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

Qatar

Qatar holds approximately $12 billion in frozen Iranian assets that Tehran named as the precondition for any Hormuz reopening sequence; with Oman sidelined and no agreed HEU custodian, the asset-routing architecture that any deal requires has no operational channel and no neutral financial intermediary to run it through.

Hengaw and Iranian civilian population

Iranians face an internet capped at 40 per cent by hardware their president cannot dismantle, field killings that leave no court record, and judicial executions running in parallel; Hengaw, based in Norway, is the primary remaining monitor of a repression system the IRGC is deliberately moving beyond auditable records. The real toll is higher than any single monitor's count.

China

China supplied deep-packet-inspection hardware that caps Iran's internet at 40 per cent and enables an instant on-demand blackout, and was barred by Trump as a potential HEU custodian on 27 May. Beijing gains from Iran's continued non-alignment with the West while the DPI sale extends Chinese surveillance-technology exports as a geopolitical instrument.

Pakistan

Foreign Minister Ishaq Dar met Rubio in Washington on 29 May, formally inheriting the role of sole active mediator after Oman's forced withdrawal. Pakistan lacks Oman's banking infrastructure for frozen-asset routing and carries its own regional stakes, making it a less structurally neutral broker for the Qatar-held $12 billion sequencing.

Kuwait

Kuwait invoked Article 51 of the UN Charter after absorbing an Iranian ballistic-missile strike on Ali Al Salem Air Base on 28 May, becoming the first Gulf state to make a formal individual self-defence claim in the war. The invocation creates a legal record enabling a future bilateral defence-pact activation without yet triggering it.

Oman

Oman denied any Hormuz toll plan within hours of Bessent's 28 May threat, absorbing a sanctions warning from the country it has brokered for since 1981. The rapid capitulation preserved the channel formally, but Tehran now knows Washington will threaten its own mediator, which changes Muscat's calculus on how far it can lean into any joint-management architecture.
