. Our capitalist society is designed to lend out more than what's in the till.
