In the United States, the authority to set interest rates is divided between the Board of Governors of the Federal Reserve (Board) and the Federal Open Market Committee (FOMC). The Board decides on changes in discount rates after recommendations submitted by one or more of the regional Federal Reserve Banks. The FOMC decides on open market operations, including the desired levels of central bank money or the desired federal funds market rate.
A higher than expected figure should be seen as positive (bullish) for the USD while a lower than expected figure should be seen as negative (bearish) for the USD.
