US and Mexico Reach Water Agreement Amidst Trump Tariff Threat
A new understanding on water management in the Río Bravo basin was reached Friday, averting a potential 5% tariff on Mexican products threatened by former President Donald Trump.
Mexico and the United States have reached an agreement regarding water distribution from the Río Bravo basin, with Mexico committing to release 249,163 million cubic meters of water to the US starting the week of December 15. This understanding comes after escalating tensions, including a public accusation from former President Trump alleging a violation of the 1944 Water Treaty and a warning of impending tariffs.
The agreed-upon volume, while exceeding the 246 million cubic meters promptly demanded by Trump, falls substantially short of the over 986 million cubic meters he claims Mexico owes under the treaty. The 1944 Water Treaty outlines a system of mutual water deliveries, with the US obligated to deliver its share annually and Mexico allowed to fulfill its obligations over five-year periods – the last of which concluded in October 2025.
The situation escalated earlier this week when Trump, via his Truth Social network, accused Mexico of treaty violations and threatened a 5% tariff on mexican goods if the water wasn’t delivered promptly. This prompted swift negotiations resulting in the current agreement.
In a joint statement, both governments acknowledged reaching an understanding on water management for both the current cycle and the previous cycle’s deficit, emphasizing “the critical importance of water delivery obligations under the Treaty and their impact on our citizens.” They also underscored the need for improved, timely water management.
According to the agreement, Mexico “intends to release 249,163 million cubic meters of water to the United States, with deliveries expected to begin the week of december 15.” Both countries have also begun reviewing actions to ensure compliance with the treaty, including addressing the outstanding deficit from the previous cycle, with a plan to be finalized by January 31, 2026.
A statement released solely by the mexican Ministry of Foreign Affairs asserted that Mexico has not violated the 1944 Water Treaty. The ministry attributed the situation to an “extraordinary and unprecedented drought” impacting both countries,while maintaining that Mexico has consistently made additional deliveries “within the framework of the Treaty,the hydrological availability and the operational and infrastructure limits of the region,without affecting water for human consumption and agricultural production on the border.”
The ministry further stated that Mexico’s actions over the past year demonstrate compliance “in accordance with the real availability of the resource, without affecting the human right to water and food production.”
The agreement was reached after days of intense diplomatic activity. Why did this happen? Former President Trump publicly threatened tariffs on Mexican goods,citing alleged violations of the 1944 Water Treaty. Who was involved? The governments of the United States and Mexico, with former President Trump playing a key role through his public statements. What was agreed upon? Mexico committed to releasing 249,163 million cubic meters of water to the US, beginning December 15, and both nations will work to resolve the previous cycle’s deficit by January 31, 2026.
