Dollar reigns with the support of higher yields

The Japanese yen traded around five-month lows on Monday against a dollar underpinned by rising U.S. yields as thin year-end liquidity kept most currencies in tight ranges. The yen was changing hands at 157.71 with only the risk of Japanese intervention preventing another test of the 160 level last seen in July. The dollar index measure against major rivals was flat at 107.98.
