Norway’s $80 Billion Treasury Retreat Is the Canary In the Bond Market

Norway’s $2.3 trillion sovereign wealth fund has proposed drastically reducing its share of government bonds.

The world’s largest fund of its type might trim its holding from 70% to 50%. According to Bloomberg, such a change would cut its US Treasury portfolio by $75 to $80 billion.

The proposal from Norges Bank Investment Management (NBIM) lands at arguably the worst moment for sovereign debt in a long time. The US 10-year yield sits near 4.8%, its highest since January 2025; interest payments on US public debt have more than doubled in five years to over 3% of GDP, and elevated issuance from Japan, the UK and France is colliding with the vast borrowing needed to finance the AI boom.

While NBIM frames its move as a hunt for broader fixed-income risk premia, the signal to allocators is harder to ignore.

The Fading Luster of the Risk-Free Benchmark

In a letter to the Finance Ministry, NBIM argued the remaining half of its bond allocation should “provide exposure to more sources of risk premiums.” Government bonds currently make up about 59.5% of its $615 billion fixed-income book, or 69% including government-related debt. Any change requires parliamentary approval, and the fund has been rebuffed before, notably on private equity.

“A government share of 50% provides a comfortable margin to the estimated upper limit for the liquidity needs,” Norges Bank said.

“NBIM isn’t making a direct call on US fiscal sustainability,” said Kenneth Crompton, head of rates strategy at National Australia Bank. “They’re arguing that they already own enough government bonds to satisfy liquidity needs, and that a long-horizon investor should harvest a broader set of fixed income risk premia.”

Yet, academia is providing a clearer insight. According to Espen Henriksen from Norwegian Business School, when equities fall, the safety and liquidity benefit of government bonds over corporate debt is diminishing.

With AI hyperscalers already exceeding $270 billion in corporate debt year-to-date, NBIM has a large enough market to choose from. Even Oracle, which has the lowest rating in the group (BBB), remains within the investment-grade framework, albeit at the lower end.

Finally, the allocation reductions might be tied to broad deficit issues.

“Debt and deficits are unsustainable in most of the advanced economies,” said Nick Ferres, CIO at Vantage Point Asset Management. “At some point there will be a fiscal crisis.”
