This paper defines SIFs as special purpose investment funds that exhibit all of the following six characteristics. These funds: 

  • Are sponsored and/or fully or partly capitalized by a government, by several governments, or by government-owned global or regional finance institutions; 
  • Invest to achieve financial as well as economic returns, in accordance with a double bottom line; 
  • Aim to crowd in private capital by co-investing at the fund and/or project level; 
  • Operate as expert investors on behalf of their sponsors;
  • Provide long-term patient capital, primarily as equity, and may also invest in quasi-equity or debt; and 
  • Are established as investment funds or investment corporations.

Appendix A contains a non-exhaustive list of SIFs categorized according to their geographical scope. 

SIFs come in different flavors. Their investments tend to focus on infrastructure projects and/or funds, but may also include investments in private equity (PE) and venture capital (VC) funds for small and medium enterprises (SMEs). A useful categorization of SIFs can be derived from research carried out by Clark and Monk (2015) on sovereign development funds, which the authors define as publicly sponsored commercial investment funds that combine financial performance objectives with development objectives. The authors suggest four operational and not mutually exclusive strategies for sovereign development funds: (i) reinforcing, by reorganizing, professionalizing, and innovating state holdings (companies, infrastructure, or other real assets) so as to drive commercialization and higher returns; (ii) crowding in private capital, by acting as a cornerstone investor in key sectors or projects; (iii) catalyzing, by seeding new industries, thereby diversifying the economy away from industries that are no longer profitable or sustainable over the long term; and (iv) financializing, by deepening local financial markets, thereby underwriting the development process through the growth of the capital market and the emergence of new financial intermediaries and investors focused on opportunities in the region. Each of these strategies is situated along a double spectrum, from strategic to commercial in terms of investment objectives, and in tight or loose alignment with national endowments and advantages (figure 1).

Figure 1. Categorization of Strategic Development Funds


Because SIFs are first and foremost commercially oriented investors focused on leveraging public investment by crowding in new sources of funding from the private sector (either domestic or foreign), by definition they populate the upper-right quadrant in figure 1. Within this operating environment, SIFs could be categorized on the basis of their policy objectives as mainly catalytic, or reinforcing, or financializing. Figure 2 applies the proposed taxonomy to a subset of SIFs. The graph helps to visualize SIFs' strategic positioning, and suggests that financializing and reinforcing are the most common strategies for the SIFs observed in this paper, particularly in emerging markets and developing economies (EMDEs). On the other hand, SIFs that focus on climate financing appear to play a catalytic role independent of the country of operation. Examples include the Africa Renewable Energy Fund (AREF), the Renewable Energy Asia Fund (REAF), and the Global Energy Efficiency and Renewable Energy Fund (GEEREF).

Figure 2. The Strategic Positioning of Sovereign Investment Funds


As with sovereign wealth funds (SWFs), SIFs' sources of funding may include balance-of-payment surpluses, official foreign currency operations, the proceeds of privatization, pension reserve funds, fiscal surpluses, government (or government guaranteed) borrowing, and/or receipts resulting from commodity exports (IFSWF 2009). However, monetary authorities' foreign reserves held for balance-of-payment purposes, government employees' pension funds, traditional public enterprise operations, and assets managed for the benefit of individuals are not sources of funding for SWFs and SIFs. 

International, bilateral or multilateral financial institutions, domestic development banks, and some commercially focused development and climate finance institutions are not SIFs. Although these institutions may fulfill the four criteria proposed above, they differ from SIFs in their governance structure, and/or investment policy, deal sourcing, and staffing. In all these respects, they are more akin to government institutions than to SIFs, which – as discussed further in this paper – are nimbler structures that derive much of their modus operandi from the PE model. For example, South Africa's Public Investment Corporation is a state-owned asset manager that invests on behalf of the Government Employees Pension Fund (89 percent), Unemployment Insurance Fund (6 percent), and other public funds. Its main investment objective is to achieve strong long-term capital returns above the clients' benchmark while contributing to the broader social and economic development of South Africa and the rest of the African continent. The Public Investment Corporation lacks a formal double bottom line and, being a pension fund manager, is not an SWF, as defined by the International Monetary Fund (IMF) and the International Forum of Sovereign Wealth Funds (IFSWF). By the same line of reasoning, pension funds are not SIFs even when they align with responsible investment principles (consider, for example, the California Public Employees' Retirement System, CalPERS, which is the largest pension fund in the United States). 

