What Happened
- A Lloyd's List Intelligence report revealed that the Islamic Revolutionary Guard Corps (IRGC) has established a tightly controlled shipping corridor through Iranian territorial waters in the Strait of Hormuz, channelling approved vessels through a narrow 5-mile channel between the islands of Larak and Qeshm.
- Vessels seeking transit are required to undergo a multi-step vetting process: shipping companies must contact IRGC-linked intermediaries, submit documentation (ship ID, ownership papers, cargo manifest, destination, and crew details), and agree to IRGC escort.
- Lloyd's List tracked more than 20 ships using the emerging route, mostly Greek-owned tankers alongside Indian-, Pakistani-, and Chinese-linked vessels; one tanker reportedly paid $2 million for the right to transit.
- Iran officially denied imposing tolls, with Iranian officials calling the reports "false and fabricated," but acknowledged an escort arrangement for "non-hostile" vessels.
- India, Pakistan, Iraq, Malaysia, and China are reportedly in direct talks with Tehran to regularise transit arrangements, effectively legitimising Iran's de facto control over one of the world's most critical waterways.

IRGC Naval Control and Iran's Territorial Waters Strategy
The IRGC Navy (as distinct from the regular Iranian Navy/Artesh) has primary operational responsibility for the Persian Gulf and Strait of Hormuz. IRGC naval doctrine exploits Iran's geographic control of the strait's northern coastline and islands (particularly Larak, Qeshm, and Abu Musa) to create chokepoints within the international waterway. By routing vessels through its own territorial waters — rather than the internationally recognised shipping lanes — Iran sidesteps the UNCLOS transit passage guarantee (Articles 37–44) and substitutes it with Iranian-controlled "innocent passage" terms, which allow more regulatory discretion.
- IRGC Navy jurisdiction: Persian Gulf, Strait of Hormuz (while regular navy covers deeper waters)
- Key Iranian islands controlling the strait: Qeshm, Hormuz, Larak, Abu Musa (disputed with UAE)
- Larak-Qeshm corridor width: approximately 5 miles — a dramatic narrowing from the 21-nmi minimum width of the broader strait
- IRGC designated as Foreign Terrorist Organization (FTO) by USA: April 2019
- Iranian territorial sea claim: 12 nautical miles from baseline (UNCLOS standard)
- Legal tension: IRGC escort requirement and toll imposition contradict UNCLOS transit passage provisions; Iran and the US are non-signatories to UNCLOS
Connection to this news: The IRGC's territorial corridor strategy is a deliberate legal-operational manoeuvre — by routing ships through Iranian territorial waters rather than the international shipping lanes, Iran gains leverage to impose vetting, escort, and potentially toll requirements that it cannot apply under international law to the strait's transit passage zone.
Maritime Insurance and Freedom of Navigation
Lloyd's List Intelligence and Lloyd's of London are the global standard-setters for maritime insurance and risk assessment. When Lloyd's designates an area as a high-risk zone ("Listed Areas" or "Joint War Committee" areas), vessel operators face sharply higher insurance premiums, often making voyages economically unviable without government backing or risk-sharing arrangements. The Strait of Hormuz has historically carried a war-risk premium that fluctuates with regional tensions. The IRGC toll and vetting system introduces an additional layer of sovereign risk and legal uncertainty — payments to an FTO-designated entity could expose shipping companies to secondary sanctions under US law.
- Lloyd's List Intelligence: part of Lloyd's of London market, world's oldest insurance market (established 1688)
- Joint War Committee (JWC): Lloyd's body that designates high-risk maritime zones and sets war-risk premiums
- War-risk premium on Strait of Hormuz during 2019 tanker attacks: spiked to 0.5% of vessel value per trip
- IRGC FTO designation (US): April 2019 — creates legal exposure for any entity making payments to IRGC
- Secondary sanctions risk: companies paying IRGC tolls may face US Treasury (OFAC) sanctions
- Freedom of Navigation Operations (FONOPS): US Navy conducts these to assert transit passage rights against excessive maritime claims
Connection to this news: The $2 million toll claim, if accurate, puts tanker operators in a difficult legal position: pay and risk US secondary sanctions, or refuse and risk losing the passage entirely — with no viable alternative route that doesn't add weeks to the voyage.
Chokepoint Economics and Global Supply Chain Disruption
Maritime chokepoints create "geographic rents" — the economic surplus extractable from controlling a narrow passage through which trade must flow. The Strait of Hormuz's closure or restriction has historically transmitted immediately into global oil price spikes (Brent crude rose ~15% in the first days of the 2019 tanker incident; the current crisis has sent prices even higher). Beyond oil, the strait carries LNG exports from Qatar (the world's largest LNG exporter) to Asian markets. Chokepoint disruption has cascading effects: higher freight costs raise input costs across manufacturing, transport, and agriculture; insurance disruptions reduce trade volumes; and diversification (Cape of Good Hope rerouting) adds 2–3 weeks and proportionate fuel costs.
- Strait of Hormuz: ~20–21 million barrels/day of oil equivalent in normal times (~20% of global petroleum trade)
- Qatar LNG exports: ~100–110 million tonnes/year — predominantly transit Hormuz to Asia
- Cape of Good Hope alternative: adds ~2–3 weeks per voyage; significantly higher fuel and operational costs
- Brent crude price sensitivity: Hormuz disruption scenarios typically modelled at $10–$30/barrel price impact
- India's LNG import dependence through Hormuz: ~54% of total LNG imports
- Shipping cost escalation (Baltic Dry Index movements) affects India's trade balance directly
Connection to this news: Iran's monetisation of Hormuz passage converts a geopolitical weapon into a revenue stream — even for "friendly nations," the regime imposes economic friction on global trade, effectively extracting a sovereignty premium from every barrel of oil that passes through the strait.
