I don't think this is within the existing authority of the FDIC, or Federal Reserve to do. I'm not an expert, so happy to be corrected, but given where things are currently -- with SBV closed, assets transferred to the Deposit Insurance Bank of Santa Clara -- I believe this would take an act of Congress.
And I sincerely doubt there is appetite in Congress for a bank bailout for Big Tech.
I appreciate that's perhaps how it'll be viewed, but let's be clear here: "big tech" is not being bailed out. Apple, Google, Meta, etc. do not have a substantial portion of their cash in SVB. Sequoia, Andreesen, etc. do not have a substantial portion of their fund in SVB (most of it is kept by their LPs until actually used). Investors of SVB are not being bailed out -- shareholders exit last (as they should).
The people being "bailed out" are the owners and employees of small businesses and startups that, just by nature of having a deposit as SVB, unconsciously acted as a creditor to an institution that had an 'A' credit rating by Moody's, a 'Buy' rating by JPM, and had passed whatever monitoring and risk tolerance requirements put in place by the Fed.
And I sincerely doubt there is appetite in Congress for a bank bailout for Big Tech.
