OPEC Cuts 2026 Oil Demand Forecast for Third Consecutive Time, Raises 2027 Outlook

OPEC cut its 2026 global oil-demand growth forecast for a third consecutive time to 780,000 b/d, while raising its 2027 outlook to 1.94 million b/d — a split signal of near-term caution and medium-term optimism that leaves the market without a consensus price anchor.

01

Why has the 2026 demand forecast been cut three times running?

OPEC lowered its 2026 global demand-growth estimate from 970,000 b/d to 780,000 b/d — the third consecutive downward revision.
The core driver: after war broke out with Iran, the Strait of Hormuz — one of the world's most critical oil chokepoints, carrying roughly a fifth of seaborne crude — was effectively shut for months, trapping millions of barrels of Middle Eastern output.
This means → the world did not stop wanting oil; the oil simply could not get out. A physical supply disruption dragged down the statistical demand-growth number.
02

Why is the 2027 outlook being raised instead?

OPEC lifted its 2027 demand-growth forecast from 1.73 million b/d to 1.94 million b/d, an increase of 210,000 b/d.
The report's logic: if the interim Iran–U.S. peace deal holds and energy trade routes stabilize, global growth gets upside room from late 2026 onward.
In plain terms = OPEC is betting on a post-war rebound — once the strait truly reopens, pent-up demand and idled production flood into 2027.
03

How far apart are OPEC and the IEA — and why?

OPEC sees 2026 demand still growing (+780,000 b/d). The IEA forecasts a decline of 1 million b/d; the U.S. EIA projects an even steeper drop of 1.2 million b/d.
The widest gap between these forecasts exceeds 1.8 million b/d — roughly the entire output of a mid-sized producer.
This reflects a fundamental disagreement: OPEC views the war's impact on consumption as limited and temporary; the IEA sees demand as structurally compressed.
04

What has changed on the supply side?

June OPEC+ output averaged 36.28 million b/d, up roughly 3 million b/d from May, as Gulf members began restoring production halted during the Iran conflict.
The UAE formally exited OPEC and OPEC+ on May 1, yet its output is still included in the May and June figures.
This means → future monthly reports will strip out UAE volumes, so OPEC+'s headline production will appear to shrink overnight — even though actual global supply has not changed. Watch for this statistical-base shift when reading the data.
05

What does this mean for the market?

Three consecutive downgrades to 2026, combined with a 1.8-million-b/d forecasting gap with the IEA, mean the market has no consensus anchor for the oil-price midpoint in the near term.
Whether the bullish 2027 outlook materializes hinges on one prerequisite: lasting, stable reopening of Strait of Hormuz shipping — yet a fresh round of military strikes has already revived fears of another disruption.
In plain terms = the short-term direction for oil prices is unclear, because the most authoritative forecasters cannot even agree on whether demand is rising or falling; the medium-term bet rests entirely on whether peace holds.
