OPEC now expects global oil demand to grow by just 0.2 million b/d in 2026, year-on-year — a figure that arrives, notably, after a slight downward revision from last month's assessment.

The number is small. It is also the second cut in as many months of reporting, and that pattern matters more than any single digit. A forecast can move once on noise. When it drifts lower twice, desks start asking what the group's analysts are seeing in the underlying data.

What does the new forecast say?

The headline is the 0.2 mb/d growth figure for 2026, but the split underneath it does the real work:

• OECD demand: forecast to ease by about 0.2 mb/d, year-on-year
• Non-OECD demand: forecast to grow by about 0.4 mb/d, year-on-year
• Global total: growth of 0.2 mb/d, after a slight downward revision from last month's assessment

Read the arithmetic and the shape of the market comes into focus. The non-OECD world is still adding demand — the 0.4 mb/d gain carries the entire forecast — but it is doing so at a pace that only just offsets the contraction in OECD consumption. Strip out the emerging-market growth and the developed economies are in outright decline on OPEC's own numbers.

That is a demand picture built on a narrow base. One softer quarter in the non-OECD segment and the global growth line thins toward flat.

Who is saying this, and why the attribution matters

The forecast comes from OPEC itself, relayed in its latest monthly assessment, as reported by CGTN. It is not an independent estimate from the IEA or a sell-side desk, and the distinction counts. Producer-group forecasts carry their own perspective, and any commentary on what the number means for prices is analysis to be attributed, not settled fact.

What can be stated plainly: OPEC's own analysts looked at 2026 and trimmed their view from the previous month. The group has put a specific, modest figure on demand growth, and it has split the forecast into a shrinking OECD and an expanding non-OECD.

Why a 0.2 mb/d forecast lands hard

Growth of 0.2 mb/d is thin cover for a 100-million-plus b/d market. For refiners, it frames margin expectations two years out — flat-to-falling OECD runs argue for continued capacity rationalization in Europe and parts of Asia, while the 0.4 mb/d non-OECD gain keeps product demand growth concentrated in emerging markets.

For upstream planners, the signal is similar. A demand outlook this modest gives operators little incentive to sanction supply that won't be needed before the end of the decade, and it keeps the pressure on OPEC's own production decisions, since the group's market management assumes a demand baseline it keeps revising down.

None of this is a verdict on prices. It is one forecaster's monthly update. But the direction of the revision — down, again — is the part worth watching.

The takeaway in plain words: OPEC sees 2026 demand growing barely at all, with emerging markets doing all the work and the developed world shrinking.

Watch item: the next OPEC monthly report, and whether the 2026 growth figure holds at 0.2 mb/d or takes a third consecutive trim.
