Core tip: According to foreign media on July 27, as of the week ending July 25, 2025, global corn prices mostly declined, mainly due to rainfall in the central United States alleviating the growth pressure caused by high temperatures, and the upward revision of Brazil's corn production estimate boosting the global corn supply outlook, while international crude oil futures fell. However, improved U.S. corn export sales, along with market expectations of a trade agreement between the U.S., China, and the EU, limited the downward potential of the corn market.
