One of the biggest mistakes commodity traders make is reacting emotionally to isolated weather extremes rather than understanding the larger atmospheric picture.
During the summer of 2026, drought affected portions of the western Corn Belt, while excessive rainfall and flooding created serious concerns across the eastern Midwest and Ohio Valley. These developments encouraged speculation that U.S. soybean production might suffer substantial losses.
By examining historical analogs, ocean temperatures, atmospheric circulation patterns, and teleconnections such as ENSO, the PDO, PNA, and other climate indices, we were able to look beyond the headlines.
While certain growing regions experienced legitimate weather problems, other important soybean-producing areas benefited from adequate moisture and generally favorable growing conditions.
Our conclusion: Regional weather adversity did not automatically translate into a small national soybean crop.
Rather than getting caught up in bullish weather speculation, we continued emphasizing the potential for a very large U.S. soybean harvest.
The USDA's October forecast of 4.56 billion bushels and a record 53.1 bushels per acre reinforced that assessment.
Over the last month, we also warned that two developments could pressure soybean futures:
Soybean futures subsequently suffered a substantial decline, with prices falling more than $1 per bushel from their early-autumn highs. For traders who followed our bearish recommendations, this created an opportunity to capture meaningful profits.
Successful commodity trading is not simply about predicting the weather correctly. It is also about recognizing when bearish fundamentals have become widely anticipated and reflected in prices.
Our accompanying ClimatePredict Pro graphic (featured at the top of this page) illustrates five reasons we believe covering soybean shorts makes sense now.
Finally, El Niño introduces additional uncertainty. Our teleconnection analysis suggests that South American rainfall patterns could become more volatile as the growing season progresses. However, El Niño alone does not guarantee drought or a bullish soybean market.
Our research helped us avoid becoming overly bullish during the summer's weather scares. The combination of a massive U.S. crop, harvest pressure, and initially favorable South American growing conditions subsequently supported our bearish outlook.
Now, after the substantial autumn sell-off, we believe the prudent strategy is to take profits on soybean shorts rather than become excessively bearish near the end of harvest.
A post-harvest recovery is increasingly possible as Chinese buying strengthens, seasonal selling diminishes, and South American weather becomes more important.
This does not necessarily mean a major new soybean bull market is beginning.
That is the advantage of combining long-range weather forecasting, historical teleconnections, fundamental analysis, and disciplined trading.
