Across the ASEAN+3 region,  which includes Southeast Asia, China, Japan, and South Korea, governments and businesses are increasingly embracing sustainable finance to help meet ambitious climate goals. With global climate finance needing to reach $9 trillion by 2030, and Asia-Pacific requiring an estimated $2 trillion annually to align with the Paris Agreement, the pressure to mobilize capital is mounting.

But accessing this funding, especially in emerging and frontier markets, remains a major challenge. This is where the Credit Guarantee and Investment Facility (CGIF), a trust fund of the Asian Development Bank (ADB), plays a critical role. By offering credit guarantees on sustainable bond issuances, CGIF reduces investment risks, helping unlock local currency bond markets and attract more investors to environmental, social, and governance (ESG) projects.

Bridging Gaps in Sustainable Finance

The ASEAN+3 region faces a dual challenge: Growing demand for sustainable infrastructure and energy projects, and a need to climate-proof economies against extreme weather events. However, capital mobilization is often slowed by perceived risks, ranging from regulatory uncertainty to credit concerns.

CGIF addresses this by providing unconditional guarantees that cover both principal and interest payments in the event of a default. This de-risking mechanism helps improve the creditworthiness of sustainable bonds, often upgrading them to investment-grade level thanks to CGIF’s AA rating by S&P.

Making Sustainable Bonds More Attractive

CGIF’s guarantees deliver several benefits:

• Improved credit ratings: Bonds backed by CGIF are more likely to attract institutional investors such as pension funds and insurance firms, who often require investment-grade assets.
• Boosted investor confidence: CGIF involvement signals that the project has undergone stringent due diligence and adheres to international sustainability standards.

Market development: Supporting early-stage issuances helps create a track record for sustainable finance in local markets, encouraging more issuers and investors to join in.

Real-World Impact: Powering Clean Energy and More

CGIF’s growing portfolio of green and sustainable bonds is already making a difference.

In March 2025, it supported Cambodia’s first green and partially guaranteed project bond, issued by SchneiTec Dynamic to fund a solar power project. This milestone attracted both local and international investors to a frontier market.

In January 2025, CGIF guaranteed its first-ever blue bond, issued by China Water Affairs to finance sustainable water management infrastructure.

In 2024, CGIF backed several sustainability-linked bonds (SLBs):

• Sabana Industrial REIT’s SLB in Singapore
• PT Steel Pipe Industry’s SLB in Indonesia (issued in Rupiah)
• Thailand’s first SLB in the shipping sector by Precious Shipping Public Company

Each project contributes to decarbonization, job creation, and local economic growth.

Championing Standards and Partnerships

CGIF is also helping to build an enabling environment for sustainable finance. As a key partner in the Cambodian Sustainable Bond Accelerator Program, it collaborates with global and regional institutions like the UNESCAP and GuarantCo to develop robust sustainability frameworks.

This push for standardization is critical in making sustainable bonds more credible and attractive to global capital providers.

The Future

Scaling up sustainable finance is both an environmental necessity and an economic opportunity. CGIF plans to continue innovating its guarantee products and building partnerships to unlock even greater flows of capital into renewable energy, green infrastructure, and climate-resilient projects.

As CGIF prepares to speak at the Sustainable Debt Asia 2025 conference in Singapore, its message is clear: Credit guarantees are a powerful catalyst for sustainable development in the ASEAN+3 region. By reducing risk and building investor trust, CGIF is helping to transform the region’s financial systems, one bond at a time.
