After the Thaw: Spain and Mexico Pivot From Diplomacy to Institutions and Business

From a Royal Thaw to an Investment Agenda

The June meeting between King Felipe VI and Mexican President Claudia Sheinbaum has formally closed a diplomatic rupture that began in 2019, when then-President Andrés Manuel López Obrador demanded that Spain apologize for the conquest. The freeze deepened with accusations against Spanish companies, a proposed pause in bilateral relations and the king's absence from Sheinbaum's inauguration in 2024.

Business, however, never stopped. Mexico's Economy Secretariat reports Spanish investment in 2025 at $4.431 billion, second only to the United States, with cumulative investment since 1999 above $80 billion. BBVA and Santander hold strategic positions in Mexican finance; Acciona, ACS, CAF and Naturgy operate in infrastructure and energy; and Inditex, Meliá and Mapfre are part of the country's daily economy.

Mexico remains an attractive platform: more than 130 million inhabitants, deep integration with the US economy through the T-MEC, and a nearshoring push accelerated by US-China trade tensions. It needs more infrastructure, electricity networks, water, logistics and digitalization, all sectors where Spanish companies have extensive international experience. The new EU-Mexico Global Agreement removes almost all tariffs and opens public contracts.

Yet the article warns that diplomatic normalization is not an automatic guarantee of new investment. Mexico faces legal uncertainty over judicial reform and past energy regulation, and organized crime continues to raise costs. Spain must run active economic diplomacy, while its companies will need to integrate deeply into the local economy.

Why Spanish Capital Kept Flowing While Diplomacy Froze

An $80bn Relationship That Politics Could Not Freeze

The investment numbers show a striking gap between diplomacy and business. Even during the worst political period in decades, Spanish companies continued investing, hiring and expanding in Mexico. The presence of BBVA, Santander, Acciona, ACS, CAF, Naturgy, Inditex, Meliá and Mapfre indicates that the economic relationship was far more solid than the political one, and that multinational boards were pricing policy risk rather than abandoning the market.

Nearshoring Turns Mexico's Infrastructure Gaps Into Spanish Opportunities

US-China trade tensions are accelerating the relocation of production closer to the North American market, and Mexico is a primary beneficiary. The article identifies electricity, water, logistics and digitalization as the gaps Mexico must close to consolidate its industrial role. Those are exactly the sectors in which Spanish engineering, infrastructure and energy groups have accumulated international expertise, making this a structurally aligned opportunity rather than a rhetorical one.

The EU-Mexico Agreement Gives Spain a Head Start, Not a Guarantee

The new global agreement between the European Union and Mexico removes almost all tariffs, facilitates access to public contracts and improves the framework for services and investment. Spain enters that competition with decades of local presence, market knowledge and cultural proximity. But the article is clear: executives do not decide on the basis of official photographs. They decide on institutional stability, predictable rules and independent courts.

Judicial Reform and Security Are the Real Filters

Mexico's judicial reform, which introduces the popular election of judges and magistrates, divides opinion politically. From a business perspective the test is simpler: investments require stable rules, independent courts and guarantees that contracts will be respected. Security is another cost. Large multinationals can manage organized-crime risk in regions, but it remains a substantial barrier for small and medium-sized Spanish firms seeking to internationalize.

What Spanish Boards and Mexican Policymakers Do Next

For Spanish businesses and Mexican policymakers, the thaw changes the political backdrop, not the underlying return equation.

• Spanish infrastructure, energy and logistics groups should tie any new Mexican capacity to the specific gaps the article identifies, electricity networks, water, logistics and digitalization, where nearshoring demand is rising.
• Legal teams should stress-test contracts against Mexico's elected-judge reform and recent energy-sector regulatory reversals, rather than treating the June meeting as evidence of legal stability.
• Small and medium-sized firms considering entry need to price in organized-crime costs explicitly; unlike large multinationals, they lack the scale to absorb security risk across regions.
• Spanish economic diplomacy can invoke the EU-Mexico Global Agreement, including tariff elimination and access to public contracts, if Mexican regulators make discriminatory or destabilizing decisions affecting Spanish investment.
• Mexican policymakers can convert diplomatic goodwill into investment only by strengthening predictable rules, judicial independence and contract enforcement. Without that, the $4.431 billion annual flow will remain below Mexico's potential.
