How Does IDA Work?

IDA is overseen by its 173 shareholder countries, which comprise the Board of Governors. The day-to-day development work of IDA is managed by Bank operational staff, governments, and implementing agencies.

While the World Bank's original lending arm, the International Bank for Reconstruction and Development (IBRD), raises most of its funds on the world’s financial markets, IDA is funded largely by contributions from the governments of its member countries. Donors meet every three years to replenish IDA resources and review its policy framework.

The most recent replenishment of IDA’s resources— the 18th replenishment (IDA18)— was finalized in December 2016, resulting in a record replenishment of $75 billion to finance projects over the three-year period ending June 30, 2020.  Under IDA18, IDA will double resources to address fragility, conflict and violence (more than $14 billion), with an additional $2 billion to support refugees and their host communities. A new $2.5 billion Private Sector Window (PSW), introduced together with the International Finance Corporation (IFC) and Multilateral Investment Guarantee Agency (MIGA), will help mobilize private capital and scale up private sector development in the poorest countries, particularly in fragile situations. The replenishment process typically consists of four formal meetings held over the course of one year. In addition to officials from the now 50+ donor governments (known as “IDA Deputies”), representatives of borrowing member countries are invited to participate to help ensure that IDA’s policy and financing frameworks are responsive to country needs.

Policy papers discussed during the replenishment negotiations are disclosed to the public, and the draft replenishment agreement is posted on the web for public comment prior to the last replenishment meeting. IDA staff also engage with civil society organizations, foundations and think tanks around the world on an ongoing basis.
