Reserves are also clearly important for countries that produce only a few goods – especially commodity producers – and thus face big and unpredictable swings in world market prices. Dependency on coffee or cocoa exports requires a build-up of precautionary reserves.
外汇储备显然对只生产少数商品的国家甚为重要-特别是日用品生产国-因为他们要面对世界市场价格不可预测的大幅波动。对咖啡和可可出口的依赖需要有预防性的外汇储备。但这并不适用于中国、日本和印度，这些国家的出口产品是多样化的。
