The head of the World Economic Forum (WEF) has warned that the global economy may be on the brink of three simultaneous financial bubbles — in artificial intelligence, cryptocurrencies, and sovereign debt — as markets reel from sharp declines in major technology stocks.
Speaking to reporters during a visit to São Paulo, Brazil’s financial hub, WEF President Børge Brende said the extraordinary optimism fueling market highs could soon give way to a painful correction. “We could possibly see bubbles moving forward. One is a crypto bubble, second an AI bubble, and the third would be a debt bubble,” Brende said. “Governments have not been so heavily indebted since 1945.”
His comments come after a wave of selling hit global tech stocks this week, wiping billions from the valuations of leading companies. While analysts say the downturn is not yet a cause for panic, many warn that investors’ enthusiasm — particularly around artificial intelligence — has stretched valuations to unsustainable levels.
For months, financial markets have brushed off concerns about high interest rates, persistent inflation, and global trade disruptions, surging on expectations that AI could transform productivity and drive a new era of economic growth. But Brende cautioned that the same forces propelling optimism could also bring severe dislocation to the workforce. “AI offers the possibility of big productivity gains,” he said, “but it could also threaten many white-collar jobs.”
He cited the risk of a “new Rust Belt” emerging in major cities whose economies depend heavily on back-office and administrative roles — positions increasingly vulnerable to automation. Companies such as Amazon and Nestlé have already announced job cuts linked to restructuring and the adoption of AI-driven technologies.
Despite these concerns, Brende struck a note of cautious optimism, recalling that technological revolutions throughout history have ultimately led to higher productivity and improved living standards. “We also know from history that technological changes over time lead to increased productivity,” he said. “And productivity is the only way over time to increase prosperity. Then you can pay people better salaries, and you have more prosperity in society.”
Still, his warning about the “triple bubble” underscores growing unease among global policymakers and economists that financial markets may once again be ignoring fundamental risks. With governments burdened by post-pandemic debt, investors chasing speculative tech bets, and AI reshaping economies at breakneck speed, the world’s financial system, Brende suggested, could be heading toward its next major stress test.
