ASEAN has been through two major financial crises in the last quarter century: the 1997-98 Asian Financial Crisis (AFC) and the 2008-09 Global Financial Crisis (GFC). Although there is a voluminous literature covering the original five members, it has largely ignored the newer members – Brunei Darussalam, Cambodia, Lao PDR, Myanmar and Vietnam (BCLMV). For the first time, a systematic analysis of the experience of the newer members of ASEAN relating to the AFC and the GFC focusing on impact, policy response and lessons is provided. Their participation in regional financial cooperation initiatives in helping prevent or mitigate the impact of future crises, and how these initiatives need to be enhanced to better serve them is also considered.
