The market downturn followed reports that Iranian officials described the US ceasefire proposal as unbalanced and based on excessive demands, rejecting it in its current form.
A senior Iranian official, quoted by state media, said any ceasefire would only be considered on Iran’s own terms and ruled out immediate negotiations. The official added that military defensive operations would continue unless Iran’s conditions are met.
