Key Takeaways
- • Norges Bank Investment Management, the world's largest sovereign wealth fund with $2.3 trillion in assets, proposed in a letter to Norway's finance ministry that its benchmark bond index slash government debt, which would mean offloading about $80 billion of U.S. Treasury securities.
- • The reduction in Treasuries would be largely offset by purchases of non-government U.S. debt, including agency mortgage-backed securities, with U.S. Treasuries trimmed by 12.2 percentage points and non-government U.S. debt rising by 11.4 percentage points.
- • Total dollar-denominated exposure would stay roughly flat at 52.5% under the proposal versus 52.9% today, according to the fund's letter.
- • The overall government bond weighting in the benchmark would fall to 50% from 70%, with U.S. government bonds dropping to 21.9% from 34.1% and Japanese government bonds rising to 7.4% from 4.6%.
- • The fund characterized the changes as a realignment to broader market weightings, though the move comes amid U.S. fiscal concerns, with national debt at $40 trillion and the federal deficit on track to hit $2 trillion this fiscal year.
Summary
Norges Bank Investment Management (NBIM), the world's biggest sovereign wealth fund with $2.3 trillion in assets, has proposed reshuffling its U.S. debt holdings away from Treasuries. In a letter to Norway's finance ministry on Tuesday, the fund's manager recommended cutting government debt in its benchmark bond index. If adopted, the change would result in roughly $80 billion of U.S. Treasury securities being offloaded, according to the report.
The reduction would be mostly offset by purchases of riskier forms of U.S. debt, including mortgage-backed securities (MBS). The fund argued that MBS risk stems not from default but from the prepayment risk that arises when mortgages are refinanced at lower rates, benefiting borrowers over investors, and that MBS carry a prepayment premium to compensate. The letter stated that agency MBS are guaranteed by Fannie Mae, Freddie Mac and Ginnie Mae, and that "the credit quality is close to that of US government bonds." It said: "Norges Bank's advice is that securitized bonds (including mortgage-backed securities, so-called agency MBS) and government-related bonds should be included in the bond index," adding that "a broad market index provides exposure to more risk premiums and gives a more diversified benchmark index than today."
Under the proposed rebalancing, U.S. Treasuries would fall 12.2 percentage points while the share of non-government U.S. debt would rise 11.4 percentage points. Overall exposure to dollar-denominated assets would remain largely unchanged at 52.5%, versus 52.9% under the current portfolio. Across the benchmark, U.S. government bonds would drop to 21.9% from 34.1%, euro zone government debt would dip to 14.1% from 16.8%, Japanese government bonds would rise to 7.4% from 4.6%, and UK government bonds would be unchanged at 4.2%. The overall government bond weighting would fall to 50% from 70%.
The proposal was framed by the fund as a realignment to match broader market weightings. Governor Ida Wolden Bache and NBIM CEO Nicolai Tangen wrote that "a government share of 50% will be sufficient to cover the liquidity needs, including in periods of turbulence in financial markets." The article notes the timing is politically sensitive: U.S. national debt has reached $40 trillion, the federal deficit is on track to hit $2 trillion this fiscal year, and the article cites recent U.S. trade conflicts and geopolitical tensions as factors that have led some investors to view holding dollar assets as riskier, given the possibility of U.S. sanctions. Dollar-denominated assets such as Treasuries also make up a smaller share of global central bank reserves than before, with gold accounting for a larger share.
