The biggest bond dealers in the U.S. say the Federal Reserve is poised to start a new round of stimulus, injecting more money into the economy by purchasing mortgage securities instead of Treasuries.

Fed Chairman Ben S. Bernanke and his fellow policy makers, who bought $2.3 trillion of Treasury and mortgage-related bonds between 2008 and June, will start another program next quarter, 16 of the 21 primary dealers of U.S. government securities that trade with the central bank said in a Bloomberg News survey last week. The Fed may buy about $545 billion in home-loan debt, based on the median of the firms that provided estimates.

While mortgage rates are already at about record lows, housing continues to constrain the economy, with the National Association of Realtors saying in Washington last week that the median price of U.S. existing homes dropped 4.7 percent in October from a year ago. Borrowers with a 30-year conventional mortgage would save $40 billion to $50 billion annually in aggregate if they could all refinance into a new loan with a 3.75 percent rate, according to JPMorgan Chase & Co.

"We need to see a bottom in home prices," said Shyam Rajan, an interest-rate strategist in New York at Bank of America Corp., a primary dealer, in a Nov. 22 telephone interview. "These are not numbers that are going to get down your unemployment rate," which has held at or above 9 percent every month except two since May 2009, he said.

David Fuller's view This certainly looks like QE3 to me. Wall Street may like it but there must be a serious risk that Mr Bernanke's deflation fighting measures are increasing the longer-term risk of uncomfortably higher inflation.
