Very interestingly last week a never seen before behaviour changed in the currency space.
Every Time there is a scare event like North Korea usually the USD strengthened. And this is happened since the 2 World War until last week.
The other usual refuge currencies (Yen, Swiss Franc, Gold) strengthen.
But the US Dollar weakened and the Chinese Yuan strengthened.
This is really a shift of power from the US to China.
A classic sign of the fall of an empire.
