The dollar index rose 0.22% as higher Treasury yields and a more than 2% jump in WTI crude oil prices boosted the greenback. President Trump signaled he would let economic pressure on Iran build rather than launch additional military strikes, while a UAE tanker was targeted by an Iranian missile and Houthi militants claimed an attack on Saudi Arabia's Jazan refinery, keeping safe-haven demand elevated. The euro slipped 0.09% despite the Eurozone Sentix investor confidence index rising to a six-month high of 0.9, as rising energy costs weighed on the region. The yen tumbled 0.73% to a one-week low, pressured by higher crude prices and a 2% rally in the Nikkei, though a hawkish summary of the BOJ's July meeting and reports of coordinated US-Japan intervention provided some support. Gold fell 0.30% while silver gained 1.07%, with the stronger dollar and higher bond yields offsetting support from China's PBOC adding 640,000 ounces to its reserves last month, the largest increase in more than two and a half years.
