The global oil market approaches 2026 with differing scenarios: a short-term surplus that suggests softer prices and a long-term supply issue that might spark volatility later in the decade. Oxford Economics predicts Brent crude will close 2026 around $58 per barrel, dropping to $55 in 2027—below market expectations—due to a consistent surplus exceeding 2 million barrels per day (mbpd). This surplus is driven by strong supply growth, anticipated at 1.6 mbpd next year, raising global production to about 106 mbpd, while demand grows more slowly to 104 mbpd.
This supply boost is due to unexpected resilience in US shale and quicker development of Brazilian projects. Despite declining rig counts and West Texas Intermediate (WTI) prices expected below $55, productivity improvements and longer laterals are allowing US output to grow by approximately 400,000 barrels per day. Latin America is a notable contributor, with Brazil and Guyana adding around 1.6 mbpd throughout 2025–26. OPEC plans to gradually lift production cuts in the second half of 2026, contributing nearly 1 mbpd, mostly from Saudi Arabia and the UAE.
In terms of demand, Oxford Economics forecasts a slowdown to 600,000 bpd in 2026, focusing on emerging markets and OPEC nations, while consumption in advanced economies levels off due to efficiency gains and electrification. China continues to drive demand, supported by manufacturing and petrochemicals, despite accelerating EV adoption. Conversely, US demand is expected to decline structurally.
This short-term abundance contrasts with the long-term outlook highlighted by Ole Hansen, Head of Commodity Strategy at Saxo Bank. “At first glance, supply appears adequate,” Hansen notes. “Inventories have increased, demand growth has cooled, and parts of the curve trade with enough softness to keep macro-focused traders at ease. But beneath that surface lies a deeper structural tension: the world still needs substantial new oil supply well into the coming decades, and current price levels likely won’t incentivize it.”
Hansen warns that the market is underestimating the relentless depletion of existing fields — 6–8 mbpd annually — which requires about $500 billion annually to maintain current output. “Effectively, the global industry must replace a ‘new Saudi Arabia’ every couple of years just to keep production steady,” he says. Without ongoing investment in upstream projects, the industry may face a supply crunch by the early 2030s.
Spare capacity offers limited comfort. “Saudi Arabia and the UAE remain the only major producers able to increase output quickly, and both are now operating near their expanded capacity levels,” Hansen explains. US shale — the world’s “just-in-time” supplier — is showing signs of plateauing, with growth of 360,000 bpd in 2025 unlikely to recur. “If WTI remains below $60 another year, US production could flatten or decline,” Hansen cautions.
The International Energy Agency’s recent revision of long-term demand projections underscores the urgency of this investment challenge. Oil consumption is now expected to rise well beyond 2040, possibly nearing 2050, reversing earlier predictions of a pre-2030 peak. Hansen summarizes the dilemma: “The market must choose between two paths. It can allow prices to firm gradually — supporting drilling, upstream expansion, and long-cycle projects needed over the coming decade — or risk much sharper price increases later as scarcity becomes the dominant driver.”
Risks to the 2026 outlook are two-sided. Upside risks include a faster-than-expected US shale slowdown, Russian export disruptions, or OPEC restraint, which could tighten balances and raise prices. Downside risks, though less likely, are more significant: a larger surplus could lead to rapid inventory builds in Q1, causing sharper price corrections. Broader geopolitical shifts — such as resolving the Russia-Ukraine conflict or political changes in Venezuela — could also add barrels to the market.
Bottom line: 2026 might feel like a year of plenty, with Brent prices in the high $50s, but future tightness is being seeded. As Hansen warns, “Delaying investment only amplifies future tightness. The earlier the price signal appears, the lower the eventual peak is likely to be.”
