In reality, while currency movements can have a significant impact on inflation in other countries, dollar movements have rarely had a meaningful or durable impact on prices in the US. The difference, of course, lies in the US dollar’s dominant role in the invoicing of international trade: prices are set in dollars.
在现实中，其他国家的货币波动可能给它们的通胀造成重大影响，但美元波动很少对美国物价造成有意义的或持久的影响。当然，这当中的差别原因在于美元是国际贸易的主要结算货币：价格都是用美元定的。
