Global Maize Market Weekly Summary

• The global maize market remains under pressure as strong crop prospects in major producing regions are offsetting supportive demand factors. In the United States, corn futures continued to weaken, reflecting bearish market sentiment driven by rapid planting progress, favorable growing conditions, and weaker energy prices that have reduced ethanol production margins. With 93% of the crop planted by late May, slightly ahead of the historical average, expectations for a large harvest have reinforced downward pressure on prices. Although export commitments remain strong and are running significantly above last year's pace, fund liquidation and elevated domestic ethanol inventories continue to weigh on the market. Technical indicators suggest a cautious outlook, with prices trading near key support levels.
• In Brazil, the corn market is being shaped by tightening supply expectations. Production estimates for the safrinha crop have been revised lower due to drought-related losses in important growing regions, reducing the country's projected exportable surplus. At the same time, strong domestic demand from the ethanol sector, supported by the E30 fuel mandate, continues to absorb significant volumes of corn. As a result, Brazil's stocks-to-use ratio has tightened, raising concerns about future export availability and potentially shifting some international demand toward alternative suppliers.
• Argentina has emerged as a major source of bullish supply-side news, with record maize production estimated at approximately 203.5 million metric tons for the 2025/26 season. Expanded acreage and favorable yields have strengthened the country's export potential, positioning Argentina to capture additional market share, particularly if Brazilian exports become constrained. However, domestic economic conditions, including inflationary pressures and export policies, may influence the pace at which supplies reach international markets.
• Meanwhile, Ukraine continues to face logistical challenges despite maintaining substantial export volumes. Corn exports have declined slightly from the previous year, while a large backlog of grain awaiting shipment highlights ongoing transportation and infrastructure constraints that could affect global supply flows. In Asia, Thailand's decision to import one million tons of U.S. maize reflects continued structural demand and provides additional support for U.S. exporters in an increasingly competitive global market.
