LONDON/SINGAPORE—The dollar slid from a 12-week peak on Monday after Federal Reserve Chair Jerome Powell left open the possibility of further rate hikes, while the China-sensitive euro edged up in the wake of Beijing halving its stamp duty on stock trading.
The dollar index, which measures the U.S. currency against six peers, edged 0.06 percent lower at 104.11, after hitting its highest since early June on Friday. The index is up over 2 percent in August and set to snap a two-month losing streak.
