TL;DR
In its November 2026 Financial Stability Report, the Federal Reserve said 87% of 23 market contacts surveyed in September and October named AI as a risk to U.S. financial stability. Australia’s APRA said its 2027 system stress test will examine AI-driven disruption, as supervisors flag cyber threats, financing risks and dependence on shared providers.
Artificial intelligence was the most frequently cited risk in the Federal Reserve’s latest survey of market contacts, with 87% of 23 respondents naming it as a potential threat to U.S. financial stability over the next 12 to 18 months. Separately, Australia’s prudential regulator APRA said its 2027 system-wide stress test will examine disruption driven by AI, as both supervisors raise concerns about cyber threats and reliance on common technology providers.
The Federal Reserve’s November 13 Financial Stability Report says New York Fed staff gathered responses from 23 contacts in September and October, including professionals at broker-dealers, banks, investment funds and advisory firms. The AI share rose from 50% among 20 contacts in the spring survey. The Fed cautioned that the survey summarizes respondents’ views and does not represent the views of the Board or the New York Fed.
Respondents’ AI concerns covered several distinct risks: a possible correction in AI-related stocks if returns fail to justify large investments; cyberattacks made easier by advances in AI, including possible unintended damage from frontier models; and complex AI-related financing. The report lists a correction in risk assets as the next most-cited risk, at 52%, followed by higher long-term interest rates at 48%. Cyberattacks and fiscal debt sustainability, each cited by 43%, were rated by respondents as risks with particularly severe potential consequences.
The report also gives figures on financing for advanced computing. It says related debt issuance exceeded $680 billion by October 2026, around 31% of investment-grade nonfinancial corporate issuance, compared with less than 6% in 2023. The report says the largest U.S. bank holding companies have close to $1 trillion in exposure to companies and vehicles supporting the buildout. APRA’s November 12 System Risk Outlook, meanwhile, says frontier models, including those from Anthropic and OpenAI, are improving at finding and exploiting software vulnerabilities.

AI Risks Reach Financial System Planning
The reports point to a risk that extends beyond whether AI companies’ valuations are sustainable. If AI tools make sophisticated cyber activity easier, financial firms and the infrastructure they depend on could face new security pressures. The Fed says an attack on a critical third-party service provider could affect multiple institutions, particularly where firms have limited ability to substitute another provider.
That shared-provider exposure links operational risk to financial stability. A disruption affecting several institutions could, the Fed says, degrade market liquidity, weaken investor or depositor confidence and contribute to forced asset sales. The survey itself does not establish that these outcomes will occur; it records the concerns of a small group of market professionals. APRA’s planned test signals that Australian supervisors intend to examine how AI-related disruption could affect the wider system.
Rising borrowing for advanced computing adds a financial channel to the concern. If the expected returns from infrastructure spending disappoint, debt-funded projects and elevated valuations could come under pressure. The figures establish the scale of financing described in the report, but do not show that defaults or a market correction are imminent.

Two Supervisors, Different Evidence
The Fed’s Financial Stability Report combines its own assessment with a survey of market contacts. The survey covers perceived risks over the following 12 to 18 months; it is not a forecast that the most-cited event will happen. The report says the data it reflects were current as of October 28, so the contacts’ answers predate developments in November.
The Fed describes the U.S. banking system as “sound and resilient” while also noting high equity valuations, partly associated with enthusiasm for superintelligence. Its discussion of cybersecurity says recent advances in large language models and agentic systems have created new challenges for protecting financial institutions, infrastructure and third-party service providers. The report also says reports of agentic systems being involved in cyber events have increased since its May report, without quantifying that change.
APRA’s System Risk Outlook is a separate Australian supervisory assessment. Its reference to Anthropic and OpenAI concerns frontier models’ capabilities in finding and exploiting software flaws; it is not evidence that either company’s models caused a financial-sector incident. APRA says its next system-wide stress test, planned for 2027, will examine AI-driven economic disruption. The two publications therefore identify related concerns, but arise from different jurisdictions and forms of evidence.

Survey Limits and Test Details
The Fed survey involved 23 contacts, and the report does not identify them. Its results show how often those contacts named each risk, not the probability that a given event will happen or a consensus view across the entire financial sector. The survey also offers no quantified estimate of the financial losses a major AI-related disruption could cause.
APRA has said the 2027 stress test will examine AI-driven disruption, but the available account does not specify the test’s scenarios, participating institutions, measures or timetable. It is also unclear how supervisors will assess whether firms can switch away from a critical AI or technology provider. The source says few institutions had tested an ability to switch, but gives no count or further breakdown.
The Fed’s references to increased reports of agentic systems being involved in cyber events do not include a number, specific incidents or evidence tying those events to attacks on financial institutions. The reports describe risks and supervisory concerns; they do not establish that AI has already caused system-wide financial instability.
APRA’s 2027 Test Takes Shape
The next stated milestone is APRA’s 2027 system-wide stress test, which will examine AI-driven economic disruption. APRA has not yet provided details of the scenarios or how results will be reported. The test may offer a clearer view of how supervisors plan to assess exposures across institutions, including risks tied to reliance on shared providers.
In the United States, the Fed report gives no separate date for a follow-up action on these findings. Its twice-yearly contact survey provides a basis for comparing how perceived risks change in later reports, while its current assessment highlights cybersecurity, market valuations and data-center financing. Further information from regulators will be needed to show whether institutions are changing their safeguards or contingency plans in response.
Key Questions
What did the Fed’s AI risk figure measure?
87% of 23 market contacts surveyed in September and October named AI as a risk to U.S. financial stability over the next 12 to 18 months. It measures respondents’ views, not the probability of an AI-related crisis.
What risks did respondents associate with AI?
They cited possible corrections in AI-related stock valuations, AI-enabled cyber threats and complex financing connected to AI development and infrastructure. The report treats these as separate concerns.
What will Australia’s APRA test examine?
APRA says its 2027 system-wide stress test will examine AI-driven economic disruption. Details on scenarios, participating institutions and the testing method have not yet been provided.
Did the reports say Anthropic or OpenAI caused a financial cyberattack?
No. APRA said frontier models, including those from Anthropic and OpenAI, are improving at finding and exploiting software flaws. The available source does not attribute a financial-sector attack to either company.
Why are shared AI and technology providers a concern?
The Fed warns that an outage or attack involving a critical third-party provider could affect multiple institutions, especially if they cannot readily switch to another service. APRA’s outlook also raises questions about firms’ ability to move away from critical AI providers.
