Market fundamentals
In this trading session, soybean and corn prices were pressured by the sharp drop in oil prices on the international market, a movement that reduces the economic attractiveness of biofuel production based on oilseeds and cereals. The market also reacted to statements from Qatari and US authorities, which raised expectations of a diplomatic solution to the conflict involving Iran. The prospect of normalization of oil flow through the Strait of Hormuz contributed to the devaluation of the energy commodity. In the US, the Department of Agriculture (USDA) It was reported that 63% of soybean crops remain classified as good to excellent, a stable percentage compared to the previous week. For corn, however, the index fell from 63% to 61%, remaining below the 73% recorded in the same period of 2025. Soybean losses were partially limited by continued Chinese demand. USDA The agency announced a one-off sale of 132,000 tons of soybeans to China, with delivery scheduled for the 2026/27 marketing year. This was the second consecutive day of announced purchases by the agency, following the sale of 488,000 tons to the Asian country and 136,150 tons to an undisclosed destination on Monday. In the wheat market, in addition to the negative influence of soybeans and corn, investors continued to monitor the conflict between Russia and Ukraine. Despite concerns about export flows through the Black Sea, the expectation of ample global supply, especially in the region, continued to put downward pressure on prices. USDA It also reported that the winter wheat harvest has progressed to 86% of the cultivated area in the United States, after a weekly increase of 5 percentage points. The spring wheat harvest has reached 5% of the area, below the five-year average (8%). Crops classified as good and excellent represent 55% of the total, above the 48% observed in the same period last year.
