An OECD report released this spring warns that rapidly growing cities across Southeast Asia face a funding gap for green, resilient and inclusive urban development unless governments diversify financing instruments, strengthen subnational creditworthiness and crowd in private investment through targeted risk-sharing tools and project pipelines. The report, Financing Sustainable Cities in Southeast Asia: Diversifying Instruments and Leveraging Private Investment, focuses on the ASEAN‑5 — Indonesia, Malaysia, the Philippines, Thailand and Viet Nam — and argues that existing public budgets and traditional bank lending will not be enough to deliver mass transit, flood defences, clean water, affordable housing and low‑carbon energy at the speed cities need. The analysis, issued by the OECD and presented at regional events in April–May 2025, lays out practical steps for national and local policymakers to mobilise a broader mix of instruments — municipal bonds, green and sustainability bonds, blended finance facilities, public‑private partnerships with stronger safeguards, and value‑capture tools — while improving governance and transparency to make urban projects bankable for institutional investors (OECD report).

A groundbreaking OECD study released this spring delivers a stark warning that Southeast Asia’s rapidly expanding urban centers stand at a financial crossroads, with traditional funding mechanisms proving catastrophically inadequate for the green infrastructure revolution these cities desperately need. The comprehensive analysis, titled “Financing Sustainable Cities in Southeast Asia: Diversifying Instruments and Leveraging Private Investment,” focuses laser-sharp attention on the ASEAN-5 nations—Indonesia, Malaysia, the Philippines, Thailand, and Vietnam—revealing how conventional public budgets and standard banking relationships cannot possibly deliver the mass transit systems, flood protection networks, clean water infrastructure, affordable housing developments, and low-carbon energy installations these urban areas require at breakneck speed. International development experts who presented the OECD findings at high-level regional conferences throughout April and May 2025 outlined an ambitious roadmap requiring national and local policymakers to fundamentally restructure their approach to urban finance through innovative instruments including municipal bonds, green and sustainability-linked securities, sophisticated blended finance facilities, reformed public-private partnerships with enhanced social safeguards, and strategic value-capture mechanisms that improve governance transparency to make urban projects genuinely attractive to major institutional investors.
