London CNN —The two biggest economies in South America are starting talks to create a common currency. At a press conference in Buenos Aires, he said establishing a common currency for trade would reduce reliance on the US dollar, whose sharp ascent last year was painful for countries around the world. Talk of creating a common currency has periodically cropped up since its founding in 1991. Still, investors are doubtful efforts to create a common currency in the region will gain much traction. “Brazil and Argentina are a long way away from the convergence in economic policy and performance required to launch [a] monetary union,” he said.
