Crude Oil Rally Lifts Chicago Soybean and Corn Futures as Wheat Retreats

Biofuel link lifts oilseeds and corn

Chicago soybean and corn futures began the week with modest gains as a rapid rise in crude oil prices strengthened the market’s expectations for the ethanol and biodiesel sectors. Terre-net reported that the move in energy markets followed a further escalation of conflict in the Middle East during the weekend, including critical strikes on an oil pipeline in Saudi Arabia and the seizure of the Bab el-Mandeb Strait by Yemen’s Houthi rebels.

The connection with crude oil matters because corn is a major feedstock for US ethanol production, while soybean oil is used to manufacture biodiesel and other renewable fuels. Higher petroleum prices can improve the relative economics of these alternatives, although the resulting support for agricultural futures also depends on processing margins, government policy and actual fuel demand.

Soybean inspections exceed expectations

Physical trade data added support to soybeans. Weekly inspections at US ports reached 673,000 tonnes, exceeding market expectations, according to Terre-net. Corn inspections totaled 1.53 million tonnes and were in line with the market consensus, while wheat inspections of 457,000 tonnes also matched expectations.

The figures indicate a stronger-than-anticipated weekly flow of US soybeans into export channels. For traders and processors, however, one week of inspections does not establish a lasting demand trend. Subsequent shipments, destination demand and competition from other producing countries will determine whether the improvement translates into sustained support for prices.

Higher crop forecasts weigh on wheat

Wheat moved in the opposite direction. The market remained under pressure from the latest monthly global supply-and-demand report by the US Department of Agriculture. Terre-net said the USDA substantially raised its crop estimates for Australia and Canada, as well as Argentina. The larger harvest outlook suggests that those suppliers could offset reduced Black Sea export potential caused by the war between Russia and Ukraine.

The USDA left its forecast for US exports in 2026/27 unchanged. Terre-net linked that outlook to a particularly weak US harvest and American prices that remain high compared with competing origins. The combination leaves US wheat exposed to pressure from suppliers with larger crops and more competitive offers, even as disruption around the Black Sea limits part of the global export pool.

At the Chicago close, December 2026 soft red winter wheat fell 3.25 cents per bushel to $7.22 per bushel. December 2026 corn gained 3.0 cents to $5.33 per bushel, while November 2026 soybeans rose 7.75 cents to $13.04 per bushel. The session showed two distinct drivers: energy-market strength and soybean export activity supported corn and oilseeds, while expectations of greater wheat availability outside the United States kept pressure on wheat futures.
