The U.S. dollar is on track for its largest weekly decline since January, down 1.6% as investors move away from safe-haven assets following a fragile ceasefire in the Gulf region. The euro has rallied 1.8% this week, trading at $1.17255, while the British pound has gained 2% to $1.346. Analysts suggest that market sentiment is optimistic despite the ceasefire's fragility, as indicated by the significant rises in the risk-sensitive Australian and New Zealand dollars, both nearing 3% increases against the dollar. The upcoming peace talks between the U.S. and Iran in Islamabad are expected to heavily influence market direction. If the talks yield positive results, the dollar could weaken further, while any setbacks could quickly reverse current trends. Notably, the yen has seen slight gains but remains under pressure due to Japan's low interest rates and high oil prices. Meanwhile, China's yuan is set for its largest weekly rise in 15 months, trading at its strongest levels of 2023, despite China's status as the largest oil importer.
