How do market prices and cycles affect agricultural commodities?

• A. Lower price volatility.
• B. Higher price volatility, significant price co-movement, and a higher real price level for all three commodity groups.
• C. Prices are completely predictable.
• D. Only supply affects price levels.

Answer: (B)

Market prices for agricultural commodities respond to cycles of supply and demand and to shocks that change expected harvests. When weather events, pests, or disease hit a major producing region, supplies shift and prices jump; when yields come in higher than expected or stocks are ample, prices ease. Because many commodities share the same global drivers—growth in demand, currency movements, energy costs, and policy changes—these shocks often push multiple markets in the same direction, creating significant price co-movement. Over time, persistent tightness or inflationary pressures can lift the real price level across the major commodity groups. So you see more price volatility, prices moving together across different commodities, and a higher real price level overall.
