A strong currency exports inflation to those nations which do not issue the currency.
Though it's difficult to be confident of anything in the current flux, I am pretty confident of three things:
1) price is set on the margins
2) currencies are the foundation of every economy
3) the financial forecasts issued to calm the public do not reflect operative geopolitical goals.
Every national government has "global interests." Governments naturally do whatever they can to boost dynamics favorable to the state and nation, and obstruct or hinder dynamics injurious to the state or nation.
