Norway’s USD 2.3 trillion sovereign wealth fund, the world’s largest, has proposed cutting its holdings of US Treasury bonds by about USD 80 billion as it seeks higher returns and greater diversification in its fixed-income portfolio.
Norges Bank Investment Management (NBIM), which manages the Government Pension Fund Global, has recommended reducing the share of government bonds in the fund’s benchmark bond index to 50% from 70%. US Treasuries, currently the fund’s largest government bond holding, would bear the biggest reduction.
The proposal represents a significant change for one of the most important long-term investors in global financial markets.
The proposed shift would reduce US Treasury exposure from roughly 34.1% of the fund’s fixed-income portfolio to about 21.9%, according to estimates reported by the Wall Street Journal.
However, the move does not represent a broad retreat from US assets or the US dollar.
The fund argues that these securities offer credit quality close to US government bonds while providing the potential for better returns. The proposed changes would therefore alter the composition of its US bond exposure rather than eliminate it.
NBIM also expects the fund’s overall US dollar exposure to remain broadly unchanged. Reuters reported that the dollar allocation would remain at about 53%, underscoring that the strategy is aimed primarily at improving the risk and return characteristics of the bond portfolio rather than making a currency or geopolitical bet against the US.
The timing is significant. Global government bond markets have experienced heightened volatility as investors contend with elevated inflation risks, higher borrowing requirements, and concerns about the sustainability of government debt.
Long-term bond yields have risen in several major markets, putting pressure on the prices of existing government bonds. The fund’s proposed reallocation would give it greater exposure to securities that could offer higher income while reducing its dependence on sovereign debt.
For the US Treasury market, the proposed reduction is relatively small compared with the enormous size of the government debt market. But its significance goes beyond the immediate amount involved.
The Norwegian fund is a major institutional investor, and its decision could reinforce concerns about whether traditional buyers of US government debt are becoming less willing to maintain large allocations to Treasuries.
Economist Mohamed El-Erian described the signal as more important than the size of the proposed sale, arguing that the reliability of traditional holders and buyers of US government debt is relevant for the market.
The move also comes as governments globally are issuing increasing amounts of debt to finance spending and refinance existing obligations.
For Norway’s fund, however, the decision is primarily about portfolio construction.
That approach reflects the fund’s unusually long investment horizon. Its mandate is to maximise returns while accepting market fluctuations, and its investment strategy is determined by Norway’s Ministry of Finance, with significant changes requiring parliamentary approval.
The proposal is not yet final. Norway’s finance ministry will consider the recommendation, with the changes expected to be incorporated into a broader policy process and ultimately presented to parliament in 2027.
The proposed Treasury reduction nevertheless sends a clear message to global bond markets: even investors traditionally regarded as stable, long-term buyers of US government debt are reassessing how much exposure they want to the world’s biggest sovereign borrower.
For Washington, the immediate impact may be limited. But if other major institutional investors follow Norway’s lead, the cumulative effect could make the cost of financing America’s expanding debt burden an increasingly important concern for global markets.
