Sovereign wealth funds (SWFs) have emerged as some of the most powerful financial entities of the modern world. With assets surpassing $12 trillion, they represent both a promise and a peril: a promise of stability, savings, and development, but also a peril of misuse, corruption, and political entanglement. While some countries have managed their SWFs with discipline, others have fallen victim to abuse, leaving behind cautionary tales. For the United States, the question of whether to establish such a fund has been raised in recent years, but the evidence suggests it is neither necessary nor prudent.
At their core, sovereign wealth funds are state-owned investment vehicles, financed typically from one of three main sources: revenues from natural resources such as oil and gas, excess foreign exchange reserves, or budgetary surpluses. Their defining feature is state ownership with the mandate to invest for the long term rather than to meet immediate fiscal needs. Most SWFs pursue one or more of three objectives: savings, stabilization, and development. Savings funds exist to transform temporary windfalls, often from exhaustible resources, into enduring wealth for future generations.
Stabilization funds are designed to smooth fiscal volatility, particularly in resource-dependent economies vulnerable to commodity price swings. Development funds seek to spur domestic economic growth, often by investing directly in infrastructure or strategic industries. Norway’s Government Pension Fund Global, for example, exemplifies the savings model, whereas Mexico’s Stabilization Fund aims to shield the budget from oil price volatility. The economic rationale underpinning SWFs is tied to the permanent income hypothesis. Resource-rich countries, recognizing the finite nature of commodities, attempt to convert temporary income into a diversified global portfolio that can generate perpetual returns. The interest and dividends from these investments can support government budgets, or be reinvested, ensuring intergenerational equity.
SWFs are not a monolith; they differ sharply in structure, funding, and purpose. Some, like Singapore’s Temasek, originated as vehicles to manage state-owned enterprises at arm’s length from the government. Others, like China’s funds, are tied to foreign exchange reserves accumulated from trade surpluses. Many in the Middle East are commodity-based, funded by oil and gas revenues. Operationally, they occupy a peculiar position between autonomy and accountability. While they are formally separate from fiscal and monetary authorities, their objectives often overlap with national development goals. This autonomy can sometimes be a strength, insulating investment decisions from short-term political pressures, but it can also open the door to policy misalignment or outright misuse.
Despite their potential, sovereign wealth funds have a checkered record. For every success story such as Norway, there are cases where funds have been depleted, mismanaged, or turned into instruments of patronage. One recurring problem has been the use of stabilization funds for fiscal bailouts that leave them drained during crises. Mexico’s stabilization fund, for instance, was nearly exhausted during the Covid-19 pandemic, declining by 94 percent by the end of 2020 . Similarly, some funds have suffered massive losses due to poor management or overexposure to risky markets. During the pandemic, global SWFs collectively lost an estimated $800 billion, or 16 percent of their asset value, underscoring their vulnerability to global shocks.
Corruption and political misuse have also plagued funds. In Angola, the Fundo Soberano de Angola (FSDEA), created in 2012 with $5 billion in oil revenues, was supposed to serve as both a savings and development vehicle. Instead, billions were siphoned off through questionable transactions linked to politically connected insiders. Even after making significant improvements on governance scorecards, the fund was exposed as being used for personal enrichment and political favoritism.
Malaysia’s 1MDB fund is perhaps the most notorious case of outright kleptocracy. Between 2009 and 2015, more than $4.5 billion was diverted through shell companies and offshore accounts, financing luxury real estate, private jets, and even Hollywood films such as The Wolf of Wall Street. At least $1 billion landed in the personal accounts of then–prime minister Najib Razak, revealing how an SWF without transparency can become the epicenter of one of the world’s largest corruption scandals (Sovereign Wealth Funds: Corruption and Other Governance Risks, pp. 45–48).
Other countries display different but equally troubling patterns. Equatorial Guinea’s sovereign wealth fund has virtually no public disclosures despite being endowed with oil revenues, while Turkey’s wealth fund has acted as a “parallel budget” for the president, bypassing parliamentary oversight and accumulating questionable assets. These examples demonstrate that the very qualities that make SWFs powerful also make them prone to abuse when governance institutions are weak.
The debate over whether the United States should establish a sovereign wealth fund resurfaced during the 2024 elections, when political figures suggested using such a fund to invest in strategic technologies or manage national wealth. However, the case against an American SWF is compelling.
First, the United States already possesses the most efficient and liquid capital markets in the world. Unlike resource-dependent economies that need to transform volatile rents into stable income, the U.S. has deep and diversified financial markets that serve the same purpose at a macro level. Private pension funds, mutual funds, and institutional investors already channel enormous sums into global investments, performing the intergenerational saving function more efficiently than a government fund could
Moreover, fiscal realities weigh heavily against the idea. With a national debt surpassing GDP and persistent budget deficits, the U.S. lacks the surpluses that typically fund SWFs. Establishing a national fund would require either additional taxation or borrowing, which would undermine its very rationale. In contrast to countries with excess reserves or commodity rents, the United States is structurally reliant on debt financing, making a sovereign wealth fund fiscally imprudent
Additionally, political divisions make the governance of such a fund nearly impossible. SWFs thrive on long-term horizons insulated from partisan cycles. In the U.S., however, the risk of political interference would be overwhelming. Parties would clash over investment mandates—whether to maximize returns, pursue social objectives, or fund strategic industries—resulting in a politicized and ineffective institution. The risk of the fund becoming a political slush pool would be unacceptably high.
Finally, the U.S. does not face the “resource curse” that motivates many SWFs. Nations dependent on commodities need mechanisms to stabilize revenues and ensure future wealth once resources are depleted. The United States, with its diversified economy and global currency status, has no such structural need
Sovereign wealth funds are fascinating institutions at the intersection of economics and politics. They embody a nation’s attempt to convert temporary or volatile wealth into enduring prosperity. In some cases, such as Norway or Singapore, they have done better than expected. But in many others, they have fallen prey to misuse, corruption, or fiscal desperation, leaving behind little more than cautionary tales.
For the United States, the evidence is clear. Its deep financial markets, fiscal position, and political climate render a sovereign wealth fund unnecessary and potentially dangerous. Rather than seeking to imitate commodity-dependent nations, America’s challenge lies in restoring fiscal discipline and managing its existing public finances. Sovereign wealth funds may serve as lifelines for some countries, but they are not a tool suited to the American context.
