DMA Regulatory Interplays

  • February 25, 2026
Share.
Read the Issue Paper "DMA Regulatory Interplays"

As the Digital Markets Act enters its implementation phase, its interaction with the other pieces of the Digital rulebook – such as the GDPR or the DSA – or more horizontal EU law, such as competition law and IP, is becoming increasingly consequential. Without clearer co-ordination, regulatory overlaps risk creating legal uncertainty, conflicting remedies, and higher compliance costs.

In this Issue Paper, CERRE Academic Director Alexandre de Streel and Research Fellow Giorgio Monti set out concrete recommendations to strengthen coherence across the EU digital framework:

  • Adopt practical joint guidance to manage overlaps between instruments, clarify proportionality standards, and specify where safe harbours apply.
  • Operationalise the parallel application of the DMA and GDPR by developing clear co-operation workflows, increasing transparency around compliance expectations, and ensuring that guidance remains proportionate and legally grounded.
  • Reduce regulatory fragmentation through stronger institutional coordination, targeted legislative simplification, and an evidence-based ‘digital fitness check’ of the DMA. EU-level solutions should be prioritised for cross-border conduct.

Together, these recommendations aim to reduce legal uncertainty, lower compliance burdens, and reinforce the effectiveness and legitimacy of the EU’s digital regulatory architecture.

The research was presented on 25 February 2026 at the Digital Platforms Summit 2026.
