Nathalie Ruiz, Head of Equity Sales, Continent & Global Buyside at Euronext, has been named winner of the Excellence in Equities category at the sixth edition of the 2025 European Women in Finance Awards, held by Markets Media Group at Claridge’s in London earlier this month. 

The award celebrates standout individuals who have demonstrated exceptional leadership and innovation across Europe’s financial markets. For Nathalie Ruiz, the recognition is not just a personal milestone, but also reflects the strength, growth and momentum of Euronext’s equities business across the continent. Following her win, we had the opportunity to hear from her about the achievements behind it and what continues to drive success in today’s equity markets. 

A year of growth, innovation and client partnerships 

“This recognition is a reflection of the exceptional collective work of our equities team,” Nathalie Ruiz said. “It demonstrates the confidence our clients have in us and the way we’ve positioned ourselves as trusted partners in today’s equity market.” 

Over the past year, Euronext has continued to strengthen its leadership in equities – both in trading and listings – through close integration across its local markets, a deep understanding of client needs, and strong collaboration between sales, product and research teams. 

One milestone was Euronext’s inclusion in the CAC 40^® index, a moment that Nathalie Ruiz described as a reflection of the strength and relevance of its equities business, along with steady client confidence. “It speaks to the trust clients and the market have in us, and how far we’ve come in building a unified, resilient equities offering across all our markets,” she said. 

Meeting the changing market head-on 

The equities market in 2025 looks markedly different from five or ten years ago, and expectations for service, insight and adaptability have risen sharply in return. 

“What sets us apart today,” Nathalie Ruiz explained, “is our ability to actively listen to our clients and rapidly adapt. The sales team works hand-in-hand across departments, especially with our product and quant teams, to turn feedback into tangible, data-backed solutions.” 

This ability to anticipate client needs, rather than simply react to them, has reinforced Euronext’s role as a strategic partner across the buy and sell sides. “Clients no longer want just a venue. They want partners who provide liquidity, insight and long-term value,” she added. 

A huge differentiator 

A core strength of Euronext’s equities offering lies in its in-house quant research team, which is one of the largest of any exchange group in Europe. This team provides clients with actionable data and market intelligence that supports everything from behavioural analysis to execution strategy. 

“Our quant team is a huge differentiator,” said Nathalie Ruiz. “They consistently deliver insight that our clients can use internally, whether it’s for navigating volatility or optimising trading decisions. That kind of value is what keeps partnerships strong.” 

This focus on research, innovation and partnership extends across Euronext’s markets, underlining the importance of understanding both where the market is today in addition to where it is heading.  

Leadership grounded in empowerment and purpose 

With over 15 years of experience in equities and two decades in financial services, Nathalie Ruiz brings both deep market knowledge and a collaborative leadership style. For her, leadership is about empowering others, driving innovation and staying grounded in client needs. 

“I’ve worked with incredibly talented people throughout my career — in investment banks, with retail brokers, and now at Euronext. This award is a recognition of all the teams I work with at Euronext and the work we’ve done together,” she said. “True leadership is about creating the conditions for your team to succeed, thinking creatively with clients to focus on their needs, and always keeping an eye on the bigger picture: how can we help shape the future of equity markets for the benefit of the entire financial ecosystem?” 

As Euronext continues to lead as Europe’s leading market infrastructure, Nathalie Ruiz’s recognition is a testament to its ambition in equities — one built on data, insight, client partnership and innovation. 

Europe is undergoing profound technological and geopolitical transformation. 
To remain competitive, it needs deeper, more integrated capital markets — and Euronext Securities is helping make that vision a reality.

In this video, Pierre Davoust, Head of Euronext Securities, shares our vision for a truly unified European post-trade landscape, our progress toward integration, and how we’re delivering added value to our clients.

Europe’s post-trade infrastructure is vital to the functioning of capital markets, but persistent fragmentation and inefficiencies continue to drive up costs for investors and limit the competitiveness of EU companies. Euronext Securities is moving decisively with a pan-European strategy that brings competitive choice, technological innovation and long-term scalability to the core of post-trade services. A recent economic report by Oxera Consulting LLP sponsored by Euronext has demonstrated why this approach is adapted to the current fragmented post-trade markets. The report sheds light on the challenges facing the EU’s post-trade infrastructure and the growing opportunity to drive down costs, boost efficiency and improve market resilience through smarter, interoperable infrastructure.  

