Iran war closes Strait_of_Hormuz

The near-total closure of the Strait of Hormuz has caused significant supply shortfalls and economic strain, impacting major importing nations and revenue-starved Gulf producers like Iraq and Kuwait. The adoption of stealth measures by tankers, while providing some relief, creates an opaque and fragmented energy market, making it harder to gauge benchmark pricing and increasing insurance premiums for shipowners.
The Strait of Hormuz has been nearly totally closed for over four months due to a conflict involving Iran and the United States, stranding over 13 million barrels of oil per day. This has forced Gulf producers like Iraq and Kuwait to shut down oilfields and refineries, leading to supply shortfalls globally. While official traffic remains low, tankers are increasingly adopting 'dark' mode, switching off satellite tracking systems to transit the strait, with Vortexa estimating 65% of outbound laden tankers used this method in May. This opacity distorts market visibility, though 'oil on water' levels in the Gulf have dropped, indicating increased outflows. Iran is allowing limited volumes through bilateral arrangements with Asian governments such as Pakistan, India, China, and Japan, and is seeking to implement a tolling system, which could further reshape global oil trade. The market faces a fragmented and dangerous reality, with a full return to normalcy unlikely even with a political breakthrough.
