Key takeaway

Seven VLCCs gathered at Chabahar on 20 April while only three vessels transited the strait the same week.

Windward detected seven Very Large Crude Carriers (VLCCs, the standard two-million-barrel oil tankers that carry Gulf crude) near Chabahar on Iran's Makran coast on 20 April⁠¹. Chabahar is Iran's only deep-water port on the Arabian Sea and sits east of the geometry Admiral Brad Cooper's narrower port-interdiction order covers. The same Windward log counted three strait transits the day before, a fraction of the 135-per-day pre-war baseline and the lowest count since the blockade began.

Earlier mid-transit reroutings from India to Chinese ports ahead of the OFAC General License U lapse established the Chabahar-routing adaptation; seven VLCCs at anchor there indicate the same workaround now running at capacity. The USS Spruance's firing into the Touska's engine room earlier in the same window hardened the Hormuz risk premium on the kinetic side, but the structural story is sideways: vessels avoiding the strait do not need the strait reopened to clear cargo.

Deep Analysis

In plain English

The US Navy has been blocking oil tankers from using the strait of Hormuz, the narrow sea passage through which most Gulf oil normally flows. Iran has responded by loading oil onto tankers at a different port, Chabahar, which sits on Iran's other coastline , the Arabian Sea side , and has no connection to the strait at all. Windward, a maritime tracking company, spotted seven large tankers near Chabahar on 20 April. Only three vessels transited the strait in the same period. This matters because it shows the blockade has not stopped Iran from shipping oil , it has just changed which port the oil leaves from. Chabahar is operated under a 2016 agreement with India, which adds a political complication: any US attempt to block Chabahar would directly affect India's interests.

Deep Analysis

Root Causes

CENTCOM's written blockade order was drafted around the strait of Hormuz and Iranian Gulf ports, reflecting the operational assumption that Iranian crude exports require the strait. Chabahar sits on the Makran Coast, outside the Gulf, accessible from the Arabian Sea without any Hormuz transit.

The legal gap was present from the order's inception: Iran never ratified UNCLOS, leaving its domestic maritime law , updated in 2024 to claim jurisdiction over 'hostile-linked vessels' , as the operative legal text on the Iranian side, while the US order covers only Iranian-port traffic rather than the full territorial sea.

India's 2016 Chabahar agreement, originally designed to give Delhi access to Afghan and Central Asian markets bypassing Pakistan, created an operational control structure that places Chabahar partially inside Indian sovereign jurisdiction, complicating any US enforcement action.

What could happen next?

Consequence
Chabahar routing at capacity would reduce the blockade's supply-disruption component while leaving the kinetic risk premium intact, potentially splitting the oil price signal into two separable factors.
Short term · 0.72
Risk
Any CENTCOM attempt to extend interdiction to Chabahar creates a direct India-US collision over India's 2016 operational rights agreement with Tehran.
Medium term · 0.78
Precedent
The Chabahar bypass establishes a template for sanctions evasion at ports outside written enforcement geometry, applicable to any future blockade scenario.
Long term · 0.8

Source Landscape

This story draws on neutral-leaning sources from Israel

Israel

Primary parallel: During the 1973 Arab Oil Embargo, Saudi Arabia and Iraq routed exports overland via the Trans-Arabian Pipeline (Tapline) and the Iraq-Turkey pipeline to bypass tanker interdiction risk in the Gulf of Suez. The embargo's price effect was sustained not because all physical flow stopped but because the diversion routes lacked the throughput to replace lost Gulf volume , the same arithmetic now being tested at Chabahar.

Counter-parallel: In 1984 Iraq began the 'tanker war' phase of the Iran-Iraq conflict specifically because Iran had identified and was exploiting Kharg Island's offshore loading capacity as a bypass around Iraqi interdiction.

Iraq's response , attacking Kharg Island itself , escalated the conflict rather than closing the bypass. The 2026 situation differs in one critical respect: Chabahar is Indian-operated under a 2016 bilateral agreement, making a direct CENTCOM strike against the port a three-way diplomatic incident.

