Bank of England Warns of Risk of Sharper Correction in AI Valuations
nashnova research
The Bank of England warned in its quarterly financial stability report that AI valuations risk a selloff bigger than July's, one that could ripple into sovereign bond markets and global growth expectations — no longer a tech-sector problem alone.
What exactly is the Bank of England worried about?
AI valuation risk is now a headline warning: growth forecasts in multiple economies already price in the assumption that AI will boost productivity.
This means → if markets reassess that assumption, the damage won't stop at AI stocks — sovereign debt markets will come under pressure too.
In plain terms = governments have baked "AI-driven growth" into how their bonds are priced; if that expectation fades, bond yields move as well.
The BoE also flagged a fresh escalation in the Middle East as a key risk, warning it could deliver "a more persistent negative supply shock" that pushes sovereign bond risk higher.
Why didn't July's AI selloff cause wider damage?
The report noted that July's AI market correction was amplified by "unwinding of concentrated positions and associated deleveraging."
But the shock "did not spread to core markets" — losses stayed largely within tech-heavy portfolios.
This means → the BoE's concern is not a repeat of July but that the next correction's transmission path could be wider, spilling from tech equities into bonds and credit.
What did Governor Bailey say about AI regulation?
Governor Andrew Bailey called AI's impact on financial stability "significant" and stressed the need to "rigorously test" AI capabilities to reduce cyber risk.
He stated explicitly: "Regulation is not, in my view, the right starting point" — understanding, testing, and building credible intervention points must come first; a formal framework "may emerge over time."
This reflects the BoE's current stance: map the terrain before writing the rules, rather than rushing to regulate.
What is new on credit markets and bank leverage?
The BoE noted that riskier credit markets, including parts of private credit, remain "vulnerable to a tightening in financing conditions", with risk-taking "elevated" in some areas.
Yet the bank confirmed support for easing the absolute leverage cap on banks, and said gilt-market leverage risk can be managed through market reforms set for consultation in early 2027.
It kept a backstop: if conditions shift, the bank leverage-ratio buffer can be raised by 25 basis points.
How do rate-hike expectations and AI valuations intersect?
UK gilt yields have risen in lockstep with global government bonds; elevated energy prices are fueling fears that the BoE may be forced to hike further.
Swap markets currently price the BoE starting hikes as early as November, with up to five cumulative hikes by end-2027.
This means → if rates keep climbing, higher funding costs squeeze households, businesses, and richly valued assets simultaneously — whether AI valuations can hold up under this macro backdrop is the market's next key test.
