(RECAP: The White House has tapped Michael Stegman, a senior Treasury official, to coordinate housing policy across the Obama administration. Mr. Stegman will join the National Economic Council as its main housing adviser this week. Mr. Stegman joined Treasury four years ago and played a key role shaping policy on a range of housing issues, including efforts to broaden access to mortgage credit and to overhaul finance companies Fannie Mae and Freddie Mac. The personnel move suggests major policy shifts on housing aren’t likely in the final 19 months of the administration.)
