Economists at 2026 Bund Summit Warn of AI Investment Risks
The 2026 Bund Summit, held in Shanghai on October 19, brought together economists to discuss risks from the global AI investment boom. The event was co-hosted by the China Finance 40 Forum (CF40) and Tsinghua University, with several participants drawing parallels between today's imbalances and those preceding the 2008 subprime crisis.
Donald Kohn, former vice chair of the U.S. Federal Reserve, said AI expansion is affecting demand before supply. Large technology companies such as Google and Microsoft are spending heavily on data centers, chips and engineers, creating current demand for electricity, steel, construction and jobs, while the productivity gains AI promises have not yet materialized. Philip Lane, chief economist of the European Central Bank, said the AI global supply chain boosted euro-area trade in 2026, with overall investment rising about 10% because of AI. He noted that wage growth has been moderate, as workers fear AI replacing jobs and companies worry about intensifying competition from China.
Huang Yiping, dean of Peking University's National School of Development, warned that the "Engels pause" deserves attention. If AI's technological dividends favor capital more than labor, income distribution could worsen and fiscal and tax structures could be strained, since labor income is taxed more heavily than capital income under current systems. Klaas Knot, former president of De Nederlandsche Bank, warned that about one-third of the AI investment boom is financed by debt, and off-balance-sheet commitments may mean the true share is higher. If large technology companies fail to honor huge purchase commitments, a chain collapse could follow.
Ceyla Pazarbasioglu, former director of the IMF's Strategy, Policy and Review Department, said that as the geo-economy fragments and financial systems become more opaque, leverage combined with opacity is the most dangerous combination. Participants generally said the possibility of significant market corrections should not be underestimated, and that a U.S. correction could quickly spread from equities to consumption, employment and the broader economy because American consumption is sensitive to wealth effects.
