Finance Ministers from the G20 leading economies have agreed reforms of the International Monetary Fund, giving major developing nations more say. At a meeting in South Korea, they agreed a shift of about 6% of the votes in the IMF towards some of the fast-growing developing countries. Those nations will also have more seats on the IMF's Board, while Western Europe will lose two seats. But the US will retain the veto it has over key decisions.Such decisions require an 85% vote – Washington holds 17% under the IMF's weighted voting system.The Ministers also agreed to refrain from competitive devaluation of their currencies and move towards more market-determined currency systems.
