Brent oil price forecast (September, 2026)

The Applied Economics Research Centre (AERC) continues to monitor Brent crude oil price dynamics. In its latest report, OPEC revised the forecast for oil demand growth: lowered to 0.4 million b/d for 2026 and raised to 2.4 million b/d for 2027; the forecast for global supply remains unchanged.

The IEA expects global oil supply to decline by 5.7 million b/d in 2026 and to recover further by 8.0 million b/d in 2027. The demand growth forecast was corrected from the previous report.

In August, global oil supply fell by 1.6 million b/d to 100.1 million b/d amid continued supply disruptions and elevated geopolitical risks. At the same time, OPEC+ countries increased crude oil production by 297 thous. b/d to around 38.1 million b/d. The largest production increases were recorded in Iraq and Kazakhstan, while Iran and Russia posted the largest declines. Global observed oil stocks fell by a further 95 million barrels in August.


Oil prices remained highly volatile. At the time this report was prepared, Brent crude was trading at around $105.8/bbl, while prices ranged from $95.2/bbl to $108.8/bbl during the period under review. The rise in prices was driven by tighter supply due to disruptions in the Middle East and Russia, as well as a shift in demand toward crude from the Atlantic Basin.

In the short term, AERC expects Brent crude prices to remain within the range of $98.7–104/bbl, provided there are no additional external shocks. The average Brent crude price is forecast at around $100.2/bbl.
