A small, little-known island off Iran’s southern coast has emerged as one of the most strategically important points in global trade.
Larak Island, positioned at the eastern entrance of the Strait of Hormuz, has effectively become a controlled maritime checkpoint — or what industry insiders are calling a “toll gate” — through which selected vessels are allowed to pass.
The shift marks a fundamental change in how one of the world’s most critical shipping lanes is operating.
According to the latest data from Lloyd’s List Intelligence on April 2, no vessels have transited the strait via its traditional route since March 15. Instead, traffic has been funnelled through a narrow corridor near Larak Island, overseen by Iran’s Islamic Revolutionary Guard Corps (IRGC).
Since March 13, at least 62 vessel transits have been tracked via this “Larak corridor”, signalling a clear operational shift rather than a temporary disruption.
The system functions as a vetting mechanism, according to energy expert and strategic advisor Felipe Germini, founder and managing director of GerminiEnergy who wrote a recent detailed post on the subject.
Shipowners must submit detailed cargo manifests, ownership structures, and destination information in advance. Approved vessels are then guided through Iranian territorial waters, where passage is confirmed by IRGC personnel on-site.
Those that do not comply — or are deemed unsuitable — are denied access.
“The strait is open: selectively,” Germini wrote. “This is not a blockade. This is a toll gate. And the difference matters enormously.”
He explained that the IRGC has effectively built a de facto approval system centred on Larak Island, where vessels are screened before being allowed through a tightly controlled shipping lane.
“The IRGC reviews the submission. If approved, the ship is directed through Iranian territorial waters via the Larak Island corridor, where personnel make visual confirmation before granting passage,” he wrote.
A $2m passage — and a new revenue stream
While not officially formalised, the system is already showing signs of monetisation.
One reported transaction suggests a vessel paid approximately $2m for a single transit through the corridor — a figure that, if standardised, could turn Larak into a significant revenue-generating node.
Germini noted that such pricing could unlock “hundreds of millions of dollars per month” if applied consistently across even a reduced volume of traffic.
At the same time, shipping through Hormuz has collapsed.
Preliminary data from Lloyd’s List Intelligence indicates traffic is down 94 per cent year-on-year in March, with just 211 verified cargo vessel transits recorded since 1 March 2026.
Two-tier market emerges
The implications are already rippling across global energy and shipping markets.
Data shows that 72 per cent of vessels transiting Hormuz since March 1 have some form of Iranian nexus — whether through ownership, flag, sanctions exposure, or operational links, according to Lloyd’s List.
This is creating what Germini described as a structural divide in the market.
“A Chinese refiner buying Iranian crude through the Larak corridor pays nothing in war risk insurance — the IRGC guarantees safe passage,” he wrote. “A European refiner trying to source Saudi crude through a contested strait pays significantly higher costs and may not get insured at all.”
War risk premiums have surged by 200–300 per cent, with some insurers withdrawing coverage for the region entirely.
The effective cost of moving oil through Hormuz has increased by an estimated $4 to $6 per barrel — adding billions of dollars in additional friction to global markets each month.
The emergence of Larak Island as a controlled gateway also signals a more calibrated strategy than a full closure of the Strait of Hormuz.
Rather than halting flows outright, Iran is selectively controlling access — allowing it to maintain pressure on global markets while preserving a degree of continuity in trade.
As Germini put it: “The cost differential is not a rounding error. It is a competitive weapon.”
Latest numbers (March 1 — April 1, 2026) on Strait of Hormuz traffic from Lloyd’s List:
