BOE flags AI risks

Highlights

Bank of England's stability review warns that rising investor bets and high leverage in AI-linked sectors heighten financial stability risks due to possible repricing.
Central bank highlights rapid growth of AI's destructive capacity, heavy company debt, and poor borrowing transparency as new risk factors since its last half-year assessment.
Despite current resilience, Bank of England proposes easier capital buffer use and signals need for bespoke AI regulation to address cyber and operational threats from advanced autonomous systems.

AI-related threats in the latest stability review

As reported by Reuters, citing the Bank of England, its half-yearly assessment says artificial intelligence is becoming a growing threat to financial stability as investors place heavy bets on the technology and banks face greater vulnerability to cyberattacks.

The central bank says risks previously identified from stretched share price valuations, high public debt and risky private credit lending to businesses remain in place. Since its last report, it also highlights added dangers from investors, including hedge funds, borrowing to buy shares, AI-related companies taking on heavy debt to fund investment and the rapid expansion of AI's capacity to cause harm.

The Bank of England says successful investor bets on AI depend on widespread profitable adoption of the technology, effective construction of new infrastructure and continued easy access to finance. It warns that any reassessment of those prospects could trigger a drop in equity prices, with losses amplified by concentrated positions, momentum-driven trading and higher leverage.

It also says the future earnings potential of AI-related companies is important to the sustainability of their debt, adding that poor transparency around borrowing could worsen any market stress.

Implications for banks, regulation and resilience

Despite the added concerns, the Bank of England judges that Britain's banking system remains resilient. It also sets out proposals to make it easier for banks to run down capital buffers after a crisis so they can sustain lending to the wider economy.

Global regulators are focusing more closely on AI's impact, including cyber and operational risks linked to frontier models and the challenges created by agentic systems that can act with limited human intervention. At the end of June, Deputy Governor Sarah Breeden signals for the first time a need for bespoke AI regulation to contain risks from increasingly capable autonomous systems.

In the latest report, the central bank says it remains unclear whether more powerful AI ultimately benefits attackers or defenders of financial systems more. It adds that financial firms are likely to need more frequent software updates, which may themselves create operational disruption risks.

In our earlier article on SoftBank’s expanding AI financing, we examined how the group is using gains from its Arm stake and additional borrowing to fund large bets on OpenAI and global data-centre buildouts. We also noted investor concerns about valuation sensitivity and leverage, as a market downturn could quickly erode the cushion supporting these AI-linked investments.
