The system has been fine tuned a number of times since 1973. The Jamaica Agreement of 1976, signed by IMF members, formalized the floating rate system that replaced the Bretton Woods System. Floating rates were declared acceptable and IMF members were permitted to trade in the foreign exchange(forex) markets to balance out speculative fluctuations of their currencies that were unwarranted. Gold was abandoned as a reserve asset. Total IMF quotas that member countries contributed to the organization were increased to $41 billion. They have since been increased to more than $180 billion.　　
　　自1973年以來(lái)，該體系在多個(gè)時(shí)期協(xié)調(diào)運(yùn)轉(zhuǎn)。1976年的雅買加協(xié)議，由國(guó)際貨幣基金組織成員簽署，使浮動(dòng)匯率體系正式取代布雷頓森林體系。浮動(dòng)匯率被正式接受，國(guó)際貨幣基金組織成員被允許在外匯市場(chǎng)上交易，以抵消其無(wú)擔(dān)保貨幣的投機(jī)性浮動(dòng)。黃金不再作為儲(chǔ)備資產(chǎn)，成員國(guó)向國(guó)際貨幣基金組織繳納的總配額增加到410億美元。從那時(shí)起，國(guó)際貨幣基金組織份額一直增加到1,800多億美元。
