Historically Strong El Niño Threatens Global Corn, Palm Oil Supply, CICC Says

A developing "super" El Niño event, potentially the strongest on record, is poised to disrupt global agricultural markets and drive commodity prices higher, according to a new research report from China International Capital Corporation (CICC). The investment bank warns that historical patterns point to significant production cuts for corn and palm oil, exacerbating an already tight supply environment.

A Confluence of Market Pressures

Citing forecasts from the U.S. National Oceanic and Atmospheric Administration (NOAA), CICC notes that the impending El Niño could set a record for sea surface temperature anomalies in the Pacific. This weather phenomenon typically peaks between November and January, coinciding with the critical growing season for key crops in the Southern Hemisphere.

The report argues that this extreme weather event arrives at a vulnerable time for global markets. Agricultural supply-demand fundamentals are already shifting from a loose to a tight balance. This is compounded by geopolitical factors, including high oil prices driven by shipping constraints in the Strait of Hormuz and ongoing disruptions to Black Sea grain exports.

CICC's analysts believe this combination of tight supply, geopolitical tension, and extreme weather will catalyze a surge in prices. Under a neutral scenario, the bank forecasts that CBOT corn prices could rise by 20% and soybean prices by 10% over the next three to six months.

Historical Patterns Signal Production Risks

CICC's forecast is grounded in an analysis of strong and super El Niño events since 1960, which reveals distinct impacts on different crops.

• Corn: The three previous super El Niño events all led to global production cuts. These reductions were primarily driven by Brazil, which experienced acreage declines of 17-18% in two of those instances.
• Palm Oil: Production fell during all three past super El Niño events. The crop's high concentration in Southeast Asia makes it particularly vulnerable to the regional drought conditions typically caused by the weather pattern.
• Soybeans: The impact is more nuanced, with two of the last three super El Niños resulting in a net production *increase*. CICC explains this is due to a balancing effect in Brazil, where drought in the north is often offset by increased rainfall in the south.

Price Outlook and Market Dynamics

The investment bank's price targets are based on a model where every one-percentage-point drop in the global stock-to-use ratio for corn and soybeans corresponds to price increases of approximately 20% and 9%, respectively. For corn, U.S. drought conditions have already provided price support, with potential flooding in South America now determining the upper limit of a rally.

For soybeans, expectations of a downward revision in global output are lifting prices, while high oil prices bolster demand for biodiesel, a key soy product. CICC added that it expects limited impact on China’s domestic supply of staple grains like wheat and rice, which it assesses as sufficient.
