Background & Biography
Queiroz works at the intersection of technology delivery and the business of financial-market infrastructure. Euroclear’s official biography assigns him responsibility for client experience and digital activity across business and technology, with data and innovation supporting that mandate. Its September–October 2026 Sibos roster continues to identify him as Chief Digital Officer. His public professional profile associates the Euroclear position with Brussels, providing the basis for Belgium as this profile’s professional market rather than an assumption about nationality or residence.
His earlier career combined entrepreneurship with a range of banking technology roles. Euroclear records more than a decade at BNP Paribas, including responsibility for distribution, service models and digital banking, alongside a deputy leadership position in international retail banking and SME activities. As CIO of Cortal Consors, he oversaw IT teams building Hello bank! in Germany; other responsibilities covered web and mobile services, business development and digital coordination. Before that banking career, he created technology businesses, and Euroclear identifies him as a founder of the recipe platform Ptitchef. The sequence matters because his digital-assets work grew out of broader service and operating-model transformation.
A 2021 interview in Square’s report on agile working offers a more specific account of his management approach. Queiroz described responsibility for Euroclear’s Agile centre and a role linking technology leadership with business priorities. He favoured adapting methods to the institution’s circumstances and consolidating practical capability before extending them further. Those are historical statements, not a description of today’s organization chart. They nevertheless show that his contribution involves changing how teams select and deliver work, as well as adopting new technical tools.
Notable Contributions
Queiroz was a named executive voice in the launch of Euroclear’s Digital Financial Market Infrastructure, or D-FMI. In Capgemini’s November 2023 account, he placed the programme within Euroclear’s wider strategy and discussed the intended improvements to securities processing and access to information. Capgemini separately identified itself as lead systems integrator, covering design, implementation, testing and connection to existing infrastructure. This establishes a documented strategic role for Queiroz while preserving the contributions of the delivery teams and external partners. The evidence documents his communication of the programme’s strategic purpose, rather than a claim that he personally designed the platform.
The programme had a concrete transaction behind it. The World Bank confirmed that its International Bank for Reconstruction and Development issued EUR100 million of three-year Digitally Native Notes on Euroclear’s new platform in October 2023. The issue settled on October 23 and used English-law securities. Euroclear’s infrastructure supported digital creation, issuance and primary distribution, with subsequent access to its traditional settlement environment. This is an example of an executed securities transaction, rather than an announcement of a prospective tokenisation experiment.
The World Bank’s accompanying case study clarifies the architecture and limits of that achievement. D-FMI used a private, permissioned implementation of R3 Corda for issuance and primary distribution. Settlement between the issuer and dealer took place on a delivery-versus-payment basis, and the notes then became available through Euroclear Bank for secondary-market transfers. The design connected a new ledger to established securities arrangements. It therefore provides evidence of institutional integration, without implying unrestricted public-chain trading or the replacement of every existing intermediary.
His work also extends to operational collaboration outside blockchain systems. Taskize’s December 2025 review identified Queiroz as its board chair and described his participation in the company’s year-end discussion. That review reported use of Taskize by Euroclear Bank’s collateral-management operation and the launch of EasyFocus+, developed with Euroclear and Meritsoft to help manage exceptions using market data. These are company-level developments, not individual inventions. They add an important dimension to his profile: a digital securities service still needs people and systems to resolve problems between counterparties when normal processing is interrupted.
Euroclear’s 2026 work provides the wider setting in which that executive remit operates. In March, it joined DTCC, Clearstream and Boston Consulting Group in publishing an interoperability framework addressing data standards, ownership recognition and consistent processes. In June, Euroclear and Societe Generale-FORGE announced an assessment of USD CoinVertible for settlement of tokenised dollar-denominated commercial paper. The former is a proposed industry framework; the latter was explicitly exploratory. Neither announcement establishes that Queiroz led those projects personally, but both show why integration and coordination remain central to the institution’s digital agenda.
Why Katharos.ai Follows Antonio Queiroz
Katharos.ai follows Queiroz because the transition to digital assets depends partly on executives able to connect new infrastructure to existing client services. His documented remit, D-FMI statements and operational-governance experience make him useful to understanding that transition. The relevant questions are practical: can issuers and investors use a new service through familiar channels, can teams support it consistently, and can digital records connect with established settlement processes? These questions are visible in the World Bank transaction and in the separate workflow activities around Euroclear.
The editorial interest also lies in the boundaries between technological possibility and implementation. A completed bond issue is stronger evidence of use than a concept announcement, while a first transaction does not establish broad adoption or prove cost savings across a market. Queiroz’s profile offers a way to examine that progression without turning every institutional partnership into a personal achievement. His influence is best assessed through responsibilities, documented participation and observable delivery.
Areas to Follow
- D-FMI adoption: additional issuers, repeat use and evidence that participants can integrate digital issuance into ordinary securities operations. - Interoperability: whether proposed standards become usable connections between systems, with clear responsibility for records and asset movements. - Settlement cash: the results of Euroclear’s stablecoin assessment, preserving the distinction between exploratory work and a launched service. - Operational change: the practical relationship between client experience, exception management and the delivery of digital-market services.
Reporting Scope
This profile covers Queiroz’s public professional career and documented connection to digital-market infrastructure. His current CDO role is verified from Euroclear; the Taskize chairmanship is described against the dated December 2025 record. Company programmes are attributed to their organizations unless sources establish his personal role. The profile does not assess investment suitability, forecast tokenisation revenues or treat an institution’s stated benefits as measured outcomes.
Areas of Influence
His primary category is Exchanges & Infrastructure, particularly post-trade modernization, digital securities and the operating systems around institutional finance. Digital-bank product experience and technology entrepreneurship provide background to that work. Stablecoin settlement and industry standards are relevant developments to follow within his organization, rather than separate claims that he is a stablecoin issuer or regulatory authority.
