Silicon Valley Bank was shuttered by US regulators on Friday after a rush of deposit outflows and a failed effort to raise new capital called into question the future of the tech-focused lender.

With about $209 billion in assets, SVB has become the second-largest bank failure in US history after the 2008 collapse of Washington Mutual, and marks a swift fall from grace for a lender that was valued at more than $44 billion less than 18 months ago.

The Federal Deposit Insurance Corporation, the US regulator that guarantees bank deposits of up to $250,000, said it was closing SVB and that insured depositors would have access to their funds by Monday.
