The UK stock market traded slightly lower on Thursday as investors digested Chancellor Rachel Reeves’ hefty Autumn Budget, with energy, miners and consumer staples weighing on the blue‑chip FTSE 100 while mid‑caps held on to modest gains.
By late morning in London, the FTSE 100 was down around 0.2–0.3% and hovering near 9,670, pulling back from Wednesday’s strong post‑budget rally that took the index to roughly 9,692, an 0.8% gain on the day.Reuters+2Investing.com+2 The more domestically focused FTSE 250 was modestly higher, up between 0.1% and 0.4%, as traders rotated into UK‑centric growth stories and budget beneficiaries.Reuters+1

Indices at a glance: a budget hangover for blue chips
The tone on Thursday is very much a “budget hangover” rather than an outright sell‑off:
- FTSE 100: down about 0.3%, pressured by energy, miners and consumer staples.Reuters
- FTSE 250: up around 0.1–0.4%, holding onto part of Wednesday’s near 1% surge after the budget.Reuters+2MoneyWeek+2
- Previous session: the UK’s main equity benchmark closed near 9,692 points on 26 November, up 0.85%, as markets initially welcomed extra fiscal headroom and a calmer gilt market.Trading Economics+2Reuters+2
Global risk sentiment is broadly supportive. European shares are slightly higher and global equities have been buoyed by rising expectations of a US Federal Reserve rate cut in December, even as US trading pauses for the holiday.Reuters Yet the UK stands out today because of the domestic policy shock delivered in Reeves’ second budget.
Budget 2025: “live now, pay later” taxes meet a cautious market
Reeves’ Autumn Budget, delivered on Wednesday, is one of the most aggressively tax‑raising packages since 2010. According to the Office for Budget Responsibility (OBR), the measures will add about £26 billion in extra annual tax revenue by 2029/30, lifting the overall tax burden to around 38% of GDP by 2030/31 – an all‑time high.MoneyWeek+1
Key revenue‑raisers include:MoneyWeek+2Weil Tax BLOG+2
- Extended freeze on income tax thresholds to 2031, expected to raise more than £8 billion a year by the end of the decade.
- National Insurance on salary‑sacrifice pension contributions, forecast to add roughly £4.7 billion by 2029/30.
- Higher tax rates on property, savings and dividends income, plus reforms to ISAs.
- A new “mansion tax”–style boost to property taxation at the high end of the housing market.
- Sharp increases in gambling duties (more on that below).
Markets initially liked the fiscal headroom – roughly £22 billion of buffer versus Reeves’ own fiscal rules, up from about £10 billion previously – and gilt yields fell in the immediate aftermath.Reuters+2MoneyWeek+2 But analysts have been quick to point out that the budget is heavily back‑loaded, with tax hikes and spending restraint concentrated in the later years of the forecast horizon.
Guardian columnist Larry Elliott described it as a “live now, pay later” package: spending increases up‑front, with most of the tax pain arriving closer to the next election. Markets welcome the bigger rainy‑day fund, he argues, but are already questioning how credible future consolidation really is.The Guardian
That scepticism helps explain why Thursday’s reaction is more muted. The UK has avoided anything resembling a “mini‑budget” crisis, but investors are recalibrating which sectors win or lose as the details sink in.
Sector story: energy, miners and defensives drag the FTSE 100
The FTSE 100’s decline today is not broad‑based – it’s driven by a fairly tight cluster of sectors.Reuters+1
Energy and commodities
- Major energy names fell as the oil price slipped, partly on hopes of progress toward a ceasefire in the Ukraine‑Russia conflict, which would ease some geopolitical risk premium.Reuters+1
- BP shares were down about 1.2%, while the FTSE 100’s energy sub‑index dropped close to 0.9%.Reuters
- Industrial miners such as Anglo American and Rio Tinto lost more than 1.5% each, reflecting weaker commodity prices and global growth concerns.Reuters
Consumer staples and personal goods
Defensive stalwarts – usually safe havens in uncertain times – came under pressure:
- Unilever slipped around 0.7% and British American Tobacco roughly 1.2%.
