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, up from 50% in the spring. Australia’s APRA said frontier AI models are accelerating cyber threats and that its 2027 system-wide stress test will examine AI-driven disruption. Both supervisors also point to risks from financial institutions relying on shared providers.
The Federal Reserve said 87% of surveyed market contacts cited artificial intelligence as a risk to U.S. financial stability in its November report, while Australia’s prudential regulator said it will examine AI-driven disruption in a 2027 system-wide stress test. The developments put attention on risks ranging from AI-related market valuations and cyber threats to financial institutions’ dependence on a small number of technology providers.

The Federal Reserve Bank of New York collected responses from 23 market contacts in September and October, including professionals at broker-dealers, banks, investment funds and advisory firms. The report, released November 13, says 87% cited AI as a risk over the next 12 to 18 months, compared with 50% of 20 contacts surveyed in March and April. The Fed cautioned that the survey summarizes respondents’ views and does not represent the views of the Federal Reserve Board or the New York Fed.
Respondents described several distinct concerns. They pointed to the possibility of a sharp correction in AI-related shares if returns fail to match large investment spending, with stretched valuations, debt and complex financing potentially amplifying losses. They also cited AI-enabled cyberattacks and the possibility of unintended harm from frontier models, as well as risks tied to complex AI-related financing. Cyberattacks and fiscal debt sustainability were rated by respondents as risks with particularly severe potential consequences.
The Fed’s report also documents the scale of financing and exposure around the computing buildout: debt issuance tied to advanced computing 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 have close to $1 trillion in exposure to firms and vehicles behind that buildout. Separately, Australia’s APRA said frontier models, including those from Anthropic and OpenAI, are improving at finding and exploiting software flaws.
Risks Across Markets and Providers
The survey signals that financial professionals are increasingly concerned about AI’s potential to affect several parts of the system at once. A sharp repricing of AI-related assets could affect companies and lenders tied to the buildout, while cyber incidents could disrupt financial services. The Fed’s figures on issuance and bank exposure show why the financing behind computing infrastructure is part of the stability discussion, though they do not establish that losses or a market correction are imminent.
Both supervisors also highlight the risk of concentration in shared providers. Banks, insurers and other institutions may depend on the same models, platforms or cloud and technology services. A disruption or compromise at a widely used provider could affect multiple institutions at the same time. APRA reported that few institutions in its review of large banks, insurers and pension funds had tested how to switch away from critical AI providers, leaving uncertainty about how well they could manage a failure.

Two Supervisors, Different Findings
The New York Fed conducts its market-contact survey twice a year to ask what shocks respondents believe could do the most damage to the U.S. financial system over the following 12 to 18 months. The latest responses were collected before November, and the report’s data cutoff was October 28, 2026. AI’s 87% result is therefore a measure of views among this small panel at that time, not a forecast or a finding that the risks have materialized.
APRA’s November 12 System Risk Outlook addresses risks to Australia’s financial system and sets out areas for supervisory attention. Its planned 2027 System Stress Test will examine AI-driven economic disruption. APRA had also warned in an April 30 letter to industry about frontier AI and cyber threats. The Fed and APRA are describing related concerns, but their reports cover different jurisdictions and use different methods.
“Many respondents noted that advances in AI are lowering the barrier to sophisticated attacks by state and non-state actors, while others pointed to the risk of unintended damage caused by frontier AI models themselves.”

Limits of the Risk Picture
The Fed survey reflects 23 respondents, not a representative measure of the entire financial industry, and the increase from 50% to 87% does not show how likely a specific event is. The survey also predates November developments. The report presents respondents’ concerns; it does not establish that AI-related valuations will correct, that a cyber incident will occur, or that financing will produce losses.
APRA’s warning identifies improving capabilities in frontier models, but the material provided does not quantify how often those capabilities have been used in successful attacks or the likely financial impact. Details of the 2027 stress test, including its scenarios, participating institutions and publication schedule, have not been specified. It is also unclear how many institutions could switch providers quickly if a critical service failed.
APRA’s 2027 Stress Test
APRA’s next system-wide stress test is planned for 2027 and will examine AI-driven economic disruption. Further details will be needed to show how the regulator will translate that aim into scenarios and assess institutions’ responses. The Fed’s market-contact survey is conducted twice a year, so a later survey may show whether AI remains a leading concern among respondents.
For financial institutions and their customers, the immediate issues raised by the reports are exposure to AI-related financing, resilience against cyber threats and the ability to maintain services if a shared provider is disrupted. The published findings do not specify a new rule or a deadline for institutions to change their practices.
Key Questions
What does the Fed’s 87% figure measure?
It is the share of 23 market contacts surveyed in September and October 2026 who cited AI as a risk to U.S. financial stability over the next 12 to 18 months. The Fed says these are respondents’ views, not the central bank’s own assessment.
What AI-related risks did the contacts identify?
They cited possible corrections in AI-related stock valuations, cyber threats enabled by AI or involving unintended effects from frontier models, and complex financing tied to AI. The survey does not establish that these events will happen.
What will Australia’s 2027 stress test examine?
APRA says its system-wide stress test will examine AI-driven economic disruption. The published material does not yet set out the test’s scenarios or participating institutions.
If many institutions rely on the same critical provider, a failure or compromise could affect them at once. APRA reported that few institutions in its review had tested a way to switch away from critical AI providers.
