Record Lows at Kaub Chokepoint Halt Barge Deliveries to Thyssenkrupp Duisburg
Low Rhine levels at Kaub have stopped most commercial barge traffic, directly constraining feedstock to Duisburg steelworks. Historical GDP effects and current adaptation measures indicate a modest, concentrated Q3 impact unless water levels recover. The episode exposes Germany's dependence on a single, climate-sensitive inland waterway for bulk industrial inputs.
WSV forecasts and seasonal rainfall models point to continued sub-30 cm readings at Kaub through at least mid-September 2026. Thyssenkrupp output data for September will reveal whether the chartered fleet and modal shifts fully offset the shortfall or whether blast-furnace utilization declines.
WSV: Kaub gauge remains below 30 cm on at least 25 days between 11 August and 30 September 2026
