From Britain's vote to leave the European Union to Donald Trump's championing of "America First," pressures are mounting to roll back the economic integration that has been a hallmark of gatherings of the IMF and World Bank for more than 70 years.

Fed by stagnant wages and diminishing job security, the populist uprising threatens to depress a world economy that International Monetary Fund Managing Director Christine Lagarde says is already "weak and fragile."

The calls for less integration and more trade barriers also pose risks for elevated financial markets that remain susceptible to sudden swings in investor sentiment, as underscored by recent jitters over Frankfurt-based Deutsche Bank AG's financial health.
