Irak
Baghdad's switch from the dollar to the euro for oil trading is intended to rebuke Washington's hard-line on sanctions and to encourage Europeans to challenge it. But the political message will cost Iraq millions in lost revenue. RFE/RL correspondent Charles Recknagel looks at what Baghdad will gain and lose, and the impact of the decision to go with the European currency. 

Prague, 1 November 2000 (RFE/RL) -- Iraq is going ahead with its plans to stop using the U.S. dollar in its oil business in spite of warnings the move makes no financial sense.

Libyen
According to more than a few observers, Gadhafi’s plan to quit selling Libyan oil in U.S. dollars — demanding payment instead in gold-backed “dinars” (a single African currency made from gold) — was the real cause. The regime, sitting on massive amounts of gold, estimated at close to 150 tons, was also pushing other African and Middle Eastern governments to follow suit.

And it literally had the potential to bring down the dollar and the world monetary system by extension, according to analysts. French President Nicolas Sarkozy reportedly went so far as to call Libya a “threat” to the financial security of the world. The “Insiders” were apparently panicking over Gadhafi’s plan.
