The head of the U.S. securities industry lobbyist, the Securities Industry and Financial Markets Association (SIFMA), is heading back to JPMorgan Chase and Co.

JPMorgan announced Tuesday that Tim Ryan, SIFMA’s CEO since 2009, is to re-join the firm as global head of regulatory strategy and policy. Before heading to SIFMA, Ryan was vice chairman of investment banking for financial institutions and governments at JPMorgan. Before that, he was director of the Office of Thrift Supervision, a partner in a Washington, D.C. law firm, and solicitor of labor at the U.S. Department of Labor.

Ryan will depart SIFMA on February 23. In the meantime, SIFMA’s executive committee has appointed Kenneth Bentsen, Jr., executive vice president, public policy and advocacy, as acting president and CEO (effective, Feb. 23), while the board begins a search for a permanent replacement.

“More than at any time in our history, regulatory strategy and policies around the world are affecting our business and how we serve clients. Tim has both a deep knowledge of these policies and the government representatives formulating them, and also knows our businesses and executives extremely well from his 16 years at the firm,” said Matt Zames, co-chief operating officer for JPMorgan Chase.
