Summary
Iran’s deputy foreign minister announced Tehran’s withdrawal from a key memorandum of understanding, vowing to exercise “full sovereignty” over the entire Strait of Hormuz, including Oman’s side. This escalatory legal and political stance increases the probability of interference with third-country shipping and amplifies tail risks for Gulf crude and LNG exports.
Details
Iran has publicly announced it is withdrawing from a Memorandum of Understanding with the United States, citing repeated US violations, and declared it will exercise “full sovereignty over the Strait of Hormuz, no matter the costs,” explicitly including Oman’s half of the strait. This statement comes on top of active US naval blockade operations and Iranian missile and drone attacks across the Gulf, signaling Tehran’s willingness to challenge not just US-linked traffic but potentially all transit through the chokepoint.
Substantively, Iran has limited legal grounds to assert control over Omani territorial waters, but the market impact comes from what Iran is politically signaling: that it may attempt interdictions, boardings, or harassment of non-Iranian, non-US-affiliated tankers under the guise of enforcing its “sovereignty.” If operationalized, this could materially increase the number of vessels unwilling to call at or transit near Iranian-controlled lanes, and prompt insurers to further hike war-risk premia or withdraw cover.
On the supply side, any credible threat to non-Iranian flows through Hormuz touches up to ~17–20 mb/d of crude and condensate and large volumes of LNG. Even if actual disruptions remain small – e.g., sporadic seizures or temporary delays affecting a few hundred thousand bpd – the option value of uninterrupted transit is impaired. That is enough to push a further risk premium onto Brent, Dubai, and regional crude benchmarks, as well as to steepen backwardation.
Assets most affected are front-end oil benchmarks (Brent, WTI, Dubai), Middle Eastern grades (Basrah Medium, Arab Light, Murban), and tanker equities/freight indexes. LNG-linked benchmarks (JKM and, indirectly, TTF) also gain upside optionality given Qatar’s export dependence on Hormuz. Historically, even rhetorical closure threats in 2011–2012 moved crude several dollars per barrel without shots fired. Against the backdrop of an active blockade and missile exchanges, this declaration is not just rhetoric; it structurally elevates the probability of a larger disruption and should support a sustained risk premium so long as US–Iran confrontation continues.
AFFECTED ASSETS: Brent Crude, WTI Crude, Dubai Crude, Murban crude, Basrah Medium, Arab Light, VLCC freight rates, JKM LNG, TTF natural gas, Gold, USD/JPY, Oil-sensitive EM FX (e.g., INR, TRY)
