Hedging your crops on Wall Street doesn't protect you from the greedy grain elevator down the road. Farmers use Chicago Mercantile Exchange futures to lock in wheat prices, but they face 'basis risk'—the wildly unpredictable price gap between the global exchange rate and their local cash market. If local transport costs spike or silos fill up, the hometown price plummets regardless of the Chicago ticker, leaving the farmer to eat the devastating financial difference.
