In the US, the inflation rate has also been depressed by the rise in the value of the dollar relative to the euro and other currencies, which has caused import prices to decline. This, too, is a “level effect," implying that the inflation rate will rise once the dollar's exchange rate stops appreciating.
在美国，美元相对欧元和其他货币升值也是抑制通胀率的一个原因，因为这压低了进口价格。这也是一个“水平效应”，意味着只要美元汇率停止升值，通胀率就会上来。
