The shares of the major reserve currencies were stable, with the dollar accounting for 62% of foreign-exchange reserves in 2009 and the euro 27%. Any major changes came not from deliberate decisions by central banks to reallocate reserves, but rather from the simple arithmetic of changing exchange rates: a stronger dollar raised the dollar’s share in total global reserves, while a weaker dollar reduced it.
到目前为止，本轮全球金融危机尚未对外汇市场发生显著影响，这在历史上相当罕见。各大储备货币的份额基本保持稳定，2009年，美元占全球外汇储备的62%，欧元占27%。凡有较大的变动，并不是由于各国央行出台了什么重新配置外汇储备的措施，而是源于汇率波动带来的算术上的变化：美元走强提升其在全球储备中的份额，走弱则减低该份额。
