The aftermath of the 2007 subprime mortgage crisis indicates the need for transformation within the financial regulation market. To what extent will the 2004 Revised Framework on International Convergence of Capital Measurement and Capital Standards (Basel II) symbolize a watershed moment in the international effort toward regulatory convergence? Banking on Basel provides an assessment of the implications of Basel II and considers how the lack of a single national policy interest will influence the international dimension of these accords. The author offers a three-point analysis that evaluates domestic bank capital regulation (particularly, minimum capital requirements applicable to large banks) analyzes the dynamics of international coordination, and comparatively measures the alternatives and outcomes of implementation. Ultimately, the balance between regulatory models and the operation of the Basel committee will determine the far-reaching ramifications of Basel II.
