The conventional wisdom is that no other currency in the world can support the global bond market save the US$ Toilet Paper Money. Therefore, we cannot do without the US$ toilet paper money!
The so-called experts in economics, including the Nobel Laureates are always reciting the mantra of the global central banks led by the FED and the Bank of England (BOE) that the US$ Toilet Paper Money is indispensable to global monetary liquidity because it is the anchor of the global bond market, specially the US Treasury bonds.
Such is the accepted wisdom of the so-called wise men and women of global finance.
