Demystifying the Prudential Carve-out: A proposal

This article explores how the broadest spirited exception in the framework of the World Trade Organization, commonly referred to as the prudential carve-out, could be applied without adding to or diminishing the rights and obligations of WTO Members.

However, this broad standard of review can be enriched by expert knowledge on financial and prudential regulation, given that the form of dispute settlement established in the Annex to Financial Services of the GATS provides a window for dissecting the concept of “prudential”. The AFS requires that an “expert panel” decide on controversies regarding financial and prudential issues, instead of the ordinary “highly qualified” WTO panel.
