When the size of the soybean harvest exceeds locally available storage, what happens to the basis?

When the size of the soybean harvest exceeds locally available storage, what happens to the basis?

• A. Narrows
• B. Widens
• C. Stays the same
• D. Becomes negative

Answer: (B)

The key idea is how basis is defined and how local supply interacts with futures pricing. Basis is the local cash price for soybeans minus the nearby futures price. When the harvest is larger than what local storage can handle, a glut develops in the cash market: sellers flood the market and cash prices fall. The futures price, which reflects expectations for delivery and broader market conditions, doesn’t fall by the same amount because it’s influenced by supply across regions and longer-term storage considerations. So the difference between cash and futures grows larger in magnitude, meaning the basis widens (the cash price drops relative to the futures price). For a quick feel: if cash is 13.50 and the nearby future is 13.95, the basis is -0.45. If the harvest glut pushes cash down further to 13.00 while futures stays near 13.90, the basis becomes -0.90, a wider gap. The idea isn’t that the basis becomes a fixed negative value; it’s that the gap between cash and futures expands in response to the local oversupply.
