We have been bullish on the U.S. dollar. We also noted that the strong dollar would become a problem for commodities, as a headwind to U.S. exports, if exceeding 102-103, which has occurred. The currency exchange rate gains weigh on U.S. exports above that level. The dollar index has recently bested 108. For historical perspective the dollar index hit 164 as the Fed killed inflation in the 1980s. The agriculture economy would be dead by then.
