Investment radar: Tania Carro Toledo and the legal shielding of infrastructure in Mexico

A 5.6 trillion peso plan redefines the legal structuring of infrastructure in Mexico

Mexico will allocate 5.6 trillion pesos, approximately US$325 billion, to public and mixed infrastructure investment between 2026 and 2030, according to the Ministry of Finance and Public Credit (SHCP). The magnitude of this fiscal commitment demands a legal structuring chain without recent precedent in Latin America. Profiles such as Tania Carro Toledo, Undersecretary of Communications and Transportation at the Ministry of Infrastructure, Communications and Transportation (SICT), and private sector experts like Marcelo Mor at Alvarez & Marsal, along with Notary Office 1 of Mexico City, are positioning themselves as central gears in that process.

The projected volume of resources turns the legal shielding of each project into a critical variable for investor legal certainty. In this context, the ecosystem of lawyers, notaries, and advisors specializing in concession structuring and mixed investment acquires a relevance that transcends the technical realm and enters strategic territory.

Who is Tania Carro Toledo and what is her role in the infrastructure pipeline?

Tania Carro Toledo serves as Undersecretary of Communications and Transportation at the SICT of the Government of Mexico, leading mobility and infrastructure safety projects, according to official information from the ministry itself. Her position places her at the center of executing a plan that, according to the SHCP, will allocate 16% of the 2026-2030 resources to railways and 14% to highways.

These two segments, rail mobility and highway connectivity, account for nearly one-third of the total budget of the Infrastructure Investment Plan for Development with Well-Being. The undersecretariat led by Carro Toledo is the direct institutional counterpart for the legal and financial structurers seeking to participate in tenders and mixed investment schemes.

The relevance of Carro Toledo's profile lies in the fact that every transportation project advancing toward execution requires technical, environmental, and legal feasibility assessments before contracting. In an administration driving a new regulatory model, the dialogue between the undersecretariat and private legal advisors is decisive for the speed of capital deployment.

The paradigm shift: from PPPs to mixed investment

Claudia Sheinbaum's administration has distanced itself from the traditional Public-Private Partnership (PPP) model regulated by the Public-Private Partnership Law (LAPP), currently in force but subject to reforms. Instead, it is promoting a Bill for Strategic Infrastructure Investment, already submitted to the Chamber of Deputies, which establishes a "mixed investment" regulatory framework designed to avoid costly indebtedness and long-term concessions.

This initiative proposes the creation of Special Purpose Vehicles and a Strategic Planning Council for Infrastructure Investment. The transition from one model to another generates extraordinary demand for specialized legal advisory services. Private equity funds, family offices, and institutional investors need contractual certainty to commit resources to instruments that lack consolidated case law.

The legal structuring of Special Purpose Vehicles constitutes the most sensitive link in Mexico's new infrastructure investment architecture. Without robust contractual frameworks, private capital will hardly flow toward projects operating under rules still being written.

Which players shape the infrastructure legal shielding ecosystem?

Three recurring names emerge in the mapping of Mexico's legal and notarial infrastructure structuring chain. Marcelo Mor, affiliated with the firm Alvarez & Marsal, has been identified as a key player in the legal structuring of infrastructure projects, according to GRI Hub News reports from March 2026. Notary Office 1 of Mexico City fulfills a complementary role in the notarial formalization of highly complex contracts, an indispensable step in the legal value chain of any large-scale project.

On the capital side, Arzentia Capital operates as a family office and private equity fund in Mexico, with active participation in the investment ecosystem through the Mexican Private Equity Association (AMEXCAP), according to the association's own information from 2026. The presence of vehicles like Arzentia in the ecosystem confirms that Mexican private capital is seeking early positioning in the new mixed investment model.

The legal shielding ecosystem does not operate in isolation. Advisory firms, specialized notary offices, and investment funds form an interdependent chain where the failure of one link can paralyze entire projects. The sophistication of the new regulatory framework raises barriers to entry for generalist advisors and favors specialists with infrastructure experience.

The initial 2026 disbursement: pressure on the legal chain

The Government of Mexico foresees an additional initial disbursement of 722 billion pesos in 2026 to revive infrastructure investment, equivalent to roughly 2% of GDP, according to the SHCP. This capital injection in a single fiscal year places considerable pressure on the country's installed legal structuring capacity.

54% of the five-year plan's resources will go to energy, according to the SHCP, positioning the electricity and hydrocarbons sector as the leading consumer of specialized legal services. The railway segment, at 16%, and highways, at 14%, round out the three verticals with the highest projected contracting volume.

The concentration of 54% of investment in energy means that law firms capable of structuring contracts under the new mixed investment model in that sector will hold a decisive competitive advantage over the next four years.

For private equity funds and family offices like Arzentia Capital, the speed at which the regulatory framework consolidates will determine the pace of capital deployment. The Bill for Strategic Infrastructure Investment remains in the legislative process, and its approval will define the rules of the game for the Special Purpose Vehicles that will channel mixed investment.

Implications for the legal structuring market

The projected investment volume and the complexity of the new regulatory framework shape a specialized infrastructure legal services market with distinctive characteristics. Demand is concentrated in profiles capable of operating simultaneously across administrative, financial, corporate, and regulatory law. The professionals and firms that manage to position themselves at the intersection of these disciplines will capture a significant share of the fee flow associated with the 5.6 trillion peso pipeline.

From the perspective of the GRI Institute, which brings together real estate and infrastructure leaders in Latin America, the Mexican case illustrates a regional trend: the growing professionalization and specialization of the legal structuring chain as a prerequisite for the financial viability of major projects. GRI Institute meetings and forums have reflected this dynamic, with an increasingly active presence of legal advisors, notaries, and specialized funds in discussions about the future of Latin American infrastructure.

The Mexican pipeline does not merely represent an investment opportunity. It also constitutes a regulatory laboratory whose lessons — on Special Purpose Vehicles, mixed investment, and contractual shielding — will be watched closely by Colombia, Peru, and Chile as those countries evaluate reforms to their own PPP frameworks.

Mexico is building, in real time, the institutional and legal architecture that will determine whether 5.6 trillion pesos are transformed into operational infrastructure or remain as budgetary projections. The answer will depend, to a great extent, on the legal ecosystem's capacity to rise to the challenge.
