**Summary**: US F/A‑18s are now flying from USS Abraham Lincoln in direct support of both the blockade of Iranian ports and ‘Project Freedom’ convoys evacuating tankers through the Strait of Hormuz, while US helicopters have sunk six Iranian boats amid ongoing attacks on commercial traffic. This confirms a shift from localized disruption to a sustained, militarized control regime over Gulf oil flows, reinforcing a higher geopolitical risk premium and tightening physical supply.

## Detail

1) What happened: New reporting confirms that F/A‑18 Super Hornets from the USS Abraham Lincoln are actively supporting two parallel operations: (i) a blockade of Iranian ports, and (ii) ‘Project Freedom,’ under which US forces are escorting and defending commercial vessels transiting the Strait of Hormuz. In the same operational context, US AH‑64 and MH‑60 helicopters have sunk six Iranian boats that were attacking commercial vessels and US warships. This is no longer just a threat environment; it is an explicit, declared maritime protection and blockade regime around the primary chokepoint for seaborne oil.

2) Supply/demand impact: Around 17–18 mb/d of crude and condensate, plus significant refined products and LNG volumes, normally transit Hormuz. Even with some tankers now being escorted out, overall throughput remains sharply constrained by (a) prior closure, (b) reluctance of owners/insurers to route ships through an active warzone, and (c) Iran’s ports being under blockade, effectively curtailing Iranian crude and condensate exports (2+ mb/d pre‑war). Chevron’s CEO has already flagged emerging physical shortages, validating that this is not just a futures-market scare. On current trajectory, export losses in the low single‑digit mb/d range are plausible in the near term, which is sufficient to move flat price several dollars and steepen backwardation.

3) Affected assets and direction: Brent and WTI crude futures should trade higher with an elevated and sticky risk premium; nearby spreads likely tighten sharply. Dubai and Oman benchmarks, plus Middle Eastern OSPs, will reflect regional scarcity. European and Asian gas and LNG prices will gain a secondary bid on fears of knock‑on disruptions to associated gas and LNG flows. Tanker equities and war‑risk insurance premia remain bid; refining margins, especially for middle distillates, likely widen on crude dislocation and product re‑routing. Safe‑haven flows support gold and the USD vs EM FX. Iranian‑linked assets (if traded) will price in deeper isolation; Gulf sovereign credit spreads could widen modestly.

4) Historical precedent: The closest analogues are the 1980s Tanker War, the 2019–2020 Gulf tanker attacks, and the 1990–91 Gulf War. Each episode produced multi‑percentage moves in crude and a durable volatility and risk premium regime, even when volumetric losses were limited.

5) Duration: As long as Iranian ports remain blockaded and combat air/naval operations are active around Hormuz, the shock is structural rather than transient. Even if some flows resume under escort, capacity utilization will be well below normal, and risk premia are likely to persist for weeks to months, not days.
