A tight U.S. presidential election race has unnerved investors in emerging markets, who fear a return of former President Donald Trump to the White House could hurt emerging markets just as they were poised to shine. But analysts are now concerned that under a second Trump presidency trade barriers could be buttressed, spurring a rebound in inflation and thereby interest rates, lifting the dollar and eventually weighing on emerging markets again. "Normally this would be a good macro backdrop for emerging markets: resilient growth, continued disinflation and a weak dollar," Arun Sai, senior multiasset strategist at Pictet Asset Management, told the Reuters Global Markets Forum (GMF).
