The dollar rallied to a 1-year high against the world's currencies today, following Treasury's decision to seize control of Fannie Mae and Freddie Mac. After an early hiccup, the greenback advanced to $1.41 against the euro while also climbing against the yen, the pound, and the Swiss franc. While the Fannie-Freddie bailout reassured investors, reports that Asian banks might buy out Lehman Brothers also helped to push up the dollar. (More US dollar stories.)
