The International Development Association (IDA) is one of the five institutions of the World Bank Group, established in 1960 to complement the International Bank for Reconstruction and Development (IBRD) by serving countries too poor to borrow on market terms. Its Articles of Agreement entered into force on 24 September 1960, and it is headquartered in Washington, D.C.
IDA provides credits (long-maturity loans with zero or very low interest), grants, and guarantees to eligible low-income countries. Eligibility is determined primarily by Gross National Income per capita against an annually updated operational cutoff, and by a country's lack of creditworthiness for IBRD borrowing. Countries that cross the threshold may "graduate" from IDA, as China, India, and most recently several middle-income states have done, though some remain on transitional "blend" status.
Resources are replenished roughly every three years through pledges from donor governments in a negotiation known as the IDA Replenishment. The replenishment cycle (e.g., IDA20, IDA21) sets the financing envelope and policy commitments — recent cycles have emphasized climate adaptation, fragility/conflict/violence (FCV) settings, human capital, and pandemic preparedness. Since 2018, IDA has also leveraged donor contributions by issuing bonds in capital markets, earning a triple-A credit rating.
IDA is governed by the same Board of Governors and Executive Directors as the IBRD, with voting power weighted by financial subscription. Its president is the President of the World Bank Group. Although technically a UN specialized agency under a 1961 relationship agreement, it operates with substantial autonomy from the General Assembly and ECOSOC.
For MUN and IR researchers, IDA is the principal multilateral channel for concessional development finance and is frequently cited alongside regional equivalents such as the African Development Fund and the Asian Development Fund. It is distinct from the IMF's Poverty Reduction and Growth Trust, which provides balance-of-payments rather than project finance.
Example
In December 2024, donors pledged a record financing package for the IDA21 replenishment to support low-income countries through 2028.
Frequently asked questions
The IBRD lends at near-market rates to creditworthy middle-income countries, while IDA offers concessional credits and grants to the poorest countries that cannot sustainably borrow on IBRD terms.
