华盛顿(CNFIN.COM/ XINHUA08.COM)--美国联邦储备委员会17日宣布，从10月起将月度资产购买规模继续削减100亿美元，从此前的250亿美元降至150亿美元，并将在10月底的货币政策例会结束资产购买计划。
美联储当天在结束货币政策例会后发表声明说，7月以来的数据显示美国经济继续温和扩张，就业市场进一步改善，但一系列就业指标显示劳动力资源仍然远未被充分利用。美国家庭开支温和增长，企业固定投资增加，但房地产市场复苏仍然缓慢。此外，美国通胀水平一直低于美联储2%的长期目标，但长期通胀预期保持稳定。
美联储决定，从10月起将长期国债的月度购买规模从150亿美元降至100亿美元，将抵押贷款支持证券的月度购买规模从100亿美元降至50亿美元。这样，美联储月度资产购买规模将从此前的250亿美元缩减至150亿美元。
美联储表示，如果未来的信息大体符合美联储对于就业市场继续改善和通胀水平朝长期目标靠近的预期，美联储将在10月底的货币政策例会结束资产购买计划。美联储重申，在结束资产购买计划之后，仍有必要把联邦基金利率(即商业银行间隔夜拆借利率)接近于零的水平保持相当一段时间。
此外，美联储当天公布季度经济预测，将今年美国经济增长预期从此前预计的2.1%至2.3%小幅下调至2.0%至2.2%。
随着近期美国经济重拾复苏势头，美联储内部正就何时启动加息进行辩论，多数市场人士预计美联储将于明年年中启动加息。(完)

For immediate release
Information received since the Federal Open Market Committee met in July suggests that economic activity is expanding at a moderate pace. On balance, labor market conditions improved somewhat further; however, the unemployment rate is little changed and a range of labor market indicators suggests that there remains significant underutilization of labor resources. Household spending appears to be rising moderately and business fixed investment is advancing, while the recovery in the housing sector remains slow. Fiscal policy is restraining economic growth, although the extent of restraint is diminishing. Inflation has been running below the Committee's longer-run objective. Longer-term inflation expectations have remained stable.
Consistent with its statutory mandate, the Committee seeks to foster maximum employment and price stability. The Committee expects that, with appropriate policy accommodation, economic activity will expand at a moderate pace, with labor market indicators and inflation moving toward levels the Committee judges consistent with its dual mandate. The Committee sees the risks to the outlook for economic activity and the labor market as nearly balanced and judges that the likelihood of inflation running persistently below 2 percent has diminished somewhat since early this year.
The Committee currently judges that there is sufficient underlying strength in the broader economy to support ongoing improvement in labor market conditions. In light of the cumulative progress toward maximum employment and the improvement in the outlook for labor market conditions since the inception of the current asset purchase program, the Committee decided to make a further measured reduction in the pace of its asset purchases. Beginning in October, the Committee will add to its holdings of agency mortgage-backed securities at a pace of $5 billion per month rather than $10 billion per month, and will add to its holdings of longer-term Treasury securities at a pace of $10 billion per month rather than $15 billion per month. The Committee is maintaining its existing policy of reinvesting principal payments from its holdings of agency debt and agency mortgage-backed securities in agency mortgage-backed securities and of rolling over maturing Treasury securities at auction. The Committee's sizable and still-increasing holdings of longer-term securities should maintain downward pressure on longer-term interest rates, support mortgage markets, and help to make broader financial conditions more accommodative, which in turn should promote a stronger economic recovery and help to ensure that inflation, over time, is at the rate most consistent with the Committee's dual mandate.
The Committee will closely monitor incoming information on economic and financial developments in coming months and will continue its purchases of Treasury and agency mortgage-backed securities, and employ its other policy tools as appropriate, until the outlook for the labor market has improved substantially in a context of price stability. If incoming information broadly supports the Committee's expectation of ongoing improvement in labor market conditions and inflation moving back toward its longer-run objective, the Committee will end its current program of asset purchases at its next meeting. However, asset purchases are not on a preset course, and the Committee's decisions about their pace will remain contingent on the Committee's outlook for the labor market and inflation as well as its assessment of the likely efficacy and costs of such purchases.
To support continued progress toward maximum employment and price stability, the Committee today reaffirmed its view that a highly accommodative stance of monetary policy remains appropriate. In determining how long to maintain the current 0 to 1/4 percent target range for the federal funds rate, the Committee will assess progress--both realized and expected--toward its objectives of maximum employment and 2 percent inflation. This assessment will take into account a wide range of information, including measures of labor market conditions, indicators of inflation pressures and inflation expectations, and readings on financial developments. The Committee continues to anticipate, based on its assessment of these factors, that it likely will be appropriate to maintain the current target range for the federal funds rate for a considerable time after the asset purchase program ends, especially if projected inflation continues to run below the Committee's 2 percent longer-run goal, and provided that longer-term inflation expectations remain well anchored.
When the Committee decides to begin to remove policy accommodation, it will take a balanced approach consistent with its longer-run goals of maximum employment and inflation of 2 percent. The Committee currently anticipates that, even after employment and inflation are near mandate-consistent levels, economic conditions may, for some time, warrant keeping the target federal funds rate below levels the Committee views as normal in the longer run.
Voting for the FOMC monetary policy action were: Janet L. Yellen, Chair; William C. Dudley, Vice Chairman; Lael Brainard; Stanley Fischer; Narayana Kocherlakota; Loretta J. Mester; Jerome H. Powell; and Daniel K. Tarullo. Voting against the action were Richard W. Fisher and Charles I. Plosser. President Fisher believed that the continued strengthening of the real economy, improved outlook for labor utilization and for general price stability, and continued signs of financial market excess, will likely warrant an earlier reduction in monetary accommodation than is suggested by the Committee's stated forward guidance. President Plosser objected to the guidance indicating that it likely will be appropriate to maintain the current target range for the federal funds rate for "a considerable time after the asset purchase program ends," because such language is time dependent and does not reflect the considerable economic progress that has been made toward the Committee's goals.
