The Oman Investment Authority (OIA) is Oman's sovereign wealth fund, managing roughly $60 billion across two mandates: a National Development Fund for domestic projects and a Future Generations Fund for global investments. It reported record profit and a 14.6% capital return in 2025.
The Oman Investment Authority (OIA) is the Sultanate of Oman's sovereign wealth fund — the institution charged with turning the country's finite hydrocarbon wealth into a permanent, diversified financial base. With roughly $60 billion in assets, it is not among the largest funds in the world, but its 2025 results put it firmly among the best-performing, and its governance model makes it one of the more instructive smaller Gulf funds for universal owners to watch.
What is the Oman Investment Authority?
OIA was established in 2020 by Royal Decree, consolidating two predecessor institutions — the State General Reserve Fund and the Oman Investment Fund — into a single sovereign investor. The merger was part of a broader push to professionalise Oman's public finances, unify a fragmented investment mandate under one board, and align the fund with the country's "Oman Vision 2040" economic diversification agenda.
Like most Gulf sovereign funds, OIA exists to solve a structural problem: the Sultanate's budget has historically depended on oil and gas revenue, which is both finite and volatile. A sovereign wealth fund converts a share of that resource income into financial capital that can generate returns long after the wells decline. But OIA's mandate is deliberately dual-purpose — it is expected both to earn global returns and to help build Oman's domestic economy.
How is OIA structured?
OIA runs two distinct portfolios, each with a different mandate and time horizon.
The National Development Fund (NDF) invests inside Oman in strategic sectors the government wants to grow — energy, logistics, mining, telecoms, manufacturing and tourism. Its job is developmental as much as financial: seeding national champions, attracting foreign co-investment, and diversifying the domestic economy away from crude oil. Roughly two-thirds of OIA's total assets sit inside Oman, reflecting the weight of this mandate.
The Future Generations Fund (FGF) is the outward-facing, savings-oriented pool. It invests in global public equities, fixed income, private equity, real estate and infrastructure, with an increasingly explicit tilt toward technology, artificial intelligence, healthcare, fintech and the energy transition. This is the portfolio designed to preserve and grow national wealth for the decades after hydrocarbon income fades — the "future generations" the fund is named for.
This two-fund architecture is common across the Gulf: it separates the developmental, domestically anchored capital from the globally diversified savings capital, so that each can be governed and measured against the right benchmark.
How much does the Oman Investment Authority manage?
OIA's assets reached approximately OMR 23 billion — about $60 billion — by the end of 2025. That places it in the middle tier of sovereign wealth funds globally, dwarfed by neighbours such as Abu Dhabi's ADIA (around $1.1 trillion), Saudi Arabia's Public Investment Fund and the Kuwait Investment Authority (which has crossed $1 trillion).
What OIA lacked in scale in 2025 it made up for in performance. The fund reported a record annual profit of roughly $7.5 billion and a capital return of about 14.6% for the year — a figure that ranked it among the strongest-returning sovereign funds in the world and, on some measures, first among sovereign funds for returns from public markets. For a fund of its size, generating a profit equal to more than a tenth of its asset base in a single year is a striking result, driven substantially by a well-timed public-equity allocation.
Where does OIA invest?
OIA's portfolio spans more than 52 countries. The geographic split reflects its dual mandate: with around two-thirds of assets inside Oman, the international remainder is weighted toward North America (roughly 19% of the total portfolio), Europe (around 9%), Asia-Pacific (around 4%) and other markets (around 7%).
On the international side, OIA has leaned into innovation-driven sectors. It has committed capital through venture managers such as Khosla Ventures and Lanchi Ventures, targeting artificial intelligence, robotics, climate technology and advanced healthcare. This is characteristic of a newer generation of Gulf sovereign investors that treat frontier technology not merely as a financial bet but as a channel for transferring capability, jobs and expertise back home.
What is OIA's divestment programme?
One of OIA's more distinctive features is its divestment programme, launched in 2022. Rather than simply accumulate assets, the fund actively sells mature domestic holdings — often via public listings or stake sales to strategic partners — to recycle capital into higher-returning opportunities and to deepen Oman's capital markets.
By the end of 2025, the programme had completed 24 divestitures and released more than $7.3 billion for reinvestment. This matters for two reasons. First, it demonstrates a discipline that many state investors lack: the willingness to exit assets rather than hold them indefinitely for prestige. Second, it supports a policy goal — broadening private ownership and building out the Muscat Stock Exchange — that extends beyond the fund's own balance sheet.
Why does OIA matter to universal owners?
For the world's largest allocators, OIA is worth understanding for reasons that outrun its size.
It is a case study in governance reform: the 2020 consolidation and the fund's relative transparency — it publishes annual results and geographic breakdowns that many Gulf peers do not — make it a useful reference point for how a mid-sized sovereign fund can professionalise.
It is a study in capital recycling: the divestment programme shows how a state investor can act as a seller as well as a buyer, using its balance sheet to develop domestic markets rather than crowd them out.
And it is a co-investment counterparty: as OIA pushes into AI, healthcare and energy-transition assets abroad, it increasingly shows up alongside larger sovereign funds, pension plans and private-markets managers in the same deals. For any universal owner mapping the Gulf capital landscape, OIA is a smaller but rising node in a network dominated by Abu Dhabi, Riyadh and Doha.
The bottom line
The Oman Investment Authority is a mid-sized sovereign wealth fund punching above its weight. Its roughly $60 billion in assets will not move global markets, but its dual-mandate structure, disciplined divestment programme and standout 2025 returns make it one of the more interesting smaller funds in the Gulf — and a reminder that in sovereign investing, governance and discipline can matter as much as scale.
