By CHRISTOPHER S. RUGABERWASHINGTON (AP) â¿¿ 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 eventually 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. The minutes of the Fed's March 19-20 meeting were released at 9 a.m. EDT â¿¿ five hours earlier than planned â¿¿ after the Fed said it inadvertently sent them a day earlier to congressional staffers and lobbyists. The more than 100 recipients also included employees at JPMorgan Chase, Goldman Sachs Group, Wells Fargo and other large banks , according to a list of email addresses released later in the day by the Fed. "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. The report showed employers added just 88,000 net jobs last month. That was the fewest in nine months and much lower than the average of 220,000 jobs a month created from November through February. The unemployment rate dropped to a four-year low of 7.6 percent last month. However, the rate fell only because more people stopped looking for work and were no longer counted as unemployed.
