Corn Surges as Weather Risks Mount Across Key Grain Markets
Corn has emerged as the strongest grain market, surpassing wheat in terms of price movement. Chicago corn futures rose by four percent over the week and are now five percent higher than they were a month ago.
The US Department of Agriculture's crop ratings fell more sharply than expected, with only 57% of corn rated good-to-excellent, down three percentage points from the previous week. The Pro Farmer crop tour estimated US corn yields at 10.9 tonnes per hectare, below the USDA's most recent estimate of 11.3 t/ha.
The gap between these two estimates is significant enough to make traders question whether current US production forecasts are too optimistic. This has contributed to the sharp increase in corn prices.
Europe's maize outlook has also deteriorated, with the EU's crop monitoring service cutting average maize yield to 6.61 tonnes per hectare, down from 6.93 in July and now seven percent below the five-year average. Other summer crops, such as soybeans and sunflowers, have also suffered.
India is facing its weakest monsoon since 2009, with rainfall tracking around 13% below average. This could impact crop yields and lead to food shortages.
