Record first-half 2026 performance

The warning came on the same day the fund reported its best half-year performance ever. NBIM posted a record profit of 1.75 trillion Norwegian crowns (~$184–$185 billion) for the first six months of 2026 . The return was 9.4% in Norwegian kroner — the highest in the fund’s history in that currency — and the overall first-half equity return was 12.95% . The gains were powered by a tech and semiconductor rally, particularly in Asian stocks such as Samsung, SK Hynix, TSMC, ASML, Intel, and Nvidia . Tangen described the result as driven by “good returns in the equity market, particularly from Asian technology stocks” .

Despite the record numbers, Tangen urged investors not to expect “the same kind of returns going forward as we’ve seen over the last few years” . He described current financial markets as being in an “abnormal situation,” where prices kept rising despite persistent global challenges .

The downside scenarios that could wipe out the fund

Tangen laid out several extreme downside scenarios, drawn from NBIM’s internal risk models :

• AI bubble bursting — A correction in overheated AI-driven valuations. NBIM’s risk models show this could cause a decline of up to 35% of the fund’s value, representing roughly $700 billion at current valuations .
• Severe geopolitical upheaval / US-China trade war — A prolonged economic depression combining multiple shocks, including an AI bubble bursting alongside a US-China trade war, which Tangen said could wipe out at least 80% of stock market investments, similar to the Great Depression of 1929 .
• Nuclear war — Explicitly named as a scenario that could render the financial fund “worthless” .
• Biological terrorism — Also named as a catastrophic risk that could destroy the fund entirely .
• Prolonged global depression — A broader multi-shock scenario severe enough to destroy the vast majority of the fund’s equity exposure .

A 30-year run of growth under threat

2026 marks 30 years since Norway deposited its first payment, a precise sum of 1,981,128,502 kroner and 16 øre, into what became the Government Pension Fund Global . Since then, the fund has grown into the largest sovereign wealth fund on earth, owning approximately 1.5% of all listed companies globally .

Tangen’s overarching message was that the fund’s extraordinary growth should not be taken for granted, and that “tougher times ahead” are likely for equity investors . He first raised the alarm as early as April 2025, identifying the splintering of the global economy as the single biggest threat to financial markets, and reiterated those concerns in March 2026 after conflict erupted in the Middle East .
