The situation was triggered by the government's rate change, but not really caused by it. The government did a normal fiscal policy action and effectively set off a land mine that SVB had set up for itself and its depositors.

The situation was created by SVB irresponsibly locking most of their money into 10-year mortgage-backed securities a couple of years ago when interest rates were historically low, plus the affected startups irresponsibly locking most of their cash into a single bank that took such irresponsible actions, without that one bank being systemically too-big-to-fail from a nationwide policy perspective.

Expecting the government to keep interest rates historically low for another decade or else to bail the bank out is an unreasonable expectation on the part of SVB and the ecosystem that over-relied on it, not the fault of the government.
