What's important here is that maybe a slowing U.S. economy directly translates into a lower dollar. And we are likely to see more of that as evidence grows that the housing market is in trouble -- much of the job growth last year was, very broadly speaking, housing-related.

Every day, foreigners need to acquire more than $2 billion in U.S. dollar denominated assets -- soon $3 billion -- just to keep the dollar from falling. This can be done through the purchases of U.S. bonds, or by buying assets outright.

Overall, I don't see much structural change, and don't see how the dollar can get much relief from these numbers.
