HMM: Why regulators seized Signature Bank in third-biggest bank failure in U.S. history.

The sudden move shocked executives of Signature Bank, a New York-based institution with deep ties to the real estate and legal industries, said board member and former U.S. Rep. Barney Frank. Signature had 40 branches, assets of $110.36 billion and deposits of $88.59 billion at the end of 2022, according to a regulatory filing.

“We had no indication of problems until we got a deposit run late Friday, which was purely contagion from SVB,” Frank told CNBC in a phone interview.

According to Frank, Signature executives explored “all avenues” to shore up its situation, including finding more capital and gauging interest from potential acquirers. The deposit exodus had slowed by Sunday, he said, and executives believed they had stabilized the situation.

Instead, Signature’s top managers have been summarily removed and the bank was shuttered Sunday.

For his part, Frank, who helped draft the landmark Dodd-Frank Act after the 2008 financial crisis, said there was “no real objective reason” that Signature had to be seized.

“I think part of what happened was that regulators wanted to send a very strong anti-crypto message,” Frank said. “We became the poster boy because there was no insolvency based on the fundamentals.”

Frank would obviously want to put the best possible spin on a bank where he sat on the board, but I also wouldn’t put it past the Swamp to do everything in its power to kill off crypto.
