Just as the dollar is often the unit of account in debt contracts, even when neither the borrower nor the lender is a US entity, the dollar’s share in invoicing for international trade is around 4.5 times America’s share of world imports, and three times its share of world exports. The prices of some 93% of US imports are set in dollars.
正因美元常常作为债务合同记账单位，即使是借贷双方都不是美国实体的情况下也是如此，所以国际贸易结算的美元占比高达美国的世界进口占比的4.5倍和世界出口占比的三倍左右。93%左右的美国进口品用美元计价。
