This paper examines the processes by which regulations prevailing in countries at the core of the global economy spread to countries outside this small group. The authors show how specific cross-border relationships between banks, regulators and investors generate regulatory interdependence that drives the diffusion of international standards from the standard-setting countries at the core of the financial system to the financial periphery. The authors argue that regulatory decisions in the financial periphery are shaped by the prior choices of regulators in other countries, mediated through four specific cross-border relationships associated with banking globalisation.

The paper draws on a new dataset of Basel II adoption in over 90 jurisdictions in the financial periphery. Using spatial lag models, the authors show that regulators’ decisions over the adoption of international standards are shaped by the choices of regulators to whom they are connected through the cross-border operations of individual banks, international professional networks and competition for capital. The authors' analysis underscores the value of parsing out the relevant actor-level linkages that connect countries; while international considerations shape regulatory decisions, what matters is not the extent to which countries are connected to the global economy but rather the nature of these connections.
