What happened

The rapid rise of artificial intelligence is creating new financial stability risks, the head of the Bank for International Settlements, Pablo Hernandez de Cos, said on Thursday reuters.com ground.news. He warned that the fast growth of debt-financed artificial intelligence investment could pose systemic risks, and pointed to the opacity of the debt behind the capital-spending race coindesk.com.

Bloomberg reported his assessment that the arms race remains a global financial stability danger, one that risks more damage than past crashes bloomberg.com. The BIS published the speech, in which he also set out the other side of the ledger: AI has the potential to increase productivity significantly over the coming years, and the recent empirical evidence for that is compelling bis.org. Speaking at Global Fintech Fest 2026, he said AI could reshape monetary policy and financial stability alike, and that central banks need global cooperation on cyber risk bfsi.economictimes.indiatimes.com.

Why it matters to investors

The BIS is the institution central banks use to compare notes, so its framing tends to precede supervisory attention. The claim being made is narrow and specific: the risk sits in how the build-out is funded rather than in whether the technology works coindesk.com bis.org.

That distinction matters for anyone holding the credit rather than the equity. A capital-spending cycle financed through instruments that supervisors describe as opaque is harder to size from outside, and the BIS view is that the resulting exposure has grown large enough to register at the level of the system, not just the sector coindesk.com reuters.com. Other coverage of the remarks framed them as a warning that the investment surge is creating new risks for markets beninwebtv.bj.

What to watch

Two threads run out of the speech. The first is supervisory: whether national regulators start asking for disclosure on the structures behind AI-related borrowing, which is the practical consequence of calling that debt opaque coindesk.com reuters.com.

The second is monetary. Hernandez de Cos linked AI to the conduct of monetary policy itself, not only to stability, which puts productivity assumptions inside the rate-setting debate rather than outside it bfsi.economictimes.indiatimes.com bis.org. He paired the stability warning with a claim about significant productivity gains, and the two are not in conflict: a build-out can raise output and still be financed in a way that transmits stress bis.org bloomberg.com. For investors the near-term test is whether other central banks echo the framing in their own financial stability reviews reuters.com ground.news.
