IMF warns AI cyber threats could disrupt banks, payment systems and global financial stability if safeguards remain weak

The International Monetary Fund has warned that rapidly evolving AI cyber threats could destabilise banks, payment systems and financial markets if regulators and institutions fail to strengthen digital resilience.

In a fresh assessment released on Thursday, the IMF said artificial intelligence is transforming the global financial system by improving fraud detection and cyber defence capabilities, but is simultaneously empowering a dangerous new generation of machine-speed cyberattacks.

According to the Fund, increasingly sophisticated AI-driven attacks could trigger systemic disruptions capable of undermining confidence in financial institutions and causing severe market instability.

The IMF warned that extreme cyber incidents could create funding pressures, threaten the solvency of financial institutions and spark broader contagion across interconnected markets.

The organisation noted that banks, insurers and other financial firms now depend heavily on shared software systems, cloud infrastructure, payment networks and digital platforms, creating concentrated vulnerabilities that attackers may exploit simultaneously.

Concerns intensified following the unveiling of Claude Mythos Preview by Anthropic, an advanced experimental AI system reportedly capable of identifying and exploiting weaknesses across major operating systems and web browsers.

Cybersecurity analysts said the development highlights how quickly AI cyber threats are evolving and why regulators can no longer view cybersecurity as merely a technical issue.

“Attackers have the advantage over defenders because discovering and exploiting vulnerabilities can occur faster than patching and remediation,” the IMF stated.

The Fund stressed that the imbalance between offensive and defensive cyber capabilities could become catastrophic within a financial ecosystem increasingly dependent on interconnected digital infrastructure.

Although advanced offensive AI tools remain relatively restricted for now, the IMF warned that existing protections may weaken rapidly as such technologies become more accessible.

The organisation said the risks extend beyond banking because financial institutions share critical digital foundations with energy providers, telecommunications firms and public services.

As a result, an attack targeting a single vulnerable infrastructure layer could spread across multiple sectors, causing operational paralysis and market panic.

The IMF also cautioned that dependence on a limited number of software platforms, cloud providers and AI systems could amplify systemic risks.

A single exploited weakness, the Fund said, could simultaneously affect numerous institutions and trigger payment disruptions, liquidity shortages and fire-sale pressures across financial markets.

Despite the dangers, the IMF acknowledged that artificial intelligence remains one of the most powerful tools available for cyber defence.

Financial institutions are increasingly deploying AI systems to detect suspicious activity, prevent fraud, identify software flaws and accelerate responses to security breaches.

The Fund noted that AI can also strengthen software development by helping engineers identify vulnerabilities before systems are deployed.

However, it warned that these advantages would only materialise if institutions invest heavily in governance frameworks, human oversight and operational integration.

The IMF urged regulators to place greater emphasis on cyber hygiene, disaster recovery systems, business continuity planning and quality assurance measures to ensure resilience during major attacks.

The organisation also called for a fundamental shift in regulatory thinking, arguing that cybersecurity should now be treated as a core financial stability issue rather than an isolated technology challenge.

According to the IMF, traditional cyber defences are no longer sufficient against increasingly automated and sophisticated attacks.

The Fund advocated stronger resilience standards, deeper cooperation between governments and private institutions, improved intelligence sharing and tougher supervisory oversight.

It further emphasised the importance of cyber stress testing, scenario analysis and board-level supervision of digital risks as essential safeguards for modern financial systems.

The IMF warned that emerging and developing economies with weaker cybersecurity capabilities could face greater exposure to AI cyber threats, potentially creating vulnerabilities across the wider international financial system.

The organisation therefore called for stronger global collaboration and expanded capacity-building efforts to help preserve financial stability in the rapidly evolving AI era.
