Maguire: Europe's next energy crisis is right in front of us.

The energy traders of Europe have been glued to Gulf maps in recent weeks. The Rhine should be on their radar.

The renewed 'confrontation' between Washington and Tehran is pushing oil prices up and reviving fears about the safety of shipping through Strait of Hormuz. But there is another threat that is much closer to home.

The water levels in key inland shipping gauges, including Cologne and Kaub (on the Rhine) and Budapest (on the Danube), have dropped to a level that is rarely seen except during major droughts. This has forced barges and their cargo loads to be reduced and increased transport costs.

Low rivers can be an inconvenience on their own. When combined with the rising geopolitical tensions of the Middle East they become more dangerous.

KEY TRADE ROUTES

The rivers of Europe are the secret arteries that run through its energy system. Fuel imported via Rotterdam and Amsterdam must still be transported inland to refineries and chemical plants, as well as industrial consumers.

Every ton of coal or diesel, gasoline, chemicals, biofuel, or other fuels that is not transported by barge requires additional vessels, higher rates, and longer delivery time.

While renewed U.S. Iran hostilities threaten oil flow through Hormuz once again and drive energy prices higher, Europe's shrinking waters risk turning an external shock into a much broader logistic crisis.

The timing of this attack could not be worse.

The Rhine is the most important commercial waterway in Europe. The Rhine is used by the German industry to transport around?200 millions of tons of goods each year, including fuels and industrial materials.

Water levels at Kaub, the most critical bottleneck on the river, have fallen to an exceptionally low level for July. This has forced vessels to sail partially loaded. Depending on the vessel type and route, some operators have reported freight reductions up to 80%.

The Danube also tells a story.

Budapest's water levels are now at lows that are more often associated with droughts in the late summer. Shipping companies report that vessels are operating at a fraction of their normal capacity. Freight surcharges have also risen as operators try to compensate for the reduced cargo volume.

Stress Test

The European energy system is increasingly dependent on flexibility in logistics.

After the loss of Russian pipeline gas to Europe, Europe rebuilt energy security by importing LNG, oil products, and alternative fuels via seaborne imports. As long as the cargoes can reach European ports, the markets will be adequately supplied.

Ports are just the beginning.

The Rhine links Germany's industrial heartland with North Sea import terminals. The Rhine is a major transport route for coal for power plants, chemical feedstocks and petroleum products for inland consumers.

When river levels collapse, cargo is shifted to rail and trucking systems that are already congested and expensive. It is not always a shortage. It is more often a dramatic rise in the cost of delivery that directly affects energy and industrial costs.

MOUNTING FEES

Economic damage is not a theoretical concept.

In previous Rhine droughts (notably in 2018), Germany suffered measurable industrial disruptions and losses of output.

This episode taught us that river levels are macroeconomic variables. When barges are not moving efficiently, industrial production, fuel distribution, and profitability all suffer.

Add the Middle East to your list.

The Strait of Hormuz is the world's largest oil transit chokepoint.

Oil prices have already risen due to attacks on ships, military strikes and increasing threats. Concerns about tanker movements are also back. The increased risk of a total closure will increase insurance, freight, and commodity costs.

The interaction of these two risks poses a danger to Europe.

Oil prices are usually absorbed. Usually, temporary shipping disruptions can be managed. Low river levels are usually manageable.

When all three occur simultaneously, however, the system is significantly less resilient.

European refiners could face higher crude prices?because there are tensions in the Gulf, while distributors struggle to move fuels into the inland due to restricted barge traffic.

Chemical producers may face rising feedstock costs at the same time as logistics costs rise.

Utility companies may find that alternative fuels are readily available in ports, but are more difficult and expensive to transport to the places where they are required. Each problem reinforces each other.

The energy supply chain in Europe is beginning to look like a funnel.

RISK STACK INTERTWINED

Ironically, policymakers are increasingly separating climate change from geopolitics and recommending separate solutions. Recent events indicate that they are becoming deeply intertwined.

Heatwaves and dry conditions are not only lowering Europe's river levels, but also increasing electricity demand. This puts pressure on the energy infrastructure.

Geopolitical conflict has also reduced the margin of error in global fuel markets. What appears to be a weather issue in Germany could quickly turn into an energy security concern across Europe.

It is important that traders pay attention to the river gauges in Kaub and Budapest, as well as to the missile launches taking place in the Gulf.

The other measures the risk of geopolitical conflict. One measures geopolitical risk.

For decades, Europe’s energy security was shaped primarily by tankers, pipelines and diplomacy. It may increasingly be shaped by rain.

As rivers shrink and conflicts increase, the continent learns an uncomfortable truth. Sometimes the most dangerous energy chokepoints are not halfway across the world but right in your backyard.
