The Mexico foreign investment reform now moves to the lower house, after senators brushed aside warnings that it militarises economic decisions.
Mexico’s Senate approved a reform of the Foreign Investment Law on Wednesday 30 September 2026 by 65 votes to 30. The bill gives the Defence Ministry, the Navy and the Security Ministry a vote on foreign takeovers of strategic companies.
A clear majority, and a split along party lines
The ruling Morena party and its allies supplied the 65 votes in favour, El Universal reported. The conservative National Action Party (PAN), the centrist Institutional Revolutionary Party (PRI) and the centre-left Citizens’ Movement (MC) voted against.
PRI and MC senators proposed changes to individual articles, but the chamber rejected them all. The text then passed article by article by 65 votes to 28, the Senate said in a bulletin.
President Claudia Sheinbaum sent the bill to Congress in late August. Two Senate committees cleared it on 29 September, as The Rio Times reported when the reform reached the Senate floor.
Who decides on a foreign takeover
The bill enlarges the National Foreign Investment Commission (CNIE), the cabinet-level body that rules on foreign stakes in Mexican companies. Its member ministries rise from 10 to 13, 24 Horas reported.
The new voters are the Defence Ministry, which runs the army and air force, the Navy Ministry and the Security Ministry. The Digital Transformation and Telecommunications Agency also gets a vote.
In security cases, four more bodies take part with a voice but no vote. They are the attorney general’s office, the National Intelligence Centre, the SAT tax authority and the Financial Intelligence Unit.
The president can also be called to a meeting in exceptional cases, the Senate said. In security matters no member may abstain, and decisions are taken by simple majority, 24 Horas reported.
Which deals fall under the new review
Approval is needed only when three conditions meet. A foreign investor must seek more than 49 percent of a Mexican company. The company’s assets must also exceed a threshold the commission will set later.
The company must also work in a strategic field. The list includes energy, transport, health, communications, mining, data storage, digital systems, aerospace and defence, according to 24 Horas.
Critical technologies are covered too, from artificial intelligence, robotics and semiconductors to cybersecurity, quantum and nuclear technology. Energy and raw-material supply, food security and access to personal data complete the list.
The commission can approve a deal, attach conditions to reduce risk, or block it on security grounds. Stakes of 49 percent or less fall outside the new review.
Fines and a duty to report
A Mexican company that hands shares to a foreign buyer without approval faces a fine. The same applies if it ignores conditions the commission imposed.
In both cases the fine runs from 5,000 to 200,000 times the daily value of the UMA. The UMA is the official reference unit that replaced the minimum wage for setting fines.
The commission must also report to Congress every six months on its security reviews. Its members can be called to appear before the relevant congressional committees, the Senate said.
Supporters: open to money, firm on control
Senator Emmanuel Reyes Carmona of Morena, who chairs the Economy Committee, rejected the charge of militarisation. He called the military‘s role limited, proportionate and legally grounded, in a body that stays mainly civilian and economic.
Reyes compared the design to the Committee on Foreign Investment in the United States, Washington’s own screening body. Protecting the state is not at odds with attracting foreign money, he said, according to the Senate.
Senator Manuel Huerta Ladrón de Guevara, who chairs the Legislative Studies Committee, said Mexico wants more investment, technology and jobs. The reform defines the tools the country needs when investors target strategic sectors, he said.
Senator Octavia Hernández Farret of Morena argued the rules could encourage Mexicans living abroad to invest at home. Senator Juanita Guerra Mena of the Green Party (PVEM), a Morena ally, said technology must be both promoted and regulated.
Critics: the army has no place in investment policy
Senator Luis Donaldo Colosio Riojas of MC told the chamber the reform militarises the economy. The armed forces will help decide who invests in Mexico, he said, according to El Universal.
His party colleague Francisco Daniel Barreda Pavón said Mexico does not need to militarise investment policy to protect national security. The military should step in only when a deal touches defence or critical infrastructure, he argued.
Senator Miguel Márquez Márquez of the PAN said security checks need a special procedure. Placing the military in the commission’s ordinary work does not help attract capital, he said.
Senator Claudia Edith Anaya Mota of the PRI asked for strict limits on the armed forces’ role. “Let us be very strict and precise about what they can and cannot do”, she said.
What comes next for investors
The bill now goes to the Chamber of Deputies, Mexico’s lower house. It becomes law only if deputies approve it and the president signs it.
The asset threshold that triggers a review has not been set; the commission will fix it after the law takes effect. Until then, investors cannot tell exactly which mid-sized deals the new filter will catch.
For most foreign residents and small investors, little changes, because the rule targets control of large companies in sensitive sectors. For buyers of Mexican energy, data or mining firms, approval would become a security question as well as an economic one.

Frequently Asked Questions
Is the Mexico foreign investment reform already law?
No. The Senate approved it on 30 September 2026. The Chamber of Deputies must also pass it, and the president must sign it.
Does the reform affect small foreign investors or home buyers?
The new review covers foreign stakes above 49 percent in large Mexican companies in strategic sectors. Smaller stakes and companies outside those sectors are not affected.
Why are the Defence Ministry and the Navy involved?
The government says national-security risks from foreign takeovers need security expertise inside the commission. Opposition parties PAN, PRI and MC say this gives the armed forces too much say over economic decisions.
