BYMA Implements New Low-Latency Trading System Version

As part of its commitment to technological innovation and operational excellence, BYMA is proud to announce the implementation of a new version of its trading system. This marks the first time a low-latency network for Capital Markets services has been implemented in Argentina.

This pioneering technological evolution significantly minimizes latency measurements in critical path networks for financial markets. The solution was developed with technology from LSEG (London Stock Exchange Group), a global leader in financial markets solutions and BYMA's technology partner.

The new version of the system enhances the elasticity and speed of data access—key attributes for responding to an increasingly competitive, automated, and dynamic environment.

María José del Boca, Chief Product & Client Officer, said: "This new version of the trading system marks a strategic advance for the Argentine capital markets. It's the result of a clear and sustained vision of growth, driven by the incorporation of world-class technology. At BYMA, we work with a deep commitment to operational excellence and constant innovation because we believe that a solid and modern infrastructure is key to boosting the country's economic development and generating value for investors, participants, and society as a whole."

For his part, BYMA's CIO, Maximiliano Ignaciuk, added: "The solution we implemented is groundbreaking in terms of speed, built on a new network and platform with features previously unseen in the Argentine market. This allows us to enhance trading conditions, aligning with international standards and meeting a very demanding service level for our critical path infrastructure. We have reduced latency in our trading service to a minimum and significantly increased availability and scalability—a fundamental factor for Capital Markets participants."

The Argentine capital market is experiencing exponential growth. By the end of 2024, the total number of investor accounts surged by 81% compared to the end of 2023. Currently, over 17 million investor accounts are open at Caja de Valores, the depository that safeguards the market's marketable securities; these accounts correspond to 9 million individuals. In line with this trend, the total traded volume increased by 133% when comparing the first quarter of 2025 to the first quarter of 2024.

‍Innovation at the Service of Market Development

With this implementation, BYMA reaffirms its leadership in adopting innovative technological solutions. This benefits both market participants and investors by providing a more efficient and agile experience.

The trading cycle is evolving towards end-to-end integration with world-class technology, including: Trading (Millennium), Market Data (EPAM), Post-trade (Nasdaq), and Central Securities Depository (Nasdaq).
