An important corollary for commodity-producing developing countries is that industrial metal prices, which really are leading indicators of economic activity, may well increase after an oil-price collapse. In 1986-87, for example, metal prices doubled a year after oil prices fell by half.
对生产大宗商品的发展中国家来说，一个重要推论是工业金属价格——这才真正是经济活动的先行指标——极有可能在油价崩盘后上涨。比如，1986—1987年，金属价格在油价腰斩后的一年里实现翻番。
