Inter-American Development Bank - IDB
  
The Inter-American Development Bank (IDB, fwiw) is an international lending organization—the largest source of funds for development in Latin American and Caribbean countries.
The IDB lends to governments, and is also owned by them (48 of them). Countries like Argentina, Brazil, Chile, and Colombia are all borrowing from the IDB as member owners, while non-borrowing countries include Canada, France, Japan, Norway, the UK, and the U.S., to name a handful.
The Latin America and Caribbean countries make up just over half of shareholding power, giving the borrowers more power than the non-borrowers as a whole. IDB loans go towards developing things...lots of things, including economic integration, productivity, innovation, inequality, early childhood development, and social exclusion.