Seven VLCCs near Chabahar represent approximately 14 million barrels of potential lift capacity at the VLCC standard of 2 million barrels each. Even at 50% utilisation and a single loading cycle per week, the route could sustain 7 million barrels per week of Iranian crude flow , roughly 1 million barrels per day.

Brent's refusal to settle below $96 across five consecutive sessions reflects the market pricing the kinetic risk premium at Hormuz, not the physical supply gap. If Chabahar throughput scales to even 500,000 bpd, the price signal loses its supply-disruption component and becomes a pure risk premium , a structurally different and easier-to-exit pricing regime.

Consensus view: IISS maritime analyst Nick Childs and Kpler's head of tanker analytics Homayoun Falakshahi both conclude that seven VLCCs at Chabahar demonstrate the blockade has displaced rather than halted Iranian crude exports: the physical flow continues through a port outside CENTCOM's written enforcement geometry, meaning the price signal is being sustained by kinetic risk and insurance withdrawal, not by physical interdiction.

Counter-view: The Russian Institute of World Economy notes that Chabahar's infrastructure constraints , single deep-water berth, limited storage, Arabian Sea swell exposure , cap throughput at roughly 300,000 barrels per day even at maximum utilisation, well below the 1.8 million bpd Iran was exporting before the war, so the route is a partial relief valve rather than a blockade-replacement.

Key tension: Whether the Chabahar routing is already large enough to break the price signal that underpins the blockade's coercive logic, or whether CENTCOM will be forced to extend interdiction geometry east into the Arabian Sea , a move requiring additional force posture and risking direct India confrontation.

This Event

Seven VLCCs at Chabahar, three at Hormuz

Iranian crude is leaving through a port outside CENTCOM's written enforcement geometry while Hormuz legitimate traffic collapses to 2 per cent of its pre-war baseline.

Led to

Five vessels, no AIS: Hormuz goes dark

The all-dark AIS transit day on 23 April advances the dark-fleet dominance pattern documented by Windward on 19-20 April (ID:2671), where only 3 transits were recorded and 7 VLCCs were held near Chabahar.

Different Perspectives

Council on Foreign Relations

CFR's analysis identified 18.75% of the 48-team field facing access barriers — the only available quantification after the State Department admitted it has none. The explicit contrast with South Africa 2010's visa waiver for all ticket holders positions the US as a regressive host by historical standards.

New York commuters / Assemblyman Bhalla

Bhalla framed Penn Station's closures as a class issue: 'For the 99 percent that can't afford to attend the games, it would be nice to at least know how you're going to get home from work.' Eight closures lock 650,000 daily commuters out for tournament traffic, with one on a Monday rush hour.

French Football Federation

The FFF called an 11:00 CEST press conference for 28 July, at its Paris headquarters, following an extraordinary executive committee meeting, at which Zinedine Zidane is expected to be presented as head coach succeeding Didier Deschamps. As of this writing no communique confirms the appointment, contract length or start date.

Morocco

Morocco is pushing for the 2030 final at its Grand Stade Hassan II in Casablanca, a planned 115,000-seat venue that would be the world's largest football stadium on completion. The venue is contested by a Spanish petition for the Santiago Bernabeu, and FIFA has fixed neither the venue nor the tournament's proposed 64-team format.

FIFA

FIFA's first tournament report, published 27 July, itemises nearly 300,000 accredited personnel, 73,700 security staff and 300,000 square metres of custom-grown turf, with no revenue or cost figure attached. As a Swiss association answering to its own Congress rather than a treasury, FIFA has followed the same operational-before-financial sequence it used after Qatar 2022.

Javier Tebas / La Liga

La Liga president Javier Tebas said on 21 July that FIFA's system is rotten from the root and that Gianni Infantino's time as president has, in his words, concluded. Tebas has no vote in FIFA's process, so days after the IOC declined jurisdiction over a separate ethics complaint, he used the only instrument he has.
