I think that's a pretty misleading TLDR (as it suggests nothing will change which isn't at all what the article claims); The title is a better summary of the message.
The article is about as meaningful as you'd expect one that suggested "Democracy's primacy looks unsustainable", and is full of examples of things that don't mean anything.

Sucking capital from emerging markets is not an attribute of a currency that's fading, so much as one whose primacy is in fact increasing after a lull...

There used to be a great quote on Wikipedia's page about the Economist pointing out it's largely written by early-20s Oxford graduates. If they think America's use of its financial clout is increasing, it would seem their view of history starts circa 2001.

Oh look, even the article suggests the title is wrong!
