Iran has publicly rejected US President Donald Trump's assertion that it will sign a new agreement with Washington on Sunday, according to Nettavisen.
The denial directly contradicts Trump's Saturday post on Truth Social, in which he claimed the deal would include the immediate opening of the Strait of Hormuz to all international shipping.
The rejection introduces fresh uncertainty into ongoing diplomatic efforts and near-term shipping risk assessments.
With the Hormuz chokepoint a critical artery for global energy flows, any ambiguity over its status keeps risk premiums elevated.
Markets will now await official statements from Tehran or Washington to clarify whether negotiations are actually progressing or if the timeline has stalled.
