Spain-Ukraine Agreement 2026: Real Opportunities for Spanish Companies

Key data

Spanish construction, engineering and infrastructure companies have had, since March 18, 2026, an operational legal framework to participate in technical and financial cooperation projects with Ukraine. The agreement, signed in Madrid and published in the BOE on March 31, 2026 (BOE-A-2026-7293), enters into provisional application immediately, meaning its legal effects are fully operative even though the parliamentary ratification process is still pending.

For executives and CFOs of companies with internationalisation capacity, this agreement is not a diplomatic formality: it is the gateway to tenders and contracts linked to one of the largest infrastructure reconstruction processes in Europe.

What does this regulation establish?

The agreement between the Kingdom of Spain and the Government of Ukraine establishes the bilateral legal framework for technical and financial cooperation between both countries. Its content covers three major operational areas:

• Fund transfers: Mechanisms to channel Spanish financing towards projects in Ukraine within the bilateral cooperation framework.
• Technical assistance: Participation of Spanish entities and companies in knowledge transfer, project management and specialised technical advisory services.
• Reconstruction projects: Access to tenders and contracts linked to infrastructure reconstruction, with particular relevance for the construction and civil engineering sectors.

The legal key to this regulation is its provisional application: the agreement produces full effects from the date of signature (March 18, 2026), without the need to wait for the conclusion of the parliamentary ratification process. This is standard practice in international agreements of this type and allows companies to act on a solid legal basis from the outset.

Economic and operational impact

The impact of this agreement is not measured in penalties or compliance costs: it is measured in business opportunities for Spanish companies with the capacity to operate internationally.

Ukraine is currently one of the largest potential infrastructure reconstruction markets in Europe. The bilateral agreement with Spain creates a preferential channel for Spanish companies and entities to access projects financed under this framework, competing with an advantage over companies from countries without an equivalent agreement.

The specific operational implications are:

• Access to tenders: Spanish public and private entities operating in strategic sectors will be able to participate in contracts linked to bilateral cooperation, backed by the legal framework provided by the agreement.
• Legal certainty: The established framework reduces contractual risk for companies already exploring projects in Ukraine, as they benefit from a state-level agreement supporting their operations.
• Early positioning: Since the agreement has been in provisional application since March 18, 2026, companies that act now have an advantage over those that wait for formal ratification.

Who is affected?

The agreement has a direct impact on the following business and institutional profiles:

• Construction companies with experience in civil works, building or transport and energy infrastructure.
• Engineering and civil engineering firms with international project management capacity.
• Consulting firms specialising in project management, international cooperation or post-conflict reconstruction.
• Spanish public entities with international activity (agencies, bodies, public enterprises) that can act as technical partners or financiers.
• Companies in strategic sectors with a presence or interest in the Ukrainian market: energy, water, telecommunications, logistics.

It does not directly affect companies without international activity or sectors unrelated to infrastructure or technical assistance.

Practical example

A Spanish civil engineering company with experience in transport infrastructure construction decides to explore its participation in reconstruction projects in Ukraine. Until now, the absence of a clear bilateral legal framework created uncertainty regarding contractual security and payment channelling.

With the agreement in force since March 18, 2026, this company can:

1. Identify tenders linked to the Spain-Ukraine technical and financial cooperation framework with state-level legal backing.
2. Negotiate contracts with Ukrainian counterparts based on the fund transfer framework established in the agreement.
3. Apply for technical assistance calls financed under this bilateral agreement, with a competitive advantage over companies from countries without an equivalent agreement.

The same approach applies to a consulting firm specialising in international cooperation project management, or to a company in the energy sector interested in critical infrastructure reconstruction projects in Ukraine.

What should companies do now?

1. Assess sectoral fit: Determine whether the company's activity aligns with the sectors covered by the agreement (construction, engineering, consulting, infrastructure, technical assistance) to evaluate whether there is a real participation opportunity.
2. Review internationalisation capacity: Verify that the company has the operational, financial and legal structure to participate in international projects, especially in a market with the specific characteristics of Ukraine.
3. Identify tender access channels: Contact organisations such as ICEX España Exportación e Inversiones or the Agencia Española de Cooperación Internacional para el Desarrollo (AECID) to obtain information on calls and projects linked to the agreement.
4. Establish contacts with Ukrainian counterparts: Take advantage of the active legal framework to initiate conversations with relevant Ukrainian entities, backed by the bilateral agreement.
5. Seek specialised advice: For companies that already have projects underway or in negotiation with Ukraine, review with legal advisors specialising in international trade how the new framework affects their current contracts and operations.
