It’s not to protect the existing depositors of SVB - but to shore up the stability of the entire banking sector.
It’s important to remember that SVB lobbied hard to gain an exemption from banking stress test regulations. Their “inherently low risk” business clearly wasn’t, and they failed to defend against the inevitability that was the fed going up from the anomalously low rates of the 2010s.
What is the bad behaviour of the depositors? Trusting that their deposits were safe in a bank? This isn’t bad behaviour, the government wants people to think that bank deposits are safe. Safety of bank deposits is really important to the economy.
Yes, it is exactly this bad behavior. The gov has only guaranteed safety up to $250k. Any entity exceeding this limit does so at their own risk. By depositing far above the insured limit, you are allowing that bank to transact with your money. The banks loans it out. So by definition those consumers thay ignored the limits incentivized the bad behavior.
Had this bank started losing customers because they faced insolvency risks, they may have changed their behavior. The market provides a feedback loop.
Actually I think you'll find out if you look at the bank failure list that most deposits are paid out in full even if above the insured limit.
Socialism doesn't mean "when the government does stuff"
