Interesting, commodity basket. Originally was usd to gold. Makes sense about reduced usd weighting. Yet dollar seems would have to decline first. All that currency dilution with stages of QE, makes for many more dollars liquid in system, and keeps the dollar sdr basis in tact too.
I believe before IMF does add gold as 6th sdr, its price has to be stable. The only way I know of is China, when they peg a fiat currency to oil this year via gold standard. Or Trump beats them to the punch. Bye bye petro dollar and hello petro yuan. That's what I would do.
