Indonesia Launches Sovereign Wealth Fund INA's $10 Billion Green Bond

Inaugural Tranche Oversubscribed

The Indonesia Investment Authority (INA), the country's sovereign wealth fund, launched a $10 billion green bond program on March 26, with the inaugural $3 billion tranche drawing orders totaling $12.6 billion — an oversubscription of 4.2 times. The bonds were issued in three tranches: $1 billion of 5-year notes at a yield of 5.15%, $1.2 billion of 10-year bonds at 5.65%, and $800 million of 20-year securities at 6.10%.

The issuance represents the largest green bond from a Southeast Asian sovereign entity and the largest from any emerging market sovereign wealth fund.

Use of Proceeds

INA will direct proceeds toward three categories of investments. Approximately 60% will fund renewable energy projects, including geothermal power plant expansion in Sumatra and Sulawesi, rooftop solar installation programs across industrial estates in Java, and floating solar farms on reservoirs in Kalimantan.

The remaining 40% will finance sustainable transportation (including electric bus procurement for 15 cities) and green building certification programs for government facilities. All projects must meet the Climate Bonds Initiative's green bond standard and will be subject to annual third-party verification by Sustainalytics.

Investor Base

The bond attracted a diverse international investor base. Asian institutional investors took 45% of the allocation, followed by European investors at 30% and Middle Eastern funds at 15%. Central banks and sovereign wealth funds accounted for approximately 35% of the total order book.

"This deal demonstrates that emerging market green bonds can attract genuine demand at competitive pricing," said Matthew Toole, director of deals intelligence at Refinitiv. "The 10-year tranche priced 25 basis points inside Indonesia's conventional sovereign curve, reflecting a measurable green premium."

Indonesia's Energy Transition

Indonesia has committed to achieving net-zero emissions by 2060 under its Long-Term Strategy submitted to the United Nations Framework Convention on Climate Change. The country currently relies on coal for approximately 62% of electricity generation, the highest coal dependence in Southeast Asia.

The Just Energy Transition Partnership (JETP), agreed with G7 nations in 2022, provides $20 billion in public and private financing to support Indonesia's coal phase-out. INA's green bond program is designed to complement JETP funding by mobilizing additional private capital.

INA's Growing Role

Since its establishment in 2021, INA has grown its assets under management to approximately $25 billion through a combination of government capital injections, co-investment partnerships with foreign sovereign funds, and now debt issuance. The fund has invested in toll roads, airports, telecommunications towers, and digital infrastructure across the archipelago.

INA has co-investment partnerships with Abu Dhabi Investment Authority, GIC, and the Japan Bank for International Cooperation, each of which has committed $2 billion to Indonesian infrastructure.

Market Significance

The green bond issuance signals Indonesia's growing sophistication in climate finance and its ability to access international capital markets at favorable terms. Southeast Asia's green and sustainable bond market reached $42 billion in cumulative issuance by end-2025, with Singapore, Thailand, and Indonesia as the largest contributors.

INA plans to issue the remaining $7 billion under the program in annual tranches through 2029, with each issuance aligned to specific energy transition milestones in Indonesia's national determined contribution under the Paris Agreement.
