Russia has just dropped another bombshell, announcing not only the de-coupling of its trade from the dollar, but also that its hydrocarbon trade will in the future be carried out in rubles and local currencies of its trading partners – no longer in dollars – see Voice of Russia
Russia’s trade in hydrocarbons amounts to about a trillion dollars per year. Other countries, especially the BRICS and BRCIS-associates (BRICSA) may soon follow suit and join forces with Russia, abandoning the ‘petro-dollar’ as trading unit for oil and gas. This could amount to tens of trillions in loss for demand of petro-dollars per year (US GDP about 17 trillion dollars – December 2013) – leaving an important dent in the US economy would be an understatement.
