Corn on the Rise: How Weather and War Are Driving Prices Higher
Introduction: A Perfect Storm for the Grain Market
Monday became the day when two completely different factors converged, creating powerful momentum for higher corn prices. Weather forecasts predicting heat and drought across the US Corn Belt, combined with geopolitical tensions in the Middle East that pushed oil prices higher, sent corn futures to their highest levels in more than a month.
The September contract closed 1.5 cents higher at $4.41 per bushel. The new-crop December contract posted an even more impressive gain, rising 2.25 cents to $4.63¼ and reaching an intraday high of $4.69½—the highest level since June 2.
What is driving this rally? Why do weather conditions in American fields and conflict in the Persian Gulf affect the price of corn? And how long could this trend continue? Let us examine this agricultural mystery, in which meteorology, geopolitics, and the biofuel economy are closely intertwined.
The Weather Factor: Heat and Drought Threaten the Harvest
A Critical Period for Corn
July is the month that determines the fate of the US corn harvest. Pollination takes place during this period—a crucial stage that directly affects kernel development. Heat and drought at this time can cause irreversible damage to the future crop.
Forecasters expect hot and predominantly dry weather across the western part of the US Corn Belt this week, with similar conditions potentially continuing into the following week. This is an alarming signal for both farmers and traders.
The Corn Belt is the heart of American agriculture and the region where most of the country’s corn is produced. Iowa, Illinois, Nebraska, and Indiana are among the states at risk. If weather conditions fail to improve, yields could decline significantly.
