Most money in the world today exists as 1s and 0s.
It's value is, as it is perceived to be, the value of the asset it exists in.
A dollar is a dollar and is worth so many euros.
A euro is a euro and is worth so many yen.
A yen is a yen and is worth so much gold... and on and on and on.
The dollar should be... right now... in the tank. Inflation should by running ten times what it is here.
The only reason I can think of for this is... it's perceived value in the eyes of the world is still higher than all the rest.
As long as that continues... the dance goes on.
Once that stops... then the earth begins to move... the dollar holds no value, then other things begin to hold less value (see China with their pegged to the dollar yeun)
All other currencies head down as their perceived values also decline. Try as they might, no one has managed to become (like the dollar has been, and remains yet today, the last safe refuge). Not the yen, or the euro, or any other. Each has their own issues...
Gold goes through the roof (2.5k or higher), as the only real asset. Other hard commodities join in the climb, silver of course, platinum, copper, and others.
As in late 2008 the world will hold it's breath and wait... and the politicians and financial bureaucrats will sing and dance... and eventually the market begins again to perceive value in things other than hard assets... and the game begins again... as it must.
1s, 0s... too many 1s and 0s
