How the Rhine drought threatens Germany's economic recovery

Low water levels on the Rhine River, a crucial artery for Germany's industrial goods, have reached critically low levels due to weeks of drought. At Kaub, a shallow stretch between Mainz and Koblenz, the water level stood at just 16 centimeters at Monday lunchtime, according to the Federal Waterways and Shipping Administration. This is considered the lowest mark for standard commercial vessels, with 40 centimeters being the minimum for safe passage.

Ship operators have reduced cargo loads significantly, in some cases to just one-fifth of normal capacity. The issue extends beyond the Middle Rhine, with many areas around Cologne, Düsseldorf, Duisburg-Ruhrort, and Emmerich experiencing historic lows. The Rhine may become impassable at Kaub by the end of the week, effectively splitting the river into two sections for commercial traffic.

This drought is occurring at a particularly challenging time for Germany's economy, already dealing with weak growth, high energy costs, and fading industrial competitiveness. Germany relies on its rivers and waterways to transport about 5% of its goods, including bulk materials like iron ore, coal, sand, and petroleum products.

In 2024, 173 million tons out of 3.28 billion tons of transported goods were carried by inland waterways. The Rhine corridor, stretching from the Netherlands to the German-Swiss border, handles around 40% of freight by ton-kilometers. For every 30 days of low water on the Rhine, Germany's industrial production declines by approximately 1%.

The German Economic Institute predicts a 0.4% drop in GDP, effectively erasing this year's expected growth. A prolonged river disruption could severely impact growth, with experts warning of potential losses of €1 to €2 billion in the third quarter, particularly affecting the steel, chemicals, and energy sectors.
