DXY has climbed from 100.7 to above 101.1 in two trading days, even as the Fed, ECB and BoJ all turned hawkish for the first time in many years, and even as a weak jobs report knocked it lower a week earlier. The market keeps trading this as a domestic growth and rate story. The real driver is a shared external shock hitting four central banks at once one the market has not fully priced into the dollar’s terms of trade advantage yet. That gap sets up a further move toward 103 to 104 while the Strait stays shut down. The mechanism, the terms of trade math, and the level that would prove me wrong all follow below.
