Crude oil and geopolitics: Physical premiums ease, but shipping risks threaten a fragile supply recovery
Brent futures rose 4.9% last week, closing at USD 109.86/bbl on Friday, their highest level since May. The rally came as attacks on shipping and Saudi infrastructure raised fresh concerns about Middle Eastern supplies. However, the physical market sent a different signal. Dated Brent fell sharply to USD 116.6/bbl on Friday, narrowing the gap with futures considerably. Tanker rates have also eased from record highs. While these developments offer some relief, the recovery in Middle Eastern exports remains fragile, inventories are depleted, and geopolitical risks continue to support prices.
Dated Brent was assessed at USD 134.1/bbl on Monday before easing to around USD 126.4/bbl on Thursday and USD 116.6/bbl on Friday. The more than USD 17/bbl decline during the week is significant. Dated Brent nevertheless remains above Brent futures, although the gap narrowed to less than USD 7/bbl on Friday. The benchmarks cover different delivery periods, but the sharp narrowing suggests some easing in the immediate physical tightness.
The premiums paid for individual cargoes earlier in the week illustrated just how tight the market had become. According to S&P Global/Platts, a Forties cargo traded on Monday at more than USD 19/bbl above Dated Brent for loading in early November. A WTI Midland cargo for delivery into Rotterdam traded at more than USD 22/bbl above Dated Brent. These premiums apply to the relevant pricing periods and should not simply be added to the same day's Dated assessment. The subsequent decline in Dated Brent suggests that some of this exceptional pressure has eased.
Tanker rates tell a similar story. Shipping crude from the US Gulf Coast to China recently cost around USD 40/bbl, making long-distance crude movements extremely expensive. Rates declined somewhat during the second half of the week as tanker demand softened, but remain close to record highs. High freight costs still favour crude located closer to the buyer and limit the ability to move oil between regions.
For refiners, the combination of expensive physical crude and elevated freight costs continues to squeeze margins, even when product cracks against Brent futures appear attractive. The IEA expects global refinery runs to reach a seasonal low of 81.3 mb/d in October. We see a risk that high feedstock costs and shipping constraints limit the production response to high diesel prices. The market needs more refined products, but not all refiners can benefit from the exceptionally high product prices.
Meanwhile, the recovery in Middle Eastern exports is becoming increasingly fragile. Attacks on commercial shipping have intensified further. UKMTO reported two additional tanker attacks in the northern Arabian Gulf on Friday, while another incident involving an LNG tanker was reported off Yemen on Saturday. The escalation has also spread to Saudi infrastructure. Houthi attacks have targeted Saudi Aramco facilities, while Saudi forces intercepted a ballistic missile heading towards Yanbu on Friday. No damage to the port's oil infrastructure was initially reported. Yanbu is particularly important because it provides an alternative export route to Hormuz.
Bloomberg also reported that at least ten empty VLCCs and several Suezmax tankers had stopped or turned away while approaching Fujairah. This matters because ship-to-ship transfers outside Hormuz have helped sustain exports. If larger tankers stay away, that system becomes less effective. Iran does not need to close the strait completely to disrupt supplies.
The IEA's October report illustrates the vulnerability. Global oil demand is forecast to fall by 2.6 mb/d in 2026, but observed inventories were still 509 million barrels below end-February levels at the end of September. Onshore stocks fell by 113 million barrels during September, largely offset by an increase in oil at sea. Oil in transit provides less immediate protection against local shortages. As the chart below illustrates, oil demand also picks up seasonally in Q4, although the IEA expects consumption to remain substantially below last year's level.
The latest US figures also showed an 8.6 million barrel draw in crude inventories, while distillate stocks declined by another 2.5 million barrels. Lower imports and hurricane-related production disruptions contributed to the crude draw, so it should not be read solely as a sign of stronger demand. Washington has also offered up to 17 million barrels of crude from the Strategic Petroleum Reserve through an exchange programme.
Washington is considering easing sanctions on some vessels in the Russian and Iranian shadow fleets to increase available tanker capacity. No general decision has been made. We doubt this would provide substantial relief. Many of these vessels are already operating, while their age, condition, insurance constraints and remaining European restrictions would limit their wider use.
On Sunday, Iran reiterated that its proposal to reopen Hormuz within seven days remains on the table. However, negotiations remain stalled over sanctions relief, the US blockade and Iran's nuclear programme. We maintain our view that a lasting US–Iran agreement before the November midterms is unlikely. Our central scenario remains a more durable reopening of Hormuz in Q2 2027.
The sharp decline in Dated Brent and easing freight rates are encouraging signs, but we would caution against interpreting them as evidence that the supply crisis is over. Weaker demand and financial market volatility can push prices lower in the short term. However, depleted inventories, continued shipping disruptions and the risk of further attacks on Saudi infrastructure leave the market exposed to renewed price increases.
