So what. Is the USD worth zero? We already have lost 20% of the value of our currency in a year. That is a huge move. Let's look forward.
Second is the options action on the USD Jan 10 Option Chain (expressed through the UUP - USD Bullish ETF). At least one major hedge fund or active market participant has engaged in a bull call spread that will make money as UUP crosses $25.25 or so. Minimal action on the put side of the equation is a bad sign for anyone short the USD.
These positions could be just foolish bets from large accounts dumb money. But sometimes making positions in front of any trend where lots of money is moving in the same direction is the best place to be, smart or dumb.
