You can thank your newly elected officials for the US dollar falling like a rock. It's a direct result of the trillions of dollars spent by our federal government which they don't have. We can't simply print money and give it away without serious consequencies.
You can expect the dollar to continue to fall until our president has the balls to step up to the podium and say "No more bail out money"! At that time your US dollar will begin to stabilize.
Politics is a nasty game and since all branches of our government is controlled by one party, I wouldn't get my hopes up for things to get better anytime soon.
