Regulatory change across Europe is accelerating, but clarity is not keeping pace. For financial institutions managing third-party risk, the result is a growing tension between expanding compliance obligations and persistent ambiguity around how those obligations should be implemented in practice.

At the center of this challenge is the evolving framework of EU regulation, including initiatives such as the Digital Operational Resilience Act and broader supervisory expectations around outsourcing, critical third parties, and operational resilience.

While these frameworks aim to strengthen financial stability, they also introduce new layers of interpretation risk, particularly for third-party risk management (TPRM) functions.

Institutions are no longer simply expected to demonstrate that they have vendor risk frameworks in place.

They are now required to show that those frameworks are effective under stress, integrated across the organization, and capable of adapting to emerging risks such as cyber threats, geopolitical disruption, and concentration risk within vendor ecosystems.

However, the practical application of these requirements remains uneven. One of the most pressing issues facing TPRM teams is the lack of consistent definitions. What constitutes a ‘critical’ or ‘important’ third party can vary across jurisdictions and regulators.

This creates a moving target for firms operating across multiple EU markets, forcing them to interpret guidance in ways that are defensible but not always aligned.

This ambiguity is particularly challenging in the context of vendor classification and risk tiering. Firms must make judgment calls on which vendors fall into the highest-risk categories, yet those decisions can later be second-guessed by supervisors.

As a result, many institutions are adopting increasingly conservative approaches, expanding the scope of what they classify as critical to avoid regulatory scrutiny.

The unintended consequence is operational strain. Over-classification can dilute focus, stretching resources across too many vendors and reducing the effectiveness of deep risk assessment where it is most needed.

In attempting to comply with regulatory expectations, firms risk creating complexity that undermines their ability to manage risk in a meaningful way.

At the same time, regulators are placing greater emphasis on evidence. It is no longer sufficient to document policies and procedures. Institutions must demonstrate how risks are identified, monitored, and mitigated in real time.

This includes providing clear audit trails, testing resilience under adverse scenarios, and showing how third-party dependencies are managed during disruptions.

This shift toward evidence-based supervision is reshaping the role of TPRM. Functions that were once primarily compliance-driven are becoming central to operational resilience strategies.
