Wu said it has learned that the U.S. Office of the Comptroller of the Currency (OCC) has issued Interpretive Letter No. 1188, confirming that national banks may, under compliance requirements, engage in "riskless principal" crypto asset transactions. Such transactions refer to banks conducting crypto asset trades simultaneously with two clients in opposite directions under their own name, without holding any crypto asset inventory, acting solely as an intermediary. The OCC emphasized that these activities must be conducted in a safe, sound, and lawful manner.
