If Donald Trump imposes a 30% tariff on all Mexican exports to the U.S., the cost to American importers would be around $150 billion USD, according to economist Enrique Quintana. The idea originated from a letter Trump sent to Mexico’s President Claudia Sheinbaum, accusing the country of failing to curb fentanyl trafficking.

In 2024, Mexican exports to the U.S. totaled over $503 billion, making the potential impact of such a tariff massive. The uncertainty lies in whether the tariff would apply to all exports or only those outside the USMCA framework. If it includes all products, the tariff would severely disrupt trade.

The Mexican strategy appears to rely on economic pressure from U.S. companies to prevent implementation of the tariff, due to the direct financial damage they would suffer.

The Mexican government reaffirmed that aviation safety is a national priority. During the “Airport Day ACI-LAC México 2025,” the Ministry of Infrastructure, Communications and Transport (SICT) emphasized its commitment to continuous improvement in airport security and aviation regulation.

The event brought together key players in Latin American civil aviation to exchange best practices, highlighting Mexico’s ongoing efforts in collaboration with the International Civil Aviation Organization (ICAO) to maintain safety standards.

Lenia Batres Guadarrama, Minister of the Supreme Court, criticizes the current imbalance in Mexico’s fiscal litigation system. While taxpayers have multiple legal avenues to contest tax resolutions — including direct appeals, nullity trials before the TFJA, and constitutional appeals — the tax authority (SAT) is significantly limited in challenging court rulings that favor taxpayers. 

Judicial precedents have increasingly protected taxpayers, especially those from the middle class, from unjust or improperly reiterated tax charges. The minister urges a shift toward a more equitable and proportional approach in tax collection and calls for reviewing the over 1,800 existing rulings that currently favor non-payment of certain taxes.

Mexico’s Chamber of Deputies approved a reform to eliminate the Federal Economic Competition Commission (Cofece) and replace it with a new National Antitrust Commission under the Secretariat of Economy. Unlike Cofece, which had constitutional autonomy, the new body will report directly to the Executive.

The reform passed with 323 votes in favor and 125 against. Supporters (Morena, PT, PVEM) claim it will strengthen enforcement against monopolies. Opposition parties argue it undermines independence and violates international agreements like the USMCA.

The reform now moves to the Senate.

On June 30, 2025, the Mexican government officially completed the merger of three entities: AICM (Mexico City International Airport), GACM (Grupo Aeroportuario de la Ciudad de México), and SACM (Servicios Aeroportuarios de la Ciudad de México). This fusion gives rise to Grupo Aeroportuario MARINA, which will now oversee operations and infrastructure previously managed by the other two entities.

The new group will control multiple airports (CDMX, Colima, Ciudad del Carmen, Obregón, Guaymas, Loreto, Matamoros), plus stakes in Toluca and Cuernavaca airports. It will also support operations in Lázaro Cárdenas and San Felipe. The group inherits all rights and obligations, including revenue from airport usage fees (TUA) used to repay MEXCAT bonds.

This restructuring aims to improve financial efficiency, operational capacity, service quality, and national connectivity.

Mexico’s Senate approved a law that gives the federal government full control over regulation and citizen data, including biometric information. The Executive will no longer require input from independent bodies or civil society.

Experts and rights groups warn the law could lead to mass surveillance and data misuse, as it lacks transparency and external oversight. While the government claims it will streamline services and reduce corruption, critics say it centralizes power dangerously.

The Mexican peso and the Mexican Stock Exchange (Bolsa Mexicana de Valores) declined after a U.S. airstrike on Iran, triggering increased risk aversion in global markets. The peso depreciated by 0.32% to around 19.2163 per U.S. dollar, while the stock market also dropped as investors reacted to the geopolitical shock.

Analysts believe this reflects a shift toward safe-haven assets amid heightened uncertainty. The conflict’s potential economic ripple effects—on inflation, energy prices, and market stability—may influence future monetary policy if tensions persist.
