TL;DR
In its November 13 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 plans to examine AI-driven disruption in its 2027 system stress test.
Artificial intelligence was the most-cited risk to U.S. financial stability in the Federal Reserve’s latest survey of market contacts: 87% of 23 respondents named it, compared with 50% in the spring. Separately, Australia’s prudential regulator, APRA, said frontier AI models are accelerating cyber threats and that its 2027 system stress test will examine AI-driven disruption.
The Federal Reserve Bank of New York collected responses from 23 market contacts in September and October for the Financial Stability Report released November 13. Respondents included professionals at broker-dealers, banks, investment funds and advisory firms. In the spring survey, conducted in March and April, 50% of 20 contacts cited AI. The report says these responses reflect the participants’ views, not the Federal Reserve’s own views.
Respondents’ AI concerns covered several different risks. They cited the possibility that AI-related stock valuations could correct if returns fail to justify large investments, with debt and complex financing potentially amplifying losses. They also pointed to AI-assisted cyberattacks and possible unintended damage from frontier models, as well as risks tied to complex AI-related financing.
The Fed’s report separately said debt issuance tied to advanced computing had exceeded $680 billion by October 2026, about 31% of investment-grade nonfinancial corporate issuance. It described this as roughly five times the $130 billion issued during all of 2023. The report also put the largest U.S. bank holding companies’ exposure to firms and vehicles behind the buildout at close to $1 trillion.

How AI Could Reach Bank Customers
The findings point to risks that could travel beyond technology companies. A correction in AI-linked assets or problems in financing the data-center buildout could affect lenders and investors exposed to those firms. The Fed’s exposure figure underscores that banks have connections to companies and financing vehicles supporting the expansion, though it does not mean those exposures will result in losses.
Cyber risk presents a separate route into the financial system. The Fed warned that an attack on a critical third-party service provider could affect multiple institutions, particularly if they cannot readily replace that provider. A disruption at a financial institution could, the report said, impair market liquidity, weaken investor or depositor confidence, and prompt forced asset sales. Those are potential consequences described by the Fed, not outcomes it says have occurred.
APRA’s focus on shared providers adds a practical concern: institutions may depend on a small number of technology vendors, including AI providers. If several institutions rely on the same service, a provider failure or cyber incident could create simultaneous operational problems. The regulators’ concerns therefore extend to banks, insurers, other businesses reliant on AI services, and customers who depend on those institutions.

Two Supervisors, Different Measures
The Fed report combines a survey of market participants with the Board’s assessment of financial stability. The survey asks contacts which shocks could most damage the U.S. system over the next 12 to 18 months. Alongside AI, respondents cited a correction in risk assets (52%), higher long-term interest rates (48%), cyberattacks (43%) and fiscal debt sustainability (43%). These percentages refer to the latest group of 23 contacts; the spring comparisons used 20 respondents.
The Board’s own report described the U.S. banking system as “sound and resilient”, while noting high equity valuations partly linked to enthusiasm for superintelligence. It also said recent advances in large language models and agentic systems have created new security challenges by making it easier to detect and exploit software vulnerabilities. The report said mentions of agentic systems being involved in cyber events had increased since its May edition, but gave no count.
APRA’s November 12 System Risk Outlook addresses Australia’s financial system. It said frontier models, including those from Anthropic and OpenAI, are improving at finding and exploiting software flaws. APRA said few institutions had tested how they could switch away from critical AI providers. Its planned 2027 stress test will examine AI-driven economic disruption; it is a separate supervisory exercise from the Fed’s survey.
Limits of the Survey and Risk Data
The Fed survey represents 23 unnamed market contacts, not a poll of all financial institutions or a measured probability that a crisis will occur. The report does not identify the respondents or provide a statistical margin of error. Its survey section explicitly says the views should not be taken as the Fed’s institutional position.
The report’s information cutoff was October 28, 2026, so the survey and assessment do not capture developments after that date. The report also does not quantify how much of the cited bank exposure could be lost in a downturn, or estimate the likelihood or scale of disruption from an AI-linked cyber event. APRA’s outlook identifies provider-switching gaps but does not, in the material described, quantify the potential financial effect of a provider outage.
What the 2027 Test Will Examine
APRA says its 2027 System Stress Test will examine AI-driven economic disruption. The regulator has not, in the information cited here, set out the test’s detailed scenarios, participating institutions, schedule or results. Those details will be needed to understand how the planned exercise measures risks from cyber incidents, AI use and reliance on shared providers.
The Fed’s November report is a snapshot of its latest survey and financial-stability assessment, not a forecast of a specific event. Further reports and supervisory work may clarify how institutions are addressing AI-related cyber threats, financing exposures and their ability to replace critical vendors. For now, the confirmed development is that AI has moved to the top of the survey’s listed concerns while regulators are examining how disruptions could spread through connected firms and services.
Key Questions
What did the Fed survey find about AI?
87% of 23 market contacts surveyed in September and October named AI as a risk to U.S. financial stability. The comparable figure in the spring survey was 50% of 20 contacts.
Does the survey mean the Fed predicts an AI-driven crisis?
No. The survey records the views of market contacts, and the report says those views do not represent the Fed’s position. It identifies concerns rather than predicting that a crisis will occur.
What AI risks did respondents identify?
They cited possible corrections in AI-related stock valuations, AI-enabled cyberattacks and unintended damage from frontier models, as well as risks from complex AI-related financing.
What is Australia’s APRA planning?
APRA says its 2027 System Stress Test will examine AI-driven economic disruption. It has also raised concerns about frontier models’ ability to find software flaws and institutions’ limited testing of alternatives to critical AI providers.
