An oil market under high tension

Since the start of 2026, the oil market has oscillated within a remarkably narrow range — between $80 and $92 for Brent — despite exogenous shocks that could have triggered far larger moves. This apparent stability conceals significant structural tensions that the OPEC+ meeting in October will bring back into focus.

On the supply side, Saudi Arabia has maintained voluntary cuts of 1 million barrels per day since mid-2023, bringing the kingdom’s production to approximately 9 million barrels/day — its lowest level in years. Riyadh is playing a delicate game: defending a price floor around $85 (necessary for Saudi Arabia’s budget equilibrium, estimated at $82/barrel for 2026) while avoiding stimulating US shale production, which becomes economically very attractive above $90.

On the demand side, China — the world’s largest crude oil importer — is sending contradictory signals. The stimulus package announced in September 2026 supports expectations, but actual consumption data remains 400,000 barrels/day below IEA projections. Europe, in slight recovery, and the United States, in a soft deceleration, complete a picture of global demand that is growing, but more slowly than potential supply if OPEC+ were to open the taps.

The October meeting: a defining moment for OPEC+

The next ministerial meeting of the OPEC+ Joint Ministerial Monitoring Committee (JMMC), scheduled for early October, is drawing market attention. Three options are on the table, each carrying very different implications for the barrel price in Q4 2026 and beyond.

Option 1 — Status quo: Saudi Arabia extends its voluntary cuts through end-2026. This is the most probable scenario (estimated at 50% by our allocation committee), as it preserves political consensus within the cartel while supporting prices. Brent would remain in the $82-92 range.

Option 2 — Tightening: Faced with rising non-OPEC production (US, Brazil, Guyana) and Chinese demand below expectations, some members could advocate for additional cuts of 500,000 to 800,000 barrels/day. This would push Brent toward $95-105. Probability: 25%.

Option 3 — Fracture: Countries such as the UAE or Iraq — whose production capacity exceeds their assigned quotas — could begin opening the taps, signaling crumbling internal discipline. A supply excess of 1 million barrels/day would be enough to push Brent down to $68-75. Probability: 25%.

Three probabilistic scenarios for Q4 2026

Our analysis integrates OPEC+ variables, global demand dynamics and geopolitical risks to build three scenarios covering the vast majority of possible trajectories. Each scenario is assigned a probability and its allocation implications.

Implications for wealth management portfolios

The oil question is not simply about taking a directional position on the barrel. For a wealth management investor, energy fits into a broader reflection on inflation hedging, sector diversification and correlation management within a multi-asset portfolio.

Risks and catalysts to monitor

Beyond the October meeting, four exogenous variables can substantially alter the Brent trajectory through year-end. Monitoring them is an essential part of active commodity allocation management.

Middle East geopolitics: Any escalation involving the Strait of Hormuz — through which approximately 21 million barrels per day transit, representing 21% of global consumption — would trigger an immediate spike toward $110-120/barrel. The geopolitical risk premium remains abnormally low (estimated at $3-5/barrel), leaving little room for error if the situation deteriorated.

Dollar and Fed policy: As oil is priced in dollars, any significant appreciation of the greenback — linked to a more restrictive Fed stance — mechanically weighs on dollar-denominated prices, and vice versa. The US midterm elections in November 2026 also represent a political uncertainty factor likely to generate volatility on the DXY.

Real Chinese demand: Monthly data from Chinese refineries is the best leading indicator of actual demand. A figure above 14.5 million barrels/day would constitute a strong bullish signal; below 13.5 million, the bearish scenario would become dominant.

US shale production: The Baker Hughes rig count (number of active drilling rigs) stagnates at 483 units, 15% below 2022 levels. If Brent sustainably breaks $92-95, an acceleration in drilling could add 400,000 to 600,000 barrels/day by mid-2027, naturally capping the market.
