Biofuels remain a key demand driver in agriculture amid the risk of structural oversupply

Global agriculture is entering a phase of structural transformation, where productivity growth is outpacing the increase in food demand. This creates risks of excess supply of grains, oilseeds, and fiber crops, partially offset by demand from the biofuel sector. At the same time, slowing population growth and per capita consumption are increasing long-term pressure on agricultural incomes. In this environment, biofuels are increasingly seen as one of the few stabilizing forces in agricultural commodity demand, although their share in global liquid fuel consumption remains around 3.2%.

However, the ethanol market is under increasing pressure due to the expansion of electric vehicles, improving fuel efficiency, and stagnation in blending mandate policies. Under current market conditions, U.S. ethanol demand could decline by nearly 50% by 2050 to about 6.6 billion gallons. This would directly impact the corn sector, where a significant share of production is used for ethanol, potentially reshaping domestic grain demand structures.

The implications for farmland are substantial: around one-third of U.S. corn acreage dedicated to ethanol production could lose its current purpose. This would represent a large-scale withdrawal of land from production and could intensify structural grain surpluses, adding long-term pressure on prices.

At the same time, renewable diesel policy continues to support oilseed demand, particularly soybeans. U.S. crushing capacity has increased by roughly 20% since 2022, strengthening the role of soybean oil in value formation and shifting the balance between protein and oil components in soybean pricing. Further biodiesel expansion is expected to partially offset weakness in the ethanol segment.

Additional growth potential is emerging in sustainable aviation fuel (SAF) and marine fuels, which currently hold a small share of the global market but are seen as long-term demand drivers for agricultural feedstocks. These segments could become major new channels for biomass consumption amid transport sector decarbonization.

In an optimistic scenario driven by policy support, technological progress, and efficiency gains, global biofuel production could grow multiple times by 2050. This includes ethanol, biodiesel, and emerging aviation and marine fuels, significantly expanding agricultural feedstock markets.

The realization of this potential largely depends on agricultural technological advancement, including crop breeding, precision farming, and digitalization. However, adoption levels remain uneven, limiting productivity growth in certain regions and segments.

Thus, biofuels are gradually becoming a structural component of the global agricultural balance, simultaneously constraining oversupply and creating new demand centers. At the same time, reliance on specific segments—particularly ethanol—introduces risks of structural shifts in long-term grain demand.
