US_Dollar_crises

This is the 2nd largest quarterly gain for the US dollar since 1970 and the quarter isn't even over!! This chart really puts into perspective the magnitude of the current US dollar rally. The first Gulf War, The Asian Currency Crisis, and the Lehman Brothers bankruptcy pale in comparison to the current bout of dollar strength. The question is: Which crisis is this one? The final chapters of which remain unwritten.
