South American countries seem to have started new currency among them. It means US dollar would lose it’s power a little over those countries. Many countries are worried about the international currency because American economy is still weak and vague for it’s recovery.

But…what if US dollar loses the international power ?

Euro ? Yen ? or Chinese Gen ?

It would be a big confusion if the US dollar falls into chaos.

The Japanese always change JP Yen to US dollars when they go traveling. What currency would be replaceable after US dollar ?

Many say with hopeful expectation that the US dollar will never lose its power at least 10 or 20 year more.  If so, the world structure doesn’t change soon. But if that change really happens, there will be a big change in the world economy, and world politics.

Probably the Japanese don’t understand how they are faced with very important time for the world, including Japan.
