Silvergate Capital ( NYSE: SI ) stock jumped 11% in Friday after-hours trading after the digital asset-focused bank said its exposure to insolvent cryptocurrency exchange FTX were less than 10% of its total digital asset deposits totaling $11.9B, adding that its relationship with FTX was limited solely to deposits . Still, shares of the digital asset-focused bank suffered from concerns about its potential links to Sam Bankman-Fried's crumbling crypto empire, which is comprised of FTX and hedge fund Alameda Research. The stock dropped over 34% in the past week. "Silvergate has no outstanding loans to nor investments in FTX, and FTX is not a custodian for Silvergate’s bitcoin-collateralized SEN Leverage loans," said Alan Lane, the lender's CEO. He also noted that its loans collateralized by bitcoin ( BTC-USD ) "have continued to perform as expected with zero losses and no forced liquidations." Earlier this week, (Nov. 9) Wednush warned of Silvergate's possible FTX-linked credit exposure .
