US airstrikes continue in southern Iran amid active oil blockade

Summary
Reports indicate ongoing US airstrikes in southern Iran while CENTCOM actively enforces a naval blockade, disabling at least one tanker heading toward Kharg Island. This materially elevates the risk of disruptions to Iranian oil exports and raises the Gulf risk premium across crude benchmarks.
Details
-
What happened: New reporting confirms that US airstrikes in southern Iran are ongoing, adding to earlier confirmed strikes on IRGC-linked targets and port-adjacent infrastructure, and that CENTCOM has disabled a Curacao-flagged tanker (M/T Belma) transiting toward Iran’s Kharg Island after it attempted to violate the declared US blockade. The tanker was disabled with Hellfire missiles into its smokestack in international waters, effectively halting its voyage.
-
Supply-side impact: Kharg Island is Iran’s main crude export terminal, handling the majority of Iranian seaborne exports. A credible, actively enforced US blockade—now demonstrated by kinetic action against a third-party-flagged commercial tanker—poses a serious risk that Iranian exports (currently in the 1.5–2.0 mb/d range depending on estimates) could be sharply curtailed if shipowners and insurers step back. Even before a de facto shut-in, self-sanctioning behavior by owners, insurers, and traders can temporarily remove several hundred thousand barrels per day of Iranian crude and condensate flows as counterparties reassess risk. Continued airstrikes on southern Iran raise the probability of spillover to oil, gas, and export infrastructure directly or via Iranian retaliation in Strait of Hormuz and nearby lanes.
-
Affected assets and direction: The immediate effect is to increase the geopolitical risk premium in the crude complex. Brent and WTI futures are biased higher, with intraday moves of >1–3% plausible on any confirmation of export or loading delays at Kharg or related terminals, and front spreads likely to tighten (backwardation steepening) on perceived near-term supply risk. Dubai/Oman benchmarks and sour crude differentials in Asia should also firm. Tanker equities, especially owners with Gulf exposure, may see higher volatility as war-risk premiums and insurance costs adjust. Gold and defensive FX (JPY, CHF) could get a modest safe-haven bid, while EM FX exposed to oil-import bills may weaken at the margin.
-
Historical precedent: Market behavior during prior Strait of Hormuz scares (2019 tanker attacks, 2020 Soleimani strike) suggests that even without physical flow disruption, demonstrated willingness to use force against tankers can move Brent several dollars on risk repricing alone.
-
Duration: If airstrikes and blockade enforcement persist for days to weeks, the elevated risk premium could become semi-structural, especially if evidence emerges of sustained export reductions. A quick de-escalation would make the impact more transient but today’s actions alone justify a short- to medium-term upward repricing of crude risk.
