IDA (International Development Association)

The International Development Association (IDA) was established in 1960 as part of the World Bank Group to complement the International Bank for Reconstruction and Development (IBRD). While the IBRD lends to middle-income countries on near-market terms, IDA was designed to channel highly concessional finance to low-income countries that cannot afford to borrow commercially.

IDA is headquartered in Washington, D.C., and shares staff and leadership with the IBRD; together they are commonly referred to as "the World Bank." Eligibility for IDA support is based primarily on a country's gross national income per capita and its lack of creditworthiness for IBRD lending. Countries that improve economically can "graduate" from IDA, as China, India (partially), and South Korea have over time.

IDA's resources are replenished roughly every three years through pledges from donor governments, supplemented by repayments from past credits and transfers from the IBRD and IFC. Each cycle is negotiated among donors and borrowers and sets the policy framework and financing envelope for the coming period.

IDA financing supports operations in areas including basic education, primary health, clean water, agriculture, infrastructure, institution-building, and climate adaptation. Instruments include long-maturity credits with extended grace periods, outright grants for countries at high risk of debt distress, and specialized windows such as the Crisis Response Window and the Private Sector Window.

Although IDA is technically a separate legal entity from the United Nations system, it is a UN specialized agency through the World Bank Group's relationship agreement with the UN and frequently coordinates with UN funds and programmes on country-level development work. Decisions are taken by a Board of Governors and a resident Board of Executive Directors, with voting power weighted by contributions, a structure that has drawn ongoing debate about borrower voice and governance reform.
