What Happened
- US President Trump stated on March 24, 2026 that negotiations with Iran to end the West Asia war were underway, asserting that Tehran "wants to make a deal so badly."
- The US transmitted a 15-point peace plan to Iran through intermediaries including Pakistan; key demands include a complete halt to uranium enrichment, cessation of support for militant proxies, and recognition of Israel's right to exist.
- Iran announced it would allow "non-hostile" oil vessels to transit the Strait of Hormuz — the first partial easing of the effective Hormuz blockade since the war began.
- Iran simultaneously denied it was in direct negotiations with the US, with officials characterising Trump's claims as intended to influence energy and financial markets.
- Israel continued military operations against Iran and Lebanon, having reportedly been caught off guard by the US diplomatic outreach.

The Strait of Hormuz — Geography and Strategic Significance
The Strait of Hormuz is a narrow maritime passage between the southern coast of Iran and the Musandam Peninsula of Oman, connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is the world's single most critical oil chokepoint, with no alternative pipeline network of comparable capacity.
- Location: Between Iran (north) and Oman (south); approximately 33 km wide at its narrowest navigable point
- Daily oil flow (pre-conflict 2025): approximately 20 million barrels per day (mb/d) — over 25% of global seaborne oil trade
- LNG transit: approximately one-fifth of global LNG trade passes through, mainly Qatar's exports to Asia and Europe
- Asian dependence: 82% of Hormuz oil flows to Asia; China, India, Japan, South Korea are the top four importers
- Before the 2026 conflict began: ~120 vessels transited daily on average; this fell to just 5 tracked vessels per day during peak disruption
- Two designated traffic lanes — one inbound, one outbound — each about 3.2 km wide within Omani waters
- There is no effective bypass: Saudi Arabia's East–West pipeline and the Abu Dhabi Crude Oil Pipeline (ADCOP) have a combined bypass capacity far below Hormuz volumes
Connection to this news: Iran's selective reopening of the strait to "non-hostile" vessels is a calculated diplomatic move — retaining leverage over global energy markets while signalling openness to negotiation. The partial reopening immediately softened crude prices in global markets.
Iran's Strategic Doctrine — Hormuz as a Deterrent
Iran has long held the Strait of Hormuz as its primary asymmetric deterrent against military attack. The Islamic Revolutionary Guard Corps Navy (IRGCN) maintains the capability to mine the strait, threaten tanker traffic with fast boats, and deploy anti-ship missiles from coastal positions. The actual use of this capability — even partially — marks a significant escalation.
- Iran has periodically threatened to close the strait since the 1980s Iran-Iraq War (1980–1988), during which "tanker wars" saw both sides attack oil shipping
- UN Convention on the Law of the Sea (UNCLOS), Article 38: All states enjoy the right of transit passage through international straits used for navigation; no state may suspend this right
- However, UNCLOS rules have limited enforcement capacity against a state that chooses to physically interdict shipping
- The IRGCN is designated as a foreign terrorist organisation by the US (2019); it controls the strait's defence
- International Maritime Organization (IMO) — the UN agency for shipping safety — has no military enforcement role; safety in contested straits falls to naval coalitions
- Combined Maritime Forces (CMF): US-led naval coalition operating in the Arabian Gulf region, including Combined Task Force 153 (Red Sea/Gulf of Aden) and CTF 152 (Persian Gulf)
Connection to this news: Iran's conditional reopening of the strait demonstrates its use of Hormuz control as a negotiating chip — confirming that the strait's status is now a central element in any US-Iran diplomatic settlement.
International Law and Freedom of Navigation
Freedom of navigation (FON) is a foundational principle of international maritime law under UNCLOS (1982). The US conducts Freedom of Navigation Operations (FONOPs) globally to assert this right against excessive maritime claims. A state physically blocking international shipping raises complex questions under international law regarding self-defence, use of force, and collective security.
- UNCLOS adopted: December 10, 1982 at Montego Bay, Jamaica; in force: November 16, 1994
- India ratified UNCLOS: June 29, 1995
- Article 38 (transit passage through straits): Guarantees all ships and aircraft the right of continuous and expeditious transit
- UN Charter Article 51: Allows use of force in self-defence; Iran's blockade could be framed as a defensive measure
- The US has not ratified UNCLOS (signed 1994, never ratified by Senate) but generally supports its navigation provisions
- Iran's "non-hostile vessel" criterion lacks definition in international law — effectively imposing a political test on commercial shipping that has no UNCLOS basis
Connection to this news: Iran's conditional passage declaration — requiring vessels to not be "associated with" the US or Israel — introduces a politicised screening mechanism with no basis in UNCLOS, complicating insurance, shipping, and legal liability for all flag states.
Key Facts & Data
- Strait of Hormuz daily oil throughput (pre-conflict): ~20 million barrels per day
- Share of global seaborne oil trade: over 25%
- Daily vessel transits: fell from ~120 to ~5 at peak disruption
- US peace plan: 15 points, delivered via Pakistan; key demand is complete halt to uranium enrichment
- Iran's partial reopening: "non-hostile" vessels may pass "in coordination with Iranian authorities"
- Vessels linked to US, Israel, or states supporting military action against Iran excluded from passage
- UNCLOS Article 38 guarantees transit passage rights through international straits — Iran's conditions have no UNCLOS basis
- IEA described the 2026 Hormuz closure as "the largest supply disruption in the history of the global oil market"
- Qatar's LNG exports — critical to Europe and Asia — also transit the Strait of Hormuz
