Europe’s securities watchdog is warning that cyber threats to financial markets are escalating rapidly, with artificial intelligence accelerating both the scale and speed of potential attacks.
The alert came from the European Securities and Markets Authority, whose leadership said the combination of geopolitical tensions and increasingly sophisticated AI tools is creating a more dangerous and unpredictable risk environment for global finance.
According to ESMA chair Verena Ross, the evolution of AI models is fundamentally changing the nature of cyber threats. New systems are capable of identifying vulnerabilities in software faster than ever before, raising concerns that attacks could become harder to detect and even harder to stop once underway.
Regulators are particularly focused on advanced AI models that can autonomously scan systems, uncover hidden weaknesses, and potentially exploit them at speed. The implication is clear. Cyberattacks that once took weeks to plan and execute could now unfold in a fraction of that time.
For financial markets, the risks are amplified by the sector’s deep interconnectedness. A single breach in a critical system could cascade across institutions, disrupting trading, settlement, and liquidity flows. ESMA has warned that these vulnerabilities are especially concerning at a time when markets are already facing pressure from high asset valuations and geopolitical instability.
In response, the regulator is stepping up its engagement with financial institutions, urging them to reassess their cyber defences and prepare for a new generation of threats. This includes closer scrutiny of third-party technology providers, which play an increasingly central role in financial infrastructure. ESMA has already identified a group of key providers whose resilience could be critical to the stability of the broader system.
The warning also highlights a regulatory challenge. As AI becomes more embedded in financial systems, oversight frameworks must evolve to keep pace. Authorities are now grappling with how to monitor not just traditional institutions, but also the technology firms and AI developers whose tools underpin modern finance.
ESMA pointed to broader market risks that could interact with cyber threats. Ongoing geopolitical tensions, including conflicts affecting global energy markets, are adding volatility and increasing the likelihood of market shocks. In such an environment, a major cyber incident could have amplified consequences, potentially undermining investor confidence and market stability.
There are also emerging concerns about market conduct. The regulator noted that heightened volatility and technological complexity could create new opportunities for insider trading and other forms of market abuse, further complicating the supervisory landscape.
