The global oil market is set to enter 2026 with a comfortable surplus that is expected to weigh on prices, even as analysts warn of deeper structural challenges looming later in the decade. New projections from Oxford Economics indicate Brent crude could finish 2026 at around $58 per barrel and ease to roughly $55 in 2027, well below prevailing market expectations. The forecasts are anchored in a sustained supply surplus projected to exceed 2 million barrels per day.
Global production is expected to rise by about 1.6 million barrels per day next year, bringing total output to around 106 million barrels per day. Demand is forecast to increase at a slower pace, climbing to 104 million barrels per day in 2026. The supply outlook has been lifted by stronger US shale performance and faster progress on major developments in Brazil. Despite lower rig numbers and expectations of West Texas Intermediate trading below $55, improvements in drilling efficiency are allowing US production to grow by approximately 400,000 barrels per day.
Latin America continues to play an important role in the supply picture. Brazil and Guyana are set to add a combined 1.6 million barrels per day across 2025 and 2026. OPEC is projected to restore nearly 1 million barrels per day in the second half of 2026 as key members, including Saudi Arabia and the UAE, start trimming back voluntary cuts.
On the demand side, growth is expected to slow to around 600,000 barrels per day next year, led mainly by emerging markets and OPEC economies. Consumption in advanced economies is forecast to level off due to efficiency improvements and rising electrification. China remains a central driver, supported by manufacturing and petrochemical activity, while demand in the United States is expected to decline structurally.
Against this backdrop of near-term abundance, some analysts are drawing attention to risks that could arise in the next decade. Ole Hansen, Head of Commodity Strategy at Saxo Bank, said current prices may not support the level of upstream investment needed to offset natural declines in existing fields. He noted global fields lose between 6 million and 8 million barrels per day each year, requiring roughly $500 billion in annual investment just to maintain today’s output levels.
Hansen warned that the industry may face a supply shortfall early in the 2030s if investment continues to lag. He pointed out that Saudi Arabia and the UAE remain the only major producers with meaningful spare capacity, while US shale growth is showing signs of slowing.
The International Energy Agency recently revised its long-term outlook, now projecting oil demand to grow well beyond 2040. The shift heightens concerns that delays in investment could lead to sharper price increases later.
Analysts say risks to the 2026 outlook cut both ways. A faster slowdown in US shale, renewed OPEC restraint or geopolitical disruptions could push prices higher, while a larger-than-expected surplus early next year could trigger steeper price drops.
Despite the near-term softness, the debate over long-term supply needs is intensifying. Some analysts warn that postponing investment today could set the stage for tighter markets later in the decade.
