The IMF's mandate and governance have evolved along with changes in the global economy, allowing the organization to retain a central role within the international financial architecture. The diagram below provides a stylized view of the IMF's current governance structure.

Board of Governors

The Board of Governors is the highest decision-making body of the IMF. It consists of one governor and one alternate governor for each member country. The governor is appointed by the member country and is usually the minister of finance or the head of the central bank.

While the Board of Governors has delegated most of its powers to the IMF's Executive Board, it retains the right to approve quota increases, special drawing right (SDR) allocations, the admittance of new members, compulsory withdrawal of members, and amendments to the Articles of Agreement and By-Laws.

The Board of Governors also elects or appoints executive directors and is the ultimate arbiter on issues related to the interpretation of the IMF's Articles of Agreement. Voting by the Board of Governors usually takes place by mail-in ballot.

The Boards of Governors of the IMF and the World Bank Group normally meet once a year, during the  IMF-World Bank Spring and Annual Meetings, to discuss the work of their respective institutions. The Meetings, which take place in September or October, have customarily been held in Washington for two consecutive years and in another member country in the third year.

The Annual Meetings usually include two days of plenary sessions, during which Governors consult with one another and present their countries' views on current issues in international economics and finance. During the Meetings, the Boards of Governors also make decisions on how current international monetary issues should be addressed and approve corresponding resolutions.

The Annual Meetings are chaired by a Governor of the World Bank and the IMF, with the chairmanship rotating among the membership each year. Every two years, at the time of the Annual Meetings, the Governors of the Bank and the Fund  elect Executive Directors to their respective Executive Boards.

Ministerial Committees

The IMF Board of Governors is advised by two ministerial committees, the International Monetary and Financial Committee (IMFC) and the Development Committee.

The IMFC has 24 members, drawn from the pool of 186 governors. Its structure mirrors that of the Executive Board and its 24 constituencies. As such, the IMFC represents all the member countries of the Fund.

The IMFC meets twice a year, during the Spring and Annual Meetings. The Committee discusses matters of common concern affecting the global economy and also advises the IMF on the direction its work. At the end of the Meetings, the Committee issues a joint communiqué summarizing its views. These communiqués provide guidance for the IMF's work program during the six months leading up to the next Spring or Annual Meetings. There is no formal voting at the IMFC, which operates by consensus.

The Development Committee is a joint committee, tasked with advising the Boards of Governors of the IMF and the World Bank on issues related to economic development in emerging and developing countries. The committee has 24 members (usually ministers of finance or development). It represents the full membership of the IMF and the World Bank and mainly serves as a forum for building intergovernmental consensus on critical development issues.

The Executive Board

The IMF's 24-member Executive Board takes care of the daily business of the IMF. Together, these 24 board members represent all 186 countries. Large economies, such as the United States and China, have their own seat at the table but most countries are grouped in constituencies representing 4 or more countries. The largest constituency includes 24 countries.

The Board discusses everything from the IMF staff's annual health checks of member countries' economies to economic policy issues relevant to the global economy. The board normally makes decisions based on consensus but sometimes formal votes are taken. At the end of most formal discussions, the Board issues what is known as a summing up, which summarizes its views. Informal discussions may be held to discuss complex policy issues still at a preliminary stage.

Governance Reform

Important progress was made in the reform of the Fund's governance in 2006-08, including the initiation of a process to realign members' voting power (see Country Representation). However, enhancing the Fund's legitimacy and effectiveness must also deal with the question of whether the significant changes since the establishment of the Fund require reform of the institutional framework through which members' voting power is actually exercised. Among other things, this requires careful consideration of the respective roles and responsibilities of the Board of Governors, the IMFC, the Executive Board, and IMF management.

Managing Director Dominique Strauss-Kahn appointed in September 2008 a committee of eminent persons to assess the adequacy of the IMF's current framework for decision making and advise on any modifications that might enable the institution to fulfill its global mandate more effectively. The eight-person committee, chaired by Trevor Manuel, Minister of Finance of South Africa, reported its findings in March 2009.
