Deutsche Börse, Wiener Börse Extend T7 Partnership Through 2033

Deutsche Börse Group and Wiener Börse have extended their long-standing trading technology partnership, with the T7 system set to continue operating markets across Central and Eastern Europe through 2033, according to the companies’ announcement. The agreement covers trading activity in Vienna and Prague, as well as partner exchanges in Budapest, Ljubljana, and Zagreb, maintaining a shared infrastructure model that has been in place for decades.

Partnership Scope and Affected Markets

The extension ensures that multiple exchanges will continue to operate on a common trading platform, supporting cross-market consistency in execution and system access. The agreement covers trading activity in Vienna and Prague, as well as partner exchanges in Budapest, Ljubljana, and Zagreb.

Christoph Boschan, Chief Executive Officer of Wiener Börse, stated: “We continue to rely on an internationally established system with which global market participants are thoroughly familiar. The continuation of this reliable partnership offers all trading members continuity in planning and proven access to highly efficient exchange technology.”

T7 System and Ongoing Development

The T7 system, developed by Deutsche Börse, has been used by the Vienna Stock Exchange since its earlier Xetra system was introduced in 1999. The T7 trading system forms the backbone of Deutsche Börse’s cash market operations and is used by several exchanges globally. It supports electronic trading across asset classes, with ongoing updates to software and hardware intended to maintain performance and security.

The agreement includes continued development of the platform, with regular releases and upgrades to adapt to evolving market requirements and regulatory standards.

Eric Leupold, Head of Cash Market at Deutsche Börse Group, commented: “We are pleased to continue providing the Vienna Stock Exchange and its partner network with one of the most powerful and secure exchange systems. In further developing the software, we adhere to the highest security and industry standards and drive forward the technical innovation that is immensely important for modern exchange trading in close cooperation with our hardware partners.”

Regional Integration Through Shared Technology

The partnership supports a broader model in which Wiener Börse acts as a technology provider for exchanges in Central and Eastern Europe. The rollout of the trading system across Ljubljana, Prague, Budapest, and Zagreb over the past decade created a network of markets operating on shared infrastructure.

This structure allows for coordination across markets while maintaining separate exchange operations. It also supports cross-border trading by providing a unified technical framework. The use of a single system across multiple markets allows participants to interact with different exchanges through a consistent interface, reducing operational complexity for firms active in the region.

Trading Infrastructure and Market Competition

Trading infrastructure remains a central factor in exchange competition, with performance, latency, and reliability affecting how market participants choose where to trade. Extending the partnership signals a preference for continuity over system migration.

For market participants, stability in trading systems can reduce the need for operational changes, particularly for firms connected to multiple exchanges within the network. The agreement also reflects how exchanges increasingly rely on external or shared technology providers, rather than building proprietary systems independently.

By maintaining the T7 system across its network, Wiener Börse continues to align its markets with a broader infrastructure used by international participants, supporting access and interoperability.
