Securities and Exchange Commission chair Gary Gensler expressed concern 14 June that efforts in Congress to write legislation for the cryptocurrency industry could compromise regulations that govern the broader capital markets.

Asked about a bill introduced last week by senators Cynthia Lummis and Kirsten Gillibrand, Gensler initially demurred, saying he would prefer to discuss the proposed legislation with the senators. But he then suggested that legislative changes targeting cryptocurrencies could have implications for stock exchanges or mutual funds.
