There has been little doubt that the weak US dollar contributed to some spectacular peaks in commodity prices.  Last summer's historic highs for soy and corn stunned most of us.  Although the flooding played a part, the gains were buoyed by the declining dollar.

Fast forward to December of 2008 and we saw sanity return as panicked investors turned to the greenback for safety.  

As the economic crisis continues, and the world has had a chance to move from panic mode  to more thoughtful investing, worry about the strength of the US dollar again weighs on the markets.  Fed Chief Ben Bernanke, in a historic move, pledged to purchase a trillion dollars of treasury debt sending the dollar downward.  

Today, commodities we watch closely, corn and soy, are showing remarkable strength despite no other fundamental reason other than the dollar.
