Record-low Rhine water levels threaten German economic recovery

The Rhine, Germany's most important inland waterway, is in the grip of an extreme drought that has pushed water levels to critical lows across much of its length. At the key measuring point of Kaub — located between Mainz and Koblenz and closely watched by shipping operators — the gauge stood at just 16 centimetres above zero on Monday afternoon, according to federal waterway authority data. The actual navigable depth in the fairway remains above one metre, but conditions are deteriorating rapidly.

Freight carriers forced to slash loads

Media reports indicate that cargo companies have drastically cut the loads their vessels carry on the Rhine in recent weeks — in many cases to just one-fifth of normal capacity — to avoid running aground. The head of the Federal Association of German Inland Navigation, Jens Schwanen, warned that the river near Kaub could become impassable for commercial traffic before the end of the week, effectively splitting the Rhine into a navigable upper section and an inaccessible lower stretch.

Broad economic ripple effects

The Rhine carries roughly five percent of all goods transported within Germany. Industries most exposed include chemicals, energy commodities — particularly coal for power plants — and agricultural products. Low water on the Rhine was a significant factor in Germany's economic troubles in 2018 and again in 2022, when the bottleneck cost the economy billions of euros. Analysts warn that a repeat could further delay a recovery already struggling against weak domestic demand and slow export growth.

The drought is expected to persist for at least several more weeks, according to meteorological forecasts, with no significant rainfall anticipated for the Rhine catchment area in the near term.
