In 1953, eight years before Kuwait even became an independent nation, Sheikh Abdullah Al-Salem Al-Sabah set up an investment office in the City of London with a simple mandate: take oil revenue and turn it into something that would last longer than the oil itself.[s] That decision created the world’s first sovereign wealth fundA state-owned investment fund that manages national savings or commodity revenues on behalf of a government, typically for long-term economic benefit.. Today, more than 100 sovereign wealth funds control nearly $15 trillion in global assets, and the countries that pioneered the model remain its most powerful practitioners.[s]
What Sovereign Wealth Funds Actually Do
A sovereign wealth fund is a state-owned investment vehicle, typically funded by commodity revenues or trade surpluses, that invests in assets around the world. Norway’s Government Pension Fund Global, the largest single fund at over $2 trillion, owns roughly 1.5 percent of every listed company on the planet, with stakes in approximately 7,200 firms.[s] Norway discovered oil in the North Sea in 1969, passed legislation creating the fund in 1990, and deposited its first transfer in 1996.[s] The idea was that oil revenue should benefit future generations, not just the current one.
The Gulf states operate on a different logic. Five funds from Saudi Arabia, the UAE, and Qatar, collectively known as the “Oil Five,” accounted for 61 percent of all sovereign wealth fund investment globally in 2024, deploying some $180.3 billion.[s] Middle Eastern sovereign wealth funds now hold more than $5.6 trillion in assets under managementThe total market value of investments that a financial institution manages on behalf of clients., a sum that would make them collectively the third-largest economy in the world.[s]
From Savings Accounts to Power Players
For most of their history, sovereign wealth funds were conservative. Gulf states parked surplus oil revenue in U.S. Treasury bonds and other low-risk assets, recycling petrodollarsUS dollars earned by oil-exporting countries through petroleum sales, typically reinvested in global financial markets. back into the American financial system. That began changing in the early 2000s when oil prices surged and government savings rates in the Gulf climbed to around 40 percent.[s]
The surplus was too large for bonds alone. Sovereign wealth funds began buying stakes in companies, real estate portfolios, and infrastructure projects. Saudi Arabia’s Public Investment Fund, once an obscure domestic vehicle, was transformed in 2015 into a modern investment powerhouse. It now holds roughly 76 percent of its assets in the Saudi domestic economy, funding Vision 2030 projects, while simultaneously holding significant stakes in international companies like Uber and Lucid Motors.[s]
The 2008 financial crisis marked a turning point. When Western banks were hemorrhaging capital, several sovereign wealth funds stepped in with billions in emergency liquidityCash or readily convertible assets made available to financial institutions during market crises to prevent system collapse..[s] That rescue earned these funds both gratitude and wariness; it demonstrated that state-backed capital from oil-producing nations had become structurally important to the global financial system.
Where the Money Is Flowing Now
The latest frontier is artificial intelligence. In early 2026, OpenAI sought investments from Middle Eastern sovereign wealth funds for a funding round expected to total around $50 billion.[s] Gulf sovereign wealth funds have also invested in renewable energy, hydrogen infrastructure, and critical mineralsRaw materials essential for economic security and national defense, often subject to supply chain vulnerabilities., positioning themselves at the center of the global energy transition.[s]
In the first nine months of 2025, Middle Eastern sovereign investors accounted for 40 percent of all state-investor deal value worldwide, with transactions totaling $56.3 billion.[s] These sovereign wealth funds take equity stakes that are 2 to 3 percent larger than comparable institutional investors, particularly in sectors aligned with national strategic priorities.[s]
Why This Matters
When a government owns a piece of your country’s critical infrastructure, the relationship between investor and investee is different from a private transaction. Jared Cohen and George Lee of Goldman Sachs have described this as “instrumental capitalState-directed funds used to pursue dual mandate of generating financial returns and projecting state power.,” defined as “the use of state-directed funds to pursue the dual mandate of generating financial returns and projecting state power.”[s]
Political economist Kathryn Lavelle put it more bluntly: “for most SWFs, it remains deeply unclear who is actually making the investment decisions and for what purposes.”[s] The managers insist they operate on purely financial logic. But they ultimately answer to heads of state.
