HousingWire reports that Bob Ryan, chief risk officer at the Federal Housing Administration (FHA), has been picked as the acting commissioner of the Department of Housing and Urban Development (HUD).  Outgoing commissioner David Stevens, who had appointed Ryan into the newly created position of risk officer in 2009, will head the Mortgage Bankers Association (MBA).  Having spent 26 years in the mortgage business, Ryan increased FHA’s ability to undertake more intricate data analysis and assess risk.  FHA’s market share increased from three percent in 2005 to 35 percent in 2009.  Congress wants to return more market share to the private sector.
