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.
