The Organization of the Petroleum Exporting Countries (OPEC) has slightly lowered its forecast for global oil demand growth in 2026 while raising its outlook for 2027, indicating that it continues to expect oil consumption to expand despite ongoing economic and geopolitical uncertainties.

According to Anadolu Agency, OPEC now expects global oil demand to increase by 780,000 barrels per day (bpd) in 2026 compared with 2025, bringing average worldwide consumption to 105.94 million bpd.

Although the 2026 forecast has been revised down marginally from OPEC's previous estimate, the organization still expects demand to reach a new record level, suggesting that oil will remain a key component of the global energy mix.

What is OPEC?

OPEC is an intergovernmental organization made up of major oil-producing countries that coordinate petroleum policies among member states. Together with allies including Russia under the OPEC+ framework, the group plays a significant role in global crude oil supply.

Beyond setting production targets for member countries, OPEC publishes regular assessments of the global oil market, including forecasts for supply, demand, economic growth and inventories. These reports are widely monitored by governments, financial institutions, traders and energy companies because they help shape expectations about future market conditions.

Why was the 2026 forecast lowered?

OPEC's latest report only slightly reduced its estimate for demand growth in 2026, meaning the organization still expects oil consumption to continue increasing rather than weakening.

A downward revision does not necessarily indicate falling demand. Instead, it means OPEC expects consumption to grow at a somewhat slower pace than it projected previously.

Even after the adjustment, projected global demand of 105.94 million bpd would remain above 2025 levels, reflecting continued expansion in worldwide energy consumption.

Emerging economies remain the main growth engine

According to OPEC's projections, nearly all of the expected increase in oil demand will come from non-OECD countries.

Demand across non-OECD economies-which include large emerging markets in Asia, the Middle East, Africa and Latin America-is forecast to rise by 740,000 bpd to average 59.95 million bpd in 2026.

These economies continue to experience rising energy needs driven by factors such as population growth, industrial development, expanding transportation networks and increasing economic activity.

By contrast, oil demand in OECD countries is expected to grow by just 40,000 bpd, reaching an average of 45.99 million bpd.

The relatively modest increase reflects the more mature nature of advanced economies, where improvements in energy efficiency, greater adoption of electric vehicles and the transition toward lower-carbon energy sources have contributed to slower growth in oil consumption.

Why is the OECD/non-OECD split important?

The distinction between OECD and non-OECD countries has become increasingly important in the global oil market.

For decades, advanced economies accounted for most global oil consumption. However, demand growth has increasingly shifted toward developing economies, where expanding populations, urbanization and industrialization continue to boost fuel use.

As a result, producers closely monitor economic trends in emerging markets because they are expected to account for most future increases in global oil demand.

OPEC becomes more optimistic about 2027

While trimming its 2026 outlook, OPEC raised its forecast for 2027.

The organization expects global oil demand to increase by a further 1.94 million bpd in 2027, bringing average consumption to approximately 107.88 million bpd.

The stronger outlook suggests OPEC expects the global economy to continue supporting higher energy consumption over the medium term.

If realized, the forecast would extend the trend of record global oil demand despite the growing use of renewable energy and efforts by many countries to reduce greenhouse gas emissions.

Why these forecasts matter

OPEC's demand forecasts are among the most closely watched indicators in global energy markets.

Oil producers use them when planning production and investment decisions, while governments and central banks monitor them as part of broader assessments of economic activity and inflation.

Investors also pay close attention because expectations about future oil demand can influence crude prices, energy company earnings and financial market sentiment.

Demand forecasts are especially important for OPEC+, whose production decisions often depend on the expected balance between global supply and consumption.

The bigger picture

Although OPEC slightly reduced its estimate for demand growth in 2026, its latest outlook continues to point to a resilient global oil market.

The forecasts suggest that oil demand will keep rising over the next two years, driven primarily by non-OECD economies, while advanced economies are expected to see comparatively limited growth in consumption.

Overall, OPEC's latest projections reinforce its long-held view that global oil demand will continue expanding in the medium term, even as countries accelerate the transition toward cleaner sources of energy.
