Fiat currencies are hanging on by a thread and the federal reserve’s persistent efforts to short commodities through JP Morgan will cease to work soon. The expansion of M1 from 2008 to 2016 is around 400% which means the amount of US dollars in circulation has gone up 4 times since 2008; all of this new money was printed and has NO backing.
A run on the US Dollar and all other fiat currencies can be precipitated if every person living in London right now just bought 38 ounces of physical silver and this would send the US Dollar into a tailspin and uncontrolled depreciation.
