Temasek is a commercial investment company that owns stakes in operating businesses and acts as an active shareholder; its Net Portfolio Value was S$434 billion as of March 2025. GIC is a long-horizon reserves manager tasked with preserving and growing Singapore's official foreign reserves; it managed approximately US$936 billion as of March 2025. Temasek can own domestic Singapore companies; GIC invests exclusively outside Singapore.
Answer
Temasek is a commercial investment company that owns stakes in operating businesses and acts as an active shareholder. GIC is a long-horizon reserves manager whose sole mandate is to preserve and grow Singapore's official foreign reserves. Both are wholly owned by Singapore's Ministry of Finance, but they serve fundamentally different purposes, invest in different geographies, and are measured by different performance benchmarks.
What Is Temasek?
Temasek Holdings was incorporated in 1974 to hold and manage Singapore's government-owned commercial assets. From its origins managing state enterprises — Singapore Airlines, DBS, PSA — Temasek has evolved into a global investor active across financial services, telecoms, technology, consumer, life sciences, and real assets.
As of 31 March 2025, Temasek's Net Portfolio Value (NPV) stood at S$434 billion, up S$45 billion from a year earlier. On a mark-to-market basis, including an uplift for the unlisted portfolio, the figure was S$469 billion. About 51% of the portfolio was in liquid and listed assets; the remaining 49% was in unlisted assets and funds.
Singapore-based Temasek Portfolio Companies — DBS, Singapore Telecommunications, Keppel, and others — accounted for 41% of portfolio value. The rest is spread across Asia, the Americas, Europe and the Middle East.
Temasek as an Active Owner
Unlike a passive index fund, Temasek takes meaningful ownership stakes and engages with portfolio companies on strategy, governance and sustainability. It often provides patient capital through market cycles that pure financial investors cannot match. It also co-invests alongside global private equity firms and has a growing direct private equity capability in growth and venture.
Temasek's 20-year Total Shareholder Return of 7% per annum (as of March 2025) benchmarks well against comparable long-horizon investors. Its private portfolio has compounded at above 10% per annum over two decades, reflecting the illiquidity premium Temasek has captured through its ownership model.
What Is GIC?
GIC — the Government of Singapore Investment Corporation — was established in 1981 to manage Singapore's foreign reserves, separating the reserve management function from the Monetary Authority of Singapore (MAS), which oversees monetary policy and the exchange rate.
GIC's mandate is specific: preserve and enhance the international purchasing power of Singapore's reserves. Because this is a real-return mandate measured in global purchasing power terms, GIC's primary performance metric is the rolling 20-year annualised real rate of return. For the 20-year period ending March 2025, that figure was 3.8% per annum (5.7% USD nominal; 5.0% over 10 years; 6.1% over five years).
GIC does not publicly disclose its exact AUM. External estimates — including from the Sovereign Wealth Fund Institute and Global SWF — put the portfolio at approximately US$936 billion as of March 2025, making it one of the five largest sovereign wealth funds in the world. That figure is roughly double Temasek's NPV.
GIC's Portfolio Composition
GIC's asset allocation as of its 2024/25 annual report was: equities 51%, fixed income 26%, real assets 23%. Geographically, the Americas accounted for 49% of the portfolio (up from 44%), reflecting strong US equity performance, while Asia-Pacific fell to 24%.
Unlike Temasek, GIC invests exclusively outside Singapore. Investing domestically would risk inflating local asset prices, crowding out private capital, and creating a conflict of interest between GIC's investment decisions and Singapore's broader economic policy.

Why the Distinction Matters for Asset Owners
Institutional investors encounter both Temasek and GIC as counterparts — in co-investments, secondaries, infrastructure transactions, and direct deals. Understanding which vehicle they are working with matters:
Temasek as a co-investor: Temasek's commercial mandate and long investment horizon make it an attractive co-investment partner. It can hold illiquid positions for extended periods and bring operational knowledge of Asian markets. In recent years Temasek has been active in growth equity, climate-transition infrastructure and digital financial services across Southeast Asia and India.
GIC as a counterpart: GIC is one of the world's largest real estate investors and has deep exposure to private equity through its multi-manager and direct programs. Its real-return mandate makes it a particularly natural partner on infrastructure and real assets that offer inflation linkage and long-duration cash flows.
Both investors have also become reference points in discussions about how state-owned capital can be structured to avoid domestic market distortions — a governance model other sovereigns have studied and sometimes adapted.
Common Misconceptions
"They are competing funds": Temasek and GIC have complementary mandates and distinct investable universes. They are not duplicates. MAS also manages a third pool of Singapore reserves for monetary policy purposes.
"GIC is a sovereign wealth fund": Technically GIC's mandate is reserves management, not wealth accumulation from commodity revenues — the original definition of a sovereign wealth fund under the Santiago Principles. That said, GIC is commonly grouped with SWFs in institutional databases because of its size, state ownership and long-horizon strategy.
"Temasek is a passive holding company": Temasek actively engages with portfolio companies, deploys capital into new private markets strategies, and manages a growing sustainability and innovation agenda. It is far more dynamic than a static holding entity.
The Singapore State Investment Ecosystem
Singapore operates what amounts to a three-pillar state investment structure:
- MAS manages the foreign reserves needed for monetary policy (exchange-rate intervention, short-duration liquidity) — the most conservative, liquid tranche.
- GIC manages the long-duration tranche of official reserves across global multi-asset portfolios, seeking to preserve purchasing power over decades.
- Temasek manages Singapore's commercial equity stakes, operating as an active owner of businesses across Asia and globally.
Together, the three manage a combined pool that — based on public and estimated figures — likely exceeds US$1.5 trillion, making Singapore one of the most sophisticated state-capital systems relative to GDP in the world.
For institutional investors, the distinction between these three pools — their mandates, time horizons, risk tolerances and investable universes — is worth understanding precisely, because each presents different co-investment dynamics and different criteria for evaluating deal partners.
