The Fed is keeping its rates near zero. It will also continue with its program of quantitative easing to stimulate the economy as long as the jobless rate stays above 6.5 per cent.
There has been a growing expectation that it may be tempted to reverse its position after minutes from the last meeting in December showed a split among members over how long to continue the stimulus. Some thought the program should be slowed or stopped before the end of 2013.
