This article• Contributes to the debate on policy change and economic ideas after the crisis, finding ideas and material interests to be closely aligned and introducing the notion of 'ideational adverse selection'. • Establishes that pre-crisis financial governance failed to provide financial stability yet provided benefits to precisely those whose advocacy underpinned its emergence. • Argues that despite the adoption of a 'macroprudential approach', the post-crisis reform of financial governance promulgated by the Basel Commitee and IOSCO does not (yet) admit of a 'paradigm shift'. • Concludes that if ideational change and a shift in policy approach is to take place, the nature of the policy community as 'input' must also change.
This article focuses on two cases of transnational financial governance that confirm that ideas and material interests are closely aligned in the construction of regulatory institutions at the international level: the Basel-II/III international capital adequacy standards and the IOSCO-based regulatory processes that underpin cross-border securities markets.The article first establishes that the pre-crisis system of financial regulation and supervision left public authorities dependent on private sector expertise and information provision such that policy idea-sets became increasingly aligned with private sector preferences. Secondly, this market-based system of financial governance provided benefits to precisely those whose advocacy underpinned its emergence while facilitating neither financial stability nor resolving the weaknesses of national-level governance in a context of crossborder integration. Lastly, it remains unclear if either pre-crisis alternatives or the lessons of the crisis itself have been applied properly to the reforms. The reform debate continues to pursue an essentially market-based approach to the problem of financial governance at the national, regional and global levels. Policy failure endogenous to a pre-crisis regulatory coalition has so far failed to disturb the tenacity of material interests and inertia of institutional path dependency.This article focuses on the post-crisis financial reform process at the global level and assesses the extent and nature of the changes that have taken place. This analysis is framed by the debate about the role of ideas in post-crisis policy change, the theme of this special section of the British Journal of Politics and International Relations.The pre-crisis global financial system was characterised by a system of 'marketbased' financial governance resting on 'soft law' mechanisms (Brummer 2012) across national, regional, and global levels and that significantly enhanced the role bs_bs_banner According to the 'punctuated equilibrium' model of ideas and the policy process, the combination of the pre-crisis evidence plus the enormous shock beginning in 2007-08 should have proven a clear alibi for a 'third order' paradigm shift in the policy approach (Hall 1993). Blyth (2013) elaborates further on the conditions for a third-order...
