Entering December, the domestic corn market prices have slightly rebounded, supported by rising costs, and the domestic corn starch market prices have slightly increased. Starting from mid December, the overall price increase of domestic corn market stabilized and then fluctuated slightly, with raw material costs stabilizing. However, due to the sufficient inventory of corn starch and the expectation of less urgent downstream demand, domestic corn starch prices fell slightly.

The corn starch product analyst from SunSirs believes that the upstream raw material costs have stabilized weakly, and downstream demand is not expected to be urgent. It is expected that the domestic corn starch market prices will continue to operate under pressure in the short term.
