The recent turn to market activism is transforming the politics around the state and capitalism, while significantly restructuring markets. We focus on one important but understudied element in this development: the securitization of market competition in the European Union. We argue that European political actors are strategically using specific narratives to construct competition policies in a new way, one that implicates the geopolitical standing of the EU and its national security. This contrasts with the longstanding view of EU competition policy as existing in a separate sphere, disembedded from politics, where market efficiency is paramount. To empirically capture this change, we undertake a systematic analysis of DG Competition Annual Reports, using a language-analysis schema over the decade from 2013 to 2023. Our findings demonstrate that this securitization strategy has been consistently increasing over time in the EU, evidenced in the rhetorical use of crises, the linking of markets to a larger set of issues and policy goals, the invocation of geopolitical pressures, and the framing of a need for the consolidation of EU power. We note, however, that this policy turn towards securitization of economic policy brings substantial political tensions given the EU’s limited democratic accountability.