Public pension funds derive at least part of their resources from contributions made by employees, and their fiduciary responsibility is toward their contributors. Specifically, for a defined contribution scheme, the fiduciary obligation is to maximize the replacement value of pensions provided to members upon their retirement. For this reason, pension funds' investments are entirely commercial and cannot be subject to a double bottom line – though they can and do invest in SIFs on commercial terms (for example, the South African Government Employee Pension Fund has invested in the Pan-African Infrastructure Development Fund). Unlike public pension funds, pension reserve funds are generally capitalized by budget transfers. Their objective is to hold precautionary savings for future government expenditures, which may include public pensions without having any contractual obligations to future pensioners (IMF 2008). Pension reserve funds function very much like other long-term government savings funds. Some pension reserve funds, such as Australia's Future Fund and the Ireland Strategic Investment Fund (ISIF), have combined commercial and developmental objectives. These particular reserve funds are SIFs. Others, such as the New Zealand Superannuation Fund, invest on purely commercial terms and are not SIFs. 

Government-owned investment funds that are fully capitalized by the government or a subnational entity to serve a politically defined purpose, and that do not seek private capital participation at the fund or project level, are also not SIFs. These funds represent pools of public capital destined for public investment, often in infrastructure, that could in principle be implemented through the normal budget process. They are fiscal funds: essentially, quasi-fiscal tools for governments. Like SIFs, fiscal funds provide increased functionality to public investment, since managerial and professional capacity is centralized in a specialized body. Their singular focus on policy objectives makes the attainment of these objectives more straightforward than for SIFs. But it also may cut them off from sources of private capital since profitability is a critical factor in attracting private investors. A notable example is the State Oil Fund of the Republic of Azerbaijan, which lists among its objectives "financing major national scale projects to support socioeconomic progress". 

SWFs may exhibit some of the characteristics of SIFs, particularly if their domestic investment strategy involves a double bottom line (for example, Malaysia's Kazanah Nasional Berhad, and the Nigeria Infrastructure Fund owned by the Nigeria Sovereign Investment Authority). However, unlike SIFs, SWFs' international investments are usually guided by commercial principles only. That said, an SWF with an exclusively domestic investment mandate may be considered an SIF if it exhibits the six characteristics listed in section 2 of this paper. 

SIFs support the development of local economies through direct investment that aims to generate a high level of private sector participation. To achieve their objectives, SIFs use different approaches: some domestically focused SIFs are owned by both the public and the private sector, while others are wholly owned by a government; some SIFs operate at a global or regional scale, and may be funded by several governments. For example, the Philippine Investment Alliance for Infrastructure (PINAI) is a 10-year closed SIF, managed by a specialized private investment manager – Macquarie Infrastructure Management (Asia) Pty Limited – that invests exclusively domestically in a broad range of infrastructure projects. The PINAI was created in 2012 by the Government of the Philippines with assistance from the Asian Development Bank (ADB), and has a domestic and a foreign pension fund as the two largest shareholders. Senegal's Fonds Souverain d'Investissements Stratégiques (FONSIS) also invests only domestically. It was established in 2013 to catalyze external investment supporting the development of a strong local economy and the creation of jobs. However, its capital structure is much simpler than the PINAI: it is wholly owned by the Government of Senegal, and operates as a private equity firm on the government's behalf. As a result, its investment strategy is closely guided by the government's national development plan. The European Fund for Strategic Investments (EFSI) is a regional SIF. It was established in 2015 and is funded through a €16 billion first-loss guarantee facility provided by the European Commission (EC) and by €5 billion capital provided by the European Investment Bank (EIB) – the European Union's long-term public lending institution. The fund is managed by the EIB and aims to generate additional investment of €60 billion by the EIB and by the European Investment Fund (EIF) and to unlock at least €315 billion in private sector investment over a three-year period.3 Box 1 outlines PINAI, FONSIS, and EFSI in more detail. 

Box 1. Examples of Strategic Investment Fund Strategies: PINAI, FONSIS, and EFSI

The Philippine Investment Alliance for Infrastructure (PINAI) is a $625 million 10-year closed-end privateequity-type fund. The fund is managed by an external, private sector manager, Macquarie Infrastructure and Real Assets, and its policy objectives include (i) attracting top-tier international partners to infrastructure investments in the Philippines, (ii) fostering competition in domestic infrastructure finance, and (iii) establishing a secondary market for well-performing infrastructure assets.

