Executive Summary
Water levels on Germany’s Rhine have fallen sharply again following dry weather, increasing transport costs and renewing pressure on one of Europe’s most important industrial logistics corridors.
At the critical Kaub chokepoint near Koblenz, the navigable gauge fell to approximately 15 centimetres on Monday, down from around 26 centimetres on Friday.
Official forecasts indicate extremely low levels continuing.
The figure does not mean the river itself is only 15 centimetres deep; the navigation channel is approximately one metre deeper than the gauge measurement.
However, low water restricts how deeply cargo vessels can sit in the river.
Ships must therefore reduce their loads substantially.
Freight costs for tanker transport from Rotterdam to Karlsruhe have risen to approximately €185-€190 per tonne, compared with around €180 last week.
Businesses have already shifted significant quantities of cargo to road and rail following repeated Rhine disruption this summer.
The problem is therefore becoming one of transport capacity as well as transport cost.
UK Impact
The Rhine is not a UK waterway, but it serves industrial regions deeply integrated with British supply chains.
Potential UK exposure includes:
- Chemicals.
- Automotive manufacturing.
- Steel.
- Construction materials.
- Fuel.
- Agricultural commodities.
- Industrial machinery.
UK businesses sourcing from Germany, Switzerland, the Netherlands or neighbouring industrial regions should establish whether suppliers depend upon Rhine transport.
A German supplier may remain fully operational but struggle to receive raw materials or dispatch finished goods economically.
Global Impact
The Rhine transports enormous quantities of:
- Chemicals.
- Petroleum products.
- Coal.
- Minerals.
- Grain.
- Steelmaking materials.
- Manufactured goods.
Some industrial businesses have already experienced production constraints during this summer’s exceptionally low water.
Alternatives are limited.
One fully loaded barge can carry the equivalent of dozens — and for some cargoes well over 100 — truckloads.
Moving river freight onto roads and railways therefore creates secondary pressure on:
- Truck availability.
- Rail capacity.
- Fuel.
- Warehousing.
- Driver availability.
- Freight rates.
Low Rhine water can consequently transmit through supply chains even where companies never use river freight directly.
Our View
Businesses should treat inland waterways as critical infrastructure.
Companies should ask:
- Do German suppliers use the Rhine?
- Where do their raw materials arrive?
- Which products leave by barge?
- Are vessels currently sailing part-loaded?
- Have freight rates increased?
- Can contracts pass through transport surcharges?
- Is rail capacity available?
- Is road capacity available?
- How many trucks would replace one normal barge movement?
- Are storage tanks sufficiently stocked?
- Could suppliers reduce production?
- Are chemicals particularly exposed?
- Could fuel deliveries become constrained?
- Is additional inventory justified?
- What happens if water levels remain low into October?
- Are alternative suppliers genuinely outside the affected logistics corridor?
There is an important resilience lesson.
A supply chain can have several alternative modes of transport without having sufficient alternative capacity.
A theoretical ability to switch from river to road or rail is not the same as having enough trucks, trains, drivers and terminal capacity available when thousands of other businesses attempt the same switch.
