The article provides a theoretically grounded analysis of selected instances of legal interactions between bodies of norms emanating from formal and informal sources of regulatory authority in the issue area of global financial regulation. It discusses such interactions by looking at examples from global financial and accounting standards, credit rating agencies, banking and derivatives market regulation, anti-money laundering and terrorist financing standards. The focus is on relationships and tensions between different kinds of norms created by multiple regulatory networks and other private and public standard setters in the field of global governance of finance, characterised by transnational legal pluralism. Ultimately, the analysis seeks to shed light on the forms of legal interactions, between distancing and linkages of legal norms, and on the ways through which these interactions are dealt with in practice from the perspective of regulators and addressees of these norms.