The Philippine government asked the Asian Development Bank (ADB) to develop financing solutions to help meet its infrastructure gap. ADB's support for PINAI was built on previous legislative and fiscal reforms (for example, public-private partnership reforms, institutions, and feed-in tariffs).

PINAI is an alliance of a small number of parties that combine domestic knowledge and international experience:

  • The Philippines' Government Service Insurance System Fund (GSIS) is a large domestic social security fund intending to invest in domestic infrastructure, but with little or no experience in infrastructure investment. GSIS holds 64 percent of PINAI's assets.
  • The Netherlands' Algemene Pensioen Groep is Europe's largest pension fund, and has significant experience in direct and indirect infrastructure investment. It holds 24 percent of PINAI's assets.
  • The ADB provides guidance on the concept, design, and implementation of the new fund vehicle and holds 4 percent of PINAI's assets.
  • Macquarie Infrastructure and Real Assets is an experienced international fund manager holding 8 percent of PINAI's assets. It manages PINAI and is responsible for all major investment, divestment, and management decisions within the fund's overall mandate.

PINAI aims to provide equity and quasi-equity (mezzanine debt) financing in core infrastructure assets exclusively in the Philippines. It seeks to invest in a portfolio of greenfield and brownfield projects across a broad range of infrastructure sectors (including power, transport, and telecommunications), and has a cap on greenfield exposure. Information on PINAI's financial performance is not publicly available. However, GSIS was reported to have expressed an interest in doubling its investment in infrastructure projects in the Philippines to $800 million, on account of the very good returns and risk diversification offered by PINAI (interview with GSIS president Robert Vergara, The Philippine Star, February 7, 2016). PINAI's financial performance will need to be judged at the end of the 10-year term of the closed-end fund.

Senegal's Fonds Souverain d'Investissements Stratégiques (FONSIS) is a strategic investment fund focused on attracting private investment to Senegal by operating as a private equity investor on behalf of the government. Established in 2013, it aims to invest in projects that stimulate economic growth and job creation in the framework of the national development plan – Plan Sénégal Emergent – while creating wealth for current and future generations. Its stated policy objectives include the support of strategic economic sectors, sustainable jobs, and small and medium enterprises, as well as the optimization and management of state-owned assets.

FONSIS acts as a financial intermediary, which brings credibility; access to a network of international investors; and capacity to structure, negotiate, and transact deals. The fund has a minimum rate of return on its investments (hurdle rate) of 12 percent and a target multiplier of 1:12.4 Its investment criteria have been extensively disseminated in the national press, to build legitimacy and mitigate pressure to undertake projects that do not fit these criteria. FONSIS may – if necessary to attract external capital to high-priority projects – use a return margin that exceeds the hurdle rate to enhance returns or mitigate risk for external investors. Also, exceptionally and subject to board approval, it may cross-subsidize one project (whose expected returns are below the hurdle rate but which has significant positive externalities) from a project with higher returns, so that the joint expected returns remain above the hurdle rate.

The European Fund for Strategic Investments (EFSI) started operation in 2015. The fund aims to help overcome the financing gap in Europe by mobilizing private finance for strategic investments, and acts as one of the three main pillars of the Investment Plan for Europe. With EFSI support, the European Investment Bank (EIB) group provides funding for economically viable projects where it adds value, including projects with a higher risk profile than ordinary EIB activities. Further, EFSI aims to strengthen the European regulatory environment and support the investment environment throughout Europe.

EFSI priorities include:

  • Strategic infrastructure, including in the information technology, transport, and energy sectors
  • Education, research, development, and innovation
  • Expansion of renewable energy and resource efficiency
  • Support for small and medium enterprises Given its objectives, EFSI's main measure of success is the amount of external investment unlocked by its guarantees for investment in the fund's defined priority sectors. EFSI aims for a 1:15 multiplier on its investments for the aggregate investments generated. As of April 2016, EFSI approved 249 transactions in 26 of the 28 EU countries.


