Finally, and perhaps least appreciated, is the fact that central-bank policy pronouncements are almost unique in having clear and predictable effects on financial markets, at least in the very short run (which can be a day or less). If Fed officials surprise markets by making more “hawkish” statements (suggesting an upward bias to policy interest rates) than investors were expecting, the dollar will usually appreciate; long-term dollar interest rates will usually rise; and the stock market typically will decline.
最后，或许也是人们最少认识到的一项。就是中央银行的政策声明会对金融市场产生几乎独一无二的明确且可预测的效应（可能会持续一天或者更少时间）。如果美联储的官员通过发表比投资者原先预计更多的“鹰派”声明（暗示可能调高政策利率）而令市场感到震惊，美元经常会因此升值；长期美元利率往往会上涨，而股票市场则一般会下跌。
