Crude oil outflows from the West Asian Gulf have rebounded to their pre-conflict baseline of 16.5 million barrels per day (mbd), effectively restoring seaborne export volumes despite maritime blockades and ongoing hostilities across the Strait of Hormuz. Data compiled by maritime trade intelligence firm Kpler reveals that regional producers—excluding Iran—have adapted their logistics architecture through overland bypass pipelines terminating on the Red Sea and Gulf of Oman, alongside high-seas shuttle tanker operations.
Key takeaways
- Complete volume recovery: Crude oil leaving the Gulf region between September 1 and September 28, 2026, averaged at least 16.5 mbd, matching pre-war baseline volumes and rebounding from a low of 10.5 mbd recorded during the initial conflict escalation in March.
- Overland pipeline bypasses: While 83% of regional crude historically traversed the Strait of Hormuz, 40% of September export volumes bypassed the chokepoint via overland pipelines across Saudi Arabia and the United Arab Emirates.
- Surging alternative terminal flows: Saudi Aramco increased loadings through its East-West Petroline to the Red Sea port of Yanbu from 0.8 mbd pre-war to 4.3 mbd, while the UAE expanded outflows through the Abu Dhabi Crude Oil Pipeline (ADCOP) to Fujairah from 1.1 mbd to 2.7 mbd.
- Shuttle tankers and STS transfers: For the 60% of oil that continues to transit Hormuz, operators have abandoned direct long-haul tanker voyages in favor of localized shuttle runs, with over 70% transferring crude ship-to-ship (STS) offshore in the Gulf of Oman.
- Persistent refined fuel deficit: Although crude export volumes have normalized, downstream refined products—including diesel, jet fuel, and liquefied natural gas (LNG)—remain supply-constrained, maintaining upward pressure on global crack spreads and retail fuel prices.
How Gulf crude exports recovered despite a closed chokepoint
The Strait of Hormuz, a 21-mile-wide maritime channel separating Iran from Oman and the UAE, historically handles roughly one-fifth of the world’s petroleum consumption. When direct conflict erupted in early 2026, maritime transit through the waterway contracted, stranding commercial vessels, elevating war-risk insurance premiums, and dropping regional crude outflows to 10.5 mbd in March.
However, rather than waiting for formal diplomatic or military resolution of the waterway’s passage rights, major Gulf Cooperation Council (GCC) producers and international charterers reorganized the physical routing of Persian Gulf petroleum.
According to tracking data and market analysis authored by Emmanuel Belostrino, head of global crude and geopolitical market data at Kpler, export volumes across September climbed back to the pre-war norm of 16.5 mbd. The mechanism enabling this recovery relies on two logistical pivots: inland pipeline diversions and decentralized maritime transshipment hubs.

Overland pipeline bypasses: Yanbu and Fujairah
The structural pillar supporting the volume recovery is the expanded utilization of existing strategic overland pipelines. Before the regional conflict, roughly 83% of the Gulf’s crude departed via tankers loading inside the Persian Gulf and transiting Hormuz. By September, 40% of the region’s total crude outflows left without touching the strait.
Two primary conduit systems made this bypass possible:
1. Saudi Arabia’s East-West Crude Oil Pipeline (Petroline)
The 1,200-kilometer Petroline connects Saudi Aramco’s processing facilities at Abqaiq in the Eastern Province to the King Fahd Industrial Port at Yanbu on the Red Sea coast.
- Pre-war operations: Yanbu was primarily used for domestic refining supply and marginal European exports, loading approximately 0.8 mbd.
- Conflict redirection: Aramco prioritized maximum throughput across the dual-line system, boosting loadings at Yanbu to 4.3 mbd by mid-2026. This allowed Saudi light and heavy crude to reach Asian and European refiners through the Red Sea and Suez corridors without passing near Iranian-controlled shorelines.
2. The UAE’s Abu Dhabi Crude Oil Pipeline (ADCOP)
Operated by the Abu Dhabi National Oil Company (ADNOC), ADCOP links the onshore Habshan oilfields in Abu Dhabi directly to the deepwater port of Fujairah, situated outside the Strait of Hormuz on the Gulf of Oman.
- Capacity mobilization: Prior to the conflict, ADCOP handled approximately 1.1 mbd of Murban crude.
- Current output: Loadings at Fujairah expanded to 2.7 mbd, operating near the pipeline’s nameplate capacity of 1.5 mbd with augmented drag-reducing agents (DRA) and expanded intermediate offshore storage buffers.
Combined, Yanbu and Fujairah have allowed Saudi Arabia and the UAE to divert 7.0 mbd of production around the maritime chokepoint.
| Export Route / Pipeline Mechanism | Pre-War Loading Volume | Current Loadings (Sept 2026) | Primary Destination Hub | Chokepoint Status |
| Saudi Petroline (to Yanbu, Red Sea) | 0.8 mbd | 4.3 mbd | Asia, Europe via Suez | Bypasses Hormuz Entirely |
| ADCOP Pipeline (to Fujairah, Gulf of Oman) | 1.1 mbd | 2.7 mbd | India, East Asia | Bypasses Hormuz Entirely |
| Hormuz Shuttle Tankers (STS Transfers) | 13.5+ mbd (direct transit) | ~9.5 mbd (shuttle links) | Transferred offshore Oman | Traverses Hormuz via Shuttles |
| Total Regional Crude Outflow (excl. Iran) | ~16.5 mbd | 16.5 mbd | Global Refineries | 100% Volume Normalized |

The shuttle-tanker and offshore transshipment mechanism
While pipelines absorbed 40% of total export volumes, the remaining 60% (approximately 9.5 to 9.9 mbd)—originating from Kuwait, southern Iraq (Basra terminals), Qatar, and northern Saudi offshore fields—lacked direct pipeline bypasses to open oceans.