An economic analysis of EU CSD services 

The report, titled The Design and Functioning of CSD Services in the EU, explores the structure of Central Securities Depository (CSD) services across the EU. It responds to a growing policy focus driven by the Draghi and Letta reports (2024) and the European Commission’s recent work on the need for further consolidation or integration of market infrastructures. The analysis assesses whether Europe’s current framework can deliver more competitive and efficient outcomes for issuers and investors. 

Fragmentation and missed opportunities 

The EU is home to over 30 CSDs, mostly defined by national boundaries. This fragmentation has long been seen as a source of inefficiency and complexity, particularly for cross-border trading and settlement. However, the report challenges the idea that the only path to improvement is full consolidation into a single EU-wide CSD. Instead, it argues that effective competition can be equally powerful if the right conditions are in place. 

Competition is an effective way to address fragmentation, provided all CSDs use T2S 

The report explains that economies of scale, scope and network effects are key drivers of efficiency in the Central Securities Depository (CSD) market. TARGET2-Securities (T2S), along with regulations such as CSDR and MiFID, has established the technical and legal foundations necessary to support competition. Importantly, the report emphasises that competition does not lead to fragmentation. As long as CSDs remain connected through platforms like T2S, network effects are maintained, and users can continue to access services seamlessly. 

What’s needed now 

While the foundations for competition exist, the report notes that effective issuer and settlement competition has yet to emerge. The lack of competitive pressure has contributed to persistently high costs, limited service innovation and slower market integration. The analysis concludes that the market is now at a critical juncture, and with the right strategic interventions, competitive dynamics could deliver meaningful benefits for all market participants. 

Turning analysis into action: Euronext’s strategic response 

Euronext Securities’ strategy is a credible and ambitious response to the challenges of Europe’s post-trade. It provides the benefits of both choice and consolidation to clients. 

The strategy is anchored in three priorities: 

• Offer market participants (trading firms, custodians, settlement agents, etc.) a single point of entry to European markets: Starting September 2026, clients will become able to consolidate settlement and custody for the Belgian, Dutch and French markets in Euronext Securities, alongside Italy, Denmark, Norway and Portugal. 

• Offer issuers the best access to Euronext, Europe’s single liquidity pool: By joining Euronext Securities, issuers can support the liquidity of their shares, broaden their investor base or simplify their journey on capital markets. Euronext offers a credible alternative for the first time, which it has already proven by migrating its own share issuance to Euronext Securities. 

• Deliver technology and service innovation: Euronext is rolling out a new, future-proof, harmonised CSD platform across all CSDs it operates, delivering a better, integrated client experience and value-added services to clients. 

Together, these steps are designed to enable true pan-European post-trade integration, delivering lower costs, greater operational efficiency and more competitive services. In doing so, the expansion project also contributes to strengthening the EU’s financial sovereignty and strategic autonomy by supporting a more resilient, interconnected and autonomous capital markets infrastructure.  

Choice against fragmentation 

Euronext is offering clients a choice that did not exist before: starting September 2026, for the first time in decades, clients will be able to manage multiple European markets (France, Belgium, the Netherlands, Italy) in one single CSD.  

Euronext is building an open model: Clients can use Euronext Securities’ offering even if they trade or clear on other trading and clearing venues. Conversely, Euronext trading members will have the possibility to settle at another CSD than Euronext Securities – provided the applicable regulatory framework (CSDR and MiFID) is respected. 

Euronext’s proposal fosters market integration, thanks to the use of Target2-Securities: T2S has been designed to allow settlement across multiple CSDs with no friction or extra cost. Hence, offering a choice of CSD (provided T2S is used), like Euronext offers, does not break the liquidity pool. It rather offers clients willing to do so the ability to consolidate European markets in one CSD. 

Leading the market towards integration 

As Pierre Davoust, Head of Euronext Securities, explains: “Europe’s post-trade should be completely integrated. Capital market participants should be able to manage their operations as if Europe was a single domestic market.” 

To advance this vision, Euronext is investing in modern, value-added services, from tailored data solutions to tax processing, with the launch of its European offering in September 2026. The hub will enable participants to manage post-trade activity across Belgium, France, Italy and the Netherlands from a single securities account, simplifying operations and enhancing scale. 

Shaping the future of capital markets 

The Oxera report highlights a clear opportunity: with the right strategic action, Europe can foster meaningful competition in post-trade services. Euronext Securities is acting on that opportunity by building on regulatory progress, infrastructure scalability and operational expertise to help reshape the European post-trade environment. As the EU continues its journey toward more integrated capital markets, Euronext Securities is helping ensure it does so with purpose, scale and resilience.
