Hot, dry weather is pushing the Ohio and Mississippi rivers toward low-water levels, with the Ohio near Cairo expected to fall a further four feet before month-end. Forecasts show the Mississippi receding about three feet at St Louis and six feet near Memphis.
Shippers fear a repeat of 2022, when low water cut barge payloads by 20-27% and stranded barges during peak grain shipments.
Lower river levels reduce barge payloads and raise freight costs, which can lift delivered prices for corn and soybean meal into southern and export markets. Restricted barge capacity can also slow US soybean exports, supporting domestic soy prices relative to Gulf export basis.
