Gulf Oil Flows Near Prewar Levels Even As Iran Ramps Up Attacks on Hormuz Tankers

Summarized by NextFin AI
  • Middle East crude exports recovered to 17.5 million barrels a day (98% of pre-war levels) in September, even as Iran escalated tanker attacks in the Strait of Hormuz to the highest weekly rate since the conflict began.
  • Brent crude averaged $114 a barrel in September, $23 higher than August, while the EIA raised its Q4 forecast to $105 a barrel, reflecting a risk premium rather than physical scarcity.
  • Refined product flows lag at only 58% of pre-war levels (3 million barrels a day) versus crude at 98%, keeping distillate prices elevated despite crude volume normalization.
  • Persian Gulf-China VLCC freight rates hit a record $1.035 million a day, roughly five times normal costs, as the market prices war risk into every barrel despite recovering supply volumes.

NextFin News - Middle East crude exports have climbed back to 98 per cent of pre-war levels, reaching 17.5 million barrels a day in September, even as Iran stepped up attacks on tankers in the Strait of Hormuz to the highest weekly rate since the conflict began. The juxtaposition captures the central tension of the oil market today: the physical supply chain has adapted to war, but the risk premium has not gone away.

Crude flows from the region are now running at volumes comparable to the twelve months before the US-Iran war started on February 28, according to estimates from JPMorgan Chase, Goldman Sachs Group and independent shipping trackers. Yet the price of Brent crude has not returned to calm. It averaged $114 a barrel in September, $23 higher than in August, and the US Energy Information Administration lifted its fourth-quarter forecast to $105 a barrel. The market is paying for uncertainty, not for scarcity.

That gap between volumes and prices is the story. Gulf producers have rebuilt an export machine around a closed chokepoint, using pipelines, alternative ports and ship-to-ship transfers. But the recovery is uneven, concentrated in crude rather than refined products, and it depends on a fragile logistics chain that Iran is actively targeting. The question for investors is whether this rebound is a durable adaptation or a temporary reprieve before the next escalation.

The Recovery in Numbers: Crude Is Back, Products Are Not

The arithmetic of the rebound is striking. JPMorgan analysts, including Natasha Kaneva, estimated in a September 29 note that Middle East crude exports reached 17.5 million barrels a day, or 98 per cent of pre-war levels, while flows of refined products such as diesel and gasoline were only 3 million barrels a day, or 58 per cent of pre-war levels. Overall crude-and-product flows stood at 89 per cent of 2025 levels on a recent ten-day average.

The Middle East's oil export arteries are flowing again. That is a remarkable recovery for a region still at war.

Goldman Sachs put Persian Gulf exports, including clandestine "dark" flows, at 23.3 million barrels a day over the same week, in line with the 2025 average, and said the global oil market was roughly balanced in September. Independent shipping trackers corroborate the direction: Kpler's seven-day moving average for Middle East crude exports reached 18.3 million barrels a day on September 30, compared with an average of about 18 million barrels a day in the twelve months before the war, while Vortexa separately estimated the 14-day average for crude and condensate at 18.6 million barrels a day. Roughly 40 per cent of those exports now bypass the Strait of Hormuz altogether, with much of the remainder transferred between tankers offshore rather than shipped directly through the waterway.

But the headline volume conceals a critical asymmetry. Crude is fungible and can be rerouted; refined products cannot. The 58 per cent recovery in gasoline, diesel and other distillates matters because the global market for middle distillates was already tight before the war, and it is why diesel prices have stayed elevated even as crude volumes normalize. A region can move crude through a pipeline; it cannot as easily reroute the complex refinery-to-consumer chains that feed Asia's trucking, shipping and farming sectors.

The recovery also rests on specific infrastructure that has itself come under fire. Saudi Arabia's East-West pipeline, which carries crude to Red Sea ports and bypasses Hormuz entirely, was damaged in attacks earlier this month. Flows have since been restored to about half their pre-attack level; before the damage, the conduit was shipping more than 5 million barrels a day via the port of Yanbu. The pipeline is not just a workaround, it is the single most important pressure valve in the Gulf export system, and its vulnerability is a live variable in the price of every barrel that leaves the region.

How the Gulf Worked Around a Closed Chokepoint

The mechanism behind the rebound is not a return to normalcy. It is a costly, improvised logistics architecture built on three pillars: pipelines, alternative ports and ship-to-ship transfers.

