London Stock Market: What to Know Before the FTSE 100 Opens on Monday, 17 November 2025

After a volatile Friday driven by UK budget headlines and surging gilt yields, London investors head into a pivotal week featuring Japan’s GDP before the bell, UK CPI on Wednesday and UK retail sales on Friday.

Key takeaways at a glance

Friday’s jolt: UK stocks, gilts and sterling fell on Nov. 14 after reports that the government would not raise income tax in the Nov. 26 budget, stoking fiscal worries. The FTSE 100 dropped 1.1% on the day even as the week eked out a gain. Ten‑year gilt yields jumped to ~4.58% and the euro touched its strongest level against the pound since 2023. ^[1]
Record highs now in the rear‑view: Earlier in the week, the FTSE 100 set new records as soft UK labour data fed hopes of near‑term rate cuts. That optimism has since been tempered by the budget noise. ^[2]
Macro before the open: Japan’s preliminary Q3 GDP lands 08:50 JST Monday (23:50 GMT Sunday)—before Europe wakes—after a Reuters poll flagged likely contraction. The print could sway global risk tone into London’s opening auction. ^[3]
The UK data week: October CPI arrives Wednesday, 19 Nov at 07:00 UK time; retail sales follow on Friday, 21 Nov at 07:00. Both are key checks on Bank of England (BoE) cut expectations into year‑end. ^[4]
Corporate diary, Monday:Ninety One (asset management) interim results, Sirius Real Estate H1 results, and Big Yellow Group H1 after the close. ^[5]
Oil & FX backdrop: Brent steadied around the low‑$60s late last week after a sharp slide, while sterling weakened on Friday as gilt yields spiked—two inputs to watch for energy and exporter shares at the open. ^[6]

The market set‑up: London opens after a fiscal‑messaging shock

British assets were whipsawed on Friday, Nov. 14, as reports that Chancellor Rachel Reeves ditched plans to raise income tax in the Nov. 26 budget rippled through markets. Stocks fell, gilt yields jumped and the pound weakened, reflecting concern that fiscal consolidation may be harder to achieve without headline tax increases. The FTSE 100 fell 1.1%—its sharpest one‑day drop since April—though it still posted a modest weekly gain. ^[7]

The pressure built alongside a broader global wobble: fading hopes of near‑term Fed rate cuts pushed bond yields higher and left Wall Street mixed into the weekend, setting a cautious tone for Monday’s Europe open. ^[8]

That contrasts with mid‑week euphoria when the FTSE 100 notched fresh records after UK labour data showed unemployment at 5% and slowing wage growth—fuel for rate‑cut bets. ^[9]

What could move the FTSE 100 before the bell

1) Japan’s GDP hits screens just before Europe wakes

Japan’s preliminary Q3 GDP is scheduled 08:50 JST Monday (23:50 GMT Sunday). Economists surveyed by Reuters had expected the first contraction in six quarters, largely on weaker exports. A downside surprise could dampen global risk appetite; an upside surprise could help lift cyclicals into London’s open. ^[10]

2) Oil price stabilisation watch

Brent crude steadied near $63 on Thursday after a ~4% downdraft the prior session amid oversupply worries. Energy heavyweights on the FTSE 100 are sensitive here; further weakness can weigh on the index, while stability could curb recent underperformance in energy names. ^[11]

3) Sterling and gilts after Friday’s spike

The pound fell and the 10‑year gilt yield leapt to ~4.58% on Friday as budget expectations reset. A stronger pound typically drags on FTSE multinationals’ translated earnings; higher gilt yields pressure domestic rate‑sensitives from real estate to housebuilders. Watch whether either move reverses in early trading. ^[12]

The UK policy & data pipeline investors will price in

BoE stance: On 5 Nov, the Monetary Policy Committee held Bank Rate at 4% (5–4 vote; four members sought a 25 bps cut). That close split keeps December/early‑2026 easing in play—especially if inflation and activity soften. ^[13]
Inflation next:October CPI is due Wed, 19 Nov, 07:00. Markets had boosted bets on a December cut after inflation held at 3.8% in September; Wednesday’s print will test that dovish narrative. ^[14]
Consumption check:Retail sales (October) arrive Fri, 21 Nov, 07:00, with ONS release timing confirmed. Retailers have flagged cautious consumers ahead of Black Friday and the budget—another swing factor for mid‑caps. ^[15]
Budget countdown: The UK budget lands 26 Nov, a marquee event for gilts, sterling and domestics. Last week’s communications drew criticism from business groups and unsettled investors; expect pre‑budget positioning to remain a driver. ^[16]

Companies to watch on Monday, 17 Nov

Ninety One (N91) — Interim results (H1 FY26). The manager flagged £152.1bn AUM at Sept. 30 and scheduled results for Nov. 17. Focus: net flows, performance fees and any read‑through on client risk appetite after the AI‑led tech volatility. ^[17]
Sirius Real Estate (SRE) — H1 results. The industrial/workspace landlord pre‑trailed stronger rent roll and ample liquidity; details on German/UK occupancy and yields will be in view. ^[18]
Big Yellow Group (BYG) — H1 results after the close. Management flagged a post‑market release today with an analyst call tomorrow morning; investors will parse pricing power and development pipeline against higher funding costs. ^[19]

Also useful: Alliance News’ forward diary flagged the same Monday line‑up—Big Yellow, Ninety One and Sirius Real Estate—underscoring the day’s real‑assets/asset‑management tilt. ^[20]

Sector lens for the open

Banks & insurers: Friday’s jump in gilt yields hurt financials and could stay in play if budget jitters persist. Banks sold off on fears of sector‑specific tax grabs if income‑tax rises are off the table. Insurers also weakened. ^[21]
Energy: With Brent stabilising in the low‑$60s after recent losses, majors may see some respite if crude holds. Keep an eye on any fresh supply headlines. ^[22]
Miners: China growth worries and recent Asian equity outflows have pressured cyclicals; sentiment from Asia trade overnight (including the Japan GDP print) may set the tone. ^[23]
Rate‑sensitives (housebuilders, REITs): Higher gilt yields and shifting BoE expectations tend to weigh here; Wednesday’s CPI will be pivotal. ^[24]
Export‑heavy multinationals: A weaker pound can support earnings translation; if sterling rebounds, that tailwind fades. ^[25]

US and global cues into Monday

Wall Street ended mixed on Friday as hopes for a December Fed cut cooled; the Nasdaq eked out a gain, while the Dow slipped, leaving global risk sentiment delicate heading into Asia’s Monday session and Europe’s open. Nvidia’s results later this week remain a key global catalyst for tech and AI‑linked sentiment. ^[26]

Practical: London opening mechanics (and why 07:50 matters)

Opening auction: The LSE’s main order book (SETS) runs an opening call 07:50–08:00, when buy/sell interest crosses to set official opening prices. Regular trading runs 08:00–16:30, followed by the closing auction 16:30–16:35. Understanding imbalances in that opening call can help explain early gaps and index moves. ^[27]

The week’s UK narrative in one line

From record highs to risk reset: London enters Monday balancing softer domestic data (which had boosted cut hopes) against fiscal uncertainty and global yield pressures—making Wednesday’s CPI and Friday’s retail sales the decisive markers for whether the BoE can start easing as soon as next month. ^[28]
