What Happened

How This Reaches Markets

Targeting Chinese purchases of Iranian oil would reduce Iran's primary buyer and foreign exchange source. Secondary sanctions on exchange houses and intermediaries increase transaction costs for remaining trade. Tighter restrictions reduce Iranian oil export volumes, supporting global crude prices.
