See if any brains are out there. What happens if the USD Petrodollar ends? No links, this is just something you should know about already. The world trades Petrol based on the USDOLLAR. I know what has happened when that system has been challenged.........do you?
Petroleum-using countries buy dollars to use in oil purchases. That supports the value of the dollar so it makes foreign goods cheaper for US consumers. If the world used some other currency, the Euro for instance, the value of the dollar would fall. That could make foreign goods more expensive in the US and, consequently, domestic goods more attractive. Changing to another currency could be good for US workers.
