The IEA projects global oil supply at about 110.3 million barrels per day in 2027, roughly 5 million barrels a day more than its demand forecast. That's the figure Citigroup economists, led by Nathan Sheets, flagged on Thursday as a reason for caution, even though Brent traded near $78 a barrel. Their note said one wartime supply shock has eased after sharp stock draws this spring, but a possible production surge next year could flip the market back toward turmoil.

In a Citigroup briefing room on Thursday, economists led by Nathan Sheets framed the market shift as a move from acute scarcity toward an uncertain redistribution of supply, demand and stocks. Their note said lower prices have already reduced immediate inflationary pressure for households and import dependent economies, while energy intensive industries gained breathing room as retail fuel and wholesale crude eased.

Immediate relief, tangible data

The International Energy Agency reported on June 17 that global supply slumped to 94.5 million barrels per day in May, down 600,000 barrels per day month on month, and that observed global stockpiles fell sharply in May after another large draw in April. The IEA also recorded Brent around $78 and U.S. WTI near $75 on June 17 in the same report, a level Citigroup notes is far below the wartime spike that tightened markets earlier in the year.

Those numbers explain why households and firms felt some immediate relief. Higher pump and diesel prices were a strain on budgets and on energy intensive sectors, and the easing in spot crude has reduced that pressure. Citigroup explicitly framed the situation this way: "While one supply shock is abating, another one may be around the corner," the economists wrote in the Thursday note led by Sheets.

The IEA also cut its 2026 demand outlook by 700,000 barrels per day versus last month’s estimate, setting 2026 demand growth at 1.1 million barrels per day year on year. At the same time the agency said inventories have been drawn down since the conflict began, a concrete measure of how much global stocks tightened in recent months.

Why caution remains

At the same time the IEA warned of a near term swing the other way.

The agency projected supply could rise to about 110.3 million barrels per day in 2027, while demand might recover by only about 2 million barrels per day to roughly 105.3 million barrels per day, creating what the IEA called a big overhang in 2027. That potential rebound in output, if it materializes, could flip the market from tight to over supplied as blocked or curtailed supplies return.

Market commentary has showed the urgency around low inventory levels and short-term price dynamics.

Analysts have flagged that elevated fuel prices and shortages of refined products are already accelerating structural shifts in consumption, including faster electric vehicle adoption and lower gasoline use in some markets.

Some analysts estimate notable drops in gasoline demand in certain markets, a shift that could be permanent. That structural change would blunt the economic shock of any future sustained spike in crude prices by reducing the sensitivity of demand to price swings.

The combined picture from Citigroup, the IEA and market commentary is a market moving out of immediate wartime scarcity into a period of volatility driven by three moving parts: how quickly blocked or curtailed supplies return, how deeply demand patterns have shifted, and whether inventories are rebuilt or further depleted. Citigroup’s note and the IEA data together put those three variables at the center of the next phase of oil risk.

For now the pullback in spot prices has lowered short term inflationary pressure, but the economists at Citigroup cautioned that the easing is conditional. If production normalizes and exports from the Gulf resume on schedule, the IEA’s projections suggest a sizeable surplus could emerge in 2027. That prospect is the reason Citigroup stresses a guarded read despite the recent price retreat.
