The New York Department of Financial Services seized crypto-friendly Signature Bank in order "to protect depositors," the state banking regulator said in a Sunday night announcement.

In an action similar to what California's banking regulator performed on Friday in reaction to an extraordinary run on deposits at Silicon Valley Bank, the Federal Deposit Insurance Corp. was also appointed receiver of the New York-based bank.

In a separate statement, U.S. federal bank regulators guaranteed full return of Silicon Valley and Signature Bank customer deposits. 

"All depositors of this institution will be made whole. As with the resolution of Silicon Valley Bank, no losses will be borne by the taxpayer," the Federal Reserve Board, Treasury Department, FDIC said in a joint statement, while guaranteeing that, “No losses will be borne by the taxpayer.” 

Signature and now defunct Silvergate, which decided to wind down operations this week, were top banks used by crypto companies, raising the question of where they’ll be able to turn to next.

Signature had taken steps at the end of last year to bring down the concentration of crypto deposits it held by string a 20% cap.

Signature’s senior management has also been removed and shareholders and certain unsecured debtholders will not be protected, the statement said.
