The dollar is the promise, the IOU that the US gives to their creditors and they accept it in good faith that they will be able to repay their debts. 20 Trillion in debt and rising, the bond market is beginning to collapse which will send immediate real shock waves throughout the US economy. The Creditors are loosing faith. There is absolutely no way the US will be able to repay all of their sovereign debts. Their options are to either default or start printing money and both spell doom for the value and reputation of the Dollar. People underestimate the extend to which the supposed US recovery has been based on low interest rates. When rates rise, and they will, we will see whether on not the recovery has been real. I couldn't agree more with your chart, these are very interesting times indeed.
