Gulf Oil Exports Return to Pre-War Levels Amid Hormuz Disruptions

Gulf crude exports rebound to pre-war volumes

Data released for September show that Gulf crude shipments have risen to the average recorded before the 2020 Iran‑Iraq conflict. The United States Energy Information Administration reports an average of 6.5 million barrels per day, a level that had not been seen since early 2020.

Exporters attribute the recovery to a combination of strategic rerouting and increased reliance on ship‑to‑ship (STS) transfers that allow cargoes to bypass the Strait of Hormuz altogether.

Alternative routes and ship-to-ship transfers

Since the escalation of attacks on tankers in the Hormuz corridor, many operators have shifted to longer but safer passages. The most common alternatives include:

• Transiting the Red Sea and the Bab el‑Mandeb strait before entering the Indian Ocean.
• Using the Cape of Good Hope as a detour for vessels bound for Europe.
• Routing through the Persian Gulf’s northern ports and then conducting STS transfers in international waters.

The International Energy Agency notes that STS operations have grown by roughly 30 percent since the first attacks were reported, providing a flexible method to move oil without entering contested waters.

These transfers typically occur near offshore platforms or in designated anchorage zones where two vessels can connect safely. The practice reduces exposure to piracy and missile threats while maintaining a steady flow of product to refineries worldwide.

Iranian oil shipments remain constrained

Despite the overall rebound, Iranian crude exports have not returned to their pre‑war average. The Organization of the Petroleum Exporting Countries cites a monthly output of about 1.8 million barrels per day, well below the 2.5 million barrels per day recorded before 2020.

Sanctions, limited access to international financing, and the continued risk of tanker attacks have forced Iran to rely on smaller vessels and regional markets, limiting its ability to compete for long‑haul contracts.

Geopolitical implications for the Strait of Hormuz

The surge in alternative routing highlights the strategic importance of the Strait of Hormuz. Recent missile strikes on commercial tankers have prompted several navies to increase patrols, and the United Nations Security Council has called for an urgent review of maritime security measures in the region.

While the increased use of STS transfers and distant routes eases pressure on the narrow waterway, it also raises operating costs for exporters and importers alike. Shipping companies report higher fuel consumption and longer transit times, factors that can translate into higher prices for end consumers.

Market reaction and price trends

Oil benchmarks have reflected the shifting dynamics. Brent crude rose modestly in early September, reaching $84 per barrel, while West Texas Intermediate settled around $80 per barrel by the end of the month.

Analysts attribute the price movement to a balance between the restored Gulf supply and the added logistical expenses of longer routes. A typical price impact can be summarized as follows:

1. Higher freight rates for vessels avoiding Hormuz.
2. Increased insurance premiums for ships operating in high‑risk zones.
3. Potential supply gaps if further attacks disrupt the limited remaining traffic through the strait.

Overall, the market remains cautious, with traders monitoring both the security situation and the willingness of Iranian producers to increase output under current constraints.

As the Gulf region adapts to the new security environment, the reliance on alternative pathways and STS transfers is likely to become a permanent feature of the global oil supply chain. The resilience demonstrated by exporters this month suggests that, despite ongoing threats, the flow of energy from the Middle East can continue to meet worldwide demand.
