The dollar fell to its lowest level since the Middle East conflict began, surrendering all gains accumulated since the war's start. A report indicating the US and Iran are nearing an agreement to end the nuclear standoff triggered the sharp decline, as markets priced in reduced geopolitical risk in the region.

Currency traders moved quickly to unwind dollar positions built during months of Middle East tensions. The greenback had served as a refuge asset as the conflict escalated, with investors flooding into US assets amid uncertainty. A potential diplomatic breakthrough would fundamentally alter that dynamic, diminishing the dollar's safe-haven appeal that has underpinned its strength.

The dollar's reversal reflects how quickly sentiment can shift when diplomatic solutions emerge. Iran's nuclear program has been a flashpoint for years, and any deal would represent a major shift in Middle East dynamics. For now, traders are watching closely for confirmation of the talks' progress.
