From the article...
"Any move to water down the use of the U.S. dollar as the currency would have enormous symbolic impact, said one prominent Canadian energy analyst.
“On a symbolic level, I think it's huge, not only for what it says about the U.S. dollar, but also the implied change to the nature of energy trading worldwide in the future,” said Wilf Gobert, vice-chairman of Peters & Co. Ltd.
Beyond the blow to the greenback's prestige, a move by OPEC to even partly price in euros would ensure that any further depreciation in the U.S. dollar boosts oil prices, Mr. Gobert said. And any country — not just the United States — using the U.S. dollar for pricing would see the cost of the commodity rise as that currency fell.
Indeed, while OPEC has yet to make any formal break with the U.S. dollar, its refusal to boost output has already offloaded much of the cost of the dollar's depreciation on to the American economy. Mr. Gobert said oil prices at the end of last month, about $32 (U.S.) a barrel, would have been much lower if not for the decline in the value of the U.S. dollar over the past 24 months. Using the exchange rates of the dollar versus the euro two years ago, crude would be selling for $22 a barrel instead, he said."
It's the symbolic impact that will frighten investors, the ones that are too stupid to realize how screwed this country is in terms of financing the debt that is going out of control. And if the Resident makes his Richie Rich tax cuts permanent, the shit will hit the fan.
