Federal Reserve Chair Janet Yellen, in prepared remarks ahead of a congressional hearing Thursday on the state of the U.S. economy, said central bank policy makers would only have to raise interest rates gradually in coming months if they decide to.
U.S. economic analysts are widely predicting a rate increase could be approved at the policy makers' last meeting of the year in mid-December.

Since then, the world's largest economy has added 15 million jobs and the unemployment rate has been cut from 10 percent during the worst days of the plunging economy to 4.9 percent, a normal rate by U.S. standards.
