A Single Global Currency would be managed by a Global Central Bank within a Global Monetary Union. The benefits: - Annual foreign exchange transaction costs of $400 billion will be eliminated. - Global currency imbalances, including all balance of payment issues, will be eliminated. - Currency crises will be prevented. - Currency fluctuations will be eliminated, as will be currency speculation. No more ups and downs for the U.S. dollar, the euro or any other currency. - Worldwide interest rates will be reduced due to the elimination of currency risk. - Worldwide asset values will increase by about $36 trillion. - Worldwide GDP will increase by about $9 trillion. - The need for foreign exchange reserves (currently about $5 trillion) will be eliminated. If 15 European, 14 African, and 7 Caribbean countries can share common currencies, then why not a common currency for countries totaling 50%, then 60%, then 75% and then 100% of the world's GDP?
