The IMF had first advocated a new global fiat currency in a paper from April 2010 (PDF) where the new currency was titled "Bancor".
UPDATE: The video has been removed recently. Ron Paul's message is transcripted below.
Transcript of Ron Paul's speech:
"Right now we have a financial crisis. They know it as much as we do and they are planning, but they are planning an international answer to this. They are planning through the IMF to come up with a world currency to replace the dollar because the dollar will be replaced. You just can't keep printing them forever. They are gonna have to attempt to restore confidence but they wanna come up with another paper currency controlled and ruled by the United Nations and the IMF. I would suggest very strongly that we need to send a powerful message to those individuals in charge, by showing them that we are not a small minority any longer and we are constantly growing and we are going to have a lot of influence with the future of this country."Click here to go to the The Prudent Investor homepage for more interesting posts.
