A U.S. flag flies on top of the Marriner S. Eccles Federal Reserve building at sunrise in Washington, D.C., U.S., on Tuesday, Oct. 28, 2014. The Federal Open Market Committee meets today and tomorrow after six weeks of volatility in global financial markets. Since the FOMC met in mid-September, oil prices have tumbled 14 percent, and the Standard & Poor's 500 Index of stocks dropped as much as 7.4 percent from a record close.
