Hormuz Tanker Traffic Falls 60%

On Wednesday, just 13 oil tankers crossed the Strait of Hormuz. A week earlier, the average was 33 (CNBC). Three Qatari LNG carriers turned back, as did an Indian supertanker carrying two million barrels of Kuwaiti crude. No capital has declared a blockade. But Windward, the maritime-intelligence firm, now describes the route as "functionally contested" (CNBC).

For Europe, that is the difference that matters. A sea lane can remain formally open while becoming too risky, too expensive or too unpredictable for normal commerce. The cost sits in that gap.

The Chain of Private Decisions

Governments can sign ceasefires. They can send messages through intermediaries. They can insist, in public, that shipping routes remain open. The US-Iran deal signed on June 17 lasted 19 days before attacks on July 6-7 damaged three vessels near the strait (Al Jazeera, AP News).

After that, the practical decisions moved out of the hands of foreign ministries and into the hands of private actors. Insurers set war-risk premiums. Shipowners decide whether a voyage is worth it. Refineries judge how quickly to adjust product prices. Retailers pass on costs at the pace local competition allows.

Only later does the European Central Bank, the eurozone's monetary authority, see the shock in consumer prices. By the time Frankfurt has something to respond to, a tanker has already changed course.

What the Route Now Costs

War-risk premiums have reached about 2.5% of a vessel's insured value for a seven-day transit, while Asia-Europe freight rates are running roughly 20% above pre-crisis levels (Eurogroup Consulting). Danish shipping groups Maersk and Norden have judged conditions too uncertain to sail through (Børsen).

One clean-products cargo from the UAE to northwest Europe was fixed at roughly $10 million, more than twice its January price (OPIS).

Crude benchmarks have eased back, which makes the shock look neater than it is. European households and businesses do not buy crude oil. They buy diesel, jet fuel, heating oil and gas. Those prices carry the costs of shipping, insurance, refining and retail margins, and they move more slowly than the headline barrel price.

Each country then feels the shock through its own tax system, refinery structure and retail market. In France, TotalEnergies chief executive Patrick Pouyanné estimated it would take three to four months for pump prices to normalise, because chartering contracts and shipping risk lag behind crude prices (Le Monde). In the Netherlands, competition authority ACM found that pump prices had not returned to pre-crisis levels because wholesale and refinery costs remained elevated (ACM).

Italy has its own complication. Industry body Unem calculated that refining margins, rather than crude, drove most of diesel's price increase since February. A fuel excise discount expiring on July 4 added about €0.061 per litre separately from the Gulf crisis (Auto.it, Motor1). What voters pay at the pump is shaped as much by local taxes and refining capacity as by the global oil price.

Frankfurt's Bind

The ECB estimated on July 2 that a persistent Gulf disruption could raise euro-area inflation by 1.3 percentage points at its 2027 peak and put up to 3% of production at risk (ECB). Fabio Panetta, a member of the ECB Governing Council, warned that the bank cannot commit to a fixed path for interest rates while energy markets remain unsettled (Banca d'Italia).

That is Frankfurt's problem. A supply shock that weakens growth points towards easier money. A supply shock that lifts inflation points away from rate cuts. Both arguments arrive together, and the ECB has no instrument for reopening a strait.

Europe cannot control Hormuz. It cannot force shipowners to sail. It cannot set the insurance premiums that decide whether cargo moves. The market is already pricing European energy as though that control has slipped out of reach.
