Introduction
The European Council of 18 December not only brought the EU’s political year to a close; it also consolidated a new internal balance within the European Union that compels Member States to recalibrate their positions. For Spain, this Council came at a particularly sensitive moment: amid a deteriorating geopolitical environment, a more intergovernmental EU, and a strategic agenda shaped by security, enlargement, and competitiveness. The decisions taken do not abruptly alter Europe’s trajectory, but they do redefine the real margins of influence available to Member States—and it is precisely within those margins that Spain’s position is at stake.
Spain approaches this new balance from a paradoxical standpoint. It maintains a clearly pro-European discourse, aligned with deeper integration, yet operates within a Union where minimal consensus and defensive logic prevail over integrative ambition. The December Council confirms that the EU is moving forward, but cautiously—and that caution constrains Spain’s diplomatic room for manoeuvre.
A Council That Reinforces the Intergovernmental Axis
The Council’s conclusions once again underscore the central role of heads of state and government as the true decision-makers. Defence, Ukraine, enlargement, economic governance, and migration are addressed through a balancing of national interests, with the Commission acting more as a manager than as a driving force.
For Spain, this reinforcement of the intergovernmental method has a dual reading. On the one hand, it limits Brussels’ capacity to exercise supranational leadership—an arena in which Spain has traditionally found a favourable framework. On the other, it opens space for active diplomacy within the Council, provided there is sufficient capacity for dialogue and stable alliances. Spain’s challenge is to turn this less normative environment into an opportunity for direct political influence.
Security and Ukraine: Alignment without Leadership
The Council reaffirmed the EU’s commitment to Ukraine, a position with which Spain fully aligns. However, the debate made clear that political and operational leadership remains concentrated within a small core of Member States. Spain supports, contributes, and endorses—but does not set the agenda.
This secondary role is not the result of a lack of political will, but of a combination of factors: a more limited defence industrial base, a geographical position less directly exposed to the conflict, and strategic priorities focused on other fronts. The new European balance consolidates a Union in which security is managed through coalitions of states rather than collective leadership. Spain must decide whether to accept this role or to strengthen its defence profile in order to gain political weight.
European Defence: A Conditional Opportunity
The Council’s emphasis on the European defence industrial and technological base opens a window of opportunity for Spain. The country has relevant industrial capabilities and a key geostrategic position, but its influence will depend on its ability to link industry, diplomacy, and strategy.
The new European balance favours states that translate discourse into tangible capabilities. For Spain, this implies domestic decisions on investment, public–private coordination, and strategic ambition. Without such a leap, its role will remain that of a reliable partner—but not a decisive one.
Enlargement: Proactive Rhetoric, Deferred Costs
Spain has historically been one of the strongest supporters of EU enlargement, and the December Council reinforces this stance. Support for Ukraine, Moldova, and the Western Balkans aligns with Spain’s vision of an open and geopolitically relevant Europe.
However, the Council also confirms that enlargement is advancing without a clear institutional reform. For Spain, this creates a dilemma: politically supporting the process while the budgetary and governance implications—ultimately affecting Spanish interests—remain unresolved. The new European balance allows for a pro-enlargement discourse, but shifts the costs to the medium term, when negotiations will be more complex and less symbolic.
Economic Policy and Fiscal Governance: An Uneasy Balance
On economic matters, the Council opted for a cautious application of the new fiscal framework, combining discipline with flexibility. Spain, with an economy still sensitive to cycles and social pressures, occupies an intermediate position between more fiscally conservative states and those calling for greater budgetary leeway.
The new European balance favours technical and gradual solutions, giving Spain some room to argue for flexibility without appearing as a dissenting actor. Nevertheless, the lack of clear progress on own resources and the EU budget limits the Union’s ability to sustain new priorities—a constraint Spain shares and one that narrows its room for manoeuvre.
Competitiveness and Regulatory Fatigue: A Shift in Tone
The December Council reflected a clear change in tone regarding regulation and competitiveness. The EU is entering a phase of regulatory review and restraint, driven by pressure from Member States and the productive sector. For Spain, this shift has direct implications.
On the one hand, it eases tensions in sensitive sectors and reduces the risk of social backlash. On the other, it requires greater national adaptability to take advantage of a less prescriptive and more competitive European environment. The new balance benefits countries capable of translating flexibility into growth and penalises those overly dependent on the EU regulatory framework.
Migration: Functional Consensus, Absent Leadership
The Council reaffirmed the implementation of the Migration and Asylum Pact, with a strong focus on border control and cooperation with third countries. Spain, as a frontline migration country, shares elements of this approach, but the new European balance reduces the space for structural solutions based on solidarity.
Migration management has consolidated as an area of minimum consensus. Spain will need to continue combining European alignment with bilateral and regional initiatives, aware that EU-level leadership in this field remains limited.
Spain in a More Pragmatic EU
The December Council confirms that the EU is entering a phase of defensive pragmatism. For Spain, this context demands a less declarative and more strategic diplomacy. Europeanism is no longer measured by rhetorical alignment, but by the ability to exert influence within a system where power is more fragmented.
Spain possesses clear assets: European credibility, mediation capacity, international projection, and institutional experience. But the new European balance penalises inertia and rewards initiative. Turning presence into influence will be the central challenge.
Key Takeaways
Context
The December European Council consolidates a more intergovernmental, cautious EU, oriented towards minimal consensus in an adverse geopolitical and economic environment.
Implications
Spain navigates between pro-European alignment and the need to strengthen its strategic profile in order to avoid being relegated to a secondary role in major decisions.
Outlook
Spain’s ability to influence the new European balance will depend on its ambition in defence, its economic pragmatism, and its skill in building alliances within an increasingly decisive Council.
