Europe’s expanding defence budgets are providing an unexpected source of support for the continent’s shrinking oil-refining industry, as military activity requires fuel for transport, logistics and equipment. The development comes as European governments increase defence investment after years of relatively limited spending, creating an additional demand channel for refined petroleum products even as the region continues its longer-term transition away from fossil fuels.

Defence Spending Creates Additional Fuel Demand

According to the Reuters report, the CEO of major European refiner VAROPreem said the continent’s refining sector is benefiting from increased fuel requirements associated with government defence plans. Military operations and the broader defence supply chain require significant quantities of diesel, jet fuel and other refined products, potentially supporting refinery utilization even as traditional European fuel demand faces structural pressure.

EU member states increased defence spending for an 11th consecutive year in 2025, reaching €418 billion, or 75% more than in 2021, according to the data cited by Reuters. Further increases are expected as European governments seek to strengthen military capabilities and expand defence procurement.

The broader trend is consistent with European Commission analysis showing that member states are entering a multi-year period of higher defence spending after years of underinvestment. The Commission has also introduced fiscal flexibility allowing qualifying increases in defence expenditure through 2028.

Refining Industry Faces Structural Challenges

The additional demand arrives at a critical point for Europe’s refining industry. Refiners are dealing with an evolving energy market in which long-term consumption patterns are being influenced by fuel efficiency, electrification, emissions policies and the broader shift toward lower-carbon energy sources.

That creates a complex operating environment. Higher defence-related fuel consumption can support refinery margins and utilization rates, but it does not necessarily reverse the structural factors that have contributed to Europe’s declining refining capacity. The industry therefore faces a distinction between short-term demand support and long-term market restructuring.

European refiners are also competing within a global market where crude supply, refining capacity and product flows can shift rapidly. Changes in European imports and exports can affect local margins even when domestic fuel consumption remains relatively stable.

Energy Security and Defence Are Becoming More Closely Linked

The relationship between defence spending and fuel demand also highlights the increasing overlap between Europe’s energy and security policies. Governments are seeking greater strategic resilience across defence supply chains while simultaneously trying to reduce dependence on vulnerable energy sources.

For the refining industry, this could create a more complicated investment environment. Higher defence demand may improve the economics of some existing facilities, while European policymakers continue to encourage investment in cleaner technologies and alternative energy systems. The European Commission estimates that defence spending can provide some additional economic activity, although it also increases government financing requirements.

Refiners Face a Demand Window, Not a Structural Reset

For investors in Israel and global markets, Europe’s refining sector illustrates how geopolitical developments can reshape commodity demand and industrial economics. Defence spending, fuel consumption, refining capacity and energy policy are increasingly interconnected, creating both support and uncertainty for European energy companies.

The key issue going forward will be whether higher defence-related fuel consumption becomes a durable source of demand or primarily provides temporary support while the region’s energy transition continues. Refinery closures, fuel margins, European defence procurement and government energy policies will remain important indicators of how this balance develops over the coming years.
