London stocks head into the week of 15–19 December 2025 with one macro theme dominating everything else: the Bank of England’s December decision. After a week defined by a US rate cut, a surprise dip in UK GDP, and a late-week wobble tied to “AI bubble” nerves on Wall Street, the FTSE 100 and FTSE 250 now turn to a dense UK data run—labour market, inflation, and retail sales—plus a short but potentially market-moving corporate diary (including Currys, Bunzl, Hollywood Bowl, IntegraFin, and WH Smith). [1]
What happened last week in UK equities (8–12 December) — and why it matters now
The tone for the “week ahead” was set by how quickly sentiment swung between rates optimism and risk-off anxiety.
Monday (8 Dec): Central banks and the consumer set the mood
UK shares slipped as investors braced for the Federal Reserve and Bank of England decisions, with housebuildersamong the biggest laggards and Unilever weaker as the Magnum Ice Cream unit moved toward an Amsterdam listing as part of its separation. The same session also carried a reminder that the UK consumer remains under pressure—Aldi’s UK boss pointed to shoppers spreading the cost of Christmas by buying earlier and switching from meals out to dining in. [2]
Tuesday (9 Dec): Defence and metals up; consumer signals downbeat
London’s blue chips finished essentially flat, supported by precious metals miners and defence names. BAE Systems rose after a report suggested German lawmakers were set to approve record defence contracts, while Barclays’ card spending data highlighted a weak consumer backdrop. [3]
Wednesday (10 Dec): Banks take the lead ahead of the Fed
The FTSE 100 edged up with banks outperforming, helped by broker upgrades to lenders including HSBC and Standard Chartered. Outside the banks, the session also delivered stock-specific moves in FirstGroup (linked to a London Overground contract) and Evoke (strategic options review). [4]
Thursday (11 Dec): Fed cut lands; UK stocks rise but “AI angst” flickers
UK equities rose after the Fed cut rates by 25bp. Even with Wall Street wobbling on concerns about big-ticket AI investment, London saw strength in precious metal miners and selected UK names on upgrades and idiosyncratic news (including a notable drop in Ceres Power after a short position was disclosed). [5]
Friday (12 Dec): UK GDP disappoints, miners jump—then Wall Street spoils the party
Friday encapsulated the current market tension: UK stocks were initially buoyed by a surge in precious metal miners as gold and silver rallied, but the FTSE 100 ultimately closed lower as a Wall Street selloff—sparked by renewed worries about frothy AI expectations—hit risk appetite. The same day, UK-focused headlines mattered: UK GDP data showed the economy unexpectedly shrunk in the three months to October, reinforcing expectations of a BoE cut, while Card Factory issued a warning tied to weaker-than-expected store sales and concerns over footfall. [6]
The big catalyst: Bank of England decision on 18 December
What markets are expecting
The Bank of England’s next Monetary Policy Committee decision is due Thursday, 18 December, with the policy summary and minutes scheduled for 12:00 noon UK time. [7]
Across the coverage from 8–13 December, the consensus hardened:
- A 25bp cut to 3.75% is widely expected, according to a Reuters poll of economists. [8]
- Market pricing during the week repeatedly clustered around high odds of a December cut (figures cited ranged from the mid‑80s to around 90%, depending on the day and source). [9]
This expectation is anchored in three signals repeatedly cited by strategists and reporters:
- Cooling activity (underscored by the weak GDP print), [10]
- Signs of labour-market softening, [11]
- Disinflation progress—even if inflation remains above target. [12]
Why the BoE decision could still surprise markets
Even when a cut is “priced,” the vote split and guidance can be the real market mover.
- The BoE’s November decision was narrowly balanced (a tight vote is referenced repeatedly across analyst commentary), and Reuters highlighted how a previously split committee could flip toward easing as evidence mounts that inflation is drifting down. [13]
- BoE policymaker Alan Taylor argued on 8 December that inflation could return to the 2% target “in the near term,” citing slowing wage growth and services inflation—language that markets read as dovish. [14]
- Deutsche Bank’s view, cited by Investing.com, was that Governor Bailey may now have enough evidence of disinflation to back a cut—and that the MPC could also tweak forward guidance, potentially shifting away from a rigid “gradual” message toward a more data-dependent stance. [15]
In plain English: the cut may be the easy part. The harder part—and the piece that can jolt sterling, gilt yields, and UK bank/housebuilder shares—is what the BoE signals about the pace of follow‑up cuts into 2026. [16]
UK economic calendar: the three data releases that can move FTSE 100 and FTSE 250
The week’s UK data flow matters because it directly feeds expectations for how far and how fast the BoE eases, which in turn influences rate-sensitive sectors (banks, real estate, housebuilders, consumer credit) and the broader risk tone.
1) Labour market update — Tuesday, 16 December
Official labour-market and claimant-count data are scheduled for 16 December (with ONS series pages listing that date as the next release for key claimant count data). [17]
Why it matters for UK stocks:
- A weaker jobs picture supports the case for BoE easing, typically helping domestically sensitive mid-caps.
- But it can also reinforce “growth scare” narratives—bad news for cyclicals and discretionary retailers. [18]
2) UK inflation — Wednesday, 17 December
ONS release listings indicate the next UK CPI dataset update is due 17 December (confirmed in ONS release listings). [19]
Why it matters:
- Another step down would validate the “cut now” consensus and could pull gilt yields lower—often supportive for rate-sensitive equities.
