Market Participation and Open Interest

Open interest rose by 9,822 contracts on Friday, indicating modest new buying and a slight buyer‑bias in the market.

Markets are being buoyed by robust U.S. export performance and the increase in managed money long positions, fostering a short‑term upward trend in corn futures. However, limited rainfall in key U.S. regions and slower harvest progress in Brazil and Argentina introduce supply‑side uncertainty, potentially heightening volatility. Monitoring weather patterns and regional harvest data will be essential for positioning.
