Compare it to any other currency market. Canadian, British, Australian...
There are countries that are actually making the US situation worse by losing faith in the currency as well. Russian has dumped more than half it's reserves, and bought out Euros and Pounds instead. It not only flooded the market with more dollars (hooray more devaluation!!) but it's my understanding it strengthened it's main competators and encouraged a small following from other countries.
There's a story I read the other day in a paper that theorised the dollar could be sent to shit if China decided to follow Russia's lead and dump it's dollar reserves before their value goes even lower. Doing that, would pretty much pay-back the US for some of it's more unfriendly foreign policies - and unfortunately China isn't the kind of country you can trust to be an ally in that situation :( If I were you, I'd quickly consider investing in something like Euros, Pounds or Canadian dollars because there are a number of things that could go horribly wrong right now and throw the dollar down even further. There's already scares of a depression.
If anyones got advice on the best way to invest my current dollars, I'm open to ideas. I'm mainly thinking of taking an empty suitcase, buying the plane ticket/gifts/clothes/a nintendo wii, then transporting it all back to Britain that way hoping I don't get stung in customs for a new camera and stuff.
