Global Financial Regulators Warn AI Threatens Systemic Stability of Markets

FSB, FINRA, and Canada’s OSFI have each flagged artificial intelligence as a threat to financial stability, citing risks including high valuations, growing retail leverage, and heightened cyber vulnerabilities

Some of the world’s most influential financial regulators are sounding the alarm on artificial intelligence—not merely as a compliance issue for individual firms, but as a structural risk capable of destabilizing global financial markets.

In a letter to G20 finance ministers and central bank governors dated August 28, Andrew Bailey, chair of the Financial Stability Board and governor of the Bank of England, identified frontier artificial intelligence as one of the most urgent emerging threats to the international financial system.

The warning comes at a moment when AI-related asset valuations are described by the FSB as “elevated,” and as retail investors are increasingly buying into leveraged products tied to the sector.

“Frontier AI may have the capacity materially to alter the speed, scale, and economics of cyber risk, which could undermine confidence across the entire financial system,” Bailey wrote in the letter.

A convergence of risks

The FSB’s concerns are threefold. First, it flags the financial stability implications of highly concentrated AI-sector investment, noting that cross-investment between AI companies and large cloud and computing providers—so-called hyperscalers—creates an amplification risk if valuations correct sharply.

Second, it identifies a rise in leveraged trading strategies, including among retail investors, as a characteristic of what it calls “a maturing financial cycle.”

Third, and most alarmingly, it warns that many jurisdictions lack the regulatory frameworks needed to manage the development and deployment of advanced frontier AI models.

“Rising leverage is a hallmark of a maturing financial cycle,” Bailey noted. “While it can amplify gains during rising markets, it can also intensify declines when conditions turn.”

Investment advisors are already receiving heightened questions about pre-IPO AI exposure and the risks of entering high-profile listings at inflated prices. The FSB’s communiqué adds a macro-prudential dimension to those conversations: the danger is not only a matter of portfolio risk, but potentially of system-wide contagion.

FINRA issues warning to US broker-dealers

The FSB’s warning is not an isolated signal. In its 2026 Annual Regulatory Oversight Report, the Financial Industry Regulatory Authority made clear that the growing prevalence of generative AI tools across broker-dealer operations heightens firms’ regulatory obligations.

FINRA flagged concerns around data quality, model bias, and the governance of AI-generated client communications, requiring that firms subject AI-driven client interactions to the same supervisory rigor as any other client-facing activity.

The report, published January 2026, explicitly cautions against dependence on limited or outdated datasets, which can produce skewed outputs in client-facing tools—a particularly pressing concern in an environment where AI is rapidly reshaping how advisors interact with clients and communicate investment recommendations.

North of the border, similar alarm bells

In Canada, the Office of the Superintendent of Financial Institutions and the Financial Consumer Agency of Canada have jointly documented the scale of the risk.

Their joint report, based on data showing AI adoption among financial institutions rising from roughly 30% in 2019 to 50% in 2023—and projected to reach 70% by 2026—warns that the sector cannot treat AI risk management as optional, even for institutions not yet deploying the technology.

The OSFI-FCAC report notes that the International Monetary Fund estimates 60% of jobs in advanced economies will be affected by AI automation, and that severe cyber-attack costs on financial institutions have quadrupled in recent years.

Ninety-one percent of financial institutions are reevaluating voice-verification systems in response to AI-enabled voice cloning, according to a Biocatch survey cited in the report.

A July 2024 global IT outage, included in the report as a case study in third-party concentration risk, resulted in approximately $5.4 billion in financial losses—illustrating the systemic exposure that can follow from dependence on a small number of shared technology providers.

The FSB has called on global authorities to establish coordinated, cross-border protocols for the safe release and deployment of frontier AI models, and to strengthen recovery capabilities in the event of simultaneous disruption across multiple financial institutions.

Whether those frameworks can be enacted quickly enough to keep pace with AI development is an open question that regulators across continents are now posing with increasing urgency.
