Global oil refining market seen reaching $3.75 trillion by 2030

Allied Market Research says the oil refining market was worth $1.345 trillion in 2020 and could nearly triple to $3.75 trillion by 2030. The forecast points to stronger fuel demand, refinery modernization and petrochemical growth, even as electric vehicles and cleaner energy create long-term pressure on conventional refining.

Why it matters: - The oil refining market sits at the center of transportation, petrochemicals and industrial energy supply. - Allied Market Research projects the market will rise from $1,345.0 billion in 2020 to $3,751.5 billion by 2030. - The forecast implies a 5.3% compound annual growth rate from 2021 to 2030. - Rising refinery investment could affect fuel availability, industrial feedstock supply and energy security across major economies.

What happened: - Allied Market Research published a market outlook on the oil refining industry on July 1, 2026. - The report says global demand is being driven by higher energy use, more transportation activity and refinery modernization. - The report includes a downloadable brochure and a purchase option for the full report.

The details: - Oil refining converts crude oil into gasoline, diesel, kerosene, liquefied petroleum gas, aviation fuel, lubricants and petrochemical feedstocks. - Refineries use atmospheric and vacuum distillation, then secondary processes such as catalytic cracking, hydrocracking, reforming and desulfurization. - Modern refineries are adding automation, digital monitoring, emission controls and process optimization tools to improve efficiency and meet environmental rules. - The market is being supported by industrialization, urbanization, petrochemical expansion and higher demand for transportation fuels. - Governments and energy companies are investing in refinery upgrades, capacity expansion and digital transformation. - The report says renewable energy, electric vehicles and cleaner transportation technologies are a long-term challenge for conventional refining. - Deep conversion refineries held the largest share in 2020 because they can produce higher-value products and meet tighter fuel-quality standards. - Light distillates led product categories, while gasoline was the largest fuel segment. - Transportation was the leading application segment.

Between the lines: - The forecast suggests the industry is shifting from simple fuel production toward higher-efficiency, more flexible and more integrated refining systems. - Refinery modernization appears to be as important as new capacity, since cleaner output and lower emissions are becoming competitive requirements. - Asia-Pacific's lead in the market reflects both demand growth and large-scale industrial buildout in China, India and Southeast Asia. - North America benefits from advanced infrastructure and strong crude output, while Europe is emphasizing cleaner fuels and modernization. - The Middle East is investing in integrated refining and petrochemical complexes to capture more value from crude exports.

What's next: - The report expects Asia-Pacific to keep its lead through 2030. - Refiners are likely to keep investing in automation, predictive maintenance, artificial intelligence and advanced catalysts. - Capacity expansion and petrochemical integration are expected to remain key strategies in emerging economies. - Refineries will also need to balance growth plans with emissions rules and changing transport demand. - More information is available in Allied Market Research's market page.

The bottom line: - The oil refining market is still set for strong growth, but the winners will be operators that can modernize fast, improve margins and adapt to a slower transition in fuel demand.
