**Summary**: New reporting that Iran has laid 20 naval mines in the Strait of Hormuz, with clearance expected to take up to six months, hardens the reality of a protracted disruption risk to Gulf exports. This escalates the supply-side threat already partially priced, supporting a higher and more persistent risk premium in crude and LNG benchmarks and related freight.

## Detail

1) What happened:
Washington Post-linked reporting states Iran has placed 20 naval mines in the Strait of Hormuz designed to channel shipping into an Iranian-controlled corridor, with mine clearance estimated to take around six months. This is a concrete, operational confirmation of earlier, more general statements about mining the strait and significantly reduces the probability that the blockade risk is short-lived or easily reversible.

2) Supply impact:
Roughly 17–18 mb/d of crude and condensate and ~20–25% of global LNG trade normally transit Hormuz. Even if shipping continues via an Iranian-designated corridor under escort, insurers and charterers will price in elevated war-risk premiums, and some buyers (particularly Western majors and certain Asian refiners) may avoid the route or specific flagged cargoes. The mines themselves materially raise the probability of a high-impact incident (tanker damage/sinking or naval clash) that could temporarily halt traffic entirely. Near term, the physical flow reduction could range from modest (1–3 mb/d equivalent) in a managed-risk scenario, to extreme (10+ mb/d) in a worst-case closure. The key new element is duration: a six-month clearance horizon means even if tensions ease, the technical hazard persists, maintaining a structural premium.

3) Affected assets and direction:
Brent and WTI should see sustained upside pressure with a fatter right-tail risk; near-dated time spreads likely to strengthen (backwardation) as prompt barrels gain scarcity value. Dubai/Oman benchmarks and Middle East differentials will be especially sensitive, as will LNG spot prices in Europe (TTF) and Asia (JKM) given re-routing risks and potential outages of Qatari flows. Freight (VLCC, LNG carrier rates) and war-risk insurance premia should rise. Safe-haven assets (gold, JPY) may catch risk-off flows if markets extrapolate toward a direct US–Iran confrontation.

4) Historical precedent:
Iran–Iraq "Tanker War" (1980s) and 2019 mine/sabotage events in the Gulf both generated multi-dollar Brent moves on far less explicit and sustained mining activity. A formalized six-month hazard window is rarer and more akin to a quasi-embargo risk than a one-off incident.

5) Duration:
This is a structural, not transient, shock. Even with no further escalation, clearing confirmed mines and restoring confidence in the route will take months, embedding a durable risk premium into energy markets.
