Norway's Massive Oil Fund Is Pulling $80 Billion Out of US Treasuries

A Historic Shift Away from US Government Debt

The manager of Norway's $2.3 trillion sovereign wealth fund has proposed significantly cutting its exposure to U.S. Treasuries as part of a wider shake-up of its bond investments to improve returns. It's a move that signals growing unease among the world's largest institutional investors about the reliability and profitability of American government debt — and the scale of it is hard to overstate.

Norges Bank Investment Management has recommended reducing its weighting to government bonds within its benchmark bond index to 50% from 70%, with U.S. Treasuries, the biggest holding, getting the biggest cut. The changes would mean cutting nearly $80 billion from the fund's current holdings of about $215 billion of U.S. Treasuries as of the end of June. To put that in perspective, $80 billion is larger than the entire GDP of many countries. When the world's biggest fund moves, markets pay attention.

Why Norway Wants Out — and Where the Money Is Going

CEO Nicolai Tangen and Norway's central bank chief, Ida Wolden Bache, said the fund could earn higher premiums by diversifying into riskier assets, such as mortgage-backed securities, which they judge as well positioned to weather as a long-term investor. The logic is straightforward: safe assets offer safety, but they also offer lower returns. For a fund of this size, even a fractional improvement in yield translates into billions of dollars.

Tangen and Wolden Bache said mortgage-backed securities, made infamous during the 2008 financial crisis, tend to move in the opposite direction to equities during crises and so could provide an "additional reduction of volatility" more similar to government bonds than corporate bonds. That's a nuanced argument — the fund isn't simply chasing risk, it's trying to engineer a smarter balance between safety and reward. Managers aim to lower the government bond weighting in the benchmark from 70% to 50%, freeing capital for corporate debt, mortgage-backed securities and other higher-yielding instruments.

While U.S. Treasuries exposure would fall, the proposed allocation to U.S. non-government debt would jump from 16.2% to 27.6%, meaning that the overall bond index's weighting to the U.S. dollar would fall only slightly, from 52.9% to 52.5%. In other words, this isn't a retreat from America — it's a reallocation within it, from government IOUs toward other types of American debt.

The Bigger Picture: Trouble in the Treasury Market

Government bond markets have been in turmoil recently, with long-term borrowing costs soaring as rising inflation and government debt levels spooked investors. Norway's fund is not alone in its hesitation. Across the globe, large institutional investors have been reassessing how much faith to place in government bonds as deficits balloon and inflation pressures persist.

This sovereign wealth fund, funded by Norway's oil and gas revenues, ranks as the world's largest with assets topping $2.3 trillion. NBIM currently holds around $1.65 trillion in equities — with ownership of almost 1.5% of all shares in the world's listed companies — and $592 billion in fixed income. The sheer breadth of its portfolio means its decisions ripple outward, influencing markets and signaling trends that smaller investors often follow.

What Happens Next

Norges Bank IM said it would await the ministry's feedback, adding that any changes would be implemented gradually to limit market impact and transaction costs. That gradual rollout matters enormously. Dumping $80 billion in Treasuries on the open market at once could destabilize prices — so the fund is signaling patience and discipline, not panic.

The proposal represents a broader reckoning in global finance. When the world's most conservative, best-capitalized long-term investor decides that U.S. government debt is no longer the best place to park its money, it raises pointed questions about American fiscal credibility. The proposal follows a finance ministry review and seeks greater diversification to improve returns without sacrificing liquidity during market stress. Whether other sovereign funds follow Norway's lead could determine just how significant a turning point this moment really is.
