Vietnam’s bond market has begun to emerge, demonstrating growing investor appetite for sustainable finance. However, issuances to date have remained concentrated in bank balance sheets and large-scale infrastructure projects, with limited relevance for distributed renewable energy. While these transactions signal positive market development, Vietnam’s capital market remains underdeveloped and have not yet become a reliable source of funding for small scale C&I scale rooftop solar developers such as Verdant Energy to get long-term debt that is suitable for C&I solar projects. Institutional investors remain cautious due to credit risks, limited project scale, and the absence of credit enhancements. Without innovative financing solutions, such as guaranteed bonds, the sector will struggle to attract the capital needed to scale. Addressing these financing gaps is essential to accelerate the energy transition and ensure long-term energy security.
