United States Backs Argentina Infrastructure with Seven Billion Dollars to Secure Critical Minerals

Buenos Aires, Friday, 25 September 2026.
The United States and Argentina launched the seven billion dollar Andes-Atlantic Corridor to build vital transport and energy networks, securing Western access to South American lithium and copper reserves.

Launch of the Andes-Atlantic Corridor and Strategic Objectives

On September 23, 2026, the United States and Argentina officially launched the Andes-Atlantic Corridor, a bilateral initiative backed by up to $7 billion in financing from the Export-Import Bank of the United States (EXIM) [1][2]. Announced in New York on the margins of the United Nations General Assembly by U.S. Deputy Secretary of State Christopher Landau and Argentine Foreign Minister Pablo Quirno, the project aims to link Argentina’s mineral-rich northwest and Vaca Muerta energy basin directly to Atlantic ports [3][5]. This strategic infrastructure corridor is designed to accelerate the export of critical minerals such as lithium and copper to Western markets, thereby reducing dependence on Chinese critical mineral processing and derisking investments in South American clean energy infrastructure [1][7].

Argentina possesses approximately 12% of global lithium reserves, with primary operations located in the Salta and Jujuy provinces, making the logistics upgrade a priority for Western supply chains [1][5]. Currently, logistics in the Andes rely heavily on trucking, but the corridor aims to resolve bottlenecks by replacing long-haul mountain trucking with rail transport and reliable grid power [1][5]. For corporate executives and policymakers, this move signals a major effort to secure supply chains, as EXIM’s financing rules explicitly exclude China-controlled projects and tie loan amounts to the percentage of output destined for U.S. manufacturers under signed offtake agreements [1][5].

Infrastructure Scope and Financing Mechanisms

The initiative facilitates public and private investment across transportation, energy, minerals, and digital infrastructure sectors [2]. A central element is the “US-Argentina Build the Future Framework,” which provides for financing of up to $7 billion by 2027 for projects aimed at expanding infrastructure and productive capacity [3]. Of the total financing, a significant portion is allocated to energy exports; specifically, $6 billion will go to the Argentina LNG project, a venture spearheaded by YPF alongside ENI and XRG [4][6]. This allocation represents approximately 85.714 percent of the total EXIM backing, highlighting the dual focus on both critical minerals and energy security [4][6].

To attract this capital, Argentina has strengthened its legal and regulatory framework through the Incentive Regime for Large Investments (RIGI), which offers tax, customs, and foreign exchange stability for qualifying investments starting at $200 million [2][6]. The Argentine State will not incur public debt for these works, as financing will be provided by EXIM and the U.S. International Development Finance Corporation (DFC) via loans and guarantees to U.S. companies and suppliers [6][7]. This structure shifts credit risk onto U.S. public funds while allowing companies operating in Argentina to use the financing to buy equipment from U.S. manufacturers over the next two years [2][6].

Implementation Timeline and Future Delegations

Following the launch, a U.S. delegation comprising the State Department, DFC, and EXIM is scheduled to visit Buenos Aires, Jujuy, and Salta in October 2026 to identify transactions [1][5]. This visit will be followed by roadshows for U.S. companies scheduled for December 2026, marking the transition from policy agreements to the implementation phase of the Andes-Atlantic Corridor [1][5]. While the bilateral deal was announced in September 2026, Argentina’s Congress has yet to ratify the critical minerals agreement signed in February 2026, which remains a necessary legislative step to solidify the proposed economic cooperation [2][7].

The corridor is the first Partnership for Global Infrastructure and Investment (PGII) corridor in the Western Hemisphere, aiming to modernize railroads, waterways, ports, pipelines, and electrical transmission [3][5]. As the U.S. and Argentina transition to constructing mines, processing plants, and transport infrastructure, companies with Argentine exposure are encouraged to engage ahead of the October delegation rather than wait for final term sheets [1][5]. This timeline underscores the urgency to secure lithium, copper, oil, and natural gas supply chains amidst global geopolitical tensions [3][7].
