Hormuz tanker traffic drops by 60%

Thirteen oil tankers crossed the Strait of Hormuz on Wednesday, down from an average of 33 the week before (CNBC). Three Qatari LNG carriers and an Indian supertanker carrying two million barrels of Kuwaiti crude reversed course. No government has declared a blockade, but maritime-intelligence firm Windward describes the route as "functionally contested" (CNBC). For Europe, the distinction matters: the gap between formally open and commercially usable is where the cost now sits.

The Chain of Private Decisions

Governments can negotiate ceasefires. The US-Iran deal signed on June 17 lasted nineteen days before attacks on July 6-7 damaged three vessels near the strait (Al Jazeera, AP News). After that, the decisions that shape Europe's energy cost pass to private actors, each adding delay.

Insurers set risk premiums. Shipowners choose whether to sail. Refineries decide how fast to adjust product prices. Retailers pass costs to consumers at whatever pace competition allows. The European Central Bank (the eurozone's monetary authority) reacts only after the shock has entered consumer prices. By the time Frankfurt acts, a tanker captain has already turned around.

What the Route Now Costs

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

A single clean-products cargo from the UAE to northwest Europe was fixed at roughly $10 million, more than double January's price (OPIS).

Crude benchmarks have fallen back, which makes the shock look smaller than it is. European consumers do not buy crude. They buy diesel, jet fuel, heating oil and gas, products whose prices carry shipping, insurance, refining and retail costs that adjust far more slowly. Each country absorbs those costs differently.

In France, TotalEnergies CEO Patrick Pouyanné estimated three to four months before pump prices normalize, because chartering contracts and shipping risk lag behind the crude price (Le Monde). In the Netherlands, the competition authority ACM found that pump prices had not returned to pre-crisis levels because wholesale and refinery costs stayed elevated (ACM). Italy adds a domestic complication: industry body Unem calculated that refining margins, not crude, drove most of diesel's price increase since February, and a fuel excise discount expiring on July 4 added about €0.061 per litre independently of the Gulf crisis (Auto.it, Motor1). What voters pay at the pump depends on local taxes and refining structures as much as on the barrel price.

Frankfurt's Bind

The ECB estimated on July 2 that 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). Governing Council member Fabio Panetta warned the bank cannot commit to a fixed rate path while energy markets remain unsettled (Banca d'Italia). A supply shock that weakens growth argues for easier money. A supply shock that lifts inflation argues against cutting rates. Both pressures hit Frankfurt at once, and the ECB has no tool for reopening a strait.

Europe cannot control Hormuz, compel shipowners to sail, or set the risk premiums that decide whether cargo moves. The market is already pricing European energy as if that control has been lost.
