**Summary**: The US confirms full implementation of a naval blockade of the Strait of Hormuz while Iranian forces have attacked five merchant vessels and seized two. A second US carrier will reinforce the blockade, and rules of engagement now authorize destruction of Iranian units laying mines. This sharply raises near-term disruption risk for Gulf crude and product exports and adds a substantial geopolitical risk premium across energy and shipping.

## Detail

1) What happened: In the last hour, multiple senior US defense officials confirmed that Washington is now fully implementing a blockade in the Strait of Hormuz. General Dan Caine stated that Iran has attacked five merchant ships and captured two previously authorized to transit the strait. War Secretary Pete Hegseth added that a second US aircraft carrier will join the blockade within days, calling the blockade “global,” and publicly authorized US forces to “shoot to destroy” Iranian assets laying mines or threatening US shipping. This comes on top of prior US announcements of a Hormuz blockade and a three-carrier presence in the region, but today’s statements confirm full enforcement, new Iranian attacks on neutral shipping, and a hardening of rules of engagement.

2) Supply/demand impact: Around 17–20% of global crude and ~20–25% of seaborne LNG flows normally transit Hormuz. Even if physical flows have not yet collapsed, the combination of an explicit blockade, documented attacks on five merchant vessels, and active interdiction/mining risk materially increases the probability of partial flow disruption. Traders and insurers will price in the possibility of several million barrels per day of exports from Saudi Arabia, UAE, Kuwait, Iraq, and Iran being delayed, rerouted, or temporarily shut-in. LNG flows to Asia from Qatar are particularly exposed. In the near term, spare capacity and some bypass via east–west pipelines can mitigate part of the loss, but not all, especially for condensate and LPG. Demand-side impacts are secondary at this stage; the immediate effect is a risk premium on supply.

3) Affected assets and direction: Brent and WTI crude futures should see a significant upside move, with front-month contracts most sensitive as traders reprice tail risks of a multi-million-bpd disruption. Time spreads (Brent and Dubai) are likely to flip more backwardated. Asian LNG spot benchmarks (JKM), European TTF, and Middle East LPG benchmarks should all reprice higher on transit and insurance risk. Tanker equities (especially VLCC owners) and war-risk insurance premia for Gulf routes should spike. Safe havens such as gold and the US dollar vs EM FX (notably importers like INR, TRY, PKR) are biased stronger; currencies of oil importers may weaken on terms-of-trade deterioration.

4) Historical precedent: Analogous episodes include the 1980s “Tanker War,” the 2019–2020 Gulf tanker attacks, and the 2024–25 Red Sea disruption. In those cases, even without a formal blockade, risk premia added several dollars per barrel to Brent and widened tanker rates sharply. A formally acknowledged, actively enforced blockade of Hormuz is more severe and historically rare, implying a larger and more persistent premium.

5) Duration: The impact is likely to be medium- to long-lived (weeks to months) as diplomatic efforts to de-escalate and/or negotiate carve-outs will take time, and market confidence in safe passage will lag any political announcement. Even if actual volumetric disruptions are intermittent, the mere operationalization of a “global” blockade with kinetic incidents against merchant shipping creates a structural risk premium until there is a clear and durable political resolution.
