France and Japan pay Iran's toll

Two G7 nations paid Iran in yuan to transit the Strait of Hormuz, breaking the collective coalition posture Washington built.

Key takeaway

The US-led coalition is fracturing as allies pay Iran for passage in Chinese currency.

CMA CGM Kribi, a Malta-flagged container ship owned by France's CMA CGM (the world's third-largest container line), became the first Western European vessel to transit the Strait of Hormuz since 28 February. It paid Iran's toll in yuan. Before entering Iranian territorial waters, the ship changed its AIS designation to "Owner France", signalling nationality for the IRGC's sorting mechanism.⁠1

Hours later, Mitsui OSK Lines' LNG carrier Sohar LNG crossed in ballast, the first Japanese-affiliated vessel to transit. Three Omani ships also passed through. The toll system charges $1 per barrel for oil tankers or roughly $2 million flat for container ships, payable in yuan or stablecoins.

France and Japan are nominal US allies. Both coordinated with Iranian maritime authorities. Both implicitly accepted Tehran's sovereignty claim over the strait, the precise claim Trump's 6 April energy deadline threatens force to break. Both paid in yuan, not dollars. The Philippines cut its own bilateral deal two days earlier. The coalition posture Washington has relied on since the blockade began is dissolving into bilateral licensing arrangements administered by Tehran.

Deep Analysis

In plain English

France and Japan are close US allies. On 4 April, their shipping companies paid Iran a fee in Chinese currency to sail through the strait of Hormuz. This matters for two reasons. First, they implicitly accepted Iran's right to charge for use of an international waterway. Second, they paid in yuan, not dollars, chipping away at US financial influence. The Philippines cut a similar deal two days earlier. the Alliance the US built around Hormuz is dissolving one bilateral arrangement at a time.

Deep Analysis
Root Causes

France's CMA CGM faces existential commercial pressure: the world's third-largest container line cannot absorb indefinite Hormuz closure without route restructuring at scale.

Japan's LNG dependency on Gulf supply creates energy-security vulnerability that outweighs diplomatic solidarity costs. Both governments calculated that collective posture imposed costs their economies could not sustain, while defection imposed only reputational costs the US would absorb rather than escalate over.

What could happen next?
  • Precedent

    Yuan payment for Hormuz passage creates a non-dollar settlement precedent for strategic waterway access that will outlast this conflict.

    Long term · High
  • Consequence

    Each bilateral deal reduces the political viability of US military action to reopen Hormuz, as enforcement would require overriding arrangements US allies have themselves accepted.

    Short term · High
  • Risk

    General License U expiry on 19 April could force a confrontation with France and Japan if Treasury declines to renew, criminalising transactions both nations have already completed.
