Norway’s sovereign wealth fund wants to cut U.S. Treasury exposure as it diversifies.
Why it matters: A shift from the world’s largest sovereign wealth fund can ripple through Treasury markets and global bond allocation trends. Reserve managers and large long-horizon investors often watch Norway’s benchmark moves closely.
- Norges Bank Investment Management recommended cutting the government-bond share of its bond benchmark from 70% to 50%.
- The proposal was sent in a letter dated September 1, 2026, to Norway’s Ministry of Finance.
- Reuters calculations based on the letter put U.S. Treasury weight in the bond benchmark at 21.9%, down from 34.1%.
- NBIM says corporate bonds, covered bonds and mortgage-backed securities can improve diversification and add risk premiums.
Norges Bank Investment Management, which runs Norway’s roughly $2.3 trillion Government Pension Fund Global, is asking to reduce the government-bond share of its fixed-income benchmark from 70% to 50%. The recommendation was laid out in a Sept. 1 letter to Norway’s Ministry of Finance, which oversees the fund’s mandate. NBIM said the change would still leave enough liquidity to handle turbulence in financial markets.
The move would not just affect U.S. Treasuries. It would also change the mix of the broader government-bond sleeve, including allocations to euro-area and Japanese government bonds. Reuters calculated that the proposed shift would lower the U.S. Treasury share of the bond benchmark to 21.9% from 34.1%, implying about an $80 billion reduction if fully implemented. Reuters reported the fund held about $215 billion of Treasuries at the end of June 2026.
NBIM said a larger role for corporate bonds, covered bonds and mortgage-backed securities would improve diversification and give the fund exposure to risk premiums. Its current bond portfolio is split 70% government and government-related bonds and 30% corporate-sector securities. The fund said its analysis indicated that cutting the government-bond share would not necessarily materially weaken the portfolio’s ability to reduce fluctuations in the fund.
The proposal is a policy recommendation, not an executed sell-down. Any decision now sits with Norway’s Ministry of Finance.
By the numbers
- 2.3 trillion - approximate size of Norway’s Government Pension Fund Global
- 70% to 50% - proposed cut in the government-bond share of the bond benchmark
- 34.1% to 21.9% - Reuters-calculated drop in U.S. Treasury weight under the proposal
Yes, but: This is a recommendation, not a completed reallocation. The Ministry of Finance has not yet responded in the sources reviewed.
What's next: Norway’s Ministry of Finance will decide whether to adopt the recommendation.
