Key takeaway

Iran is converting Hormuz from a blockade into a bilateral licensing system it controls.

Iran exempted Iraq from all Strait of Hormuz restrictions on 5 April, citing "brotherly" ties. ¹ Iraq's oil production had collapsed from 4.3 to 1.2 million barrels per day under the blockade, a 72% drop costing roughly $200 million daily. Oil is the single revenue source that funds Iraq's government. The exemption is a survival measure for both sides: Iraq's economy cannot function without Hormuz access, and Iran needs at least one friendly neighbour whose state has not been destroyed by Iranian policy.

Weekly Hormuz transits rose to 53 last week, up from 36, but still down over 90% from the pre-war normal of roughly 966. The increase is driven entirely by bilateral exemptions: the Philippines, France , Japan, Oman, and now Iraq. Each deal further normalises Tehran's sovereignty claim over international waters. The coalition posture Washington maintained since the blockade began is dissolving into a series of licensing arrangements administered by Tehran.

Ali Vaez of the International Crisis Group assessed that Hormuz control is "much more potent than even a nuclear weapon." Former CIA Director Bill Burns said Tehran has "tasted its power and leverage and won't soon give it up." US intelligence simultaneously assessed Iran will not open Hormuz "any time soon." ²

Deep Analysis

In plain English

Iran is blocking most ships from passing through a narrow waterway that most of the world's oil passes through. Iraq, which is Iran's neighbour and has historically friendly relations with Tehran, was losing three-quarters of its oil income because of the blockade. Iran has now said Iraq's ships can pass through. This sounds like a concession, but it is actually something more significant: Iran is deciding country by country who gets to use an international waterway, and charging them for the privilege. That is a fundamental change in who controls global oil shipping.

Primary parallel: The Allied blockade of Germany in World War I — initially comprehensive, progressively eroded by neutral exemptions for Scandinavian states, ultimately maintained as an instrument of pressure through selective enforcement. The Hormuz bilateral exemption system follows the same structural trajectory: a nominally total blockade converting into a managed licensing regime administered by the blocking power.

Counter-parallel: US oil sanctions on Iran from 2018 — also built around bilateral exemptions for India, China, South Korea, and others. Those exemptions steadily eroded the sanctions architecture until they were eliminated. Iran appears to have learned from watching its own sanctions erosion and is now applying the exemption model offensively.

Iraq's 72% oil production collapse from 4.3 to 1.2 million barrels per day costs Baghdad approximately $200 million daily. Oil is Iraq's sole material revenue source, funding 90% of government expenditure. Without Hormuz access, Iraq faces a fiscal crisis within weeks.

The exemption does not restore Iraq's full production: ships must still transit the Larak Island IRGC corridor, paying in Iranian rial. Each Iraqi barrel that transits contributes to the 53 weekly transits counted last week, still down 90% from pre-war baseline. The economic relief is partial; the political signal to Arab states watching the bilateral exemption system is total.

Consensus view: International Crisis Group's Ali Vaez and former CIA Director Bill Burns both assess that Iran will not relinquish Hormuz control voluntarily, having assessed the strait as more strategically valuable than its nuclear programme. Each bilateral exemption reinforces this assessment by demonstrating that Tehran can manage the blockade selectively without global coalition forming against it.

Counter-view: Carnegie Endowment's Karim Sadjadpour argues the Iraq exemption exposes a structural flaw in Iran's Hormuz strategy: a blockade that Iran must selectively abandon to prevent the economic collapse of its closest ally is not a sustainable strategic instrument.

Key tension: Whether Iran's bilateral exemption system is a sign of Hormuz leverage being strategically managed or of the blockade becoming unworkable under its own weight.

Different Perspectives

Israel

The IDF struck a Lebanese army unit on 6 June, killing a colonel, and privately told Moscow that shelling near Bushehr was accidental, per Putin's SPIEF disclosure. Israel is advancing in Lebanon past an unenforced ceasefire text while maintaining a back-channel to Russia on nuclear-site deconfliction.

Lebanon

President Aoun told CNN on 5 June that Iran uses Lebanon as a bargaining chip and urged Hezbollah toward diplomacy; on 6 June an IDF strike killed a Lebanese army colonel on the Khardali-Nabatieh road. The Lebanese state is publicly rejecting Iranian tutelage while the army sustains casualties from Israeli fire and the Washington framework remains unenforced.

Bahrain

Bahrain's US Fifth Fleet headquarters was among the targets in the 5-6 June two-country salvo; its PAC-3 magazine stands at 87 per cent depletion with an 18-month resupply gap and no comparable arms sale has been announced. The state is defending a critical US regional command on a thinning interceptor stock.

Kuwait

Kuwait received a $1.98bn US counter-drone sale approval on the same day IRGC missiles targeted its bases; it expelled two Iranian diplomats on 4 June and filed a formal protest. The arms approval gives Kuwait a future capability but leaves a 6-18 month delivery gap that the salvo tempo is already pressing.

Russia

Putin reaffirmed Russia's offer to hold Iran's 440.9 kg HEU at SPIEF on 6 June, said Russia is not arming Iran, and disclosed that both the US and Israel privately told Moscow that shelling near Bushehr was accidental. The restatement casts Moscow as the only remaining mediator both sides call, a position serving Russian interests whatever the nuclear file produces.

Iran

The IRGC, per Iranian state media, fired seven ballistic missiles at US bases in Kuwait and Bahrain, the largest two-country salvo of the war, and framed the launches as lawful retaliation; Foreign Minister Araghchi rejected Aoun's bargaining-chip accusation and Velayati warned Beirut against diplomatic naivety. Tehran has sent no HEU counter-proposal since Araghchi confirmed no progress on 4 June.
