ASEAN regional financial integration evolves within four domains: the banking sector, liberalizing foreign direct investments, liberalizing capital flows, and ensuring regional financial stability. Progress so far has been limited. Regional integration as concerns the liberalization of capital markets and, in particular, the banking sector, proceeds with the most difficulty. By most criteria, ASEAN is well positioned to benefit from deeper financial integration. Comparative analysis also demonstrates that there is a substantial 'learning factor' in this technically complicated field: while ASEAN learns about the EU, the Eurasian Union is taking a close look at ASEAN's experience of integration of the financial markets.
