不论这一观点是对是错，有一点是相当明确的：随着美联储与其他各国央行的货币紧缩周期政策背道而驰，加上各大评级机构纷纷考虑调低美国的信用评级，美元的购买力相对于美国的贸易伙伴来说已经下降到了前所未有的低点。
Whether or not the critics are right, one thing is clear: with the Fed lagging other global central banks in the monetary-tightening cycle, and with rating agencies contemplating a downgrade of America’s credit score, the US dollar’s purchasing power has sunk to an all-time low against the currencies of America’s trading partners.
