Brent climbed to $91.35, regaining a supply premium that had diminished in the previous week. Both figures reflect delayed public quotes MarketWatch futures data.

The more significant action is seen along the curve. October WTI was priced $12.09 higher than June 2027, representing a 16.2% premium.

Backwardation gives higher value to prompt barrels over future supply. This indicates traders are concerned about delivery risks right now, rather than a lasting shortfall.

On Sunday, U.S. forces targeted missile launchers located on Iran’s Larak Island. Following this, Iranian media reported that Iran launched attacks on two U.S. air bases in Jordan, with the information referenced by Reuters.

The key indicator is tanker movement. An ongoing blockage, a damaged loading terminal or an attack on a tanker would constrain immediate supply. Uninterrupted shipping could swiftly eliminate the geopolitical premium The Wall Street Journal.

The U.S. Energy Information Administration reports that average production shut-ins in July reached 5.5 million barrels per day. The agency also states global stockpiles declined by 4.2 million barrels daily over the second quarter.

EIA forecasts a further daily inventory drop of 3.8 million barrels for the third quarter. The agency’s baseline scenario sees Brent crude averaging close to $85 during this period, before falling to $78 in the fourth quarter as supply rebounds EIA outlook.

Upside potential is capped by demand. According to a Reuters survey of 31 analysts, Brent is projected to reach $85.08 in 2026, while WTI is seen at $80.20. Forecasts for global demand indicate a contraction ranging from one million to 1.6 million barrels per day.

China remains the main downside risk. Crude imports in July dropped 24.3% from a year ago. OPEC+ is set to add 188,000 barrels per day in September.

Risks: An intensification of military conflict may lift prompt contract prices and increase backwardation. Conversely, a shipping deal, steady tanker movements, or reduced demand from China could swiftly undo these gains.

The key indicator to monitor is the October-June spread. A broader differential would indicate a tightening in prompt supply, while a smaller spread would suggest that physical flows are returning to normal.

Transmission map

Key test: physical flows. A lasting tanker blockage or damaged loading terminal widens backwardation. Continued passage through Hormuz removes the premium faster than headlines alone.
Higher oil → inflation pressureHigher oil → airline and freight costsBackwardation → inventory draw incentiveWeak China → capped upside

Scenario watch

EscalationTanker or terminal disruption; prompt contracts rise fastest.
Base caseRestricted flows persist; Brent holds around the high $80s.
NormalizationShipping agreement and restored output pull Brent toward EIA's $78 fourth-quarter view.
Demand shockFurther Chinese weakness compresses the curve despite supply risk.
