The United Kingdom is moving to acquire all remaining non-regional unsubscribed shares in IDB Invest’s capital increase, resulting in an eight-fold increase in its shareholding. This strategic move is designed to complete the capital increase process and expand IDB Invest's role as the premier development partner for the private sector in Latin America and the Caribbean. The transaction will also fully implement IDB Invest's Originate-to-share business model.

IDB Group President Ilan Goldfajn stated that the commitment from the United Kingdom will amplify support for private-sector-led development in the region, delivering more scale and impact. James Scriven, Chief Executive Officer of IDB Invest, noted that the UK's decision underscores confidence in the institution's mission and strategic direction. He added that completing the capital increase strengthens the ability to mobilize private capital at scale and deepen development impact.

Jenny Chapman, the UK’s Minister of State for International Development and Africa, emphasized that governments cannot work alone in pursuing economic, social, and environmental development. She highlighted that boosting investment in IDB Invest should unlock larger flows of private finance, fostering growth and economic opportunities in both the region and the UK.

The UK's support reflects strong shareholder backing that underpinned Standard & Poor’s recent decision to upgrade IDB Invest's credit rating to 'AAA', the highest possible, from 'AA+'. The upgrade is attributed to the institution's robust governance and the success of its business model, which has expanded its ability to mobilize private capital for development.

IDB Invest, a member of the IDB Group, is a multilateral development bank focused on promoting economic development in Latin America and the Caribbean through the private sector. It finances sustainable companies and projects to achieve financial results and maximize economic, social, and environmental development. The institution manages a portfolio of $22 billion in assets under management and serves more than 440 clients across 25 countries.

IDB Invest, the private-sector arm of the Inter-American Development Bank Group, has achieved the highest possible 'AAA' credit rating from S&P Global Ratings. The upgrade from 'AA+' strengthens the institution's ability to support private-sector-led development across Latin America and the Caribbean. This rating reflects IDB Invest's robust governance and its successful transition to an originate-to-share business model, which has expanded its ability to mobilize private capital.

The new rating follows the successful completion of IDB Invest's $3.5 billion capital increase process. Combined with the originate-to-share model, the additional capital is expected to increase IDB Invest's financing and mobilization capacity from about $13 billion today to roughly $22 billion annually over the next decade. This expansion will support more projects and create economic opportunities in the region.

In 2025, IDB Invest reached a record $13.1 billion in financing, which included $7.7 billion in mobilization. Since 2016, the institution has channeled more than $75 billion to Latin America and the Caribbean, supporting over 700 projects in sectors such as infrastructure, energy, trade financing, health, and productive development.

IDB Group President Ilan Goldfajn stated that the upgrade reflects the transformation of IDB Invest and the strong support of its shareholders. He noted that the rating expands the institution's capacity to support businesses and boost private-sector-led development across the region. IDB Invest CEO James Scriven described the AAA rating as a historic moment that validates the institution's transformation, business model, and successful capital increase process.
