Financing the In-between: Singapore’s Bold Push for Southeast Asia Transition Finance

Transition finance in Southeast Asia is expected to grow in 2026 as market participants gain clearer tools for how carbon-intensive sectors can use sustainability-labeled financing to decarbonise. The Loan Market Association published a guide on structuring transition loans aligned with net-zero pathways, and the International Capital Market Association released a tool for issuing transition bonds. HSBC’s Max Thomas said the guidelines are a “meaningful step forward” for Asian issuers, pointing to greater clarity on disclosures around transition strategy and a more holistic perspective for investors. For Singapore, that clarity matters because the region’s hardest-to-abate industries often struggle to access green financing that requires low-carbon baselines from day one.

The near-term backdrop helps explain the urgency. LSEG data cited by Singapore EDB shows sustainable finance proceeds raised in Southeast Asia remained flat in 2025 compared with 2024. ESG bond proceeds were US$20.3 billion in 2025 versus US$20.2 billion in 2024, while ESG loans slipped 0.8% year on year to US$43 billion from US$43.3 billion. Market watchers linked the environment to heightened risks and volatility, including tariffs imposed by the United States. This is where transition finance can fill an “in-between” gap: it gives emissions-intensive companies a structured way to finance change, rather than being excluded by criteria designed for already-green activities.

Why Singapore Is Building the Market Plumbing First

Singapore’s strategy is to make transition finance investable by improving rules, taxonomies, and risk-sharing structures. UNDP notes that Singapore has limited land and natural resources, but strong regulatory institutions, deep financial markets, and policy credibility, positioning it well in the climate transition. It also highlights the role of blended finance, where concessional capital can absorb early losses to mobilise private investment in underserved markets and sectors. Singapore has pioneered blended finance platforms such as the Financing Asia’s Sustainable Transition Partnership (FAST-P). The Singapore Sustainable Finance Association has also issued guidance on leveraging the Singapore-Asia Taxonomy for transition financing, and OCBC’s Jeong Yoonmee said refining taxonomies for real-world usability can help drive growth.

The scale of the region’s transition needs is repeatedly framed as an investment challenge, but also a project-design challenge. UNDP cites an International Energy Agency estimate that Southeast Asian countries will need to double annual investment to nearly US$30 billion by 2035 to integrate renewable energy at scale, while electricity demand in Southeast Asia has tripled over the past two decades. The Ecosperity Impact Report argues that the biggest sustainable finance challenge in Asia is not simply a lack of available capital, but difficulty creating projects that are commercially bankable, scalable, and attractive to institutional investors. That framing supports Singapore’s emphasis on blended finance structures and on platforms that align policy, capital, and implementation pathways.

Concrete platforms and deal flows help translate strategy into market depth. The Ecosperity Impact Report says the Financing Asia’s Transition (FAST) Conference convened more than 1,000 delegates from 640 organisations in 2025. It also highlights FAST-P, launched by the Monetary Authority of Singapore at COP28, which aims to mobilise up to US$5 billion for green and transition financing in Asia through concessional and commercial capital structures. Alongside this, BlackRock and Temasek’s Decarbonization Partners fund closed at US$1.4 billion in 2024 after attracting more than 30 institutional investors. Market participants will still watch how global taxonomies and standards are applied, as ING’s Martijn Hoogerwerf cautioned that misalignment across frameworks may constrain volumes even if issuance grows.
