One of the largest, most influential reinsurance operations in the United States will be getting a new leader.

Swiss Reinsurance Company, Zurich, says Roger W. Ferguson Jr. will be succeeding Jacques Dubois both as chairman of its Swiss Re America Holding Corp. unit and as a member of the parent company’s executive board.

Ferguson, who served as vice chairman of the U.S. Federal Reserve Board from 1999 to April of this year, will be coming aboard in July, and Dubois will be retiring at the end of the year, according to Swiss Re.

Ferguson will be in charge of a large property-casualty reinsurance business and a $130 billion investment portfolio as well as Swiss Re’s U.S. life and health operations, the company says.

Ferguson has doctorate in economics and a law degree from Harvard University. He joined the Fed as a governor in 1997, and he helped lead the Fed’s immediate response to the Sept. 11, 2001, terrorist attacks.