- A sticky print (especially in services) would revive the debate about whether the BoE can keep cutting after December. [20]
3) UK retail sales — Friday, 19 December
ONS release calendar listings show Retail Sales; Great Britain: November 2025 is scheduled for 19 December (07:00am). [21]
Why it matters:
Retail was already a focus in last week’s market action: Card Factory’s warning and consumer spending commentary kept attention on footfall and discretionary demand into Christmas. Retail sales data late in the week could therefore amplify (or ease) pressure on UK-focused consumer names. [22]
Global drivers London investors are watching alongside UK data
Even in a UK-centric week, global macro sets the “risk-on/risk-off” backdrop for the FTSE—especially when cross-asset moves are being driven by AI sentiment, the dollar, and bond yields.
- The Fed’s 25bp cut landed mid-week, but markets also absorbed mixed messaging about how quickly easing continues—one reason UK traders saw volatility spill over from Wall Street late in the week. [23]
- S&P Global’s week-ahead preview flagged a heavy global calendar including multiple central bank meetings and major data releases, with UK PMIs and inflation part of the mix that policymakers will see before the BoE decision. [24]
- IG’s week-ahead note highlighted a rotation away from technology into cyclicals/value and pointed to AI capex worries as a key theme, a dynamic that can influence London via sentiment, commodities, and index sector weightings. [25]
For UK investors, the practical takeaway is this: if US tech volatility accelerates again, the FTSE 100 can still be pulled around even when the UK calendar is packed—especially via risk appetite and commodity-linked flows. [26]
Corporate calendar: fewer results, but still plenty of stock-specific risk
With Christmas approaching, the corporate diary thins out—but several names can still create meaningful single-stock volatility (and occasionally pull sectors with them).
Results and trading updates to watch (week of 15 Dec)
- Hollywood Bowl (full-year results) and SThree (trading update) are among the UK releases highlighted for Tuesday. [27]
- Bunzl is set for a pre-close/trading statement mid-week, with IntegraFin also due to report. [28]
- Currys is scheduled to report interim numbers on Thursday, placing UK consumer electronics demand and margin commentary under the microscope. [29]
- Carnival is among the late-week global reporters on some UK market diaries, offering a read-across for travel demand and discretionary spend. [30]
The WH Smith situation remains a headline risk
WH Smith is the notable “special situation” going into the week. The company delayed its annual results again, now expecting to publish on 19 December, as auditors complete procedures tied to an accounting review at its US operations. [31]
For the broader market, the WH Smith story matters less for index points and more for sentiment around governance, audits, and reporting quality, particularly heading into year-end positioning. [32]
Sector watch: what the FTSE is really trading right now
Banks: caught between rate cuts and confidence
UK banks led gains earlier in the week on upgrades and rate positioning. But into the BoE decision, investors will be weighing two competing effects: rate cuts can ease credit stress and support loan demand, yet they can also compress net interest margins over time. [33]
Miners: gold and silver momentum is back in focus
Precious metal miners surged late in the week as gold and silver rallied; Reuters noted the sector hit record levels intraday before trimming gains. If the dollar stays soft and bond yields remain pressured by rate-cut expectations, miners can remain a key swing factor for the FTSE 100. [34]
Consumer and retail: warnings meet hard data
Between Barclays’ softer consumer spending signals earlier in the week and Card Factory’s profit warning on Friday, the market has been repeatedly reminded that household demand remains fragile. That makes the late-week UK retail sales release especially important for retail-facing names and broader UK mid-cap sentiment. [35]
Defence and energy: headline-driven upside, but sensitive to geopolitics
Defence names drew support on expectations of large German contract approvals. Energy names also saw company-specific action (for example, Harbour Energy’s acquisition announcement). These sectors may remain reactive to geopolitical and commodity headlines even if UK macro dominates the diary. [36]
Three scenarios for the UK stock market week ahead
- Base case: BoE cuts 25bp; guidance stays cautious
If the BoE cuts and communicates a careful, data-driven path, the market reaction may be more muted—supportive for rate-sensitive pockets (select banks/financials, UK cyclicals), but unlikely to overwhelm global risk sentiment. [37] - More dovish: BoE cuts and hints at a smoother easing path
If communication leans decisively toward further cuts (or downplays upside inflation risks), gilts could rally and sterling could soften, which often boosts internationally weighted FTSE 100 earners while lifting domestic risk appetite—especially if UK CPI also cooperates. [38] - Hawkish surprise: cut (or even hold) but with “higher-for-longer” signalling
A more hawkish message—emphasising sticky inflation expectations or pushing back on the pace of further cuts—could hit rate-sensitive UK segments and potentially strengthen sterling. With markets already primed for easing, the asymmetry risk is that a “less dovish than hoped” signal causes outsized moves.
Bottom line for investors watching the FTSE 100 and FTSE 250
Going into 15–19 December, the UK stock market is balancing two narratives:
- A macro narrative that increasingly points toward easing monetary policy as growth cools and inflation drifts lower.
- A sentiment narrative shaped by global risk appetite, where “AI capex” anxiety can still trigger sharp moves that spill across regions—even when local fundamentals are in focus.
If you’re tracking the “week ahead” in London, the checklist is straightforward: UK jobs (16 Dec), UK CPI (17 Dec), BoE (18 Dec), and retail sales (19 Dec)—with WH Smith’s delayed results and Currys’ update as the key UK stock-specific catalysts in a lighter-than-usual corporate week.
