FTSE 100 Update, Dec 2: London Dips as BoE Warns of AI Valuation Risks

The FTSE 100 slid today as London markets reacted to fresh warnings from the Bank of England (BoE) about the risk of inflated valuations in AI-linked technology stocks. Global investor concern over an “AI bubble” and potential market correction rippled through UK equities, leading to a broad-based downward move.

Weakness across several sectors, including miners, retail, and discretionary names, compounded the drop, even as UK banks remained resilient in recent stress-test results.

This dip serves as a reminder that global markets are tightly linked: when US tech valuations tremble, the FTSE 100 feels the shock.

Why BoE’s AI warnings are affecting the FTSE 100

BoE warns of over-valuation in AI and tech stocks

In its latest Financial Stability Report, the BoE cautioned that valuations in many AI and technology firms appear “stretched”, at levels comparable to pre-dotcom bubble peaks. 

Because many global indices now have heavy weighting toward US tech, a drop there can send shockwaves across global equity markets, including in London. The BoE warned that if investor sentiment sours, a sharp correction could follow, potentially dragging markets like the FTSE 100 down.

Why does a US-tech drop matter for UK stocks?
Global funds and institutional investors often rebalance portfolios across regions. A slump in US tech prompts repositioning globally, which can hit UK equities, including FTSE 100 constituents.

Which FTSE 100 sectors are most exposed

Miners and commodities hit by global risk aversion

Miners and commodity producers, often valued as risk assets, saw some of the steepest losses as risk aversion took hold. Investors moved away from cyclicals toward perceived safe havens.

Financials and domestic-focused firms show relative resilience

Banks and firms with domestic exposure fared better, thanks to reassuring results from UK bank stress-tests and the BoE’s decision to relax certain capital rules. That stability helped prevent a steeper decline in the FTSE 100 overall.

Investors appear to retreat from internationally exposed firms and shift toward more UK-centric, lower-volatility companies during this climate.

Broader economic backdrop — UK housing and consumer trends

Beyond equities, the UK housing market delivered mixed signals today. The latest data shows home-price inflation easing in November, yet prices still rose modestly month-on-month.

This cooling property market adds to economic uncertainty, especially as consumers and households watch borrowing costs and inflation.

Does softening house-price growth affect the FTSE 100?
Indirectly yes. Slower house-price growth can reduce consumer spending and dampen confidence in sectors like retail, property, and financial services, areas that feed into the FTSE 100’s health.

Market sentiment and global caution — ripple effects from AI concerns

Investment funds shift away from US-centric tech exposure

Amid BoE warnings, several UK pension funds and institutional investors publicly disclosed moves to scale back US-equity holdings, particularly AI-heavy tech stocks.

Some funds are rebalancing portfolios toward UK stocks, bonds, or other geographies, a shift that could offer short-term support to domestic indices but also signals risk aversion at a global level.

Investors brace for volatility and potential corrections

With technology valuations high and global economic uncertainty, many investors expect increased market swings. Analysts warn that any negative surprise, weak earnings, poor AI-tech performance, or geopolitical or credit stress could trigger sharp corrections. 

This fear is not limited to equities: volatility in bond markets, rising interest rates, and currency fluctuations may all contribute to further pressure on global and UK markets.

What investors should watch next?

Key signals — interest rates, corporate earnings, and AI developments

Investors should watch for decisions by the Federal Reserve, global bond yield movements, and corporate earnings from technology and commodity firms. Weakness in any of these areas could spread to the FTSE 100.

UK economic data — house prices, inflation, consumer demand

UK-specific data such as inflation, employment, consumer spending, and house-price movement will matter: stronger data could shore up domestic stocks, while weak data may hurt them.

Market sentiment and global risk appetite

Because the FTSE 100 is linked to global investor flows, global risk sentiment, including confidence in AI, geopolitical events, and liquidity conditions, will play a major role in near-term performance.

Could the FTSE 100 bounce back quickly?
Yes: if central banks stabilise yields, earnings are solid, and risk sentiment improves, especially with cooling tech stocks, the FTSE 100 could recover some losses.

Conclusion

Today’s pullback in the FTSE 100 reflects a broader wave of caution across global markets, driven by warnings from the Bank of England about potentially inflated AI valuations. With technology stocks under scrutiny, investors are retreating from high-risk, high-reward sectors and seeking stability in reliable UK-based firms.

The mix of global risk aversion, softening housing market signals, and macroeconomic uncertainties has cast a shadow over London equities, but also offered a moment of reset. For patient investors, this dip may present selective opportunities in domestic-focused and financially stable sectors.

Moving forward, the interplay between global AI valuations, bond markets, and UK domestic economic data will define the trading environment for the FTSE 100. For now, stability, caution, and smart stock picking seem more important than chasing high-flying gains.
