A commodities researcher said traders can often reroute cargoes or switch origins, keeping shipping disruptions regional rather than causing a broad rise in grain futures. He added that hedge-fund selling in wheat, corn and soybeans has outweighed logistics concerns, although route-specific freight costs and cash-market differentials may still rise.
Rerouting and alternative suppliers limit global supply disruption, reducing the chance of a broad futures rally; local freight and delivered costs can nevertheless increase. Fund selling adds downward pressure to futures.
