.5% interest rate slowly lowers dollar value

Whenever the interest rate is dropped by the Fed it creates less foreign interest in some U.S investments because of a potentially lower return between their currency and ours. This tends to create a lower U.S. dollar value.

Also, as this economic crash deepened many foreign currencies were hurt and people ran to the dollar for stability. However, now many of those foreign currencies have finished tanking and so those people who ran to the dollar for security are returning to their home currencies since most home foreign currencies have somewhat stabilized. as a result of both of these factors the dollar likely will slide downward for a little bit. It's hard to say how long this will be.

The good news in this if there is any in this is that American manufacturers might be able to sell more easily to foreign countries since the exchange rate might get better for foreign sales now for awhile.
