Update: Another bank was shut down, this time by the New York Department of Financial Services on Sunday; the agency appointed the FDIC as receiver. New York's Signature Bank was a player in the crypto space, which one commentator labeled akin to a video game. Federal bank regulators issued a joint statement warning of the dangers in crypto finance. Among the laundry list of shady practices are: misrepresentations and misleading disclosures by crypto asset companies, trading on open access public networks without adequate governance, and significant volatility of crypto assets including coins.
SNB specialized as the go-to bank for tech and crypto start-ups. It survived the DotCom bust of 2002, but this bubble was bigger. Its stock price hit a "hallucinogenic peak" in November 2022 of over $700 per share.
Tech start-ups are intense cash drains. When the bank began to back away from lending to these risky ventures, the drain on its accounts continued while deposits dried up. The bank had to sell assets to meet those withdrawals. When it sold $21 billion in bonds, SNB lost $1.8 billion due to falling market value caused by rising bond yields. (Remember bond yields move inversely to price.) Interestingly, SVB Financial, which owns the bank, was rated "investment grade" just prior to the collapse. On Wednesday Moody's rated it A3; even after the bank announced its bond sale loss, Moody's only reduced its bond rating to Baa1, still investment grade. Lesson: do not rely entirely on bond rating scores to make investments. There is market pressure to keep bond rating high.
There are rumors that SNB warned some investors to yank their funds before the bank became insolvent since FDIC insurance is limited to the first $250,000.
The FDIC announced that the bank-in-receivership will resume operations on Monday, and that cash will be available to customers. Right now the FDIC does not look like it will suffer a loss for the takeover, as there are sufficient bank assets to pay insured accounts and partially pay sonme uninsured depositors. Bank shareholders, as usual are SOL. Blame it on the Great Techno Bust, or tulips take your pick.
