Will ESMA Become Europe's SEC? Ross on Governance

In brief: The European Union is moving to turn the European Securities and Markets Authority (ESMA) into a central supervisor of large parts of its capital markets, a model often compared to the US SEC. In an interview with Bloomberg on 27 October 2026, outgoing ESMA chair Verena Ross said the reform's success depends less on the scope of new powers than on the governance that lets the regulator act quickly and consistently. Institutions raising or deploying capital across the bloc should watch how decisions get made, not just who holds the mandate.

The argument running through Europe's supervisory overhaul is simple to state and hard to execute: a single rulebook is worth little without a single hand to apply it. For two decades the EU has written common capital markets rules while leaving enforcement to twenty-seven national authorities, producing a market that is integrated on paper and fragmented in practice. The reform now in motion tries to close that gap by giving ESMA direct supervisory authority over the market's most systemic infrastructure. Ross's warning, delivered as she prepares to leave office, is that the design of ESMA's internal decision-making will determine whether the change delivers.

What is the EU's plan to centralize market supervision?

The plan is called the Market Integration and Supervision Package (MISP), published by the European Commission on 4 December 2025. It is the supervisory engine of the broader Savings and Investments Union, the 2025 strategy that rebranded and widened the long-running Capital Markets Union. The package bundles two proposed regulations and one proposed directive, and it amends 19 separate pieces of EU legislation in a single move, according to Baker McKenzie's analysis.

At its core, MISP would make ESMA the direct supervisor of the market's load-bearing structures rather than a coordinator sitting above national regulators. As Bird and Bird noted, ESMA would undergo a fundamental transformation to become the EU's central financial supervisor. The entities in scope include significant central counterparties, central securities depositories, the largest trading venues, and all crypto-asset service providers. Smaller firms and less significant clearing houses would stay under national oversight, a deliberately tiered design meant to concentrate EU-level attention on systemic risk.

The comparison to the US Securities and Exchange Commission is the shorthand everyone reaches for, and it captures the ambition. It also overstates the reality. The SEC is a single federal regulator with broad direct jurisdiction; the European model remains a hybrid in which ESMA supervises the systemic core while national competent authorities retain most day-to-day work. Ross herself put the distance plainly, telling Bloomberg it is unlikely ESMA will match the SEC's scope in her lifetime.

Why does governance decide whether the reform works?

Here the argument sharpens. Transferring powers to a central body is the visible part of the reform; deciding how that body actually decides is the part that determines outcomes. Ross's message is that a regulator can hold sweeping authority and still fail if its internal machinery is slow, consensus-bound, or captured by the twenty-seven competing national interests it is meant to rise above.

That is why the least discussed clause of MISP may be the most consequential. The package would replace ESMA's existing Management Board with a new Executive Board of independent, full-time members empowered to take supervisory decisions, as Bird and Bird set out. The shift matters because supervision is a continuous function. A board of permanent officials accountable to the EU interest can act within days; a body of national representatives negotiating positions tends to move at the speed of its slowest member. Ross framed the prize as a "turbo-charged" ESMA able to decide quickly and consistently across the bloc, and the governance architecture is what makes that speed possible or impossible.

The European Central Bank has pushed in the same direction, arguing for a stronger ESMA to close the supervisory gap with the United States. The intellectual case for consolidation is now broadly shared among EU institutions. The open question is execution, and execution lives in the governance text.

How does this follow from the push for European competitiveness?

The reform does not appear in a vacuum. It is the operational answer to a diagnosis made forcefully in 2024 by the Draghi report on European competitiveness, which argued that fragmented capital markets starve European companies of scale financing and leave the continent reliant on bank lending and foreign investors. A market split across twenty-seven supervisory regimes imposes duplication, legal uncertainty, and cost on any issuer or asset manager trying to operate continent-wide.

The logic connecting the dots is direct. If Europe wants deeper pools of investable capital, it needs instruments and infrastructure that behave the same way in Frankfurt, Paris, and Dublin. Programmable and composable financial products only compound that need, because an instrument designed to move and settle across borders is worth far less if each jurisdiction supervises it differently. Consistent, auditable supervision is not a bureaucratic nicety in that world; it is the precondition for the single market the Savings and Investments Union is trying to build. The Council of the EU agreed key elements of its negotiating position in October 2026, moving the file from proposal toward law.

What does the handover at ESMA signal?

The timing is pointed. ESMA is changing its leadership at the exact moment its mandate is being rewritten. Ross, who took the chair on 1 November 2021 after serving as the authority's first executive director, announced in December 2025 that she would not seek a second term and would leave at the end of October 2026. Carlo Comporti, confirmed by the Council on 9 October 2026, took over on 1 November, inheriting both the expanded powers and the governance debate that will shape them.

Ross has been consistent that the destination is not a wholesale seizure of authority from national regulators. In her October 2026 keynote at the European Capital Markets Dialogue, she described effective supervision as a "joint undertaking" between ESMA and national competent authorities, paired with simplification and outcome-focused rules. That framing matters for institutions reading the tea leaves: the model being built is centralized at the systemic core and cooperative at the edges, and the governance rules decide where exactly that line falls and how firmly it holds.

What institutions should take from this

The single thing that matters most is governance, not scope. The headline that ESMA may become a European SEC tells capital markets participants less than they think, because the powers on paper are only as useful as the body wielding them is fast and consistent. An issuer weighing where to list, a clearing house assessing its future supervisor, or an asset manager pricing cross-border compliance should read the Executive Board provisions and the national-versus-EU split before the marketing language. That is where predictability will be won or lost.

For institutions building or raising against programmable, composable, and auditable assets, the stakes are concrete. Consistent EU-level supervision would mean one supervisory relationship for systemic infrastructure instead of many, clearer rules for instruments that settle across borders, and a more credible single market to raise capital into. Those are the conditions in which composable instruments and transparent, auditable structures move from promise to practical infrastructure. The reform's ambition is real, but as Ross made clear on her way out, the details of how ESMA decides will determine whether it earns the comparison it is already being given.
