US Treasury Secretary Declares 'Economic D-Day' Against Iran Starting Monday

What Happens Next

• →Global crude oil prices rise 5-15% in the near term as markets price in disruption to Iran's ~1.5 million barrels/day of exports, particularly those routed through intermediary channels to China.
• →Chinese refiners currently purchasing discounted Iranian crude face pressure to find alternative suppliers or risk secondary sanctions, tightening the global heavy-sour crude market.
• →Countries maintaining banking relationships with Iranian institutions — particularly in the UAE, Turkey, and Iraq — face US secondary sanctions, forcing compliance or driving transactions further into opaque channels.
• →Iran accelerates reliance on barter arrangements, cryptocurrency, and yuan-denominated trade with China and Russia, deepening its integration into non-dollar financial networks.

Near-term: In 1-3 months, global crude benchmarks rise as traders price in reduced Iranian export volumes; Chinese refiners begin diversifying away from Iranian barrels to avoid secondary sanctions exposure. Long-term: Over 2-5 years, Iran embeds further into a yuan- and ruble-denominated parallel financial system, accelerating the bifurcation of global trade into dollar-aligned and non-dollar blocs.
