Commodities' Wild Swings May Be More Predictable Than Thought

Research from the University of Nebraska-Lincoln challenges traditional views on commodity price volatility. A study led by Fabio Mattos found that up to 80% of market fluctuations may be caused by internal dynamics, rather than external events such as weather or trade policies.

The team analyzed decades of daily futures prices for various commodities, including corn, soybeans, wheat, coffee, sugar, orange juice, hogs, and cattle. They used nonlinear analytical methods to identify patterns within price movements that traditional statistical techniques may have missed.

Mattos compared the market's internal dynamics to a traffic jam caused by individual reactions to unexpected events. He emphasized that external factors are still important but may not be as influential as previously thought.
