The global financial crisis showed the need for a large-scale and effective international financial safety net (IFSN). Although East Asia has had a regional financial arrangement (RFA) since 2000 (the Chiang Mai Initiative1), it was not tapped during the global financial crisis for a variety of reasons. Our recent study examines the requirements for an effective IFSN. It should have adequate resources to deal with multiple crises, be capable of making a rapid and flexible response, and not be encumbered by historical impediments such as the IMF stigma that would limit its acceptance by recipient countries. Oversight of the IFSN needs to be based on cooperation between global and regional forums, for example, in the case of Asia, the G20 and ASEAN+3.
