Of course, a strengthening of the oil currencies (including not only the Gulf States, but also other Middle East countries and Russia) would not turn around the US trade balance overnight. But oil countries do account for a large share of the world’s trade surpluses, and a weaker dollar would help promote US exports to some degree, even in the short run.
当然，加强石油货币（不仅包括海湾地区国家，而且也包括其他中东国家和俄罗斯）不会使美国的贸易收支一夜逆转。但是石油国家确实占世界贸易顺差相当大的份额，并且即使在短期内，弱势美元都可以在一定程度上帮助促进美国的出口。
