The Geoeconomics of the Single Market for Financial Services

We discuss the geoeconomics of the Single Market in financial services in the European Union (EU). We examine three case studies that concern the EU and other major jurisdictions and that range from incipient geoeconomic use to outward weaponisation of the Single Market in finance. These cases are (1) the post-2008 crisis transatlantic tug of war, whereby the EU leveraged its Single Market vis-à-vis the United States, seeking to set the rules for global finance; (2) the Brexit negotiations, when the EU acted as a bloc against the United Kingdom and successfully safeguarded the integrity of the Single Market; and (3) the fulsome war in Ukraine, during which the EU ‘weaponised’ its Single Market through the adoption of financial sanctions against Russia. We argue that a combination of external and internal factors accounts for this pattern: the evolution of the international economic and political system, in particular, the increasing challenges to the liberal international order, and intra-EU developments, namely, the EU's ability to deploy its Single Market geoeconomically.
