The list of such currency movements – which so far has included the euro's 25% fall against the dollar, a record low for the Mexican peso, and disorderly depreciations of the Brazilian real and other emerging-economy currencies – is getting longer by the day. Even healthy economies like South Korea are keen to weaken their currencies, leaving the US alone in its willingness to tolerate significant currency appreciation.
此外，市场力量在协调全球经济差异中所发挥的作用越来越大，导致汇率呈大幅波动态势。类似的货币走势表——到目前为止包括欧元兑美元下跌25%、墨西哥比索创历史新低、巴西雷亚尔和其他新兴市场货币无序贬值—— 每天都会增加新的事例。就连韩国等健康经济体也急于让货币贬值，宁愿忍受货币大幅升值的仅美国一家而已。
