The Inter-American Development Bank (IDB) is a multilateral development bank established in 1959 as the main source of development financing for Latin America and the Caribbean. It has 48 member countries: 26 borrowing members in Latin America and the Caribbean and 22 non-borrowing members in Asia, Europe and North America that contribute capital but do not receive IDB financing. The IDB Group comprises three entities: the IDB itself, which works with public sector clients including national, subnational and municipal governments; IDB Invest, which engages the private sector; and IDB Lab, which supports innovative entrepreneurship. IDB provides financial support, technical assistance, research and innovative solutions to address development challenges in its borrowing member countries, guided by its IDBStrategy+ institutional strategy for 2024 to 2030 on sustainable and inclusive development. Its public sector instruments include Ordinary Capital sovereign loans through a Flexible Financing Facility, concessional financing on more favorable blended terms for its most vulnerable member countries (currently Guyana, Honduras and Nicaragua), Partial Credit Guarantees and Political Risk Guarantees under its Flexible Guarantee Instrument to help governments and their entities access private financing on longer maturities, and non-reimbursable grants funded from its own resources or third-party contributions to support technical cooperation. In 2025, the IDB Group delivered approximately USD 35 billion in financing, including nearly USD 20 billion to the public sector across 100 sovereign-guaranteed projects and USD 13 billion through IDB Invest. IDB's work spans 28 named development topic areas, including agriculture, education, energy, financial inclusion, health, transport, urban development and housing, and water, sanitation and solid waste, among others.