The consequences can be dramatic. When Singapore’s sovereign wealth fund Temasek acquired a stake in Thailand’s telecommunications sector, the backlash from Thai citizens over foreign ownership of their communications infrastructure contributed to the dissolution of the Thai government in 2006 and a subsequent coup d’état.[s]
What Comes Next
GCC sovereign wealth funds currently control $4.9 trillion in assets and are projected to reach $18 trillion by 2030.[s] Middle Eastern sovereign wealth funds alone could reach $8.8 trillion by the same date.[s] The model that Kuwait invented in 1953 has become a permanent feature of global finance, and the oil states that built it show no sign of relinquishing their position.
In February 1953, Kuwait’s Sheikh Abdullah Al-Salem Al-Sabah established the Kuwait Investment Board in the City of London, creating what is now recognized as the world’s first sovereign wealth fundA state-owned investment fund that manages national savings or commodity revenues on behalf of a government, typically for long-term economic benefit..[s] The original mandate was narrow: invest surplus oil revenue abroad to reduce dependence on a finite resource. More than seven decades later, sovereign wealth funds collectively manage just under $15 trillion in global assets, and the five most active funds, all based in the Gulf, account for 61 percent of total sovereign investment volume.[s]
Institutional Architecture of Sovereign Wealth Funds
The Gulf’s dominant sovereign wealth funds, referred to by analysts as the “Oil Five,” are Saudi Arabia’s Public Investment Fund (PIF), Qatar’s Investment Authority (QIA), and the UAE’s Abu Dhabi Investment Authority (ADIA), Mubadala, and ADQ. In 2024, all five ranked among the world’s ten most active sovereign wealth funds for the third consecutive year, deploying a combined $180.3 billion, with total assets of approximately $3.5 trillion.[s]
Stephan Roll of the German Institute for International and Security Affairs (SWP) argues these funds serve a dual function: converting oil revenues into diversified investment capital while simultaneously expanding the foreign policy capabilities of their home states. “Institutional and personnel linkages enable the Saudi, Qatari and UAE governments to deploy their funds strategically,” Roll writes, enabling them “to significantly expand their hard, soft, and sharp power.”[s]
Political economist Kathryn Lavelle of Case Western Reserve University identifies a fundamental tension within all sovereign wealth funds: “a core contest takes place between the state’s interests (or sovereign) part of the dynamic, and the money interests (or wealth) part of it, and these two aspects are frequently in contradiction, serving fundamentally different goals.”[s]
The Three Dimensions of Sovereign Wealth Funds as Power
The SWP framework maps Gulf sovereign wealth fund activity across three power dimensions. Hard power comes through investments in defense and strategic sectors. Soft powerThe ability to influence others through attraction and persuasion rather than coercion or economic pressure. operates through high-profile acquisitions in media, sports, and technology that reshape perceptions of the investing state. Sharp power involves leveraging investment relationships with politically influential actors to shape policy outcomes in host countries. The funds “do not function as direct instruments of foreign policy,” according to Roll’s analysis. “Rather, they increase the respective country’s scope for external action.”[s]
Norway’s Government Pension Fund Global represents the contrasting model. Established in 1990 after the 1969 North Sea oil discovery, the fund now exceeds $2 trillion and holds stakes in approximately 7,200 companies, owning nearly 1.5 percent of all global listed equities.[s] Norway operates under a fiscal rule limiting annual government spending to the estimated real return on the fund (approximately 3 percent), a mechanism designed to prevent the fund’s capital base from eroding. Lavelle notes that Norwegian domestic politics actively shapes fund behavior: “the SWF doesn’t invest in nuclear weapons or tobacco because of social concerns, but there is a continuing debate over whether it should invest in oil, even though that’s where most of the money comes from.”[s]
The Santiago Principles and the Transparency Problem
The 2008 Santiago Principles were developed by the International Working Group of Sovereign Wealth Funds with IMF support to establish transparency and governance standards. ADIA, Mubadala, QIA, and PIF all signed on.[s] In the same year, Abu Dhabi published an open letter in The Wall Street Journal asserting it had “never used sovereign wealth funds as instruments of foreign policy, nor would it do so in future.”[s]
In practice, compliance has been difficult to measure. Lavelle describes the core problem: “The biggest stumbling block was that there wasn’t exactly a good way to measure compliance with the Principles, let alone how to hold funds to them. If you read the Principles, they’re overall quite vague.”[s] Funds have a financial incentive to keep investment strategy proprietary, and the Principles offer no enforcement mechanism to override that incentive.
