Dream of Universal Currency Just Won’t Die

• David Wolman via

The euro zone maelstrom refuses to end. Thanks to the debt crisis, some Greek officials are contemplating dumping the common currency for the drachma. Meanwhile, Italy and Spain teeter. A decade after the shared currency was heralded as a 21st-century tool for peace and prosperity, it turns out that currency unions aren’t such a hot idea.

Not so fast, though. This is undeniably a period of epic turmoil, and many economists will tell you that sovereign states need sovereign currencies—full stop. But this notion ignores a fundamental truth: Countries with their own currency may have monetary independence, but in reality—as gun battles in Libya, CDOs in the US, and tsunamis in Japan have taught us—we are only becoming more economically intertwined, regardless of what our coins look like.

Step back from the current crisis to consider the long view, and currency unions—or even a single global currency—have a fair share of appeal. A universal medium of exchange could eliminate currency risk and jack up trade. It would mean speculators couldn’t short an individual country’s currency. Exporters wouldn’t have to fret over the gap between a price on a contract and the value of the payment. A single currency could halt spastic swings in prices and end conversion fees, leaving more of the pie for little stuff like R&D and employee health insurance. Oh—and it could put an end to international disputes over currency manipulation. Hello? China?
