**Summary**: Donald Trump announced the “most crushing economic operation ever” against Iran, targeting any country, bank, business, airport or government entity providing support. If implemented as described, this implies a de facto secondary-sanctions regime on global trade with Iran, materially raising the risk of disruption to Iranian oil exports and Hormuz traffic, and expanding enforcement risks for third-country entities.

## Detail

Trump’s declaration of an unprecedented economic warfare and isolation campaign against Iran signals a major escalation in U.S. sanctions posture. The language indicates not just tightening of existing Iran sanctions, but an intent to aggressively target any foreign counterparties—states, banks, firms, and infrastructure—that facilitate Iranian trade. That is effectively a threat of broad secondary sanctions and potentially expanded maritime and financial interdiction.

On the supply side, Iran is currently a significant marginal crude supplier, with exports in recent years widely estimated in the ~1.5–2.0 mb/d range, much of it to Asia via complex sanction-evasion schemes. A credible move to criminalize and aggressively prosecute these flows—backed by Trump’s existing naval posture in and around the Strait of Hormuz—could realistically threaten 0.5–1.0 mb/d of effective seaborne supply at risk, even if not all volumes are halted. Traders will price in higher odds of interrupted shipments, tighter insurance and financing, and greater legal/compliance risk for buyers and shippers.

The immediate market reaction is likely a higher geopolitical risk premium in crude and products, steepening the backwardation in Brent and Dubai benchmarks and supporting spreads in high-sulfur grades linked to Iranian alternatives. Brent could plausibly move several dollars higher if the market concludes that enforcement will be rigorous, with front-end contracts and Middle East sour benchmarks (Dubai/Oman) most sensitive. Tanker equities and war-risk insurance premia should also rise.

There is also a broader financial channel: tightened Iran sanctions historically drive safe-haven demand (gold, USD vs EM FX) and weigh on currencies and spreads of key Iranian-linked trade partners or sanction-exposed banks. Previous episodes—e.g., the 2012–2013 EU oil embargo and U.S. secondary sanctions—saw sustained $5–10/bbl risk premia during periods of maximal enforcement.

Duration of impact will hinge on follow-through (formal executive orders, OFAC designations, shipping interdictions). If this campaign is executed as described, the shock is structural over at least 6–12 months, not a transient headline, and keeps markets acutely sensitive to any incident in the Strait of Hormuz or attacks on Gulf energy infrastructure.
