Core Insight: According to foreign media on December 7, as of the week ending December 5, 2025, the global corn market, influenced by a mix of bullish and bearish factors, exhibited a typical range-bound oscillation pattern, lacking a clear direction. Chicago corn futures retreated from the multi-month high reached the previous week, primarily due to the promising outlook for a bumper South American corn harvest and reduced concerns over tensions in the Black Sea, which offset the support from robust U.S. corn export sales and a strengthening international crude oil market. Market focus has shifted to the U.S. Department of Agriculture's supply and demand report to be released next week, with expectations for new directional guidance.
