The U.S. Dollar decreased on Thursday falling from the highest level in three weeks against the Japanese Yen after the pair reached the so-called technical resistance and as political uncertainty persisted after the short-term debt deal passed by U.S. Congress. The Greenback fell 0.3% to 98.50 yen by 6:39 a.m. London time following an increase to 99.01, the highest since September 27.