The Gulf funds have further obscured the political dimensions of their investments by channeling foreign acquisitions through private equity vehicles and subsidiaries.[s] This makes it exceptionally difficult for host-country regulators to assess whether a given investment serves commercial or strategic purposes.
Sovereign Wealth Funds in the AI and Energy Transition
Two sectors now concentrate Gulf SWF strategic interest. In artificial intelligence, OpenAI sought investments from Middle Eastern sovereign wealth funds for a funding round expected to total approximately $50 billion in early 2026, with CEO Sam Altman traveling to the UAE for investment discussions.[s] Sovereign wealth funds take equity stakes 2 to 3 percent larger than comparable institutional investors in sectors aligned with national strategic priorities, according to analysis from the Berkeley Political Review.[s]
In energy, Gulf sovereign wealth funds have repositioned as what the Observer Research Foundation calls “system-shaping institutions,” absorbing “first-mover risks in commercially immature sectors” to “de-risk the transition for private investors, accelerate project pipelines, and create investable ecosystems aligned with national diversification and global climate objectives.”[s]
Saudi Arabia’s PIF illustrates the dual domestic-international strategy. As of 2023, approximately 76 percent of PIF’s assets were invested inside Saudi Arabia, funding Vision 2030 diversification projects. Simultaneously, it held significant stakes in international firms including Uber and Lucid Motors.[s]
National Security Implications and Investment Screening
The political risks of sovereign wealth fund investments are not theoretical. When Singapore’s Temasek acquired a stake in Thailand’s telecommunications sector, public backlash over foreign state ownership of communications infrastructure escalated into a political crisis that “led to the dissolution of the entire Thai government in 2006 and a subsequent coup d’état,” according to Lavelle.[s]
The SWP report identifies specific risks for European recipients of Gulf capital: “third parties gaining access to critical infrastructure, sensitive military and security technology being leaked and the Gulf monarchies exercising political influence.” It warns that technologies acquired through sovereign wealth fund investments could be “transferred to third countries such as China and Russia.”[s]
Governments have responded by expanding foreign investment review mechanisms. The U.S. Committee on Foreign Investment (CFIUSCommittee on Foreign Investment in the United States, a government body that reviews foreign acquisitions of US companies for national security implications.) has broadened its oversight of acquisitions involving critical technologies, and similar frameworks have emerged across Europe, Japan, and Australia.[s]
Scale Projections and Strategic Outlook
In the first nine months of 2025, Middle Eastern sovereign investors accounted for 40 percent of global state-investor deal value, with deals totaling $56.3 billion.[s] GCC sovereign wealth funds currently control $4.9 trillion, representing 38 percent of global SWF assets, and are projected to reach $18 trillion by 2030.[s] Middle Eastern sovereign wealth funds more broadly could hold $8.8 trillion by the same date.[s]
Jared Cohen and George Lee of Goldman Sachs frame this as “instrumental capitalState-directed funds used to pursue dual mandate of generating financial returns and projecting state power.: the use of state-directed funds to pursue the dual mandate of generating financial returns and projecting state power.”[s] Whether host countries treat these sovereign wealth funds as welcome investors or potential security threats will depend on how effectively investment screening regimes can distinguish commercial from strategic intent, a distinction the funds themselves work to obscure.
