Regulators seized control of Signature Bank ($SBNY@US) on Sunday, one of the main banks for cryptocurrency companies. They also announced emergency measures to guarantee all deposits of SVB, among others, in an effort to ease fears after the collapse of Silicon Valley Bank. A senior Treasury official said the steps didn’t constitute a bailout because stock and bondholders in SVB and Signature wouldn’t be protected. The Fed and Treasury separately said they would use emergency-lending authorities to meet the demand for bank withdrawals. Officials designated SVB and Signature Bank as a systemic risk to the financial system, giving regulators the ability to guarantee uninsured deposits.