- Luxury and personal goods were also underperformers, with Burberry down about 1.7%.Reuters
These stocks are sensitive to long‑term UK growth and disposable income expectations. The budget’s reliance on stealth taxes via frozen thresholds is seen as a slow squeeze on the middle‑income consumer, which weighs on sentiment toward high‑ticket discretionary brands.MoneyWeek+1
Pockets of strength: precious metals and homebuilders
Not everything is gloomy:
- Precious‑metal miners gained about 0.7%, with Endeavour Mining up about 1.2%, helped by firm gold prices and the continuing role of bullion as a hedge in a world of stubborn inflation and political noise.Reuters+1
- Homebuilders rebounded nearly 0.9% after being hit on Wednesday by higher property taxes. Investors seem to be reassessing the damage, perhaps viewing the reforms as manageable given falling mortgage rates and the possibility of Bank of England rate cuts next year.Reuters+2The Guardian+2
Gambling tax shock: Evoke, Rank and Flutter in the line of fire
The biggest single sector story of the day is gambling. Reeves’ budget sharply raises duties on online gaming:
- Remote gaming (online casino / slots): tax rate jumps from 21% to 40%.
- Sports betting: from 15% to 25%.Reuters+2Reuters+2
This is a seismic change for a sector that was already grappling with tighter regulation and affordability checks.
A dedicated Reuters piece on Thursday set out the damage:
- Evoke – owner of William Hill UK and 888 – dropped around 6–7% after warning the tax hike would squeeze profitability and forcing it to withdraw medium‑term targets while it revisits investment plans.Reuters
- Rank Group fell about 10%, having estimated a £40 million annual profit hit from the new duty, with its casino and bingo halls particularly exposed.Reuters
- Flutter Entertainment, the FTSE 100 betting giant behind Paddy Power and Sky Bet, has said the new UK tax regime could reduce its adjusted EBITDA by roughly $320 million in 2026 and $540 million in 2027 before mitigation, though it expects to offset part of that through cost cuts and market share gains.Reuters+2London South East+2
Analysts generally agree that larger, more diversified operators such as Flutter and Entain are better placed to absorb the blow, while smaller or UK‑concentrated players like Evoke and Rank face far tougher choices.Reuters+1
The sector’s slump is one of the clearest examples of how policy risk – tax and regulation – can quickly override pure macro or valuation stories in the UK market.
Mid‑caps: Pennon leads gainers as earnings and budget tailwinds mix
While mega‑caps sulk, mid‑cap investors are having a more cheerful day.
Pennon Group: water, profits and hot weather
On the FTSE 250, Pennon Group – the owner of South West Water – is among the top performers after reporting a swing back to profit in the first half.MarketScreener+2Share Prices+2
Highlights from the half‑year update include:
- Revenue up about 25% year‑on‑year to roughly £658 million, driven by higher bills and strong water demand over the hot summer.
- Underlying pre‑tax profit of around £65.9 million, versus a loss of £18.6 million a year earlier.
- Guidance pointing to a 60% rise in underlying EBITDA for the full 2026 financial year compared with 2025.
Shares in Pennon were up roughly 3–4%, putting the group near the top of the FTSE 250 leaderboard.MarketScreener+2Morningstar+2
Other FTSE 250 movers
Data from London open reports and intraday rankings show a cluster of consumer and infrastructure names among the day’s early winners:MarketScreener+2Vox Markets+2
- Playtech up around 8–9%, bouncing despite acknowledging it, too, faces higher UK gambling duties.
- Watches of Switzerland, Raspberry Pi Holdings, British Land and IP Group all gained roughly 3–5%.
- Close Brothers and Ceres Power were also higher, suggesting a modest rotation into cyclicals and UK financials after the budget calmed immediate gilt‑market nerves.
On the downside, mid‑cap laggards include Rank and Unite Group, both hurt by budget‑related themes – gambling taxes for the former and a downbeat outlook in student housing for the latter.Reuters+1
Sterling, gilts and the Bank of England: rate‑cut bets firm up
The currency and bond markets provide a useful reality check on how seriously investors are taking the UK’s new fiscal stance.
