Why is the price of corn reduced?

Hello, due to the financial crisis, the international economy is very depressed. Although China is not the most seriously affected country, China's economy has also been greatly impacted. Now, let alone how much the international oil price has dropped, the domestic refined oil price has also begun to drop, and of course the price of ethanol gasoline will also drop. Why doesn't the corn used to produce ethanol gasoline drop? However, the corn used to produce ethanol gasoline accounts for only a small part of the total corn production. Now that the price of meat and eggs has dropped, the price of corn, the most important raw material of feed, will definitely drop. Moreover, the financial crisis has affected the corn price in the international market, and China has joined the WTO. Of course, our corn price will fluctuate with the change of international price.
