Fed minutes: Some officials keen to end stimulus in 2013 WASHINGTON A majority of Federal Reserve policymakers want to continue extraordinary bond purchases to help boost the U.S. economy at least through the middle of the year, according to minutes from the Fed's last meeting released Wednesday. But many members indicated they want to slow and end the program before the end of the year, as long as the job market and economy show sustained improvement. The Fed's purchases of about $85 billion a month in Treasury and mortgage bonds are intended to lower long-term interest rates and encourage more borrowing and spending. Fed's William Dudley on the economy's strength "One gets the sense that many Fed policymakers are anxious to start paring back the size of the ... purchases as soon as the data allow," Dana Saporta, an economist at Credit Suisse, said in a note to clients. Still, a weak employment report released Friday is likely to make policymakers even more supportive of keeping the measures in place for the foreseeable future. Many of the Fed's members want to see sustained improvement in the job market - from a wide range of economic indicators - before making any decision to reduce the pace of purchases, according to the minutes. The minutes showed a wide array of opinions and criteria for when to end the bond purchases, which have boosted the Fed's balance sheet to $3.2 trillion. A few members want to end "relatively soon" the bond-purchase program. Those members say the costs likely outweigh the benefits. A few others saw the risks as increasing quickly and said the purchases would likely need to be reduced "before long." Many members said an improved job market could lead them to slow purchases within a few months, and a few said economic conditions would likely justify continuing the program until late this year.
