At the end of 2022, the bank had total assets of US$110.4 billion and deposits of $82.6 billion; as of 2021, it had loans of $65.25 billion. Signature Bank was founded in 2001 by former executives and employees of Republic National Bank of New York after its purchase by HSBC. It focused on wealthy clients and built personal relationships with them. For most of its history, it had offices only in the New York City area. In the late 2010s, it began to expand geographically and in terms of services, though it was most noted for its 2018 decision to open itself to the cryptocurrency industry. By 2021, cryptocurrency businesses had represented 30 percent of its deposits. Wikipedia
