Oil Glut 2026: How Big Will It Be? Experts Weigh In on Oversupply & Price Impact (2025)

The oil market is on the brink of a crisis, and it’s not just about supply and demand—it’s about how much excess oil could flood the system, and no one seems to agree on the scale. For months, experts have been warning of an impending oil glut, but the question remains: how big will it be? And this is the part most people miss: the answer isn’t just about numbers; it’s about geopolitics, shifting trade routes, and the unpredictable nature of global economies. Let’s dive in.

The Looming Oversupply: A Complex Puzzle

The oil market has been bracing for a significant oversupply, with forecasters, investment banks, and analysts predicting that this glut could weigh heavily on prices by the end of this year and into early next. But here’s where it gets controversial: estimates range wildly, from a historic super-glut to more modest inventory increases during the traditionally weaker demand period in the first quarter. Why the disparity? Because the oil market is anything but straightforward. It’s a tangled web of supply, demand, geopolitical tensions, and speculative guesses—all laced with ‘ifs’ and ‘what ifs.’

The IEA Sounds the Alarm

The International Energy Agency (IEA) recently warned that the global oil oversupply could be larger than expected, driven by surging production in the Middle East and robust output from the Americas. In September alone, oil stored on water swelled by a staggering 102 million barrels—the largest increase since the pandemic. The IEA predicts that as this oil moves onshore to major hubs, crude stocks will surge, while natural gas liquids (NGLs) may decline. But just as the world was digesting this news, the U.S. threw a wrench into the works by sanctioning Russia’s top oil producers, Rosneft and Lukoil. Will these sanctions actually stick? Some analysts doubt it, given their role as leverage in U.S.-Russia negotiations over Ukraine.

The Sanctions Wild Card

Rosneft and Lukoil have been exporting about 3 million barrels per day (bpd), roughly 3% of global supply. Goldman Sachs expects the impact of sanctions to be limited, as OPEC has spare capacity to offset some of the shortfall. But here’s the kicker: trade networks often adapt quickly to sanctions, and countries like China and India are already scrambling to replace Russian barrels or find workarounds. Chinese state-owned giants like Sinopec and PetroChina have reportedly paused Russian oil purchases, but independent refiners may still seek Russian crude—albeit more cautiously. India, too, is treading carefully, especially as it seeks tariff reductions from the U.S.

The Glut’s Impact on Prices

The World Bank predicts the oil glut will expand significantly this year and rise to 65% above the 2020 high by next year. With slowing demand due to rising electric vehicle (EV) sales and stagnating oil consumption in China, Brent crude prices are expected to drop from $68 this year to $60 next year—a five-year low. OPEC+’s decision to pause production hikes in early 2026 makes sense in this context, but the U.S. sanctions on Russia add a layer of uncertainty. What if these sanctions disrupt Russian oil flows? That could shrink the expected surplus, giving OPEC+ a reason to rethink its production strategy.

OPEC’s Dismissal: A Case of Wishful Thinking?

Despite the warnings, OPEC and its key members, like the UAE, publicly dismiss the glut narrative. UAE Energy Minister Suhail Al Mazrouei insists there’s no oversupply on the horizon, citing solid demand. But OPEC+’s pause in production hikes tells a different story—one of caution to prevent a price slump if inventory builds accelerate. The pause also buys time to assess the impact of U.S. sanctions on Russian supply and global trade flows.

The Bigger Question: What’s Next?

As the oil market navigates this uncertainty, one thing is clear: the glut is coming, but its size and impact remain anyone’s guess. Will sanctions on Russia reshape global oil flows? Can OPEC+ maintain control in the face of shifting demand and geopolitical tensions? And what does this mean for oil prices in the long run? What’s your take? Do you think the glut will be as severe as some predict, or will the market find a way to balance itself? Let us know in the comments—this is one debate where every perspective matters.
