The dollar's fight for supremacy

Questions about the long-term viability of the dollar as the world’s supreme transaction and investment currency have been building up for years. But America’s chaotic foreign, economic and trade policies in the six months since Donald Trump returned to the White House have intensified doubts about whether the US currency will stay the course for the longer term. Will the US be knocked off its monetary pedestal in the next five years? And which currencies are in the running as the most potent rivals to the dollar?   Ellie Groves, head of strategy, official institutions group at State Street Investment Management, and David Marsh, chairman of OMFIF, debate the pros and cons of the dollar and other leading currencies, with reference to some of the themes in David’s new book, Can Europe Survive? The Story of a Continent in a Fractured World.
