## Market Overview
The Strait of Hormuz traffic market through May is priced at 0.5% YES for May 15 and 9.5% YES for May 31. Strait of Hormuz maritime transit market shows 46% YES for 20 vessels by May 31. US Invasion of Iran Market is 28.5% YES for before 2027.
## Key points to remember
– Iran’s extensive control over the Strait of Hormuz appears consistent with a lower likelihood of normal traffic resuming by May 15. – The new administrative measures suggest the continued reduction of ship transits, which will impact the probability of passage of 20 ships by May 31. – Increasing geopolitical tensions could indicate a moderate increase in the possibility of a US military response before 2027.
## Article body
Iran has officially expanded its definition of the Strait of Hormuz, significantly increasing the area it claims to control. The move is part of a broader strategy to assert administrative and regulatory authority over this critical maritime chokepoint, which facilitates a substantial portion of global oil and LNG trade. Iran’s Revolutionary Guard Corps (IRGC) has stressed that it will not tolerate any perceived encroachment on its newly defined waters. The announcement comes amid an ongoing conflict between Iran and the US-Israeli coalition, which began with airstrikes and the assassination of Iran’s supreme leader. The conflict led to Iran’s de facto blockade of the strait, affecting global energy markets.
## Market interpretation
The expansion of Iran’s zone of control in the Strait of Hormuz favors a NO outcome for the market, which forecasts normal traffic levels by May 15. This development has a significant impact, because it institutionalizes the blockade rather than easing it. The establishment of a new transit approval system also suggests continued restrictions on vessel movements, which will impact the likelihood of reaching 20 transits by the end of May. Geopolitical tensions could indicate a moderate increase in the likelihood of a US invasion before 2027, reflecting increased regional instability.
## What to watch
Observers should monitor any further announcements from the Iranian government or the IRGC that could strengthen or relax control measures on the Strait of Hormuz. Additionally, any diplomatic developments between Iran and the US-Israeli coalition could alter the current trajectory of this conflict. Key dates include upcoming deadlines for traffic normalization by May 15 and 31. Changes in US military posture or statements from the Pentagon could also provide insight into potential escalation in the region.
