The CFTC should tap “existing authority to further mitigate potential risks to all customer assets,” Johnson said in a statement on Thursday, citing the cryptocurrency industry drama ignited by the detonation of the FTX exchange. She labeled her statement a “call to action” against digital-assets fraud.

“Liquidity crises and a lack of responsible governance at cryptocurrency exchanges and other prominent crypto-intermediaries have roiled the digital asset ecosystem,” Johnson said. “A series of bankruptcy filings reveals a grim portrait of some of the most egregious corporate governance and risk management failures in recent financial markets history.”

Johnson made the statement as the CFTC sanctioned another crypto industry player: Jeremy Spence, who as “Coin Signals” was convicted of defrauding investors for $5 million and was imprisoned earlier this year on a 42-month sentence.
