No. SVB price crashed 50% in one day and got downrated by Moodys, which exposed a bunch of red flags that would have resulted in a bank run regardless of what VCs said.
The stock crashed because of the initial pseudo bank run due to high interest rates on capital (at least that's the reason given for withdrawals), and the bank's subsequent failure to make up the difference after selling a treasuries portfolio. After which a real bank run occurred. Then the bank started down a path of a more desperate measure, and that's when they were shut down. At least that's what I got from an article.
