Many argue that IMF vote-shares (and the amounts countries are required to put into the fund's kitty) should reflect countries' relative economic heft. At the moment, however, that is far from being the case. Taken together, the economies of the European Union countries amount to just under 24% of the global economy.
The economies of Brazil, Russia, India, China and South Africa together make up about 21% of world GDP. But the European countries have 32% of the votes in the IMF, while the BRICS have 11%. No wonder the BRICS' representatives to the fund issued a rare joint statement deploring Europe's lock on the top job at the IMF, which is made possible in part by the fact that Europe and America between them have nearly 50%of the votes in the IMF's board.
Proportionately, sub-Saharan Africa, (excluding South Africa) is the most over-represented region, with 3.1% of the vote but a mere 1.35% of the world economy.
