Huobi said on Tuesday it had withdrawn all its funds out of failed New York-based Signature Bank and crypto-focused bank Silvergate Capital Corp, and the exchange's customers funds remain unaffected.

"Huobi previously had a bank account with Silvergate, but all assets were transferred out some time ago and there is no financial partnership currently," a Huobi's spokesperson said in an email reply to Reuters' enquiry.

Funds that had been placed with Signature were also withdrawn and sent to other financial institutions, the spokesperson added.

State regulators closed Signature on Sunday, the third largest failure in U.S. banking history, while Silvergate last week disclosed plans to wind down operations and voluntarily liquidate.

Huobi's adviser Justin Sun, who is also the founder of blockchain platform Tron, said the exchange business was not affected by their recent closures. Sun had said previously that Huobi Global was applying for a virtual asset service providers licence in Hong Kong.

Separately, a spokesperson for another crypto exchange, OKX, told Reuters that it did not have exposure to Signature or Silvergate. (Reporting by Georgina Lee; Editing by Jamie Freed)