SIFs may also act as VC funds. The first state-sponsored VC fund programs were created by the U.S. and U.K. governments to improve financing for fast-growing young firms and foment post–World War II productivity. In the 1960s these funds represented the bulk of VC raised in the United States. Some of these programs are still functioning. For example, the Small Business Investment Company (SBIC) program, established in 1958, consists of federally guaranteed risk capital pools. State-sponsored VC programs are now seen in a growing number of EMDEs. In Senegal, Teranga Capital is an equity impact investment fund launched in 2016. The fund targets promising domestic SMEs, with financing needs between €75,000 and €300,000. In addition to long-term finance in the form of minority equity participation, Teranga Capital provides management coaching to support the growth and consolidation of the SMEs in its portfolio (sales and marketing; accounting; and environmental, social, and governance benchmarking). FONSIS invested in Teranga Capital as a limited partner alongside Investisseurs and Partenaires (the general partner and fund manager), Sonatel, Askia Assurances, and two private professional investors. Another SIF, the African Agricultural Capital Fund (AACF), provides growth financing to Africa's undercapitalized agriculture sector through SME investments in East Africa. The AACF was created in 2011 by the United States Agency for International Development (USAID) and another six investors. Managed by Pearl Capital Partners, the AACF aims to invest $25 million through equity investments to smallholder farmers with a target of around 15 percent annual compounded return. Successful VC industries have also been seeded by the governments of Israel and Brazil (box 2). 

Box 2. Venture Capital Funds in Israel and Brazil

Israel's Yozma program, established in 1993 with $100 million capital, initially sought to attract experienced international venture investors, who had to come up with $12 million of their own capital and work in partnership with an Israeli firm. Yozma would provide such investors $8 million in matching investments, with a capped upside to further attract private investors. Factors contributing to the program's success include that (i) its capital was spread across many small funds, (ii) it fostered relationships between local and international venture capitalists, and (iii) business incubators and tax incentives were established to complement the program. In the two decades after Yozma was established, Israel went from having no venture capital (VC) sector at all to having the highest VC penetration in the world as a share of gross domestic product (GDP), reaching 0.36 percent in 2012.

Brazil's Inovar program combines the role of VC co-investor with the provision of extensive capacity building. Inovar was launched in 2000 to teach entrepreneurs how to raise funds and to work with equity-holding partners. Limited partners learn how to evaluate funds, and general partners how to select companies, manage funds, assess investment opportunities, and manage portfolio companies. A special organizational framework and tax incentives have been put in place. In the beginning, Inovar's sponsored VC funds needed to raise only 20 percent from private investors as market validation, with the rest provided by the government as loans with a capped return. The Inovar model has since been exported to other Latin American countries. In 2014, the program managed a $197 million VC portfolio.


SIFs may also be thematic investors. Particularly in clean-energy finance, several SIFs have been established with the objective of attracting private investment in wind, solar, and thermal energy infrastructure; and energy efficiency. Some climate-focused SIFs are funded by multilateral financial institutions, including Asia Climate Partners (established by the ADB) and the GEEREF (a hybrid fund with both private and public shareholding established by the EIB and several European governments) (box 3). Green SIFs are emerging at the national level, too. For example, Norway recently announced its intention to establish a domestically focused renewable energy investment fund, Fornybar AS, and the Government of China is considering the establishment of a national green investment fund.

Box 3. Examples of Green Strategic Investment Funds

The Asia Climate Partners (ACP) is a $400 million joint initiative of the Asian Development Bank (ADB), the financial services group ORIX, and the asset manager Robeco. ACP makes private equity investments in the environmental industries, resource efficiency, and renewable energy sectors in Asia. Besides private equity, ACP provides additional forms of capital such as debt and credit enhancement from the ADB, climate finance facilities, and commercial debt from partner organizations.

The Global Energy Efficiency and Renewable Energy Fund (GEEREF) is an international fund-of-funds, domiciled in Luxembourg, which deploys public sector funds to catalyze private sector investment in clean energy projects. GEEREF started in 2008 with €112 million from the European Union, Germany, and Norway, and has since been further capitalized with an additional €110 million from private investors. GEEREF's investments aim to achieve a "triple bottom line": provide access to sustainable energy, combat climate change, and deliver compelling financial returns. Its target is to catalyze investments sufficient to generate 1 gigawatt of clean energy capacity, thereby avoiding 2 million tons of carbon dioxide emissions and potentially supporting the energy needs of 3 million people.
