UAO Fiduciary · The Long Horizon
A sovereign fund's real client may be a citizen who will not be born for decades. Duty has to stretch to meet them.
Most fiduciary duty is framed around present beneficiaries — the savers, pensioners and citizens who exist now and can be counted. For the largest, longest-lived owners, that framing is too short. A sovereign wealth fund built to last generations, or a pension system with liabilities running out half a century, has a real client who has not yet been born. The question is what, if anything, is owed to them.
It is not an abstract question. The decisions an owner makes today — about climate exposure, about the depletion of natural capital, about the resilience of the systems it invests in — distribute costs and benefits across time. Someone in 2075 will inherit the portfolio and the world it helped finance.
The tension inside the mandate
Intergenerational duty creates a genuine conflict, not a platitude. Maximising distributions to today's beneficiaries can come at the expense of tomorrow's; protecting the long-run corpus can mean asking the present to accept less. Every spending rule, every discount rate, every climate decision is implicitly an answer to how the fund weighs the living against the unborn.
The decisions an owner makes today distribute costs and benefits across time. Someone in 2075 inherits the result.
Sovereign funds confront this more sharply than anyone, because their mandate is often explicitly multi-generational. The Norwegian model — spend only the expected real return, preserve the capital forever — is a formal answer to the intergenerational question, and a reminder that the answer can be written into governance rather than left to sentiment.
Designing duty across time
The practical response is to make the future a party to present decisions. That means governance structures with long mandates and institutional memory, spending rules that protect the corpus, and explicit recognition that systemic risks like climate are transfers from future beneficiaries to current ones unless they are addressed now.
The Intergenerational Ledger, the recurring feature here, will take one decision at a time where today's and tomorrow's beneficiaries diverge, and ask how the duty should be weighed. The unborn beneficiary cannot sit on the investment committee. The owner's job is to make sure someone is keeping their seat.
The counter-case · the strongest opposing view
A strong counterargument gives priority to present, identifiable beneficiaries over hypothetical future ones. A pension's duty, on this view, runs to the people who contributed, and asking today's members to accept lower returns for distant, uncertain benefits is itself a breach. Deep uncertainty compounds the problem: betting the corpus on century-scale forecasts may be more reckless than prudent, and even the Norwegian spending rule is a political choice, not a fiduciary necessity. Intergenerational duty is a serious idea — but “the unborn beneficiary” can also become a licence to justify almost anything in the present.
UAO Fiduciary sets out the argument and the strongest counter-argument so allocators can weigh the evidence themselves. We report the debate; we do not pick a side.
