The congresswoman's proposal Monica De La Cruz to impose tariffs on México for an alleged breach of Water Treaty of 1944 has set off alarm bells in the international trade ecosystem. The initiative, presented to the Congreso de Estados Unidos, threatens to add a new layer of complexity to the already delicate trade relations in Norteamérica, with potential repercussions for Spanish companies operating under the umbrella of T-MEC (USMCA).

This protectionist measure, which arises in a context of water tensions at the border, elevates a dispute over natural resources to the realm of foreign trade. For Spanish executives with operations in the region, this news represents a geopolitical risk focus which must be closely monitored.

The origin of the conflict: The Water Treaty of 1944

The treaty in question regulates the distribution of river waters Colorado, Tijuana y Río Grande (known as Río Bravo en México) between both countries. According to the proposal of De La Cruz, México It would not be fulfilling its water delivery obligations, which would justify a strong response in the form of trade sanctions.

International law experts consulted by Empresa Exterior They point out that "using tariffs as a pressure tactic over a matter that is not strictly commercial sets a dangerous precedent, as it opens the door to..." instrumentalization of trade policy to resolve disputes of any other kind."

Implications for the USMCA and Spanish companies

The main concern for Spanish businesses is the impact these tariffs could have on the stability of the T-MEC. México It has established itself as a strategic platform for Spanish multinationals, especially in sectors such as automotive, aerospace and manufacturing, who take advantage of the treaty to access the US market.

A tariff escalation could lead to:

• Supply chain disruption: Components and products manufactured in México Spanish subsidiaries would see their entry costs increase in EE.UU.
• Uncertainty for nearshoring: Strategies to relocate production to be closer to the North American market could be compromised by regulatory instability.
• Review of investment plans: The profitability of current and future investments in México, designed to serve the US market, would be called into question.
