When world trade collapsed, so did the need for US dollars, which is what the world uses to transact business. The data looks like world trade is finding a bottom and maybe even recovering somewhat. That means there will be the need for more dollars. And since everybody and their mother are short the dollar, there could be a vicious snap-back rally. I am still bearish the US dollar (and the yen and the euro and the pound) over the long term, but there is the potential for a real rally here.
