Key Takeaways
- Kpler has transitioned its reporting methodology to focus on Gulf of Oman net exports rather than individual tanker listings to better capture complex ship-to-ship (STS) transfers.
- Middle East oil flows remain severely constrained, with Strait of Hormuz transits down approximately 92% to 95% from pre-conflict levels, averaging only 5-6 vessels per day.
- HFI Research reports a global oil market deficit of 3 million to 4 million barrels per day (b/d), with the Oman lane currently handling roughly 4 million b/d of the remaining regional transit.
- Inventory levels in the Middle East are currently estimated at 263 million barrels, which is roughly 100 million barrels below the peak seen in May 2026.
Kpler has implemented a significant adjustment to its oil flow tracking methodology, moving away from traditional tanker-by-tanker listings in favor of a Gulf of Oman net export model. This change is designed to improve data accuracy by accounting for "dark" activity and the increasing frequency of ship-to-ship (STS) transfers that occur without confirmed load terminals.
The new methodology specifically tracks offshore Gulf of Oman net exports, excluding direct terminal loadings to provide a clearer picture of total Hormuz clearance. This adjustment address the "shuttle tanker" phenomenon, where vessels load at Gulf terminals, transit the strait with transponders off, and transfer cargo to larger vessels in the Gulf of Oman.
Market analysts from HFI Research have praised the move, noting that it provides a more reliable "flow sheet" for navigating the current supply deficit. According to recent data, the Oman lane remains the primary artery for regional exports, transiting approximately 3.9 million to 4 million b/d, with contributions from Iraq (1.5 million b/d), UAE (1 million b/d), and Kuwait (0.8 million b/d).
Despite these adjustments, the physical disruption in the region remains stark. Kpler data indicates that commodity vessel traffic through the Strait of Hormuz has collapsed to just five to six ships per day, compared to a pre-war average of over 100 vessels. This sustained disruption has shifted global oil balances into a deep deficit, even as Chinese demand remains a primary "ceiling" preventing a more aggressive rally in Brent crude prices.
