East Asian financial regionalism has advanced significantly since the rejection of Japan's Asian Monetary Fund proposal in 1997. Key ASEAN+3 initiatives include the Chiang Mai Initiative, which is designed to provide emergency liquidity to economies experiencing currency crisis, and the Asian Bond Market Initiative, which seeks to develop regional bond markets. Surprisingly, these initiatives—despite the assertive “regionalist” rhetoric that has surrounded them and their intellectual origins in the analysis of the 1997–1998 Asian financial crisis—are explicitly designed to complement existing features of the global financial architecture, including IMF conditionality and global financial standards. The nesting of East Asian financial regionalism within the global financial architecture results from the political-economic interests of the leading economies of the region. In the absence of a major change in the political-economic environment, nesting is a stable equilibrium and is unlikely to change.
