. Established in 1959, the IDB supports Latin American and Caribbean economic, social, and institutional development and regional integration by lending to governments and sub-national agencies, developing new financial tools, creating enabling conditions for private-sector-led growth, convening and aligning countries around common interests, and bridging the region with the rest of the world.
The IDB also provides extensive technical assistance to its borrowing member countries. It works across a range of sectors, including infrastructure, health, education, energy, citizen security, environmental sustainability, trade, transportation, housing, and small businesses.
It works in conjunction with IDB Invest, which pursues development by supporting the region's private sector through lending, mobilization, and advisory services. IDB Lab is the Bank's entrepreneurial innovation and venture-capital arm.
History
At the First
Pan-American Conference in 1890, the idea of a development institution for Latin America was first suggested during the earliest efforts to create an inter-American system. The IDB became a reality under an initiative proposed by President

Operations

The IDB is one of the largest multilateral sources of financing for the Latin America and the Caribbean region.
The IDB provides loans to borrowing member countries at standard
commercial rates of interest, and has ''
preferred creditor'' status, meaning that borrowers will repay loans to the IDB before repaying other obligations to other lenders such as

The IDB has four official languages: English, Spanish, Portuguese and French. Its official names in the other three languages are as follows:
Governance
The IDB is governed by its Board of Governors, composed of representatives of the Bank's 48 member countries. The Governors are usually finance ministers or other senior economic officials. The Board gathers at an Annual Meeting in March or April to review the Bank’s operations and make major policy decisions.

that borrow from the IDB are the
majority shareholders, and therefore control the majority of the decision-making bodies of the Bank. Each member's
voting power is determined by its shareholding: its subscription to the Bank's ordinary capital. The United States holds 30 percent of the Bank's shares, while the countries of Latin America and the Caribbean combined hold 50.02 percent, with another 20% held by member countries in Europe and Asia. This arrangement is unique in that the developing member countries, as a group, are the majority shareholders. Though this arrangement was first viewed as risky, it is believed by some that strict peer pressure prevents the borrowers from
defaulting, even when under severe economic pressure.
Presidents

Mission
The Bank's mission and slogan is "improving lives." At its 2024 Annual Meetings, the IDB Board approved a new institutional strategy, predicated on boosting the impact and scale of the Bank's development work through reforms. The strategy's three core objectives are reducing poverty and inequality, addressing climate change, and bolstering sustainable growth. The Board also approved a doubling of IDB Invest's capital and a new business model, "originate to share," that aims to significantly increase its ability to mobilize private capital for development projects. IDB Lab reforms and a replenishment were also approved. The three major approvals have been dubbed "IDBImpact+" by the Bank.
Financial resources

, therefore functions as a guarantee for the
bonds that the IDB sells. This arrangement ensures that the IDB maintains a triple-A
credit rating, and as a result can make loans to its borrowing member countries at rates of interest similar to those that commercial banks charge their largest corporate borrowers. At the same time, the 22 non-borrowing countries are only putting up guarantees – not actual funds – so their support of the IDB's lending operations has a minimal impact on their national budgets.
The funds that the IDB lends are raised by selling bonds to

s at standard commercial rates of interest. The bonds are backed by (a) the sum of the capital subscriptions actually paid in by the Bank's 48 member countries, plus (b) the sum of the callable capital subscriptions pledged by the Bank's 22 non-borrowing member countries. Together these constitute the Bank's ''ordinary capital'', some $101 billion. Of this amount, 4.3 percent is paid in, while the remaining 95.7 percent is callable.
According to the IDB's 2023 Annual Report, the Bank approved 92 sovereign-guaranteed loan projects for $12.7 billion in total financing that year. According to IDB Invest, it had a "record year" in 2023, with total activity surpassing $10 billion, including $5.3 billion in mobilized resources from private investors. In 2025, IDB President Ilan Goldfajn announced the intention to increase financing capacity by an additional $130 billion over a decade.
According to the IDB's own measurements for 2024, 76% of IDB loan approvals, 94% of IDB Invest commitments and 96% of IDB Lab approvals supported sustainable economic growth in Latin America and the Caribbean.
Country status
The Bank is owned by 48 sovereign states, which are its shareholders and members. Only the 26 borrowing countries are able to receive loans.
Latest capital increases
On July 21, 2010, the Board of Governors agreed to increase the Bank's ordinary capital by $70 billion, the largest expansion of resources in the Bank's history, and to provide an unprecedented package of financial support to Haiti. The agreement also includes a replenishment of the Fund for Special Operations, which finances operations in the region's poorest nations.
A recapitalization and new, pro-mobilization business model for IDB Invest was approved in 2024.
Priority areas
According to the Bank's latest institutional strategy, it works in seven focus areas: 1. biodiversity, natural capital, and climate action; 2. gender equality and inclusion of diverse population groups; 3. institutional capacity, rule of law, and citizen security; 4. social protection and human capital development; 5. sustainable, resilient, and inclusive infrastructure; 6. productive development and innovation through the private sector; 7. regional integration.
Criticisms

democratic reform in the region". The BIC cites
environmental and social damage funded by the IDB as adversely impacting
local economies, contrary to IDB's stated goal of fostering social and economic prosperity.
Poverty reduction
Governments of developing countries are not equipped to reduce poverty due to heavy responsibility to build and maintain infrastructure, as well as meet payroll and debt obligations. Tax revenue is often weak or non-existent. Poverty reduction depends largely on business investment in global markets to create sustainable jobs for economic empowerment of individuals. International companies need funding, and difficulty lies on the inability of the investment banks to overcome regulatory obstacles.
Small business entities are largely responsible for improving lives, as they play an inherent role in raising the socio-economic status of families, making it possible to combat poverty in the long range, as employed heads of household are in better positions to finance the education of children for a better future. Hence, empowering institutions, such as, the
