Six Swiss Exchange faced a major disruption in trading due to technical issues, causing a halt in activities. Equities, ETFs, ETPs, and investment funds were affected, leading to a suspension in trading. The issue, which impacted both equities and bonds, arose from a data problem with the trading systems at the exchange.
Despite efforts to resolve the problem, trading was briefly resumed but had to be halted again as the technical issues persisted. The exchange confirmed that no matching was occurring during this period. Market sources indicated that the technical problems with SIX MDDX had been addressed, but the cause was still under investigation.

As the situation unfolded, trading in various asset classes was expected to resume at staggered times to ensure a smooth transition back to normal operations. However, the impact extended beyond Six Swiss Exchange, affecting MTFs across Europe, including Bolsas y Mercados Españoles (BME).
Market data suppliers like Turquoise and Aquis Exchange also faced challenges due to the disruption, with trading on their platforms being affected by the data feed issues. Turquoise confirmed that the inbound market data feed from Six Swiss Exchange was unavailable, leading to a suspension of trading for certain instruments.

This incident was not the first disruption experienced by Six Swiss Exchange, with a previous outage in June 2023 resulting in a three-hour halt in trading. The recent technical issues highlighted the importance of robust systems and contingency plans to mitigate the impact of such disruptions on the market.
Industry experts emphasized the need for transparency and swift resolution of technical issues to maintain market integrity and investor confidence. While such incidents are disruptive, they also serve as learning opportunities for exchanges and market participants to enhance their resilience and response mechanisms.

Market participants are awaiting further details on the root cause of the technical problems and the steps taken to prevent similar incidents in the future. The incident underscores the interconnected nature of global financial markets and the importance of collaborative efforts to address system vulnerabilities and ensure the smooth functioning of exchanges.