Saudi Arabia and the United Arab Emirates have long maintained pipelines that terminate outside the Gulf, Saudi Arabia's line to the Red Sea and the UAE's pipeline to the port of Fujairah on the Gulf of Oman. Analysts estimate that existing and planned bypass projects could add almost 4 million barrels a day of export capacity, while available alternative-route capacity is roughly 3.5 million to 5.5 million barrels a day. That is enough to absorb a meaningful share of the disruption, but not all of it: nearly 20 million barrels a day moved through Hormuz in 2025, so the alternative routes cover roughly a fifth to a quarter of normal throughput.

The UAE's experience illustrates both the adaptability and the cost. After the war began, UAE production fell from about 3.4 million barrels a day before the conflict to roughly 1.9 million barrels a day in March, a decline of nearly 44 per cent. Then, in June, output surged 80 per cent to 4.1 million barrels a day, an all-time high, as Abu Dhabi leaned on its Fujairah pipeline and capitalized on its departure from OPEC. The UAE officially left the cartel on April 28, effective May 1, ending 59 years of membership and freeing itself from output quotas that had held production about 30 per cent below its roughly 4.85 million-barrel-a-day capacity. Abu Dhabi National Oil Company is targeting 5 million barrels a day of capacity by 2027.

The timing of the exit is inseparable from the war. The conflict removed the practical constraint on UAE output, the Strait of Hormuz, while OPEC quotas remained a legal one. Leaving the cartel converted spare capacity into actual barrels. But capacity does not automatically become production, and the Fujairah route, while it bypasses the strait, remains within range of Iranian drones and missiles. The UAE's rebound is real, but it is not risk-free.

The third pillar, ship-to-ship transfers, is the most fragile. Exporters now run an elaborate system of shuttle tankers that move crude to larger vessels waiting outside the waterway, so that the biggest ships never enter the strait at all. This keeps volumes moving, but it adds time, cost and handling risk to every barrel. It is a workaround that works only as long as the ships willing to do it keep showing up.

The Escalation: Record Attacks, Record Freight Rates

Just as volumes approached pre-war levels, Iran intensified its campaign against shipping. Between September 28 and October 5, there were at least 12 attacks on oil, liquefied natural gas and liquefied petroleum gas tankers around the Strait of Hormuz, the highest weekly total since the war began. The UN's International Maritime Organization recorded at least nine verified incidents in the same period, surpassing the previous weekly peak of eight set in mid-July, and the UK's Maritime Trade Operations reported that the pace of attacks had increased in recent days.

The market's response was immediate and severe, in freight if not yet in crude volumes. The cost of carrying crude from the Gulf to China surged to a record. Baltic Exchange data put the Persian Gulf-China VLCC freight rate at about $1.035 million a day in mid-September, compared with prior all-time peaks near $200,000 in 2008 and 2020. The Saudi Arabia-China route passed $1.3 million a day, pushing freight to 25-30 per cent of the cost of Gulf crude, versus 1-3 per cent in normal conditions. The Gulf of Oman-China VLCC rate hit a record Worldscale 450, roughly $11.50 a barrel.

These rates are partly theoretical, a war-risk premium quoted by the few owners still willing to price a Hormuz transit rather than a working shipping lane, according to shipping analysts. Real cargo has shifted toward shuttle routes in the Gulf of Oman. But theoretical or not, the numbers reveal what the market is pricing: the cost of moving Gulf oil has roughly quintupled, and that cost ultimately lands in the price of crude.

Crude prices themselves have been volatile rather than directionally clear. Brent fell to $97.72 a barrel on October 6, down 2.6 per cent from the previous day, then rebounded to close at $104.28 on October 8 after Houthi missiles struck airports in Riyadh and Abha, killing three people and injuring 36. As of October 13, crude was trading near $92.50 a barrel, down about 8.7 per cent over the past month but still roughly 58 per cent higher than a year earlier. The message is consistent: the market treats each escalation as a spike, not a structural repricing.

Why the Market Is Pricing Fear Rather Than Shortages

The first-order effect of the Iran war was simple: less oil got out of the Gulf, and prices rose. The second-order effect is more subtle and more important for investors: the market has learned that Gulf producers can adapt faster than Iran can disrupt, so it is pricing the risk of disruption rather than the disruption itself.

This explains the apparent contradiction at the heart of the story. Volumes are back. Prices are not down. The reason is that the constraint has moved downstream, from the wellhead to the shipping lane. A pipeline can be repaired and a refinery's export schedule can be rerouted, but every tanker captain, insurer and charterer now demands a war premium for entering the Gulf, and that premium is embedded in every barrel. The bottleneck is no longer physical supply; it is the willingness of the global shipping fleet to absorb risk.

