WEF president: 'We haven't seen this kind of debt since the Napoleonic Wars'

Borge Brende, president of the World Economic Forum, gave a stark outlook for the global economy saying the world faces a decade of low growth if the right economic measures are not applied.

He also motioned persistent inflationary pressures and that generative artificial intelligence could be an opportunity for the developing world.

His warning chimes with a recent report from the International Monetary Fund which noted that global public debt had edged up to 93% of GDP last year, and was still 9 percentage points higher than pre-pandemic levels. The IMF projected that
