Hormuz: Epicenter of a Worsening Insecurity

Eight months into the conflict between the United States and Iran, October marks the sharpest escalation at sea: more than 30 incidents have been recorded in the strait and its approaches, versus 14 in September. The threat no longer targets only vessels attempting to pass discreetly: a tanker was struck in Iraq's exclusive economic zone. VLCCs, the largest tankers in existence, account for 28% of drone and missile attacks in the Persian Gulf. The 32 vessels hit represent nearly 4% of the global fleet in this category.

This insecurity carries a measurable price. A Saudi Arabia-China rotation costs about ? per barrel of freight, and regional demurrage, rising since mid-August, reaches ?,000,000 per day. Brent holds near ?. Maritime security operators also acknowledge that documenting strikes is becoming harder, as vessels prefer to sail undetected and charterers fear further rate increases.

A Second Front: The Red Sea and the Arabian Peninsula

The Gulf is not the only flashpoint. The Houthis claim to have struck the Ras Tanura refinery, Saudi Arabia's largest at 550,000 barrels per day, with a ballistic missile, triggering a fire. A March attack had already shut it down for three months. The Saudi-Houthi confrontation appears to be gaining its own momentum, independent of negotiations with Tehran. The current Brent ceiling largely depends on Qatari and Pakistani mediation, and markets anticipate a possible escalation after the US midterm elections on November 3.

Faced with this uncertainty, OPEC+ holds steady. The seven core members are expected to maintain December targets and focus on 2027 quotas, having completed the withdrawal of 1.65 million barrels per day in voluntary cuts, a timetable disrupted by the Hormuz crisis.

Asia Secures Its Supplies

Importers are responding by abandoning market logic. Indonesia plans to replace tenders for its crude and refined product imports with state-to-state or state-to-company agreements, and is courting India and China for long-term contracts. Singapore launches its first long-term LNG tender, while neighboring Indonesia cuts pipeline gas exports by 15% to 31 MMcf/d. Malaysia proposes extending the life of its coal plants despite its 2044 phase-out commitment: coal accounts for 56% of its power generation, while JKM has surged to ? per MMBtu. In each case, constrained Gulf access pushes toward diversifying sources and prioritizing supply security over cost.

The refined products trade is also realigning. An announced agreement between Donald Trump and Vladimir Putin provides for Russian diesel deliveries to the United States, totaling about 300,000 tonnes according to OSINT elements. Commentators judge the volume too small to lower pump prices and highlight the tension with sanctions policy. US diesel reaches ?.30 per gallon.

Europe Pays in Confidence

The consequences show up in household budgets. In France, the Insee household confidence indicator lost five points in October and returns to its lowest level since 2013. The opinion balance on future financial situation drops nine points, that on recent situation six. Economist Eric Heyer of OFCE sees uncertainty weighing on purchasing power and forecasts higher savings and lower consumption. Among the remedies, he cites reopening the Strait of Hormuz and adopting a 2027 budget.

The effects are measurable at the individual level. In a nursing home in Pas-de-Calais, a care assistant spends 250 euros more per month on fuel, a colleague estimates her bill up nearly 50%, and the facility pays a 500-euro bonus, about 50,000 euros in total. The state, for its part, opens a 100-euro fuel voucher, which 5.5 million people can claim. Fiscal policy thus becomes a direct shock absorber for the maritime shock.

Arsenals and Alliances Under Strain

The war also draws on military stockpiles. Patriot interceptors, widely used in the Middle East, have seen their reserves heavily depleted according to analysts, while Ukraine desperately lacks them to intercept Russian ballistic missiles. In this context, Poland has secured a maintenance center for these missiles, at a cost of one billion zlotys (230 million euros). Warsaw hopes to produce them next. The USS Abraham Lincoln returned to San Diego after 322 days of deployment, including 265 consecutive at sea. The episode crystallized criticism of the length of a war that 65% of Americans disapprove of, against 33% who approve, according to a poll.

Trade Routes Between Protection and Retaliation

The shock compounds a broader trade fragmentation. The United States is considering extending until January 9 the truce on port fees targeting China-linked vessels. The European Union is studying quotas or tariffs on Chinese chemicals, furniture and machinery from early 2027, to reduce a 360-billion-euro trade deficit.

What the Data Shows, and What It Doesn't

The picture remains partial. The file contains no volumes transiting Hormuz, no pre-war prices, no bilateral trade statistics, and the Ras Tanura strike is a Houthi claim. The link between household confidence and fuel prices rests on expert analysis, not measurement. The current Brent ceiling depends on mediations whose outcome is uncertain.

One can nonetheless retain a coherent causal chain: maritime insecurity, higher freight and crude costs, importer securing strategies, eroding confidence and fiscal margins in Europe. The early-November calendar will be the first test.
