Japanese tanker Idemitsu Maru attempts Strait of Hormuz crossing amid ceasefire

The Japanese tanker Idemitsu Maru is trying to navigate the Strait of Hormuz, according to shipping data. The market on Strait of Hormuz traffic returning to normal by the end of May sits at 15% YES.

The 15% price suggests some traders are betting on selective easing of transit restrictions for non-Iranian vessels. The attempt comes during a fragile ceasefire extension brokered by Pakistan and China, which could allow more commercial traffic if it holds. Volume for this market is $0 face value, pointing to limited conviction behind the current pricing.

Sub-markets for countries sending warships through Hormuz by April 30 are at 1.2% YES, unchanged from yesterday but down from 12% a week ago. Commercial traffic may see some normalization, but military maneuvers look unlikely in the near term. The US escorting commercial ships through the strait by April 30 is at 1.1% YES, with traders skeptical about US military escort involvement.

The Strait of Hormuz traffic sub-market has no trades to report. With this kind of thin liquidity, even a small order could move the odds substantially, making this a high-risk environment for anyone considering a position.

The Idemitsu Maru’s attempt is one data point, not a trend. For these odds to move meaningfully higher, traders would need to see consistent increases in commercial traffic or official announcements easing restrictions. At 15¢, a YES share pays $1 if traffic returns to normal by the end of May, a 6.67x return, but that requires the ceasefire to hold and more vessels to follow Idemitsu Maru’s path.

Watch for statements from IRGC Navy Commander Alireza Tangsiri or changes in daily vessel transits tracked via MarineTraffic data. A confirmed rise in transits or a statement lifting restrictions would be the clearest catalysts for price movement.
