The oil market at the dawn of 2026 is facing a complex mix of geopolitical upheavals and shifting supply dynamics that could significantly influence prices and market stability. But here's where it gets controversial: many analysts wonder whether these tensions and fluctuations are temporary blips or signals of deeper structural changes in global energy supply. Let’s explore what’s happening and what it might mean for the future.
The start of this year was marked by heightened geopolitical tensions centered around Iran and Venezuela, introducing fresh uncertainties regarding their ongoing ability to export oil. In the early weeks of January, Brent crude prices surged by approximately $6 per barrel, reaching around $66/bbl, though by now, the price has eased slightly to about $64/bbl. This spike reflects market nervousness fed by fears of potential disruptions. However, the situation remains fluid.
Both Iran and Venezuela have seen their oil exports decline even prior to these recent tensions. Iranian shipments, for example, fell by 350,000 barrels per day from October’s recent peak, settling at about 1.6 million barrels daily in November and December. This decline has caused significant amounts of Iranian crude to accumulate at sea, creating a backlog. Similarly, Venezuelan exports have plummeted from 880,000 barrels per day in December to roughly 300,000 barrels per day in early January. This sharp drop is largely due to the U.S. blockade targeting sanctioned tankers that transit to and from Venezuela.
Meanwhile, Russia’s oil industry has shown a surprising resilience. Despite ongoing attacks on its energy infrastructure, Russian refineries ramped up operations in December, leading to a monthly crude output increase of 550,000 barrels per day—reaching a 33-month high. Nonetheless, the financial gains from these higher exports are being eroded by widening discounts on Russian crude and refined products, which reduced export revenues to about $11 billion in December—roughly half of what they were before Russia’s invasion of Ukraine. Additionally, aggressive drone strikes in the Black Sea and Caspian Sea regions have further disrupted Kazakhstani oil supplies and exports.
While it’s still early to determine the full impact of these geopolitical tensions on global oil markets, the current excess supply appears to be providing a buffer that keeps prices relatively stable. Interestingly, despite recent volatility, benchmark crude prices are still about $16 per barrel lower than they were a year ago. This decline is largely driven by a substantial oversupply accumulated over the past year, confirming earlier forecasts.
Global oil inventories increased significantly in 2025—by approximately 470 million barrels, averaging about 1.3 million barrels per day. This increase was evident across various indicators: rising stocks at sea, higher crude inventories in China, and increased supplies of natural gas liquids in the U.S. The most notable jump occurred in November, when worldwide inventories grew by 75 million barrels, or 2.5 million barrels per day, with additional increases likely continuing into December. For instance, China’s inventory levels rose after new import quotas were introduced, which helped offset steep declines in stocks across several Middle Eastern producer countries toward the end of the year.
This sizeable surplus was fueled by a substantial increase in oil production, which began at the start of 2025. Non-OPEC+ countries contributed nearly 60% of the total growth of about 3 million barrels per day. Saudi Arabia has spearheaded the increase among OPEC+ nations following the end of production-cut agreements, while the United States, Canada, Brazil, Guyana, and Argentina have dominated growth among non-OPEC+ producers. Provided there are no major disruptions—if OPEC+ maintains its current output policies and U.S. shale activity doesn’t decline sharply—the global supply could expand by another 2.5 million barrels per day in 2026.
This anticipated growth, combined with the large accumulated inventories, creates a considerable buffer that could surpass actual demand, which itself is forecasted to increase by about 930,000 barrels daily in 2026. The question remains: how long can this oversupply continue without reversing market fundamentals? And what will that mean for prices and geopolitical stability in the oil-exporting regions? These are debates worth watching as the year unfolds—and as tensions and market dynamics continue to evolve.
