Norges Bank Investment Management models a potential downturn in global equities if artificial intelligence fails to deliver expected productivity gains, highlighting sector concentration risks and the role of bonds as a safeguard.
Norges Bank Investment Management has run a stark stress test of the sovereign wealth fund it manages, modelling a scenario in which the wave of investment behind artificial intelligence fails to translate into broad productivity gains. According to NBIM, that “AI correction” would see global equities fall by roughly 53%, trimming the fund’s value by about 35%, while fixed-income holdings would be the only major asset class to post gains of around 10% under the assumptions used. The manager’s analysis presumes central banks would react by pushing yields lower, boosting bond prices.
The potential hit is especially notable because NBIM is the largest single owner of listed shares worldwide, with a holding estimated at about 1.5% of all publicly listed equity. In its stress testing, the manager highlights how index concentration in a handful of technology names magnifies vulnerability: should the AI story falter, funds and indices weighted toward megacaps , including large US index trackers , would be disproportionately affected. The model identifies long-duration government bonds, such as those represented by the iShares 20+ Year Treasury ETF, as the only major asset class to deliver positive returns in the scenario.
The warning follows a period of market strain for the fund. NBIM reported a negative return in the first quarter of 2025 and a total fund value of 18,524 billion kroner as of 31 March 2025, with equity allocations accounting for about 70% of investments. News coverage noted a substantial quarterly loss driven largely by weakness among technology equities, underscoring how swings in a concentrated sector can ripple through a portfolio of NBIM’s scale.
Outside financial modelling, market participants have attempted to price the chance of a technology-led bust. On the prediction market Polymarket, a contract defining an “AI bubble burst” by 31 December 2026 , which requires specified large declines across several semiconductor and AI-related stocks within a 90-day window , was trading near the high teens in percentage terms, signalling a modest but non-negligible probability. Independent analysis of that market indicates the strict trigger conditions make a payout difficult and, at present, that only one of the required criteria has been met.
NBIM’s scenario carries wider implications for investors and portfolio construction. The test suggests that a renewed role for high-quality bonds as a hedge could re-emerge if a tech-led deflationary episode were to materialise and policy rates fell in response. At the same time, the concentration of market capitalisation in a small group of technology companies raises questions about diversification for investors who track broad US equity indices.
While NBIM reported strong calendar-year performance in 2025 before the first-quarter setback, the stress test is a reminder that even very large, diversified owners face asymmetric risks when rapid innovation concentrates returns in a few sectors. The manager’s modelling does not predict that outcome, but it does sketch the scale of loss that a pronounced disappointment in AI’s economic impact could inflict on global equity markets and on the world’s largest sovereign fund.
