Operational coordination between Lead Overseers

Article 34 addresses the coordination challenge that arises when a single critical ICT third-party service provider serves financial entities supervised by different ESAs. A major cloud provider, for example, may simultaneously support banks (supervised by the EBA), insurers (supervised by EIOPA), and investment firms (supervised by ESMA). Without coordination, each ESA could issue inconsistent or contradictory oversight requirements, creating confusion and inefficiency for both the provider and the financial entities it serves.

The article mandates that Lead Overseers coordinate their oversight activities to ensure consistency. Where a critical provider is subject to oversight by multiple Lead Overseers, they must develop joint approaches to assessments, align their recommendations, and share findings. This coordination prevents the provider from receiving conflicting instructions — for instance, one ESA requiring a particular security standard while another requires a different approach.

Coordinated workplans are essential for minimizing the administrative burden on critical providers. Rather than subjecting a provider to separate, overlapping assessment cycles from multiple ESAs, the article encourages joint inspections, shared questionnaires, and unified timelines. This efficiency is important because excessive supervisory burden could paradoxically undermine a provider's operational performance.

From a practical standpoint, financial entities should monitor the coordination between their regulators regarding shared critical providers. Inconsistent regulatory expectations for the same provider can create downstream compliance uncertainties for the financial entities that depend on it. The Joint Committee of the ESAs serves as the natural forum for resolving coordination challenges that cannot be addressed bilaterally between Lead Overseers.
