The countless analysts who keep preaching that the dollar will collapse have been singing the same song since 1971. They NEVER look outside the USA and simply preach how the US debt (over $20 trillion) will result in hyperinflation and the end of the US economy. They ignore the fact that the US is a tiny fraction of global sovereign debt. They also ignore the fact that there is already $17 trillion in negative yielding euro bonds out there.
I have been warning that the USA will be the last to fall. The stress on the world monetary system will be seen outside the USA. We have seen defaults on foreign denominated debt by now in Lebanon. This is just the beginning. We are looking at a contagion spreading in 2020 on a global scale.
