When local soybean harvest size exceeds storage capacity, what typically happens to the basis?

• A. Basis narrows
• B. Basis widens
• C. Basis remains constant
• D. Basis becomes inverted

Answer: (B)

When local soybean harvest size exceeds storage capacity, the basis typically widens. The basis is the difference between the local cash price and the futures price (basis = cash minus futures). With a harvest glut, the immediate supply in the cash market climbs, pushing local cash prices down. The nearby futures price, which reflects expectations for future delivery and broader market conditions, doesn’t fall as quickly in the short term. This increases the gap between cash and futures, making the basis more negative and larger in magnitude—that’s a widening basis. For example, if nearby futures are $10.00 and local cash falls from $9.50 to $9.00 due to the surplus, the basis shifts from -$0.50 to -$1.00, a wider basis. The other options don’t fit because a constant basis ignores the new local supply impact, an inverted basis would require cash prices to exceed futures prices, which is unlikely in a harvest-overflow scenario, and a narrowing basis would imply the cash price falls less than or tracks the futures, which isn’t typical when storage is constrained and supply is abundant.
