U.S. Corn Futures Reach Highest Level Since January

U.S. corn futures surged on Friday, hitting their highest level since late January. Despite this, the gains were later pared. Soybeans reached a one-month peak as floods disrupted harvests in Brazil, a leading exporter, while disease impacted Argentina’s corn crop. Analysts noted these factors contributed to the rise in prices.

Wheat Futures Hit One-Week High

Wheat futures also experienced a rise, reaching a one-week high. This increase was driven by renewed concerns over dry weather in Russia, the world’s largest wheat supplier. The adverse weather conditions have raised fears about the impact on crop yields.

Corn and Soybean Prices Supported by Brazilian Floods

Corn and soybean prices found support due to flooding in Brazil’s Rio Grande do Sul, where the harvest is in its final stages. Rio Grande do Sul is Brazil’s second-largest producer of soybeans and the sixth-largest producer of corn. The flooding has severely disrupted the harvest, leading to higher prices.

Impact of Corn Stunt Disease in Argentina

In Argentina, the spread of corn stunt disease, which is transmitted by leaf-cutter insects, combined with adverse weather conditions, prompted the Buenos Aires grains exchange to reduce its estimate for Argentina’s 2023/24 corn harvest by 3 million metric tons, bringing it down to 46.5 million tons. This significant reduction has added upward pressure on corn prices.

Influence of Labor Strikes in Argentina

Labor issues have further supported prices. Susan Stroud, an analyst at, highlighted that it is the season for strikes in Argentina, referring to labor disruptions affecting the country’s grain ports. These strikes have contributed to the overall uncertainty and volatility in the grain markets.

Russian Wheat Forecast Adjustments

In the wheat market, Russia’s IKAR agricultural consultancy reduced its forecast for the country’s crop to 91 million metric tons, down from 93 million tons. Additionally, the forecast for wheat exports was cut to 50.5 million metric tons from 52 million tons. These adjustments reflect the ongoing challenges faced by Russian agriculture due to adverse weather conditions.

Weather Forecasts and Market Reactions

Weather forecasts predicting virtually no rain in Russia over the next two weeks have further fueled concerns. This has led to increased buying activity from end-users and commercial buyers. Mike Zuzolo, president of Global Commodity Analytics, noted that the combination of Russian weather issues and a weaker U.S. dollar has created a confluence of buying interest.

Managed Money Funds and Wheat Futures

At the beginning of 2024, managed money funds held a net short position in CBOT wheat futures due to a strong dollar and slow U.S. demand. However, the current weather conditions and market dynamics have shifted the sentiment, leading to increased buying activity and rising prices.

Analysis of CBOT Corn Futures

On Friday, the Chicago Board of Trade (CBOT) July corn contract settled up 1/2 cent at $4.60-1/4 per bushel, after reaching a peak of $4.68, the highest level since January 26. Brokers reported that corn sales by U.S. farmers increased starting on Thursday as the contract price broached $4.60, indicating a strong market response to the price movement.

Soybean and Wheat Futures Performance

The CBOT July soybeans contract settled up 16 cents on Friday, closing at $12.15 per bushel. Meanwhile, the July wheat contract rose 18-1/4 cents to finish at $6.22-1/2 per bushel. These price movements reflect the broader market trends influenced by global weather conditions and supply concerns.

Global Weather and Crop Conditions

The global weather conditions have played a crucial role in shaping the current market dynamics. In South America, flooding in Brazil and disease in Argentina have disrupted crop production, leading to reduced supply and higher prices. In Russia, dry weather has raised concerns about wheat yields, further tightening global supplies.

Market Implications and Future Outlook

The ongoing weather challenges and labor issues in key producing regions highlight the vulnerability of global agricultural markets. As the situation evolves, market participants will closely monitor weather forecasts, crop conditions, and labor developments to gauge their impact on supply and prices. The current market environment underscores the importance of resilience and adaptability in the face of unpredictable factors.

Strategic Considerations for Traders and Investors

For traders and investors, the current market conditions present both opportunities and risks. Understanding the interplay between weather conditions, crop production, and market sentiment is crucial for making informed decisions. Diversification and risk management strategies will be essential in navigating the volatile agricultural markets.


The recent surge in U.S. corn futures, alongside rising soybean and wheat prices, reflects the significant impact of global weather and crop conditions on agricultural markets. The disruptions in Brazil and Argentina, coupled with dry weather in Russia, have created a complex market environment. As these factors continue to unfold, market participants must remain vigilant and responsive to changes, leveraging insights and strategies to manage risks and capitalize on opportunities. The coming weeks will be critical in determining the trajectory of prices and the overall stability of the agricultural markets.
