According to the Wall Street Journal, world demand for US products is boosting profits at US manufacturers.  You would expect that to increase demand for - and the value of - the US Dollar.

But Reuters reports that the dollar is poised to reach an all time low as investors flee low interest rates, threats of a credit downgrade, and rumbles that the USD may lose its position as the world's reserve currency.  Investors seem to be ignoring that the threat to downgrade US Treasury Securities comes from the same people who gave AAA ratings to subprime mortgage securities only three years ago, and that the Euro remains under pressure because of economic problems in Ireland, Greece Spain and Portugal.
