These guys only started all caps tweeting after the bank was closed on Friday. The bank run started on Thursday when $42B (20-30% of all deposits) were withdrawn.
The run they were tweeting about was a wider one on all regional banks. Did not happen at time of their tweets, they were speculating about the future.
Why was it the VCs impacted by the SVB collapse, and not the wider banking world, who stood to lose more, who were loudest to make that claim?
If you're of the opinion that their Tweets (ignoring what may or may not have happened in certain private chats leading up to) did not lead to the public start of SVB's bank run, maybe? How much pressure did this add on regulators to act NOW to avert an IMMEDIATE and CATASTROPHIC COLLAPSE?
However, is it really a stretch to say that those Tweets may have downstream effects on other banks?
