Norway Wealth Fund Proposes $80 Billion Cut to Its U.S. Treasury Holdings

Norway’s $2.3 trillion sovereign wealth fund has proposed cutting roughly $80 billion from its U.S. Treasury holdings as part of a major restructuring of its fixed-income benchmark designed to improve diversification and expected returns.

Norges Bank Investment Management, which manages the Government Pension Fund Global, recommended reducing government bonds to 50% of its bond benchmark from 70%. The change would lower U.S. government bonds to 21.9% of the fixed-income index from 34.1%, making Treasuries the biggest source of the proposed reduction. The recommendation is not yet approved and any transition would be gradual.

The distinction between a Treasury reduction and a retreat from U.S. assets is important. NBIM proposes replacing much of the government debt with other dollar-denominated fixed-income securities, including agency mortgage-backed securities. As a result, the U.S. dollar share of the bond benchmark would barely change, falling to 52.5% from 52.9%.

The proposal is significant for institutional investors beyond its potential effect on Treasury demand. The world’s largest sovereign wealth fund is effectively reassessing how much low-risk government debt it needs for liquidity and portfolio protection — and how much of its fixed-income allocation can instead be used to harvest additional risk premiums.

Government bond weighting would fall from 70% to 50%

Norges Bank set out the proposed changes in a Sept. 1 letter to Norway’s Ministry of Finance.

The fund’s bonds have three principal roles: reducing fluctuations in the overall portfolio, providing liquidity and generating risk premiums. Norges Bank concluded that those objectives remain appropriate but that government debt does not need to occupy as large a share of the benchmark as it does today.

Under the official Norges Bank Investment Management bond-strategy recommendation, the central bank said a 50% government-bond weighting would provide sufficient liquidity even during periods of financial-market turbulence.

The other half of the benchmark would be allocated to non-government investment-grade debt.

NBIM also wants to move the benchmark closer to the Bloomberg Global Aggregate and replace the GDP-based weighting currently used for government bonds with market-value weighting. The manager argues that elevated sovereign debt is now a widespread feature of developed economies rather than a problem concentrated in a small number of countries.

That change has consequences for the geographic composition of the portfolio.

U.S. government bonds would fall to 21.9% of the bond index from 34.1%. Euro-area government debt would decline to 14.1% from 16.8%, while Japanese government bonds would rise to 7.4% from 4.6%. The U.K. government-bond weighting would remain at 4.2%.

Nearly $80 billion could move out of Treasuries

NBIM held about $215 billion of U.S. Treasuries at the end of June. Applying the proposed benchmark changes would imply a reduction approaching $80 billion, according to Reuters calculations.

That is substantial for a single institutional investor, although the adjustment would not occur as an immediate sale.

NBIM said it would wait for the Ministry of Finance’s response and that any implementation would be gradual to limit transaction costs and market impact. The proposals are expected to feed into recommendations in January 2027 and Norway’s annual sovereign wealth fund policy process before a final government recommendation goes to parliament. The Reuters report on Norway’s proposed Treasury reduction provides the approximately $80 billion estimate based on current holdings.

The source article supplied for this story incorrectly states that the change could remove nearly $800 billion from approximately $215 billion of Treasury holdings. The underlying reporting and Reuters calculation put the figure at approximately $80 billion, which PE NEWSWIRE is using here.

The fund is not abandoning dollar-denominated debt

The proposed allocation makes the investment rationale clearer.

U.S. non-government bonds would rise to 27.6% of the fixed-income benchmark from 16.2%, almost offsetting the 12.2-percentage-point reduction in U.S. government securities. Overall dollar exposure would therefore decline by just 0.4 percentage point.

Agency mortgage-backed securities are particularly important to the new structure.

These securities are backed by mortgages and guaranteed by Fannie Mae, Freddie Mac or Ginnie Mae. NBIM considers their credit quality close to U.S. government bonds, while the securities provide additional returns partly in exchange for risks such as borrowers repaying mortgages earlier than expected.

That makes the proposal less a bearish call on the U.S. than a reconsideration of how the fund earns returns from its fixed-income allocation.

The distinction also matters amid speculation about foreign investors reducing exposure to U.S. assets. NBIM’s proposed benchmark would retain approximately the same dollar weighting while changing the type of dollar assets it owns.

Bond selloff strengthens the case for reviewing sovereign exposure

The proposal arrives during a difficult period for global government bonds.

U.S. long-term yields have climbed sharply amid renewed inflation pressure, rising government borrowing and concerns about the fiscal outlook. Japan’s 10-year government bond yield reached 3% on Sept. 1 for the first time since 1996, while the U.K. 10-year gilt moved above 5.2%. The U.S. 10-year Treasury yield approached 4.8%.

PE NEWSWIRE recently examined how the global bond selloff is raising financing costs across alternative assets in its analysis of global bond yields and private-market financing risks.

For institutional portfolios, higher sovereign yields have competing effects. They increase the prospective income available from government debt but can also generate mark-to-market losses on existing long-duration holdings when yields rise.

NBIM’s proposal addresses a longer-term portfolio-construction question rather than simply reacting to the latest market move. The manager’s analysis concludes that reducing government bonds would not necessarily materially weaken fixed income’s ability to dampen overall portfolio volatility.

Government bonds would still represent half of the benchmark, preserving a substantial pool of liquid securities for portfolio rebalancing during stressed markets.

Norway is also examining greater access to unlisted assets

The bond review sits alongside another strategic question with more direct implications for private markets.

NBIM has separately recommended considering greater investment in unlisted assets as the fund confronts increasing concentration in public equity markets. The fund currently has permission to invest in unlisted real estate and renewable-energy infrastructure, but its private-market exposure is more limited than that of several comparable sovereign and pension investors.

That issue is becoming more relevant as the enormous scale of sovereign wealth and pension portfolios changes how institutional investors approach diversification.

Norway presents a much larger portfolio-construction challenge.

Government Pension Fund Global owns, on average, about 1.5% of all listed companies worldwide. With a portfolio of roughly $2.3 trillion, even modest strategic allocation changes can involve tens of billions of dollars.

Moving a larger portion of that portfolio toward unlisted assets would consequently have implications for private equity, infrastructure, real estate and potentially other alternative strategies, depending on the mandate ultimately authorized by Norway.

A portfolio-construction shift, not a flight from America

The proposed Treasury cut is therefore best understood as a strategic reallocation within fixed income rather than a wholesale reduction in Norway’s exposure to the United States.

Treasuries would decline materially, but U.S. mortgage-backed and government-related bonds would absorb much of the difference. Dollar exposure would remain close to 53%, and the fund’s enormous U.S. equity portfolio is not part of the proposed bond-index restructuring.

For institutional investors, the broader significance is the reasoning behind the change.

NBIM is concluding that it can meet liquidity requirements with a smaller government-bond allocation while using a larger portion of fixed income to capture other risk premiums. At the same time, Norway is debating whether greater use of unlisted assets could address concentration elsewhere in the portfolio.

Those two discussions point toward the same portfolio challenge facing large asset owners: how to balance liquidity and resilience against the return and diversification benefits available from taking additional credit, liquidity and private-market risk.

If Norway ultimately adopts the recommendations, the approximately $80 billion Treasury reduction will be the most visible consequence. The more consequential long-term change may be the willingness of the world’s largest sovereign wealth fund to reconsider where a multi-trillion-dollar portfolio should take risk — across both public fixed income and private assets.