To extract these barrels, maritime operators overhauled conventional logistics:
- Short-haul shuttle transits: Instead of deploying international Very Large Crude Carriers (VLCCs) directly into Persian Gulf ports—where insurers demanded steep war-risk surcharges or refused coverage outright—operators deployed smaller, specialized shuttle tankers.
- Nighttime convoys and escort lanes: Shuttle vessels operate within coordinated transit corridors, moving rapidly through the narrowest stretches of the strait before returning for reloading.
- Offshore Ship-to-Ship (STS) Transfers: Analysis from Kpler shows that over 70% of the crude transiting Hormuz in August and September transferred cargoes to larger ocean-going VLCCs offshore in the Gulf of Oman, safely outside the immediate conflict zone.
Once transferred in deep waters off the Omani and UAE coasts, standard international tankers transport the consolidated barrels to long-distance destination ports in Asia and Europe, shielding global tanker operators from entering hazardous waters.
Strategic petroleum releases and the refined product bottleneck
The restoration of crude export volumes has provided relief to international benchmark pricing, aided by coordinated government interventions. The International Energy Agency (IEA) confirmed that member countries have released 325 million barrels of crude and oil products from public strategic petroleum reserves (SPR), out of 400 million barrels pledged during emergency meetings in March.
However, energy analysts caution that the headline recovery in crude volumes obscures ongoing structural imbalances:
The refined fuel deficit
Crude export pipelines can transport unrefined heavy and light crudes, but they do not solve the disruption of complex downstream refining complexes situated inside the Persian Gulf:
- Diesel and aviation turbine fuel (ATF): Mega-refineries located inside the Gulf (such as Ruwais, Jazan, and Al-Zour) remain constrained in exporting finished middle distillates due to maritime container and clean-tanker shortages.
- Elevated crack spreads: The shortfall in direct product exports has kept global refining margins and wholesale diesel prices elevated, even as crude prices stabilized.
The LNG lag
Liquefied natural gas cannot be pumped through standard crude oil pipelines. While QatarEnergy managed to restart limited LNG sailings under naval convoy monitoring in late September—with tracking showing cargoes like the Milaha Qatar and Al Gharrafa clearing the strait to offload at import terminals like Hazira in India—overall LNG transits remain at roughly 25% of pre-conflict volumes.
Implications for India’s energy security and refining margins
For India, the world’s third-largest oil consumer and importer of over 85% of its crude requirements, the restoration of Gulf export volumes provides crucial macroeconomic stability.
- Supply continuity for coastal refiners: State-owned refiners (Indian Oil, Bharat Petroleum, Hindustan Petroleum) and private operators (Reliance Industries’ Jamnagar complex and Nayara Energy) depend on West Asian grades—such as Arab Light, Basrah Medium, and Upper Zakum—for baseline slate blending. The expansion of loadings at Fujairah and Yanbu allows Indian buyers to lift crude with shorter voyage durations and reduced insurance exposure.
- Geographical proximity to Fujairah: With Fujairah situated along the Gulf of Oman, the maritime transit route to India’s western ports (Mundra, Sikka, Vadinar, and Mumbai) bypasses the contested strait entirely. Indian tankers can complete round trips within four to six days, ensuring stable inventory replenishment.
- Moderating domestic import bills: When the conflict peaked in March and crude flows collapsed to 10.5 mbd, rising freight rates and soaring Brent spot prices threatened India’s current account deficit and inflation trajectory. The normalization of supply to 16.5 mbd has checked speculative price spikes, providing price predictability for domestic fuel retailers.
What to watch next
- Infrastructure durability at Yanbu: Pumping 4.3 mbd continuously through Saudi Arabia’s Petroline tests the limits of pumping stations and storage tank capacity at Yanbu. Any maintenance downtime or operational disruptions along the Red Sea coast will immediately impact export volumes.
- Insurance premium adjustments: Marine underwriters continue to assess whether shuttle-and-STS configurations represent a permanent reduction in commercial risk or an ad-hoc stopgap. Adjustments to war-risk premiums for Persian Gulf calls will dictate the cost overhead for Asian refiners.
- Winter LNG demand: As European and North Asian heating demand accelerates toward the final quarter of the year, the inability of pipeline networks to bypass Hormuz for LNG will shift market focus from crude availability to natural gas constraints.
Frequently asked questions
Has the Strait of Hormuz been reopened to normal commercial traffic?
No. Commercial navigation through the Strait of Hormuz remains restricted and subject to elevated security protocols. What has changed is how oil is routed: producers are bypassing the strait using overland pipelines to the Red Sea and Gulf of Oman, while the remaining crude is moved using shuttle tankers and offshore ship-to-ship (STS) transfers.
Which countries operate the pipelines bypassing the Strait of Hormuz?
Saudi Arabia operates the East-West Crude Oil Pipeline (Petroline) from its Eastern Province to the Red Sea port of Yanbu, and the United Arab Emirates operates the Abu Dhabi Crude Oil Pipeline (ADCOP) from Habshan to the port of Fujairah on the Gulf of Oman.
How much oil leaves the Gulf through pipelines compared to ships?
In September 2026, approximately 40% (around 7 mbd) of total Gulf crude exports bypassed the Strait of Hormuz through overland pipelines terminating at Yanbu and Fujairah. The remaining 60% transited the strait via dedicated shuttle tankers.
Why are fuel prices and diesel still high if crude supplies have recovered?
While unrefined crude oil has found alternate routes through pipelines, finished petroleum products (such as diesel, gasoline, and jet fuel) and liquefied natural gas (LNG) cannot easily traverse these crude pipeline networks. Reduced clean-tanker movements and constrained refinery exports from within the Gulf continue to pressure refined product markets.
