SVB’s spectacular implosion began late Wednesday, when it surprised investors with news that it needed to raise $2.25 billion to shore up its balance sheet. Reassurances from SVB’s CEO were not enough to stop the bank run, and depositors withdrew more than $42 billion by the end of the day Thursday, setting the stage for the second-largest bank failure in U.S. history.

The Federal Deposit Insurance Corporation (FDIC) said Friday that it will cover up to $250,000 per depositor and may be able to begin paying those depositors as early as Monday. But the vast majority of SVB’s customers were businesses that had kept far greater uninsured amounts at the bank, which sparked broad concerns about how people will be able to retrieve the rest of their funds.

Yellen said regulators are considering a wide range of options for SVB, including acquisitions.

“This is really a decision for the FDIC, as it decides on what the best course is to resolve this firm,” Yellen said.

Former FDIC Chair Sheila Bair said Sunday that finding a buyer for SVB is “the best outcome.”

“The problem is this was a liquidity failure, it was a bank run, so they didn’t have time to prepare to market the bank,” Bair told NBC’s “Meet the Press.” “They’re having to do that now and playing catch up.”

The fallout of SVB’s collapse could be far-reaching. Startups may be unable to pay employees in the coming days, venture investors may struggle to raise funds, and an already-battered sector could face a deeper malaise.

Bair said the FDIC could help companies with payroll in the case that there’s a systemic risk exception, which would be “an extraordinary procedure.” She said she thinks it is going to be “hard to say that this is systemic in any way.”

Sen. Mark Warner, D-Va., said Sunday that the best outcome would be finding a buyer for SVB before the markets open in Asia. Warner said he is feeling more optimistic that the FDIC will find a solution than he was Saturday afternoon.

 “The shareholders in the bank are going to lose their money, let’s be clear about that. But the depositors can be taken care of,” he told ABC’s “This Week.”
