Foreign Investment Reform Tightens Scrutiny and Sets Fines of 23.5M Pesos

Sheinbaum's reform tightens scrutiny of foreign investment, brings Defense and the Navy onto the oversight body, and sets fines of up to 23.5 million pesos. Here is what is changing.

The amendment to the Foreign Investment Law that President Claudia Sheinbaum submitted to the Senate on August 30 requires, on national security grounds, that any foreign investment exceeding 49% of a Mexican company's capital obtain a favorable ruling from the National Foreign Investment Commission.

The bill arrives days before Mexico and United States teams meet in Washington for the fourth round of the joint USMCA review, and aligns oversight of foreign acquisitions with regimes already in place in the United States, the European Union, and much of the OECD. According to Bloomberg Línea, Foreign Direct Investment reached $34.968 billion in the first half of 2026, 2.1% more than the same period in 2025 and the highest level for a first half on record. For the Mexican-American business community operating on both sides of the border, the reform defines the rules under which foreign capital will be assessed in strategic sectors.

The National Foreign Investment Commission will gain voting members in the form of the heads of Defense, the Navy, and Public Security and Citizen Protection, joining the eleven secretariats already on the body. A new national security chapter on foreign investment empowers the Commission to approve or deny foreign participation when it exceeds 49% of share capital, or when the company operates in sectors such as energy, artificial intelligence, semiconductors, cybersecurity, and mining. According to El CEO, fines range from 5,000 to 200,000 times the daily value of the UMA, which at the 2026 UMA value of 117.31 pesos translates to a range of 586,550 to 23.5 million pesos for companies that transfer shares despite an adverse ruling. On the eve of the fourth USMCA round, economist Gabriela Siller of Banco Base noted that the bill could add regulatory uncertainty to the attraction of Foreign Direct Investment.

The reform will be debated in the new congressional session opening this month, as USMCA negotiations continue in Washington, where economic security is on the agenda. The outcome will set the rules that Mexican and American investors must navigate in strategic sectors for years to come.
