You are probably referring to
this FT article.
Bloomberg had a longer and fuller article on this subject. Same difference though.
A great thinker and sage predicted this years ago.
Ah yes, that sage.
Well, we all know where the sage goes! (With the onions of course!

)
We could quote articles back and forth until the cows toddle back to the barn, but only time will tell whether some impecunious hack at City-AM, Bloomberg, or the FT is right or if the gloom and doom-sayers like Peter Schiff, Ray Dalio, Jim Chanos and Caren Reinhardt - who predict the collapse of the US money system - are to be believed.

What cannot be denied is the ever-growing importance of the Euro. Five years ago, all gas and oil exports from Russia to China were done in Dollars. Today just 30% are dollars and 60% are Euros - the rest in a mixed bag of currencies. Them's those petro-dollars (aka Euro-Dollars) that we kept hearing about. They are all drifting back into the US, looking for value. Hence the absurd US asset-inflation we are seeing right now.
My take on that here -

First houses, then bonds, then stocks, then commodities, then (surprise, surprise!) general inflation.
House prices go through the roof - but the Fed says there is no inflation.
Share prices go through the roof - but the Fed says there is no inflation.
Commodity prices go through the roof - but the Fed says there is no inflation.
Food prices go through the roof - but the Fed says there is no inflation.
In 2007 the Fed said that sub-prime mortgage bundles (CDOs) were stable. Later chairman Ben Bernanke (CNBC interview) admitted that they only said that to keep a lid on the coming disaster.
i.e. they were lying.
MMT (Modern Monetary Theory - or More Money Today! Take your pick!) is a myth and a dangerous one at that. And this government, the BoE and the Fed are wedded to MMT like it was a liferaft. Printing money can only go one way. There is no magic that keeps a lid on an over-supply indefinitely.
London/The City exists on the coattails of the dollar. i.e. Fugazi. Pixidust.
Fiat currencies are not the economy. They are a human construct. A mathematical calculation, like derivatives and synthetic CDOs and MBSs. Fugazi! Pure Fugazi.
And that goes for the Euro and that fancy new Chinese digital wallet, the DCEP, as well.
You write a number. I wite a number. You write a bigger number. So I write an even bigger number. So you write just as big a number. Now we go and find some sucker who will exchange our numbers for something real. One day, he gets some smarts, looks at our numbers and says "Gentlemen, those are just numbers!"
That day is coming fast! And when it does, all this squabbling about Brexit will be irrelevant. Brexit, along with government ineptitude and the lies of central banks, combined with falling productivity and the C19 hysteria will be just another factor in the destruction of the UK economy.
That's the REAL UK economy. Uncle Joe's corner shop and Aunty Floe's B&B. The butcher, the baker, the candlestick maker.
Banking is just rhyming-slang for what them City Boys are really doing.
