**Summary**: WSJ reports that President Trump has instructed aides to prepare for a prolonged blockade of Iranian ports, signaling an extended disruption to Iran’s crude and condensate export capacity. This materially raises the medium‑term geopolitical risk premium in oil and LNG, especially for Asian buyers and shadow-fleet exposed traders.

## Detail

Multiple reports (WSJ citations in [13], [20], [27]) indicate that President Trump has decided to maintain a long‑term blockade on Iran’s ports rather than escalate to direct large‑scale military action or wind down the confrontation. While some sanctions pressure on Iranian oil is longstanding, an extended, actively enforced port blockade is qualitatively different: it seeks to interdict physical export flows, not just financial channels.

Operationally, a serious blockade of Iran’s key export terminals (Kharg Island, Assaluyeh and other Gulf ports) could curtail a large share of Tehran’s 1.5–2.0 mb/d of crude and condensate exports, much of which currently moves through opaque channels to China and other Asian buyers. Even partial interdiction or a chilling effect on the shadow fleet (older tankers with weak insurance, obscure ownership) will tighten prompt availability of medium and heavy sour barrels in Asia and the Med, and complicate supply for refiners calibrated to Iranian grades.

From a market standpoint, this is a textbook supply‑side shock plus risk‑premium event. Historically, sharp escalations around Iranian exports – e.g., the 2011–2012 sanctions tightening and the 2019 tanker attacks in the Gulf of Oman – have added several dollars per barrel to Brent’s risk premium and triggered >1% daily moves. A formal, prolonged blockade threat is more aggressive, as it implies persistent naval enforcement and elevated odds of incidents in or near the Strait of Hormuz, through which roughly 20% of global oil trade and significant Qatari LNG volumes transit.

Immediate impact is higher Brent/WTI, steeper front‑end backwardation, and wider sour‑sweet spreads. Bullish pressure will center on Brent, Dubai, Oman benchmarks and on tanker freight and war‑risk insurance premia for Gulf routes; LNG risk premia in Asia may also edge up on elevated Hormuz transit risk. Duration is likely multi‑month or longer given the framing as a long‑term strategy choice; even before full implementation details are known, positioning and hedging flows can drive swift repricing.

Secondary effects include support for rival Gulf producers (Saudi, UAE, Iraq) and for U.S. shale-linked names, as well as upside in gold and defense equities as geopolitical tension proxies.

**AFFECTED ASSETS:** Brent Crude, WTI Crude, Dubai Crude, Oman Crude, Asian LNG spot, Tanker freight indices (MEG-Asia), War risk insurance premia (Gulf), Gold, USD/IRR, Middle East oil producer sovereign CDS
