If SVB followed any ideology it was libertarianism this is very popular among Tech. Regulations that could have prevented this were rolled back by the Trump administration with the support of several democrats and SVB lobbyists, if SVB were leftist they would be against this and for more regulations for midsize banks.
What really ruined SVB was a lack of regulations like the big banks which they lobbied to remove and holding low yield bonds during a high inflation period.

Essentially SVB had short-term liabilities, or deposits, which it financed with long-term debt — Treasuries and mortgage-backed bonds, as rates went up the value of those treasuries fell drastically.

Also SVB was not a small bank by any metric this was 16th largest bank in the US with more than 200 billion in assets.
