Customers have not lost any money in SVB yet, just access to money. It's more likely than not that SVB is bought tomorrow, starts running again and even uninsured deposits are covered. SVB ran out of liquidity, the assets did not vanish.

As a general rule, divide some money between multiple banks to avoid counterparty risk.

Same applies to funds, brokers, etc. When Warren Buffet's Berkshire Hathaway bought little bit of SP500 funds for a period, they dividied them equally between VOO and SPY for no other reason.
