Citi has downgraded UK equities from ‘overweight’ to ‘underweight’, arguing that the FTSE’s traditional strengths have become less compelling as global market leadership broadens beyond defensive sectors. The move marks a notable shift from one of the investment banks that had previously been constructive on the UK market.
Citi’s central argument is that the investment backdrop has changed.
Earlier in 2026, UK shares benefited from their heavy exposure to defensive industries such as pharmaceuticals, consumer staples, oil majors and mining companies. Investors also viewed the FTSE 100 as something of a geopolitical safe haven during heightened tensions in the Middle East.
Now, Citi believes that appeal is fading.
Instead, it expects improving global earnings growth to favour more cyclical and growth-oriented markets, particularly those with greater exposure to technology, industrials and AI investment. That has led Citi to rotate away from the UK and towards markets such as Japan while maintaining an overweight position in US equities.
Key index performance 2026
| FTSE 100 YTD | ~8.1% | S&P 500 YTD | ~11.6% |
| FTSE 250 YTD | ~6.0 | FTSE All-World YTD | ~12.2% |
Importantly, Citi is not arguing that UK shares are expensive.
In fact, it notes the FTSE 100 trades on around 12.2x forward earnings, making it one of the cheapest developed equity markets. Rather, its view is that cheap valuations alone are unlikely to outperform if investors increasingly reward stronger earnings growth elsewhere.
Citi still sees opportunities
The downgrade is not a wholesale rejection of UK equities.
Within the UK market, Citi continues to favour:
| Preferred sectors | Why |
| Banks | Improving earnings outlook and attractive valuations |
| Basic Resources | Commodity exposure remains supportive |
| Healthcare | High-quality global businesses despite sector downgrade globally |
It also continues to prefer the internationally focused FTSE 100 over the more domestically exposed FTSE 250, given lingering uncertainty around the UK economy.
The counter argument
Many investment strategists remain constructive on UK shares for several reasons.
1. Valuations remain exceptionally attractive
The UK continues to trade at a sizeable valuation discount to both US and global markets.
If global growth merely meets expectations rather than accelerates sharply, investors could once again be drawn towards these cheaper cash-generative businesses.
2. Dividend income remains a major attraction
The FTSE 100 continues to offer one of the highest dividend yields among developed markets.
For ISA and SIPP investors seeking long-term income, that remains an important advantage that isn’t captured by short-term tactical calls.
3. Global exposure is often underestimated
Despite being labelled a ‘UK’ index, roughly three-quarters of FTSE 100 revenues are generated overseas.
Investors buying companies such as global pharmaceutical firms, consumer goods groups, mining companies or energy majors are often gaining exposure to worldwide rather than purely British economic growth.
4. AI concentration risk
Some strategists also argue that investors have become heavily concentrated in US technology shares.
Maintaining meaningful UK exposure can provide valuable diversification if enthusiasm around AI-related stocks cools.
What other analysts think
Citi’s downgrade is far from universally shared. While it argues the UK’s defensive characteristics are becoming less attractive as global earnings growth broadens, other strategists continue to see compelling reasons to remain invested.
Bullish: UBS – Europe still has room to run
UBS recently raised its year-end target for the STOXX Europe 600, arguing that the European earnings outlook continues to improve thanks to AI-related upgrades, resilient bank profits and the fact that defensive sectors are no longer acting as a drag on overall market performance. Although UBS’s call is Europe-wide rather than UK-specific, it is supportive of many sectors that dominate the FTSE 100, including banks and mining companies.

Bullish: Barclays – Stay globally diversified
Barclays continues to advocate broad global equity exposure rather than making aggressive regional bets. Its strategists argue that timing short-term market leadership is difficult and that investors are generally better served by maintaining diversified portfolios across regions and sectors.
The structural bear case
Other strategists broadly share Citi’s longer-term concern that the UK market lacks exposure to the world’s fastest-growing industries.
The FTSE 100 remains structurally underweight sectors that have driven most global equity returns over the past decade:
- Large-cap technology
- AI infrastructure
- Software
- Digital platforms
- Semiconductor companies
Instead, it remains dominated by banks, energy, miners, healthcare and consumer staples.
If AI-led capital spending continues driving global earnings growth, the UK could continue lagging US and some Asian markets despite trading on much cheaper valuations. That has been one of the defining themes of the past decade and remains the principal argument for favouring US equities over the UK.
Should UK retail investors reduce exposure?
For most long-term retail investors, Citi’s note probably argues against overweighting UK shares rather than abandoning them altogether.
Investors should remember that tactical calls from investment banks typically reflect expected performance over the next 6-12 months, whereas ISAs and pensions are usually built over decades.
Best/worst FTSE 100 YTD performers
| Beazley | +54.7% | Entain | -28.2% |
| Schroders | +44.5% | Barratt Redrow | -27.0% |
| DCC | +36.7% | Fresnillo | -23.4% |
| Bunzl | +29.7% | Persimmon | -22.7% |
| Hiscox | +29.5% | Melrose Industries | -22.5% |
For UK investors, a balanced approach still appears sensible:
- Maintain UK exposure for dividends, valuation support and diversification.
- Ensure sufficient overseas exposure, particularly to US technology and global growth companies.
- Avoid concentrating too heavily in either UK defensives or expensive US AI winners.
Investor verdict
Citi’s downgrade highlights a genuine risk: if global earnings growth broadens and investors continue rewarding cyclical and technology-led markets, the UK’s defensive composition may underperform.
However, the UK’s low valuations, attractive dividend yields and globally diversified multinational companies continue to provide a compelling long-term investment case. Rather than signalling that investors should exit UK equities, Citi’s move is perhaps better viewed as a reminder to avoid excessive home bias.
That means the debate is less about whether UK equities are good or bad, and more about what role they should play within a portfolio.
Reasons to reduce UK exposure
- Global earnings leadership is shifting towards technology and AI.
- The FTSE has relatively little exposure to structural growth sectors.
- Cheap valuations can remain cheap if earnings growth disappoints.
Reasons to keep meaningful UK exposure
- The FTSE 100 remains one of the cheapest major developed markets.
- Dividend yields are significantly higher than those available in the US.
- Around three-quarters of FTSE 100 revenues come from overseas, providing global rather than purely domestic exposure.
- Banks, miners and healthcare companies could continue to perform well if the global economy remains resilient.
For many UK retail investors, while the FTSE’s traditional strengths may have become less compelling, the stronger conclusion is not to own less UK, but to ensure it forms just one component of a globally diversified portfolio that can benefit from both value opportunities at home and structural growth overseas.
