Integrated Supervision as a Pillar of European Capital Markets

In the journey towards deepening and integrating the European Union’s capital markets, a crucial aspect remains the supervisory dimension, which is currently identified as a significant missing link in the integration agenda. The Savings and Investments Union (SIU) aims to efficiently mobilize Europe’s substantial savings, enhance investment and innovative efforts, fortify cross-border risk-sharing, and ultimately, boost the EU’s overall economic resilience and competitiveness. However, despite strides toward regulatory harmonization, the actual results concerning market integration, depth, and scale have not attained the expected levels of success.

A Fragmented Supervisory Landscape

In Europe, we can recognize six fundamental archetypal supervisory models that govern the financial markets, five of which are actively operational, albeit often in mixed configurations. These models encompass everything from fully integrated supervisors responsible for banking, securities, and insurance sectors (either within or external to central banks) to segmented arrangements with distinct authorities managing each financial sector. Moreover, there are objective-based models, known as “twin-peaks,” that clearly delineate duties between prudential and conduct supervision. Consequently, the complexity of the EU’s supervisory landscape consists of 16 uniquely structured institutional setups, each impacted by historical developments and incremental reforms that have emerged in the wake of financial crises.

Financial sector supervision is dispersed among 52 national authorities, leading to a highly fragmented environment. This proliferation causes notable discrepancies in mandates, supervisory practices, and enforcement outcomes. Even where EU legislation dictates uniform legal obligations, the degree to which these mandates are actualized diverges from one jurisdiction to another, influenced by distinct interpretations and local supervisory cultures. Despite the existence of a regulatory framework, considerable fragmentation persists, ultimately culminating in non-uniform supervisory outcomes across various jurisdictions.

The Role of EU-Level Oversight

At the European level, the European Securities and Markets Authority (ESMA) plays a role in rulemaking and fostering supervisory convergence; however, this authority directly supervises merely a limited cohort of entities. The majority of capital market participants continue to fall under the aegis of national supervision, revealing a longstanding division of responsibilities that maintains the status quo of national borders, despite prevalent cross-border activities.

When compared to other advanced jurisdictions, such as the United States, the EU’s supervisory framework appears even more dispersed. In the U.S., capital market supervision is predominantly federal, with major authorities like the Securities and Exchange Commission and the Commodity Futures Trading Commission overseeing securities and derivatives markets, supplemented by state bodies and self-regulatory organizations. On the other hand, Europe’s system is characterized by a multifaceted stratification of responsibilities lacking any direct equivalent in the U.S., which underscores the necessity for a re-evaluation of supervisory structures to enhance effectiveness.

A Case for EU-Level Supervision

There are compelling reasons why EU-level supervision is vital. Firstly, it would bolster supervisory efficiency by aligning oversight with the inherent cross-border nature of capital market risks. A unified supervisory body would provide the capacity to conduct comprehensive risk assessments, thereby enhancing the identification and handling of risks throughout the financial ecosystem.

Secondly, integrated supervision would optimize efficiency by consolidating expertise and reducing redundancy. This consolidation would enable better resource allocation, particularly in swiftly changing sectors characterized by scant expertise—ultimately streamlining supervisory interactions and reinforcing the overall efficacy of oversight.

Thirdly, the implementation of EU-level supervision would lead to simplification across the board, for both supervised entities and supervisory bodies alike. A common supervisory methodology would streamline processes and improve consistency while also lowering compliance costs for cross-border enterprises.

Finally, the necessity for EU-level supervision emerges as a foundational element for advancing capital market integration under the Savings and Investments Union. It ensures the consistent application of EU regulations, helps dismantle supervisory barriers, and provides a level playing field instrumental for economic consolidation, which is paramount for unlocking the EU capital markets’ potential.

The Need for Reform

To bolster EU-level supervision represents a feasible and effective tool for furthering the objectives of the Savings and Investments Union, while simultaneously enriching harmonization efforts. Though legislative alignment may be necessary to support market integration, efforts towards these reforms tend to be politically intricate and challenging. In contrast, supervisory integration can yield meaningful outcomes in a relatively shorter timeframe. The integration of supervision stands not as a substitute for legal harmonization but as a critical complement capable of reducing fragmentation and harnessing the full capability of the EU’s capital markets to mobilize savings and support seamless investments across the Union.