That dynamic creates a peculiar market structure. On one side, the Energy Information Administration estimates that shut-in production averaged 4.8 million barrels a day in September, down from 5.8 million in August and a peak of 10.9 million in May. Supply is coming back. On the other side, the agency raised its Brent forecast for the fourth quarter to $105 a barrel, $14 higher than the previous month's outlook, assuming flows remain constrained through the quarter. The forecast is not driven by today's barrels; it is driven by the probability that tomorrow's barrels do not arrive.

This is also why the refined-product gap matters more than the crude headline. If product recovery lags at 58 per cent while crude sits at 98 per cent, the market's tightness is concentrated exactly where inventories are thinnest and substitution is hardest. A second-order consequence of the war, then, is a persistent distillate premium that survives even a crude surplus.

The Counter-Thesis: This Time the Chokepoint Actually Bites

The strongest case against the adaptation narrative is straightforward: the bypass system has absorbed pressure so far only because Iran has chosen calibrated disruption over closure. The Strait of Hormuz remains the world's most important oil chokepoint, and Tehran has repeatedly signaled that it can escalate at will. If Iran moves from harassing tankers to sustained mining or blockade, the shuttle-and-pipeline architecture breaks down, because the alternative routes cover at most a quarter of normal Hormuz throughput and ship-to-ship transfers require a permissive security environment.

There is also a political trigger that the market is watching closely. For weeks, reports circulated that the United States could resume strikes on Iranian targets before the November 3 midterm elections. President Donald Trump explicitly rejected that timing on October 8, saying on Truth Social: "We will not be attacking Iran at any time prior to the Midterm Elections," and citing productive discussions with Tehran. That removed one near-term escalation risk. But it also telegraphed that escalation remains on the table after the vote, and the market discounts the post-election window accordingly.

The counter-thesis has a clear falsifying signal. If crude exports through and around the Gulf hold above 16 million barrels a day for four consecutive weeks while tanker attacks remain at or above 12 per week, the adaptation story is confirmed and the risk premium should compress. Conversely, if weekly exports fall below 14 million barrels a day, roughly 80 per cent of pre-war levels, for two consecutive weeks, the bypass system has reached its limit and the structural-shock scenario takes over.

Outlook: Three Horizons, Three Scenarios

Short term (weeks): Volatility dominates. Every attack headline moves freight rates and crude prices, but the direction depends on whether the attack is seen as isolated or as the start of a campaign. The October 8 pullback in the US strike timeline removed one catalyst; the November 3 election reopens it. The two real-time gauges are the weekly tanker-attack count and the seven-day export average.

Medium term (one to two quarters): The base case is that crude volumes continue to recover toward full pre-war levels while product flows lag, keeping distillate margins elevated. The Energy Information Administration's $105 fourth-quarter Brent forecast embeds this view, constrained but not broken. The upside case is a successful post-election escalation that temporarily closes the strait, pushing Brent toward the April-May highs above $100 a barrel. The downside case is a durable ceasefire that restores Hormuz traffic and lets Brent fall back toward the agency's fourth-quarter 2027 projection of $74.

Long term (structural): This is the crux of the investment question, and it requires separating two forces that the market tends to blend. The cyclical leg is clear: volumes are mean-reverting toward pre-war levels as security permits, and they will fall back if attacks intensify. The structural leg runs underneath it: the war has accelerated a permanent shift in Gulf export geography. Pipelines and Gulf of Oman ports will carry a larger share of Gulf crude even after the fighting stops, new bypass capacity comes online in 2027, and the UAE's exit from OPEC gives it the freedom to monetize capacity regardless of cartel discipline. If those changes survive the war, the Strait of Hormuz loses some, though not all, of its coercive power. That is a structural reduction in Iran's leverage and a structural increase in Gulf producers' resilience.

But that structural shift is not yet complete. It requires continued security cooperation with the US Navy and buyers willing to accept higher freight costs. Until then, the rebound is cyclical, a mean-reverting recovery in volumes built on improvisation rather than a permanent rerouting of global oil flows. The structural change is real, but it is only half-finished.

What to watch: the weekly count of tanker attacks in the Strait of Hormuz, where 12 attacks per week is the current ceiling; the seven-day export average, where 16 million barrels a day is the adaptation threshold and 14 million is the failure line; the status of Saudi Arabia's East-West pipeline, which carries 5 million barrels a day of bypass capacity at stake; and the US political calendar around the November 3 midterms. If attacks stay elevated while exports keep rising, the market's fear premium is overdone. If exports roll over while attacks accelerate, the rebound was a mirage.

The Gulf oil rebound is real, but it is priced like a ceasefire that has not been signed. Volumes say the war is manageable; freight rates say otherwise. Until one of those signals breaks, the market will keep paying a war tax on barrels that have already made it out of the Gulf.
