The United States stopped sending about 20% of the natural gas it exports to Mexico. Cenagas said the system held up and that there are reserves for up to three days if supply is cut. Mexico depends on US gas for about 70%, according to Expansión. The government announced an investment of 1.16 trillion pesos in electricity and pipelines. Hurricane Isaías threatens US gas production. The S&P/BMV IPC fell 1.01% to 64,653 points and the peso closed at 17.98 per dollar, on a risk-off day driven by the war in the Middle East.
Imported gas underpins much of the country’s power generation and industry. Three days of reserves leave very little margin for any interruption.
A costlier or scarcer gas supply can translate into higher electricity rates for industry and, in time, into prices.
The government maintains that its investment plan will reduce the country’s vulnerability.
Analysts warn that the country has gone years without building storage and that the announced projects will take time.
What is urgent is not the trillions announced but storage: three days of reserves is a figure that should change before winter. Watch whether the US restores the flows after Isaías passes.

US cuts 20% of the natural gas it sends to Mexico. Cenagas says the country has reserves for three days
The cut exposed the country’s energy dependence on the same day the government touted a “historic” investment in electricity and gas, and the war in the Middle East hit the markets.
The United States stopped sending about 20% of the natural gas it exports to Mexico, El Financiero and Proceso reported. The National Natural Gas Control Center (Cenagas) said the system withstood the “heavy blow” and that the country has reserves for up to three days if imports are cut, according to El Universal and El Economista. Expansión noted that Mexico depends on US gas for about 70%, much of which is used to generate electricity. El Financiero devoted an analysis to why the country has so little storage reserve.
The same day, Claudia Sheinbaum and the Energy Ministry announced an investment of 1.16 trillion pesos in electricity and pipeline projects, which they called historic (La Jornada, El Economista, El Universal, El Financiero). Milenio reported that Sener projects 100 new power plants by 2027, and the ministry said electricity coverage has already reached 99.88% (El Universal). In the afternoon, Storm Isaías, which intensified into a hurricane in the Gulf of Mexico, also threatened US oil and gas production, El Financiero warned, which could complicate shipments to Mexico.
The markets reflected the nervousness. The escalation of the war in the Middle East and the attacks on ships in the Strait of Hormuz weighed on Wall Street, which closed lower (El Financiero, El Economista). The S&P/BMV IPC fell 1.01% to 64,653 points and snapped a three-day winning streak, according to Rio Times; the peso lost ground during the day and closed at 17.98 per dollar (La Jornada, Proceso, El Economista). The minutes of the Federal Reserve showed division among its members over the case for raising rates, El Economista reported. For Mexico, the combination is delicate: costlier energy, a gas supplier that puts its domestic market first, and a currency that depends on risk appetite. The official response bets on building the country’s own capacity, but the pipelines and plants announced will take years; the reserves, by contrast, are measured in days.
