Mexico Proposes National Security Review for Foreign Investment
A new bill submitted to the Mexican Senate would establish a formal process for screening foreign acquisitions in sensitive sectors, formalizing a power the government has rarely used.
On August 30, 2026, Mexican President Claudia Sheinbaum's administration submitted a legislative initiative to the Senate to reform the country's Foreign Investment Law. The proposal aims to create a formal national security screening mechanism for foreign investments in sectors deemed sensitive.
While Mexico's National Commission of Foreign Investment technically has the authority to block foreign acquisitions on national security grounds, this power has been seldom used due to the absence of clear parameters and guidelines. The proposed reform would operationalize this review process, creating new regulatory hurdles and potential uncertainty for cross-border transactions. The development aligns Mexico with a global trend toward more robust foreign investment screening regimes, such as the Committee on Foreign Investment in the United States (CFIUS).
Counsel for clients involved in M&A, supply-chain nearshoring, and other direct investment into Mexico should monitor the bill's progress. The eventual definition of 'sensitive sectors' and the specific procedures for review will be critical details affecting deal timing, risk allocation, and transaction structures.
