Bank of England governor Andrew Bailey warned on Tuesday that the surging flow of capital into artificial‑intelligence ventures could generate financial‑market turbulence if left unchecked.

AI investment hits record levels

Venture‑capital funds, corporate balance sheets and sovereign wealth portfolios have poured unprecedented sums into AI start‑ups and technology providers this year, according to data from industry analysts. Generative‑AI platforms, specialised chip manufacturers and cloud‑service providers have all seen share prices climb sharply, with a handful of AI‑focused exchange‑traded funds posting double‑digit gains in recent weeks.

"We are watching the waves of cash being invested in artificial intelligence very carefully," Bailey told a parliamentary finance committee.

That influx has lifted the technology sector’s market capitalisation to its highest point since the early 2020s, prompting analysts to question whether the rally reflects genuine productivity gains or a speculative surge.

Bailey said the Financial Policy Committee is assessing whether the rapid build‑up of AI‑related assets could amplify systemic risk. He highlighted three channels of concern: inflated valuations of AI‑centric firms, heightened exposure of banks and insurers to a sector still in its infancy, and the possibility that a sudden correction could spill over into broader credit markets.

The central bank is reviewing its macro‑prudential toolkit, including the potential to tighten capital buffers for lenders with sizable AI‑exposure. "We will act if we see evidence that the build‑up of risk is becoming material," Bailey added, underscoring the BoE’s readiness to intervene.

Context and likely impact

The warning arrives as policymakers worldwide grapple with the economic implications of AI. The US Federal Reserve and the European Central Bank have both signalled heightened vigilance, noting that the technology’s productivity promise is matched by uncertainty over its financial‑system effects.

Historically, rapid technology‑driven investment cycles have produced sharp corrections – the dot‑com bust of the early 2000s being the most prominent example. While AI differs in scope and application, the pattern of speculative inflows followed by market realignment offers a cautionary parallel.

For investors, Bailey’s remarks suggest a shift from unbridled enthusiasm to more measured scrutiny. Asset managers may re‑evaluate exposure to AI‑centric equities, and lenders could tighten underwriting standards for firms seeking AI‑related financing.

Companies developing AI solutions are likely to face increased demand for transparent risk reporting, as regulators seek early signals of overheating. The BoE’s proactive stance signals that the sector’s growth, while welcome for its innovation potential, will be closely tracked for any signs of financial‑system strain.