- On Wednesday, after the budget and the OBR’s relatively upbeat forecasts, sterling climbed about 0.3% to roughly $1.3213 and 10‑year gilt yields fell around 4 basis points to 4.46% as prices rose.Reuters+1
- By Thursday morning, the pound had eased back slightly, down about 0.15% to $1.3222, as the dollar firmed on expectations of a Fed rate cut – but there was no sign of a confidence crisis.Reuters
A Guardian live blog summarised the post‑budget consensus:
- Markets broadly welcomed the extra headroom and the absence of shock-and-awe rate hikes or wild spending promises.
- Think‑tanks such as the IFS and Resolution Foundation criticised the “fiscal fiction” of back‑loaded tax hikes and warned that freezing thresholds hits lower‑income workers hardest.
- Several economists argued that the budget has actually increased the likelihood of a Bank of England rate cut in December, given that inflation is expected to fall further next year while fiscal policy tightens gradually.The Guardian+1
In parallel, the UK Debt Management Office signalled plans to consult on expanding the Treasury bill market to meet rising demand from institutions including stablecoin issuers, and to keep the investor base for UK government debt broad and resilient.The Edge Malaysia That’s another sign that the authorities are keen to avoid another gilt‑market accident like the one triggered by 2022’s mini‑budget.
Structural tweaks for equity investors: ISAs, listing relief and more
Beyond the headline tax rates, several technical changes in the budget matter directly for UK equity investors.
ISA reforms
MoneyWeek’s analysis highlights a significant shift in cash ISA rules:MoneyWeek
- From 6 April 2027, savers under 65 will only be able to hold £12,000 per year in a cash ISA within the existing £20,000 overall ISA allowance; the rest must go into stocks and shares or other investment ISAs.
- Over‑65s retain the full £20,000 cash ISA allowance.
Combined with frozen tax thresholds and upcoming hikes in tax on savings income, ISAs become more important as a tax shelter for investments, potentially nudging more UK households towards equity markets in the medium term.
Listing relief for newly listed shares
Tax specialists note that the budget also introduces a new exemption for certain newly listed shares on or after 27 November 2025, part of a package of reforms to stamp duty and the UK listing regime.Weil Tax BLOG
The details are highly technical, but the policy aim is clear:
Make the London Stock Exchange a more attractive venue for new listings by trimming transaction frictions and modernising the stamp tax framework.
For a market that has watched a steady drip of UK companies de‑list or seek foreign IPOs in recent years, any credible nudge toward re‑onshoring listings is a structural positive, even if the immediate price impact is small.
What today’s moves mean for UK equity investors
Today’s session underlines a few themes that are likely to define the UK stock market in late 2025 and into 2026:
- Policy risk is real and sector‑specific
Gambling operators have just been reminded that tax and regulatory decisions can reshape profitability overnight. Similar risks exist for utilities, banks, tech and energy, especially as governments hunt for revenue and try to manage climate and social goals. - Back‑loaded austerity keeps growth skepticism alive
Reeves has earned some short‑term credit in the bond market, but the heavy reliance on future tax hikes means UK growth forecasts remain fragile, which caps how far valuations can rerate without clear productivity improvements.Reuters+2The Guardian+2 - Mid‑caps remain the “pure play” on domestic resilience
The FTSE 100 is still dominated by global commodity, energy and consumer giants, which trade more on world growth and dollar trends than on UK politics. The FTSE 250 – with names like Pennon, British Land, Watches of Switzerland and Raspberry Pi – is more directly linked to how the UK economy and the new tax regime actually evolve.MarketScreener+2Vox Markets+2 - Central bank and fiscal policy are now tightly intertwined
The budget has slightly nudged markets toward expecting a December Bank of England rate cut, but that depends on incoming inflation data and how credible the OBR’s growth projections prove to be. A mis‑step on either front would quickly show up in gilt yields and, by extension, equity valuations.Reuters+2The Guardian+2
For now, there is no sign of panic in Thursday’s session. The story is more subtle: a market recalibrating winners and losers in light of a historically tax‑heavy budget that promises stability today at the cost of higher future burdens.
As more companies quantify the impact of Reeves’ measures in trading updates over the coming weeks, UK equities will keep repricing – sector by sector – around one central question: is the new fiscal path compatible with the growth the UK needs?
