Carvina Capital Notes Iran Tanker Tactics Shift

Iran's wider tanker campaign beyond the Strait of Hormuz and a Houthi missile strike on Saudi Aramco's headquarters keep Brent above $100 and test Saudi export routes before next month's US midterm elections

Global energy markets take a double blow from the Gulf this week, as a Houthi missile strike on Saudi Aramco's headquarters compounds Iran's wider campaign against shipping. With incidents near Hormuz at their highest frequency since the conflict began, Brent crude holds above $100 a barrel across recent sessions and Goldman Sachs warns of $120 should the attacks escalate. Tehran ties the pressure to next month's US midterm elections, and Carvina Capital is analysing what this convergence means for asset resilience and long-term planning.

Iran's revised approach, adopted less than a fortnight ago, changes the type and pace of attacks on vessels it regards as breaching its restrictions. Operations now reach beyond the Strait of Hormuz into the Gulf of Oman and waters off Qatar and the UAE, and reports count twelve vessels struck in the week to last Sunday, with six attacks on that Sunday alone. Iranian officials say the top leadership approved the strategy to frustrate Washington's push for lower oil prices before the vote, one likening the standoff to a game of chess.

American accounts are more measured, and a US official says Iran relies on unarmed spotters in small boats after strikes destroyed its radar. Tehran's reluctance to risk its fast boats, the official adds, has left it unable to prevent higher exports through the strait. Kpler data shows Gulf oil flows reaching a wartime high of 15.5 million barrels per day last month, yet volumes fell sharply to 2.9 million barrels last Sunday. Hormuz traffic averages about 29 transits a day through the current disruption, against a historical baseline of roughly 138.

Yemen's Houthi movement now carries the threat onto Saudi soil, after a ballistic missile struck Aramco's Dhahran headquarters on Tuesday night. A company source says the strike damaged the top three floors of an office tower and started a fire, while the energy ministry reports limited damage and no casualties. The Abqaiq attack seven years ago removed 5.7 million barrels per day of Saudi output, yet Aramco restored production within two weeks and prices later fell below pre-attack levels.

Prices still climb after the Aramco strike and Iran's change of tactics, sending West Texas Intermediate to a three-week high. Brent gains 0.8% to $101.6 a barrel in a later session this week, with WTI also up 0.8% at $90.5. President Donald Trump accuses the Houthis of deliberately trying to drive up prices before the midterms and says Washington could join Saudi Arabia's campaign against the group.

What sets this episode apart from Abqaiq is that the oil price now sits at the centre of a political contest between Tehran and Washington. Markets can price a one-off outage with some confidence, but a campaign that follows an election timetable is far harder to value. The Abqaiq precedent, in the reading of the Senior Vice President at Carvina Capital Pte. Ltd., Stephen Cross, is grounds for caution, since "a single strike whose lost output returned within a fortnight is a very different proposition from sustained pressure on shipping lanes, pipelines and export terminals at once".

Saudi Arabia's ability to divert crude from Hormuz rests largely on the East-West Pipeline, or Petroline, and the export terminal at Yanbu. Energy Information Administration data shows Hormuz flows of crude and petroleum liquids falling from 21.6 million barrels per day in the final quarter of last year to 4.9 million by the second quarter, a 77% decline. The kingdom's energy minister puts pipeline flows back at 5.8 million barrels per day by early this month, against capacity of 7 million, after drone strikes forced a temporary shutdown. Yanbu repeatedly nears its own limit of about 5 million barrels per day.

Houthi threats against the Bab el-Mandeb Strait, which currently carries about 7.4 million barrels a day, or 7% of global output, leave the Yanbu route exposed too. Asia now takes more than 80% of Yanbu's cargoes, and a closure would force those shipments through Suez and around Africa, stretching voyages from roughly 20 days to 50. Security analysts warn that pressure on both chokepoints at once would deliver a far larger jolt than disruption at either alone. The widening Brent-WTI gap in recent trading shows that oil shipped through these waters already costs more.

Russian diesel offers limited relief, since pledged volumes are set to rise from 75,000 barrels a day this month to 250,000 towards the end of the year. With so thin a cushion, Cross regards liquidity as the decisive buffer, describing it as "the discipline that allows a business to absorb an energy shock rather than be forced to react to it". Carvina Capital continues to track Hormuz traffic, Gulf export data and the Brent-WTI spread as the clearest signals of whether today's premium hardens before the midterm vote.
