When people talk about devaluing the dollar, as opposed to reissuing it completely, the natural question is, against what? What would one devalue it against officially if you do not wish to reinstitute a formal gold standard, which is clearly the preference of the Western central bank.
One likely candidate might be the SDR issued as a new currency for global trade, and for the pricing of international goods and commodities.
The major bone of contention as I have pointed out before would be the new 'basis' for the SDR.
What Will the World's Reserve Currency Become? The BRICs are adamant for the inclusion of additional currencies and gold and silver to make a portfolio that is less weighted to the US, Europe, and England.
A country would have the option to retain their own national currency for domestic use.
This is regards to devaluation as opposed to a hyperinflation and reissuance in which case old dollars would be scrapped for 'new dollars' with a couple of zeroes knocked off.
A friend sent this information about the US Post Office my way today. The speculation on the 'new composition' of the SDR is mine. I am assuming that the number of Euro countries decreases.
