Industries often act illogically in cases like this. You see it with many types of goods ordered a long time in advance.
If there is a sudden shortage, the people who have ordered their raw materials a long time in advance (who have effectively purchased a future for that commodity) think they made a good move and see it as a business advantage that they can continue production while their competitors who failed to plan cannot.
However, they often fail to see that it is an even better business move to still shut down production and sell those raw materials onwards to someone else who will pay handsomely for them.
Basically, the futures market should never determine if a factory is operating or not. If it does, then someone has made an irrational decision.
