Barge spot rates in St. Louis have significantly dropped to $72.58 per ton from a high of $105.85 per ton despite river challenges such as low water levels. This decrease is due to delayed deliveries by grain shippers. Despite the drop, rates are still 130% higher than last year and 260% higher than the 3-year average. The Federal Maritime Commission has proposed a rule to clarify demurrage and detention billing practices. In other news, Iowa has temporarily increased weight limits for vehicles transporting harvest-related goods until October 30, 2022. Finally, grain movements by ocean, rail, and barge have varied, showing increases in some areas and decreases in others compared to the previous week and the same period last year.
