A5X, an emerging Brazilian derivatives exchange, has significantly strengthened its leadership by appointing Cícero Vieira as a Partner and Strategic Advisor. The former B3 Chief Operating Officer brings extensive experience to the venture as it prepares for its market debut. His primary focus will be on guiding the company's operational, risk, and regulatory strategies to ensure a robust launch.


A Veteran's Strategic Role

In his new capacity, Vieira will oversee the strategic development of A5X's operational and risk management frameworks. He will work closely with the internal teams to navigate the complex regulatory roadmap essential for launching a new exchange. This appointment is designed to ensure the platform is resilient and compliant with top international standards from day one.

Carlos Ferreira, co-founder and CEO of A5X, highlighted the importance of this appointment for the company's future. He described Vieira as one of the professionals who most deeply understands the mechanics and challenges of building an exchange in Brazil. Ferreira added that this addition significantly strengthens the company's execution capabilities on its path to becoming operational.

A Legacy of Market Innovation

Vieira's career spans over two decades and is marked by significant contributions to Brazil's market infrastructure. He played a central role in the historic consolidation resulting from the merger of BM&FBovespa and Cetip, which created B3. His leadership was instrumental in integrating complex clearing systems for both the derivatives and equities markets.

The move was praised by Edemir Pinto, former CEO of BM&FBovespa, who worked closely with Vieira. Pinto described him as a key architect in establishing Brazil as a global benchmark for market infrastructure. He commended Vieira for leading the construction of clearing, depository, and trading systems that are now recognized internationally.

Path to Launch and Market Impact

A5X is advancing on an ambitious timeline as it prepares to enter the market and introduce new competition. The company plans to have all its systems fully developed, tested, and integrated with major market participants by mid-2026. This schedule positions the new derivatives exchange for a planned operational launch in the fourth quarter of 2026.

The exchange is supported by a formidable group of shareholders from the global trading and clearing community. Its backers include prominent firms such as ABN AMRO Clearing, Ideal CTVM, IMC, Jump Trading Group, Optiver, and XTX Markets. This strong financial and strategic support highlights significant industry confidence in A5X's vision for the Brazilian market.


The appointment of Cícero Vieira is a clear statement of intent from A5X, adding immense credibility and operational expertise to its ranks. This strategic hire underscores the company's commitment to building a sophisticated and resilient market infrastructure for Brazil. As A5X moves toward its launch, Vieira's guidance will be pivotal in shaping the next generation of the country's derivatives landscape.
