I don’t agree he caused SVB, he had to raise rates IMO. I think he was too slow with rates, and perhaps too high at the end, but SVB failed because they didn’t manage their bond portfolio well, and they had a customer base that pulled out their money quickly at the slightest whiff of a problem.
Like you I do believe a large measure of inflation was supply chain, but easy money has to end in times of inflation. Near zero rates is not historically normal, or in my opinion good.
