Highlights at a glance

For the week ending May 15, 2026, global corn prices declined as disappointing results from the China-U.S. summit and sluggish export sales weighed on sentiment. The CBOT July corn contract dropped 3.3% to $4.5575/bushel, despite support from E15 legislation and drought concerns in Brazil. In China, corn prices edged down 0.40% amid tight supply but weak demand, with processors prioritizing inventory drawdowns and increasing use of wheat and imports. DCE corn futures fell 0.42%, reflecting bearish sentiment ahead of new wheat harvest. While short-term pressure persists, cost-driven support and limited substitution may underpin prices later in the season.

🌍 International Markets

For the week ending May 15, 2026, global corn prices declined. The downturn was primarily driven by disappointing outcomes from the China-U.S. summit, sluggish U.S. corn export sales, and the smooth progress of spring planting in the Midwest. However, the market found some support from the U.S. House of Representatives passing the E15 year-round sales proposal, as well as looming drought threats in Brazil's second-crop corn regions.

As of last Friday (May 15), the Chicago Board of Trade (CBOT) July corn contract closed at $4.5575 per bushel, marking a weekly drop of 3.3%. Meanwhile, the Gulf Coast June corn shipment price was quoted at $5.3975 per bushel, down 2.8% for the week.

🏠 Domestic Market (China)

The market has largely digested the rumors surrounding domestic directional rice auctions. Due to the high cost of stockpiling, some traders have reduced their willingness to sell, leading to a tighter supply of circulating grain. While grain-consuming enterprises maintain adequate inventory, demand for corn continues to be diverted by imported grains. Weak downstream demand has kept prices in a state of weak fluctuation, with a week-on-week decline of 0.40%.

Currently, processing enterprises are primarily focused on depleting existing inventory. The sluggish downstream market has restricted upstream sales. Restocking intentions among deep-processing enterprises are limited to meeting rigid demand, while feed enterprises remain highly cautious. Some companies are increasingly using wheat and imported grains as substitutes in production, further suppressing spot prices due to weak demand.

📉 Futures Market

Domestic corn futures continued their downward trend this week. Although the negative impact of the directional rice policy has been gradually absorbed, bearish sentiment still dominates the market. With the harvest and market launch of new wheat approaching and demand remaining sluggish, the declining trend in corn spot prices has further dampened sentiment in the futures market.

As of last Friday (May 15), the DCE C2607 corn contract opened at 2,366 yuan/ton and closed at 2,355 yuan/ton, down 16 yuan/ton. The settlement price was 2,363 yuan/ton, with a weekly high of 2,371 yuan/ton and a low of 2,354 yuan/ton, marking a weekly decline of 0.42%.

🔮 Market Outlook & Analysis

The USDA's May Supply and Demand Report forecasts that both the planted area and yield per acre for the new U.S. corn crop will be lower than the previous year, presenting a neutral-to-bullish influence on the market. However, the failure to secure agricultural procurement contracts during the high-level China-U.S. meeting has introduced uncertainty into corn export prospects, making a short-term breakout rally in CBOT corn unlikely.

Domestically, as the harvest date for new wheat approaches, traders may temporarily clear warehouse space, potentially leading to a short-term increase in supply. Against the backdrop of continuous losses in both breeding and deep-processing profits, downstream consumption has not shown significant improvement, keeping corn prices under pressure.

Nevertheless, several factors suggest strong underlying support for prices:
