This study introduces a novel approach to analyzing convenience yield dynamics in commodity markets by leveraging sentiment analysis, enabling a more granular understanding of convenience yield dynamics in corn and soybean markets.

The Global News Index developed by the Cline Center for Advanced Social Research at the University of Illinois is used to track global news attention to commodity markets. Futures prices and implied volatilities for corn and soybean are extracted from Bloomberg.

No significant, immediate, and consistent responses are observed in convenience yield. Implied volatility tends to respond negatively by 0.5 to 1.5 percentage points to shocks in news sentiment, specifically in financial and soybean-specific news shocks.
