In 2025, Mexico's reliance on natural gas imports from the United States surged once again, as reported by the International Energy Agency (EIA). The country averaged imports of 6,638 million cubic feet per day (MMcfd), marking the highest level recorded and a new historical peak in external energy purchases. This trend of increasing imports has been observed for three consecutive years but showed a slightly moderated growth rate of 3.4% in 2025, compared to a 4.5% rise in 2024.

The significant uptick in imports can be linked to extreme heatwaves that occurred in May 2025, which pushed natural gas imports from the US to an unprecedented 7.5 billion cubic feet per day during that month. This spike illustrates the increasing demand for natural gas in Mexico, which is being driven by both climate conditions and the overall energy needs of the country. The sustained growth in imports highlights Mexico's ongoing dependence on US natural gas, raising questions about energy security and the potential implications for domestic energy policy.

This scenario presents both challenges and opportunities for Mexico as it continues to navigate its energy landscape in the context of increasing import levels. Policymakers may need to address the vulnerabilities associated with such dependence while also considering efforts to enhance domestic production capabilities in the future. The evolving dynamics of the natural gas market in North America will likely influence energy discussions and decisions in both Mexico and the US.
