Norway's $2.3 trillion Government Pension Fund Global (GPFG), the world's largest sovereign wealth fund, has proposed a substantial shift in its fixed-income strategy. Norges Bank Investment Management (NBIM), which manages the fund, recommended cutting the government bond allocation from 70% to 50% of its bond portfolio. This move is designed to reduce the fund's concentration in government debt, provide liquidity, and enhance returns through exposure to a broader range of risk premiums in the bond market.

This proposed reduction would lead to a decrease of approximately $58 billion in overall government bond holdings. Specifically, holdings of US Treasuries are projected to drop significantly, with estimates ranging from $75 billion to $106 billion, potentially decreasing their share in the fund's bond benchmark from 34% to around 22%. Conversely, allocations to Japanese government bonds could increase by $20 billion, and euro-area government bonds are also expected to decrease. These changes reflect a move towards weighting the bond index by market value instead of gross domestic product.

While this proposal involves a substantial rebalancing, NBIM's simulations suggest that a 40% government share would suffice for liquidity needs, but a 50% target is recommended for greater safety. The shift would involve reallocating funds from government bonds to other forms of debt, such as corporate bonds, securitized bonds, and government-related bonds, including agency mortgage-backed securities. Analysts like Kenneth Crompton from National Australia Bank Ltd. noted that NBIM's rationale is to harvest a broader set of fixed-income risk premia, not a direct call on US fiscal sustainability.

The Norwegian Ministry of Finance is set to review these recommendations and present them to parliament in the spring as part of a white paper on the fund. Karin Thorburn, a Norwegian School of Economics professor, viewed this as a positive step but suggested that a better approach might be to increase overall equity allocation and reduce bonds. The fund's CEO, Nicolai Tangen, has previously cautioned about potential market downturns, emphasizing the need for strategic adjustments.
