The creation of a European Banking Union and a European Energy Union have been two high-profile integration projects in a decade characterised by multiple crises. While recent research has focused on the direct effects of crisis on European integration dynamics, less attention has been paid to policy outcomes of market integration in sectors such as banking and energy. To address this gap, the study examines how distinct paths of integration, and the types of institutional change they involve, translate into patterns of sectoral governance. Further, it analyses the consequences of diverging patterns of sectoral governance for policy outcomes, examining whether the existence of supranational coordination bodies and public–private interaction is conducive to market integration. The findings from the analysis of the banking and electricity sectors suggest that while we see resilience and renewed integration in institutional terms, the change affecting policy outcomes appears to be more limited.
