A rally in Chinese corn prices is spurring the government to action, which includes taking an unusual step of bolstering supply at a time when sales from farmers are poised to expand. The government announced a plan last week to resume state corn sales, which will be the first time in years it’s doing so during a seasonal peak period for farmers’ sales. On Monday, China’s top corn region of Heilongjiang followed with an offer to sell almost 1 million tons to designated buyers. These are on top of the 1.3 million tons already sold to refineries and feed mills in Jilin and Heilongjiang in the previous two weeks.

While volumes from the government’s latest sale are less than the 4 million tons-a-week seen between May and September, the move is a signal that China doesn’t want to see prices rise too much, said Meng Jinhui, a senior analyst at Shengda Futures.

Chinese corn gets increasingly more expensive than U.S. supply
