TL;DR
Australia’s prudential regulator says its 2027 system-wide stress test will examine AI-driven economic disruption. Separately, 87% of 23 market contacts surveyed by the New York Fed in September and October named AI as a risk to U.S. financial stability, up from 50% in the spring; the Fed says the responses represent contacts’ views, not its own.
Australia’s prudential regulator plans to examine AI-driven economic disruption in its 2027 system-wide stress test, as a new Federal Reserve survey found that 87% of 23 market contacts named AI as a risk to U.S. financial stability. The two developments, reported on November 12 and 13, respectively, put financial supervisors’ attention on AI-related cyber threats, debt and the possibility that many institutions depend on the same technology providers.
The New York Fed surveyed market contacts in September and October for the central bank’s November Financial Stability Report. AI was the most frequently named risk, up from 50% of 20 respondents in the spring survey. The Fed cautioned that this section summarizes respondents’ views and does not represent the views of the Federal Reserve Board or the New York Fed. The report’s information cutoff was October 28, so the survey does not include events after that date.
Respondents described several distinct AI-related risks: high valuations for AI-linked companies if investment returns disappoint, cyberattacks enabled by advances in AI, and complex financing tied to AI infrastructure. Other risks cited included a correction in risk assets at 52%, higher long-term interest rates at 48%, and cyberattacks and fiscal debt sustainability at 43% each. These percentages describe the survey responses, not the probability of those events occurring.
The Fed report also sets out figures on financing for advanced computing. It says related debt issuance exceeded $680 billion by October 2026, about 31% of investment-grade nonfinancial corporate issuance, compared with less than 6% in 2023. The report says the largest U.S. bank holding companies had close to $1 trillion in exposure to firms and vehicles involved in the buildout. Separately, Australia’s APRA said frontier models, including those from Anthropic and OpenAI, are improving at finding and exploiting software flaws.

The concern for financial stability is not limited to whether AI companies’ valuations fall. Supervisors are also watching for operational disruption if a widely used AI or technology provider fails, suffers a cyber incident or becomes unavailable. If many banks, insurers or market infrastructure firms rely on the same provider, a problem at one company could affect several institutions at once.
The Fed says attacks on critical third-party service providers could have wider effects when institutions cannot readily substitute another service. It warns that disruption at a financial institution could contribute to weaker market liquidity, reduced investor or depositor confidence and forced asset sales. APRA’s findings point to a practical weakness: it found few institutions had tested how they would switch away from critical AI providers. That makes provider concentration and contingency planning relevant to companies as well as regulators and customers.
The financial exposure figures also connect the AI boom to traditional market risks. Heavy borrowing to build computing infrastructure could leave firms vulnerable if expected returns do not arrive, while banks may be exposed through loans and other connections. The Fed’s report identifies these as areas of concern; it does not say that losses or a market correction are certain.

Two Supervisors, Different Evidence
The Federal Reserve’s report combines a small survey of market contacts with the Board’s own discussion of financial-system vulnerabilities. The survey involved 23 contacts from broker-dealers, banks, investment funds and advisory firms, compared with 20 in spring. Its results show what those respondents considered risks over the next 12 to 18 months, not a measured forecast of likely outcomes. The Fed says respondents rated cyberattacks and fiscal debt sustainability as having the most severe potential consequences.
In its assessment, the Fed described the banking system as “sound and resilient”, while noting high equity valuations partly linked to enthusiasm for superintelligence. It also reported that mentions of agentic systems being involved in cyber events had increased since its May report, without providing a count. The report says newer capabilities in large language models and agentic systems to detect and exploit vulnerabilities create challenges for financial institutions, infrastructure and third-party providers.
APRA’s System Risk Outlook, released on November 12, takes a supervisory and forward-looking approach. It identifies frontier AI models as part of a changing cyber threat and says the regulator’s 2027 System Stress Test will examine AI-driven economic disruption. The announcement does not mean that the test has already been conducted or that APRA has quantified the likely impact.
The Test’s Scope Is Not Yet Detailed
APRA has said its 2027 test will examine AI-driven economic disruption, but the material provided does not specify the test scenarios, participating institutions, measures of resilience or publication date for results. It is also unclear how the regulator will assess dependence on particular AI providers or how it will distinguish AI-specific disruption from wider cyber and economic shocks.
The Fed survey has limits of its own: it involved 23 unnamed contacts, and the report does not identify individual respondents or assign probabilities to the risks they cited. The figures on borrowing and bank exposure describe reported financial connections; they do not establish that those exposures will result in losses. The report also gives no count for the increase in reports involving agentic systems and cyber events.
Both supervisors identify risks and areas for attention, not evidence that a major AI-related financial disruption has occurred. The degree to which institutions can move to alternative providers, and whether planned controls would work under stress, remains uncertain.
APRA’s 2027 Test Will Probe Resilience
The next stated milestone is APRA’s 2027 System Stress Test, which is set to examine AI-driven economic disruption. Further detail from APRA will be needed to show how the test translates that objective into scenarios and what it expects supervised institutions to demonstrate.
For financial firms, the issues raised by both supervisors include tracking exposure to AI infrastructure financing, strengthening defenses against AI-enabled cyber threats and testing contingency plans for essential third-party services. Those are implications of the risks described in the reports, not announced requirements in the material provided.
The Fed’s survey and assessment were published in its November 2026 Financial Stability Report, with data through October 28. Readers should distinguish those dated findings from later developments: the survey is a snapshot of market contacts’ views, while APRA’s test remains a future exercise whose detailed design and results are not yet available.
Key Questions
What did Australia announce?
APRA said its 2027 System Stress Test will examine AI-driven economic disruption. The available announcement does not specify the scenarios or test results.
What does the Fed’s 87% figure measure?
It is the share of 23 market contacts surveyed in September and October who named AI as a risk to U.S. financial stability. It is not a probability that AI will cause a crisis, and the Fed says the responses are not its own views.
What AI risks did respondents identify?
They cited potential corrections in AI-related valuations, AI-enabled cyberattacks and complex financing connected to AI. The Fed’s report separately discusses risks from reliance on third-party providers.
Why are shared AI providers a concern?
If several institutions depend on the same provider, an outage or cyber incident could affect them at once. APRA said few institutions had tested ways to switch away from critical AI providers.
Does the Fed say the financial system is in immediate danger?
No. The report describes the banking system as “sound and resilient” while identifying vulnerabilities supervisors and market participants are monitoring. The survey reports perceived risks, not confirmed future events.
