Ongoing US-Iran nuclear negotiations and the status of sanctions relief remain the dominant drivers of USD/IRR positioning ahead of the June 30 resolution. The rial has traded near 1.69-1.7 million per dollar on open-market rates in mid-June, reflecting persistent inflation, restricted oil exports, and limited access to foreign reserves. Recent diplomatic rounds produced incremental progress on enrichment limits and asset releases but yielded no final agreement, leaving traders focused on whether sanctions easing materializes before month-end. A verified deal could support rial stabilization or modest appreciation, while continued enforcement or stalled talks would sustain depreciation pressure. With only days remaining, any official statements on talks or enforcement actions could shift the rate sharply within the resolution window.
