Global Oil Demand Growth Poised for Significant Slowdown in H2 2025, IEA Warns
The global oil market faces a noticeable deceleration in demand growth during the latter half of 2025, following a robust performance in the first quarter. This shift, primarily driven by mounting economic headwinds, has been highlighted by the International Energy Agency (IEA) in its latest monthly assessment, providing crucial insights for energy investors monitoring market dynamics.
Between January and March, global crude consumption surged by an impressive 990,000 barrels per day (b/d) year-on-year. However, the IEA projects a marked slowdown for the remainder of the year, with growth rates expected to taper to a more subdued 650,000 b/d. The Paris-based agency, a key advisor to major global economies, underscored that the initial three months of the year will likely represent the peak quarter for demand expansion in 2025, signaling an emerging trend of faltering consumption.
Economic Pressures and Crude Price Volatility
This anticipated slowdown in demand growth presents a fresh challenge for crude prices, which have already experienced significant volatility. Last month, Brent futures briefly plunged to a four-year low amidst escalating global trade tensions initiated by President Donald Trump and a simultaneous announcement from OPEC+ regarding plans to increase output. While Brent has since recovered somewhat, trading near $65 a barrel as some trade-related fears receded, the underlying economic fragility remains a key concern.
Toril Bosoni, head of the IEA’s oil industry and markets division, articulated this perspective in a recent interview, stating, “We are observing clear indications that both the global economy and, consequently, oil demand growth are losing momentum.” The agency’s report further elaborated that heightened trade uncertainty is expected to exert downward pressure on worldwide economic activity, translating directly into reduced oil demand. Particularly concerning are the weaker-than-anticipated oil delivery figures from key emerging economies, notably China and India, which are typically major engines of global energy consumption.
Downgrade for US Shale and Looming Supply Surplus
The prevailing market conditions are also taking a toll on oil producers. The IEA has revised down its projections for the U.S. shale industry for the second consecutive month, attributing this adjustment to lower crude prices. This includes a significant downward revision of 190,000 b/d for 2026, indicating a more tempered outlook for one of the world’s most dynamic supply sources.
Despite this reduction in American drilling forecasts, the IEA predicts that the expansion of new global supplies will continue to outpace demand growth both this year and next. This imbalance is set to create a substantial global surplus, with inventories projected to swell by as much as 2 million b/d during the first quarter of 2026. Such an inventory build-up typically exerts significant downward pressure on crude prices, a critical factor for investors to consider.
OPEC+ Strategy and Market Impact
The potential for an even larger market glut hinges significantly on the production decisions of the Organization of the Petroleum Exporting Countries and its allies (OPEC+). The coalition has already announced output increases totaling 411,000 b/d for May and June – a volume three times greater than initially scheduled. This move is largely seen as an effort by Saudi Arabia, the group’s de facto leader, to penalize members that have previously exceeded their agreed-upon production quotas.
While Saudi Arabia has signaled the possibility of further surges, the IEA’s current calculations for the global supply-demand balance assume that OPEC+ will maintain a steady production level after June. The coalition is slated to review its output strategy during a video conference scheduled for June 1. Should OPEC+ choose to ratify additional production hikes beyond June, the rate at which global inventories accumulate could accelerate considerably, exacerbating the anticipated market surplus and intensifying pressure on commodity prices.
For investors, the confluence of slowing demand, persistent supply growth, and the strategic maneuvering of OPEC+ paints a complex picture for the oil market. Careful monitoring of economic indicators, trade policy developments, and OPEC+’s future decisions will be paramount in navigating the evolving landscape of crude oil investments.
