In December 2021, the Asian Development Bank and the Global Green Growth Institute conducted an online survey and received a total of nine responses from institutional investors and underwriters in the Lao People’s Democratic Republic (Lao PDR). Given the size and current stage of capital market development in the Lao PDR, the number of responses provides us with a good indication of the interest of local market participants. The survey was conducted to assess institutional investors’ interest in green bonds issued in the Lao PDR, as well as the perspectives of local underwriters on their clients’ interest in green bond issuance. The survey identified the market drivers, impediments, and development priorities to assist development partners in identifying potential areas of support to accelerate the development of the Lao PDR’s sustainable finance market.
