The Federal Reserve has identified artificial intelligence as its primary concern for financial stability, surpassing traditional risks like inflation and banking sector vulnerabilities.
In its semi-annual Financial Stability Report released November 13, 2026, the US central bank reported that 87% of surveyed contacts flagged AI as a salient risk to the financial system. This made AI the most-cited concern on the list, ahead of all other threats.
The jump in concern is significant. In the May 2026 edition of the same survey, only 50% of respondents identified AI as a risk. Within six months, that proportion climbed to 87%.
Debt and valuation concerns
The Fed's respondents cited multiple AI-related vulnerabilities. Concerns included stretched equity valuations, the risk that earnings fail to match expectations and trigger a market correction, and cybersecurity weaknesses tied to advanced AI systems.
The report quantified spending in the sector. Debt issuance tied to advanced computing reached $680 billion by October 2026, representing nearly one-third of nonfinancial investment-grade corporate debt issuance. Three years earlier, that share was less than 6%.
The potential future commitments are larger still. The Fed noted that debt, guarantees, and leases on AI infrastructure not yet commenced could exceed $3 trillion.
The scale of investment has drawn comparisons to the late-1990s broadband cycle, when companies invested heavily in network capacity ahead of actual demand.
Other financial stability risks
AI topped the survey, but other concerns registered significant support among respondents. A broad correction in risk assets was cited by 52%, while elevated long-term interest rates appeared in 48% of responses. Respondents also highlighted fiscal sustainability concerns, noting that US federal debt now exceeds $40 trillion, and cybersecurity threats separate from AI-specific risks.
The International Monetary Fund's October 2026 report raised similar alarms about risks tied to AI-driven market dynamics.
Market implications
For investors and regulators, the concentration of high-grade corporate borrowing in AI-related infrastructure presents a systemic concern. When nearly one-third of investment-grade debt issuance ties to a single sector, that sector's financial performance can ripple through broader credit and equity markets.
The Fed's next Financial Stability Report, due in approximately six months, will indicate whether these concerns continue to rise or begin to moderate. Key indicators to track include the pace of new AI-linked debt issuance and whether the potential $3 trillion in uncommitted infrastructure obligations begins converting into actual debt obligations.
