Arnold & Porter Advises AIIB on $160 Million Climate Infrastructure Facility in Brazil

Arnold & Porter recently represented the Asian Infrastructure Investment Bank (AIIB) on its $160 million seven-year on-lending facility with BTG Pactual to support climate infrastructure development in Brazil. The deal closed on July 12, 2025.

As AIIB’s largest private-sector deal in Brazil to date, the facility establishes a new partnership between the multilateral development bank and one of Latin America’s premier investment banks. The arrangement will allow BTG Pactual, the largest investment bank in Latin America, to expand its sustainable infrastructure financing capabilities across Brazil.

This transaction aligns with AIIB’s strategic objectives of increasing climate-focused investments to comprise 50% of its portfolio by 2025 and enhancing private sector engagement in developing economies. The deal also strengthens AIIB’s Latin American operations and reflects its strategy of partnering with prominent regional financial institutions.

The Arnold & Porter team was led by partner Chris Willott and included partner Marc Isaacs in London and associates Noel Abdala-Arata and Valentina Garzon.
