With the release of ReInvest+, a portal developed to direct enormous volumes of capital, the Inter-American Development Bank (IDB) is adopting a fresh approach to climate finance, from private capital into sustainable initiatives in the Caribbean and Latin America. Unveiled during Brazil’s COP30 presidency, the project seeks to release billions of dollars in climate-related investment by transforming local bank loans into market-ready bureaucratic innovation assets for worldwide investors.
The discrepancy between local initiatives and global investors has been one of the main obstacles in climate funding for years. Many projects in the area depend on loans denominated in local currencies, have no ratings, or are judged too dangerous by institutional investors. Launch of ReInvest+ inverts that relationship.
According to the scheme, loans already held by regional banks will be bundled and upgraded into investment-grade items with risk insurance. Once sold, the banks have to invest the profits into new, environmentally friendly projects, thereby establishing a reinvestment cycle to solve problems, including political instability and currency volatility.

The Inter-American Development Bank (IDB) estimates that Latin America and the Caribbean possess up to $500 billion worth of eligible loans that may be used for the Program, part of a multi-trillion-dollar global pool. The model could repurpose idle capital into sustainable agriculture, green infrastructure, and renewable energy. Local banks will be quite important. In addition to providing seasoned loans, they should keep scouting and overseeing next initiatives to make sure financing matches up with national climate goals.
By October 24, the bank had asked commercial and international organizations to provide interest in the program. In the run-up to COP30 participant list, scheduled next year in Brazil, partners will be revealed. Though the starting scale of ReInvest+ has not been revealed, the pilot project is developed with growth in mind. If it succeeds, it may be copied and grown to organize much more money over time.
