The dollar moves up, commodities go down. The dollar weakens, commodity prices move up. This inverse relationship is obvious as items priced in dollars become more attractive when the dollar softens. But it is concerning when the relationship dictates price movement to the degree that it seems to these days.
Remember when the dollar was strong? Some commodities still managed to rally back then, because they did it on their own merits. Can markets focus upon their own fundamentals, or are they subject to following the flow of investor money as it chases the dollar?
