Sovereign wealth funds have become some of the most powerful players in global finance. They now manage more than US$16 trillion in total assets, up from about US$3 trillion in 2008.
Their ability to act nimbly, diversify public wealth, and invest for the long-term have important and lasting benefits for citizens today and future generations.
As funds have grown, their mandates have rapidly expanded beyond cushioning government budgets and stewarding intergenerational savings to roles as diverse as building infrastructure and implementing social and industrial policy.
Increasing geopolitical fragmentation has intensified the appeal of these funds as countries seek to be more self-reliant.
Funds can boost domestic resilience, preserve national wealth, advance national development objectives, and foster economic dynamism. With projects spanning private equity, real estate, and technology, they have become some of the world’s most influential investors.
While these funds are key players in managing public funds, their massive and complex footprint could pose critical vulnerabilities.
Vague and overlapping mandates can weaken accountability and weigh on performance. Weak governance can allow misappropriation, as shown by the high-profile failures of some funds.
Funds operating as parallel fiscal authorities and bond buyers without clear fiscal anchoring may risk distorting government budgets, obscuring public debts, and complicating tax treatment cross-border.
Looking across borders, funds partnering on projects concentrate their risk exposures, making a shock to one investor a risk to all.
National objectives may also diverge, for instance one partner prioritizes domestic job creation while another focuses on financial returns, weakening governance and investor credibility. And if relations among partner countries sour, it can be difficult to protect assets or exit a project.
These vulnerabilities can be mitigated, however, through strong laws. Internationally accepted guidelines and practices such as the Santiago Principles, developed in 2008 by 26 funds with IMF support, have served as a valuable guide.
However, as funds have grown significantly in size, complexity and diversity since then, it is important to examine more closely how funds are structured and governed.
Commodity exporters, for instance, prioritize short-term fiscal stabilization, as shown by Chile’s Economic and Social Stabilization Fund.
Wealthier economies focus on long-term savings, as seen with Norway’s Government Pension Fund Global, the New Zealand Superannuation Fund, and the Future Ireland Fund.
The Indonesia Investment Authority, meanwhile, demonstrates how emerging and developing economies tend to emphasize development objectives, including economic diversification. In some circumstances, multiple objectives may be warranted. In historically oil-dependent economies such as the United Arab Emirates, wealth funds may combine stabilization and economic diversification roles.
For Singapore’s two funds, by contrast, the overriding objective is long-term savings, with Temasek supporting strategic sectors and domestic economic development, while GIC invests internationally.
Pursuing multiple mandates, however, can involve difficult tradeoffs. Clear purpose is essential for guiding fund managers while preserving each mandate’s binding force.
Overly broad mandates with multiple and potentially conflicting objectives in a single fund can create risks. Risks are heightened when mandates expand without corresponding governance and oversight adjustments.
Legal separation—whether through separate funds or clearly segregated sub-funds—is often a better way to pursue different mandates while ensuring clarity and operational coherence.
The Nigeria Sovereign Investment Authority provides a clear example, with its stabilization, future generations, and infrastructure funds legally ring‑fenced. Norway, meanwhile, operates a single fund as a long-term savings vehicle, investing exclusively abroad with a strong legal framework.
Its stabilization function is achieved through the fiscal framework, which limits annual budget transfers to expected returns on the fund.
Once the legal form is fit for purpose, the next step is grounding governance in law with statutory allocation of powers, enforceable fiduciary duties, transparent reporting, and effective oversight.
As wealth funds move into more complex direct and unlisted investments, governing bodies must be legally empowered to exercise informed, independent supervision of partnerships and transactions.
Laws requiring that board members have a balanced set of skills and expertise, institutionalized audit and risk management, and robust internal control functions act together to ensure good governance. -IMF
