扭曲操作

    日期：2011年9月22日

    道琼斯指数：下跌391点，跌幅3.5%

    此次，美联储为促进经济增长所采取的最新举措却遭到质疑，导致股市下跌超过3%。美联储的措施名为“扭曲操作”，即卖出价值4,000亿美元的短期国债，同时购买长期国债。此举旨在压低长期利率，降低企业与消费者的借贷成本。美国央行在其声明中悲观地表示：“经济前景正面临着重大的下行风险，包括全球金融市场正处于紧张状况。”

    该政策（将持续至2012年年中）虽然成功压低了长期利率，但它对经济反弹并未产生显著效果。

Operation Twist

    Date: September 22, 2011

    Dow: -391, down 3.5%

    A new effort by the Federal Reserve to boost the economy was met with skepticism, sending stocks down more than 3%. The Fed's policy, "Operation Twist," involves selling $400 billion in short-term Treasuries in exchange for long-term Treasuries. The goal is to drive long-term rates down, making it cheaper for businesses and consumers to borrow. The central bank was bleakly enthusiastic in its statement, saying, "there are significant downside risks to the economic outlook, including strains in global financial markets."

    The policy, which will remain in place until mid-2012, has succeeded at lowering long-term rates, but the economy has yet to see a significant boost from the effort.
