Imagine a single currency, all around the world. No more converting between Dollars and Euros and Pounds, the money in your wallet is your ticket to ride anywhere.
Sound like a fantasy? Throughout history it’s been more or less the standard. The coins from one era might come from Rome or Madrid or London or Beijing, but one accepted unit of exchange was the norm until very recently. In many ways, the standard now comes from twelve Federal Reserve banks in paper form, printed with green ink.
But we’re a global society now, with total worldwide trade taking up nearly $8T of the global product of $52T. Is it time for a new global currency that isn’t subject to the needs and politics of one nation? More and more, the answer is “yes”. But getting there, as with anything international, is the hard part.
