The Market Monitor AMIS No. 104 for December 2022 highlights the current state of the global grain and oilseed markets. With the northern hemisphere harvest largely completed, attention is now shifting to the southern hemisphere, where the third consecutive year of La Nina has led to drought conditions in Argentina, reducing wheat production prospects. In contrast, Australia is experiencing above-average wheat yields due to abnormal wet conditions, but concerns remain over the quality of the crop. Maize and soybean planting progress in South America is on track, but it is too early to tell whether yields will return to normal levels after last year's drought-reduced production. The Market Monitor is a product of the Agricultural Market Information System (AMIS), which covers international markets for wheat, maize, rice, and soybeans, providing a synopsis of major market developments and the policy and other market drivers behind them. The analysis is a collective assessment of the market situation and outlook by the ten international organizations and entities that form the AMIS Secretariat.
