IEA Raises Alarm Over Oil Oversupply as OPEC+ Increases Output
The International Energy Agency (IEA) has issued a cautionary assessment of the global oil market, warning that supply is rising sharply—at a pace far exceeding demand. In its latest monthly report, the IEA projects global supply will increase by 2.5 million barrels per day (bpd) in 2025, a notable revision from its earlier estimate of 2.1 million bpd. For 2026, the agency anticipates an additional 1.9 million bpd in supply.
At the heart of this uptick lies a strategic decision by OPEC+—which includes the Organization of the Petroleum Exporting Countries, Russia, and other allies—to expedite the rollback of output cuts. This unexpected acceleration in production, combined with growing output from non-OPEC producers such as the U.S., Canada, Brazil, and Guyana, has further tilted the supply-demand balance.
Demand Forecast: Sluggish and Underwhelming
On the demand side, the outlook is notably less optimistic. The IEA now expects global oil demand to rise by just 680,000 bpd in 2025 and 700,000 bpd in 2026. These figures represent downward revisions of 20,000 bpd each from prior forecasts and are significantly below OPEC’s own estimate of a 1.29 million bpd demand increase for this year alone.
“The latest data show lacklustre demand across the major economies and, with consumer confidence still depressed, a sharp rebound appears remote,” the IEA noted. The agency attributes this stagnation to both economic uncertainty—exacerbated by policies like President Donald Trump’s tariffs—and an ongoing structural transition toward renewable energy sources, which the IEA believes is progressing faster than many in the industry expect.
A Bloated Market: Implied Surplus Nears 3 Million bpd
The mismatch between surging supply and stagnant demand has led the IEA to forecast an implied surplus of nearly 3 million bpd in 2026. This excess supply could place sustained downward pressure on prices unless counterbalanced by unexpected disruptions or policy interventions.
Indeed, Brent crude prices dropped below $66 per barrel following the release of the IEA report—highlighting market sensitivity to the mounting oversupply. Despite robust production figures, geopolitical uncertainties such as U.S. sanctions on Iran and the European Union’s revised price caps on Russian oil may inject volatility, potentially constraining supply from two of the world’s largest producers.
“It is clear that something will have to give for the market to balance,” the IEA said, underscoring the systemic tensions currently unfolding in the energy landscape.
Refining Runs Set New Records
Interestingly, even as demand remains muted, refining activity is breaking records. The IEA forecasts global crude oil refining rates to reach 85.6 million bpd in August 2025, surpassing the July figure of 84.9 million bpd and setting a new high. Looking ahead, refinery runs are expected to rise by 670,000 bpd in 2025 and by a further 470,000 bpd in 2026, buoyed by unexpectedly strong performance from OECD nations and China.
This surge in refining is likely connected to strategic stockpiling efforts, particularly in China, where institutional and policy measures have focused on bolstering energy security. These stockpiles have helped absorb some of the current surplus, providing temporary relief to price pressures.
Structural Shifts Underway
Beyond the short-term metrics, the broader narrative is one of structural transformation. The IEA’s more conservative demand projections reflect its belief in an accelerating global shift toward decarbonization and alternative energy sources. This transition challenges traditional market dynamics and introduces new strategic variables for producers, investors, and policymakers alike.
As supply continues to rise and demand flattens, questions remain about how the industry will adapt. Will further OPEC+ adjustments be required? Can geopolitical tensions or environmental policy drive a course correction?
For now, the world oil market is on a trajectory toward oversupply, and stakeholders will need to act decisively to prevent further imbalance.
