Wallerstein is right: central banks--including the Federal Reserve-- are losing control of the value of their currencies, their role in the global economy and the social discontent that arises as central bank policies negatively impact average citizens.
It's by no means guaranteed that central banks will be able to maintain their death-grip on interest rates, either.
Eight years after the crisis of 2008-09, central banks are still injecting $200 billion a month into the global financial system to keep it from imploding. The returns on their "investment" is diminishing rapidly, and they're losing control of everything that matters.
I think this is a good summary of OP article ^.
$200 billion a month requirements for the global financial system to avoid collapse seems unsustainble to me.
Which could infer the question what happens when such "quantitative easing" programs are no longer tenable?
There was another article I read which claimed banks profit from those QE programs.
There could be some conflicting info, present.
