Norway wealth fund CEO warns collapse ‘not improbable’ after record $184B half-year gain

Nicolai Tangen, the chief executive of Norges Bank Investment Management, warned on Monday that Norway's $2 trillion sovereign wealth fund could theoretically lose its entire value, calling the scenario "not completely improbable" given current global tensions — a stark message delivered just as the fund reported its best half-year performance in history.

"Can the Oil Fund Disappear? The Answer Is Yes"

Speaking at a political conference in Arendal, southern Norway, on August 11, Tangen said he wanted to contribute to the country's "mental emergency preparedness" by posing the question directly.reuters+1

"Can the oil fund disappear? The answer to that question is 'yes' and the worst is that in the world we live in now, it is not completely improbable," Tangen said, according to Reuters.reuters

The fund, which invests Norway's oil and gas revenues in stocks, bonds, and property abroad, has doubled in value in less than a decade and now covers about a quarter of the country's public spending. It owns an average of 1.5% of every listed company globally.kucoin+1

Tangen described the last three decades of low taxes, inflation, and interest rates as "abnormal" — precisely the period in which the fund grew to its current size. He compared elements of today's environment, including tariffs, to conditions preceding the 1929 Great Depression, when U.S. stocks lost nearly 90% of their value.straitstimes+1

Stress Tests Reveal Alarming Scenarios

In an interview with Bloomberg following the fund's record first-half results — a 9.4% return equivalent to roughly $184 billion in gains — Tangen outlined specific downside scenarios from the fund's own stress tests.cryptobriefing+1

An AI bubble bursting could shave approximately 35% off the fund's total value, while a severe geopolitical upheaval could trigger a 37% decline, roughly $770 billion in losses. Among extreme scenarios, Tangen also mentioned nuclear war and biological terrorism as threats that could devastate the portfolio.straitstimes+1

The fund's equity portfolio, which comprised 71.3% of assets at the end of 2025, returned 13% in the first half of 2026, led by Asian technology stocks. Major holdings include stakes in Nvidia ↘ 1.47%, Apple ↘ 0.80%, and Alphabet ↘ 3.58%.ibtimes

Resilience Amid the Warning

Despite the grim scenarios, Tangen acknowledged that markets have defied expectations. "If you were going back two years, if you had predicted tariffs, trade barriers, you would not have expected the market and the economy to be as strong as it is. So it is a resilient economy," he told Reuters.reuters

The tension in his message captures a broader unease among institutional investors: the steward of the world's largest fortune is war-gaming a total loss while markets sit near record highs.
