The Toll That Spared Its Friends

When Iran began charging tankers for passage through the Strait of Hormuz in March, it made one exception explicit: Malaysia. The IRGC classified Malaysian vessels as "friendly parties" and exempted them from tolls that reached $2 million per tanker for everyone else ^[1].

Non-hostile vessels, including those belonging to or associated with other States, may — provided that they neither participate in nor support acts of aggression against Iran and fully comply with the declared safety and security regulations — benefit from safe passage through the Strait of Hormuz in coordination with the competent Iranian authorities. — Iran

China and Thailand received the same treatment — the toll was a lever, and friends did not pay ^[2]. This week, under an American naval blockade, Malaysia raised fuel prices anyway. The government hiked unsubsidised RON95 by 5 sen and diesel by 10 sen, explicitly blaming "geopolitical risk premiums" for the increase ^[3].

This development is driven by the reduction in geopolitical risk premiums, the restoration of supply flows and increased price competition among major producers. — Ministry of Finance, Malaysia

The country Iran spared is the country America taxed. The two systems that have governed the Strait of Hormuz since March operate on opposite principles, and the difference is now visible in fuel bills from New Delhi to Jakarta. Iran's "Tehran Toll Booth" was calibrated and selective. The IRGC charged up to $2 million per tanker for safe passage but built the system around a friend/punish logic: vessels linked to the United States and Israel were blocked, while those from Malaysia, China, and Thailand passed freely ^[2][1]. It was a diplomatic instrument that generated revenue rather than disrupted supply — a toll that could be lifted or lowered by agreement. During the June ceasefire, it was. The American naval blockade that replaced it this week is a different kind of instrument. The US did attempt to limit its reach: CENTCOM stated the blockade would "not impede freedom of navigation for vessels transiting the Strait of Hormuz to and from non-Iranian ports," and the Navy ran a parallel operation to protect and guide commercial vessels through the waterway ^[4][5].

But the insurance market did not read the fine print. War-risk premiums surged from 2% to 6% of hull value for all vessels regardless of flag or destination, Lloyd's shifted to six-hour pricing windows, and the International Maritime Organization warned all commercial shipping away from the strait, stranding some 20,000 seafarers ^[6].

The distinction the Navy drew between Iranian and non-Iranian traffic was one the underwriters could not price — so they priced everyone. The mechanism from there is direct. Brent crude rallied roughly 12% in three days to over $83 a barrel ^[7]. And third-party governments, one after another, opened their domestic fuel-pricing toolkits. India raised its diesel export windfall tax from Rs 8.5 to Rs 15.5 per litre and aviation turbine fuel from Rs 7.5 to Rs 14.5 ^[8]. The Reserve Bank of India had warned weeks earlier that any breakdown in US-Iran talks would reignite inflation and disrupt energy infrastructure — a prediction the blockade confirmed ^[9].

During the May blockade, Indian oil companies had already raised petrol and diesel four times in eleven days, with diesel crossing Rs 100 per litre ^[10]. The pattern is now repeating. The reach extends well beyond South Asia. Japanese construction firms absorbed 70% spikes in PVC prices and project delays. Indonesian ferry operators demanded tariff adjustments as the rupiah depreciated and imported spare parts rose 30% ^[11]. US consumers are not exempt: average gasoline hit $3.87 a gallon, with GasBuddy projecting $4 within ten days ^[7]. And yet the blockade is materially leaky. Over a four-week period during the blockade, Iran exported more than 80 million barrels of oil through its dark fleet, worth roughly $6 billion, with another 30 million barrels awaiting departure and 60 million in floating storage.

Given that the structures foreseen for the continuation of oil exports have been maintained, the country's oil export process continues as before and, God willing, we will not face any problems in this regard. — Mohsen Paknejad

The US Navy disabled one tanker — the M/T Belma, struck by Hellfire missiles near Kharg Island — and forced others to U-turn, but the volume moving through the back channels suggests the blockade is kinetically real without being economically effective against its target. The result is an asymmetry that the Iranian toll system, for all its coercive intent, did not produce. Iran's toll was a lever that could be lifted or lowered by agreement — and during the June ceasefire, it was. The American blockade is a switch. It cannot be half-thrown. And because it does not stop the oil it is meant to stop, its primary economic burden falls on governments that have no stake in the US-Iran conflict — but whose domestic fuel-pricing machinery now responds, automatically, to every escalation in the Gulf. New Delhi, Kuala Lumpur, and Jakarta are not parties to this war. But they are, whether they chose it or not, administering its costs through their own budgets.
