TL;DR
Australia’s prudential regulator, APRA, says its 2027 system-wide stress test will examine AI-driven economic disruption. The announcement follows a Federal Reserve report in which 87% of 23 surveyed market contacts named AI as a financial-stability risk, while both supervisors highlight cyber threats and reliance on shared technology providers.
Australia’s prudential regulator, the Australian Prudential Regulation Authority (APRA), says its 2027 System Stress Test will examine economic disruption driven by artificial intelligence, as a new Federal Reserve report records rising concern about AI-related financial risks in the United States. The Fed said 87% of 23 market contacts surveyed in September and October named AI as a risk to financial stability, up from 50% in the spring; that figure reflects respondents’ views, not a finding or forecast by the Fed.
APRA’s System Risk Outlook, issued November 12, said frontier AI models, including those from Anthropic and OpenAI, are improving at finding and exploiting software vulnerabilities. APRA said it would examine AI-driven disruption in its next system-wide stress test, planned for 2027. The available account does not specify the test’s scenarios, participating institutions or how results will be published.
The Federal Reserve’s Financial Stability Report, released November 13, describes several distinct concerns raised by its market contacts: a possible correction in AI-related share valuations if returns fail to match heavy investment, AI-enabled cyberattacks, and complex financing tied to AI infrastructure. The Fed also warns that an attack or outage at a critical third-party provider could affect multiple financial institutions, especially where replacing the provider is difficult.
The report includes measures of the financing behind 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. It also says the largest U.S. bank holding companies have close to $1 trillion in exposure to companies and vehicles involved in the buildout. Those figures describe exposure and financing; they do not establish that losses or a financial crisis are imminent.

The two regulators point to risks that can cross institutional boundaries. If many banks and other financial firms rely on the same AI or cloud services, an outage, cyber incident or failure at one provider may affect several organizations at once. The Fed says limited ability to substitute for a critical service could amplify disruption. It warns that a financial institution’s disruption could weaken market liquidity, erode investor or depositor confidence and force asset sales.
That makes provider concentration and continuity planning relevant beyond the technology sector. APRA reportedly found that few institutions had tested a way to switch away from critical AI providers. If that finding holds across the institutions it reviewed, it points to a practical gap between recognizing reliance on vendors and demonstrating that essential services can continue when a vendor is unavailable. The source material does not give the number of institutions assessed or the method behind that finding.
The financial exposures also matter because AI-related investment is being financed at scale. If expectations for AI earnings fall short, losses could reach investors and lenders through valuations, debt and related financing arrangements. The Fed report identifies these channels as concerns; it does not say that a correction will happen or quantify likely losses. The stress test could help Australian supervisors examine how such pressures might interact, though its design has not yet been described.

Two Supervisors, Different Evidence
The Federal Reserve’s survey is a twice-yearly snapshot of what market contacts see as the largest threats to U.S. financial stability over the next 12 to 18 months. For the latest round, New York Fed staff received responses from 23 contacts in September and October, including professionals at banks, broker-dealers, investment funds and advisory firms. In the spring survey, 50% of 20 contacts named AI; the latest report puts the share at 87%. These percentages compare two small panels and should not be read as a measure of the likelihood of an AI-related crisis.
The Fed listed a correction in risk assets at 52% of respondents, higher long-term interest rates at 48%, and cyberattacks and fiscal debt sustainability at 43% each. It said cyberattacks and fiscal debt sustainability were rated as having the most severe potential consequences. The report explicitly cautions that the survey summary represents respondents’ views, not the views of the Federal Reserve Board or the New York Fed. The report’s data are as of October 28, so the survey and underlying assessment predate events in November.
Alongside the survey, the Fed’s own assessment says the U.S. banking system is “sound and resilient.” It also notes high equity valuations, partly associated with enthusiasm for superintelligence, and describes new security challenges from large language models and agentic systems detecting and exploiting vulnerabilities. APRA’s outlook is a separate supervisory assessment focused on Australian institutions. The parallel concerns are meaningful, but the two documents use different methods and do not amount to a joint finding.
Stress Test Design Is Not Yet Public
APRA’s stated plan does not yet explain which AI-related shocks the 2027 test will model, which firms or services will be included, or what measures of resilience it will use. It is also unclear whether APRA will publish institution-level findings, aggregate results or recommendations, and on what timetable. The cited source material reports APRA’s view that few institutions have tested provider switching, but does not detail the sample or testing criteria.
The Fed’s 87% figure is a survey result from 23 unnamed contacts, not a representative estimate of all financial-market participants and not a probability of failure. The Fed also does not provide a count for its statement that reports of agentic systems being involved in cyber events have increased since May. Neither regulator’s statements establish that a particular AI model caused a specified financial loss or that a system-wide incident is underway.
APRA’s 2027 Test Takes Shape
The next concrete milestone is APRA’s development and conduct of its 2027 System Stress Test. Further details about its scenarios, participating institutions and publication plans will be needed to judge how directly it tests the risks identified in the outlook. Financial firms and their supervisors will also face the practical question of whether critical services can continue if a widely used AI or technology provider is disrupted.
In the United States, the Fed’s report adds AI-related cyber risk and data-center financing to its ongoing financial-stability monitoring. The report does not announce a specific new test or policy response. Readers should watch for future supervisory documents that quantify exposures, clarify provider dependencies or set out how authorities expect institutions to manage AI-related operational risk.
Key Questions
What will Australia’s 2027 AI stress test examine?
APRA says its 2027 System Stress Test will examine economic disruption driven by AI. It has not yet set out the test’s scenarios, participants or reporting arrangements in the source material.
What does the Fed’s 87% figure mean?
It means 87% of 23 market contacts surveyed in September and October named AI as a financial-stability risk. The Fed cautions that the result summarizes respondents’ views and does not represent the Fed’s own view or a forecast.
What AI-related risks did the Fed report?
Contacts cited possible AI-related equity valuation corrections, AI-enabled cyberattacks and complex AI financing. The Fed’s own report also discusses security risks from AI systems and the potential for disruption at critical third-party providers to affect multiple institutions.
Why are shared AI providers a concern?
If several financial firms depend on one provider, an outage or attack could disrupt more than one institution. The Fed says limited ability to replace a critical provider could make the effects worse; APRA’s outlook says few institutions had tested switching away from critical AI providers.
Does the Fed report say a financial crisis is likely?
No. The survey records concerns, while the report’s assessment says the U.S. banking system is “sound and resilient.” Its figures on borrowing and bank exposure describe scale, not a prediction that losses or a crisis will occur.
