The dollar extended its losses on Monday, retreating from its highest levels since 2003 as U.S. Treasury yields eased from recent peaks, Reuters reported. After hitting an almost 14-year-high of 102.05 on Thursday, the dollar dipped on Friday and added to those losses on Monday, with the index down 0.7 percent at 100.82 by 0820 GMT, tracking 10-year U.S. Treasury yields lower. The greenback fell 1.2 percent to 111.865 yen. The euro climbed as much as 1.1 percent against the greenback to an 11-day high of $1.0686, benefiting from the dollar's broad weakness.
