European Union leaders will meet in Brussels on 15–16 October under pressure to address surging energy costs, Russian hybrid attacks, continued support for Ukraine and the bloc’s next long-term budget. The summit comes as economic pressures expose growing differences between national governments.

European Union leaders are preparing for a two-day summit in Brussels dominated by the economic consequences of the Middle East conflict, Russia’s continuing war against Ukraine and mounting pressure on governments to reconcile defence commitments with deteriorating public finances.

The European Council meeting on 15–16 October will bring together the leaders of the 27 member states to consider immediate measures addressing high energy prices alongside longer-term decisions on competitiveness, enlargement, migration and the EU’s budget for 2028–2034.

European Council President António Costa has placed economic competitiveness and energy costs at the centre of the discussions, reflecting concerns that the disruption of global oil and gas markets is threatening the bloc’s industrial recovery.

The meeting also takes place against the background of renewed disputes over national spending limits, with Italy and Greece seeking greater freedom to finance energy relief and France facing increasing pressure over the credibility of its budget.

Energy crisis puts fiscal rules under pressure

The Middle East conflict has created a renewed energy shock for European economies, raising transport and industrial costs while pushing inflation higher.

The disruption of shipping through the Strait of Hormuz has also affected global oil supplies, exposing Europe’s continuing dependence on internationally traded fossil fuels despite efforts to diversify imports following Russia’s invasion of Ukraine.

European leaders are expected to consider targeted and temporary support measures for households and businesses, as well as longer-term policies intended to reduce energy dependence.

The political disagreement concerns how those measures should be financed.

The European Commission has resisted requests from Italy and Greece for further exemptions from the EU’s fiscal framework. Both governments argue that extraordinary energy costs require additional budgetary flexibility.

Brussels maintains that existing provisions already permit exceptional expenditure within defined limits.

The disagreement is particularly difficult for indebted governments that must simultaneously finance military expansion, maintain public services and protect their economies from energy inflation.

France’s position has added urgency to the debate. Its borrowing costs have increased sharply as investors question whether the government can adopt a credible budget ahead of the 2027 presidential election.

A summit agreement on emergency energy assistance would therefore have to accommodate substantially different national fiscal circumstances.

Ukraine and the changing transatlantic relationship

Support for Ukraine remains a central item on the summit agenda as Russia continues attacks against Ukrainian cities, energy infrastructure and industrial facilities.

EU leaders are expected to review military and financial assistance, the implementation of sanctions against Moscow and the resilience of Ukraine’s economy.

The discussions take place amid renewed uncertainty surrounding American weapons deliveries.

Washington’s reported threats to suspend supplies under the NATO-backed PURL procurement arrangement have raised further questions about Europe’s dependence on the United States for advanced military equipment.

European governments have increased defence expenditure and committed additional support to Ukraine, but replacing American capabilities remains difficult, particularly in air defence, precision-guided weapons and certain intelligence systems.

The summit is unlikely to resolve those industrial limitations, but the broader question of Europe’s ability to sustain Ukrainian defence over several years will influence discussions.

Member states must also consider how increased defence expenditure will be financed alongside other demands on national budgets.

Russian hybrid operations move higher on the agenda

The EU’s published summit agenda includes Russian-linked hybrid attacks within Europe.

The issue has gained prominence as European governments investigate sabotage, cyber operations, information interference and threats against infrastructure and defence-related industries.

Recent warnings concerning possible Russian assassination operations targeting European defence executives and employees of companies supplying Ukraine illustrate the changing nature of the security threat.

Such activities place additional demands on national intelligence services, police forces and European institutions responsible for cross-border cooperation.

The EU has strengthened its sanctions instruments against hybrid activities, but enforcement remains dependent on coordination between national authorities.

Any further measures would need to address intelligence sharing, protection of critical infrastructure and the relationship between internal security and the Union’s wider Russia policy.

A larger EU with a contested budget

Enlargement will form another important part of the discussions following the Commission’s proposals for preparing a wider Union.

Brussels has outlined possible institutional safeguards intended to prevent future members from undermining democratic standards or blocking common decisions.

Montenegro and Albania are advancing through their accession negotiations, while Ukraine and Moldova remain central to the EU’s geopolitical enlargement strategy.

The financial implications will become increasingly important as governments negotiate the next multiannual financial framework covering 2028–2034.

Existing members are already divided over how much the EU should spend, which programmes should receive priority and whether additional common resources should be raised.

Agricultural expenditure, cohesion funding, defence investment and support for Ukraine will compete for resources within the same budget negotiations.

The Commission argues that enlargement can be accommodated through targeted reforms, but securing agreement among member states will require decisions on future expenditure and the distribution of financial benefits.

Competitiveness and the single market

Leaders will also examine progress on the One Europe, One Market agenda, which aims to reduce barriers to economic activity within the EU and improve conditions for European businesses.

The initiative is intended to address structural weaknesses affecting investment, industrial development and the ability of European companies to compete internationally.

High energy prices have made those concerns more immediate, particularly for industries competing against producers in economies where electricity and fuel are cheaper.

The European Council will be asked to provide direction on measures planned for 2026 and 2027, but implementation will depend on subsequent legislation and decisions by member states.

The October meeting brings several unresolved European policy questions into the same negotiation: how to protect economic competitiveness, maintain fiscal credibility, finance defence, sustain Ukraine and prepare for enlargement.

The immediate test will be whether leaders can agree on a credible response to energy prices without reopening broader disputes over national budgets.

More difficult decisions concerning defence financing, institutional reform and the EU’s long-term expenditure commitments will extend well beyond the two-day summit.
