The Globe and Mail reports in its Saturday edition that since the end of the Second World War, the United States emerged as the unrivalled global hegemon and created the dollar-based world trading system. Contributing columnist John Rapley writes that in a geopolitical crisis, investors from all over the world would rush to the safety of U.S. assets. But despite the breakout of a major war in the Middle East, the dollar continues weakening and U.S. bond yields remain on an upward trajectory. Instead, everyone is rushing to buy gold. Driving the erosion of America's haven status has been the presidency of Donald Trump. His erratic policy-making, tariffs and threats to default on debt have diminished the attractiveness of U.S. assets. Americans have shown they are prepared to elect a president committed to smashing the institutional framework that has underpinned American hegemony. We are moving toward a postdollar world. In the Financial Times, Scotiabank head Scott Thomson wrote that Canadians are "coalescing" to "unlock the country's economic potential," and that this could be the watershed year in which the country reinvents itself. That sense of optimism is something Canadians should seize on while it lasts.
