The U.S.$ is still the recognized international reserve currency.
Now think about gold backing the U.S. $ again.
Assuming the Chinese hold approx. $2 trillion in U.S.$ and the U.S. holds 8100 Tonnes of gold, the price of gold, just to satisfy the Chinese, would need to be approx. $7,000/ounce.
Assuming there are $40 trillion U.S. in circulation everywhere (China holds 5%?), the price of gold would need to be approx. $138,000/ounce, just to cover the U.S. FIAT in circulation.
Now, assuming that the U.S. total debt, including those destructive dirivatives, equals $400 trillion, the value of gold would need to be $1,380,000/ounce.
At that price, the U.S. would need to sell only 40 tonnes of gold to the Chinese to buy back their $'s.
Therefore, if the price of gold is $1 million U.S./ounce, China could settle their U.S. holdings for approx 56 tonnes of U.S. gold.
Without destroying the FIAT currencies of the world, something of this magnitude needs to be considered, imo.
I'm just a simple country bumkin and have no idea what this would do to the rest of the world, but something needs to happen and its time to start thinking alternatives, imo.
Good Luck to all!
