The Fed said it would buy
mortgage-backed securities, or MBS, for an indefinite period to bolster the
economy. That could spell an opportunity for investors—and might warrant
stocking up on funds that hold the securities, say analysts.
While "QE3" was anticipated,
the particulars of the program were something new. Instead of committing to buy
a fixed amount of Treasury debt—as it did when announcing QE2 in November
2010—the Fed left this round of easing open-ended.
The Fed says it plans each month to buy
$40 billion of agency mortgage-backed securities, which are supported by
government-sponsored enterprises such as Fannie
Mae and Freddie Mac . The Fed says the buying will
continue until the labor market improves substantially.
But because it is unclear how long the
Fed will continue its bond-purchasing program, most segments of the mortgage
market seem to have priced in only about a year's worth of Fed purchases, says
Steven Abrahams, head of MBS and securitization research at Deutsche Bank.
The mortgage market also will be
hypersensitive to changes in the labor market, says Mr. Abrahams. When
unemployment claims or payrolls reports are unexpectedly weak, traders will
expect the Fed's bond-buying program to continue longer, which will push
mortgage bond prices up, he says. Prices could fall after strong reports. (Bond
yields move in the opposite direction of prices.)
