This guide provides comprehensive information on Mongolia's local currency bond market. Since 2002, the Asian Development Bank has been working closely with the Association of Southeast Asian Nations (ASEAN) and Japan, the People's Republic of China, and the Republic of Korea-collectively known as ASEAN+3-under the Asian Bond Markets Initiative to develop resilient regional financial systems. Mongolia became an official observer of the ASEAN+3 Bond Market Forum in 2019 and has been an active participant since then. This guide aims to contribute to a better understanding of Mongolia's local currency bond market and facilitate its further development.
