No 10 ‘must reveal Boris Johnson’s secret deal on Chinese embassy’

Residents adjacent to Royal Mint Court have warned they will begin legal proceedings in early February seeking disclosure of a 2018 'note verbale' in which Boris Johnson, then foreign secretary, reportedly granted 'conditional diplomatic consent' for a proposed Chinese 'super-embassy' in central London. The government formally approved the plans last week; campaigners and lawyers say releasing the note is central to their challenge, a dispute that may complicate Prime Minister Keir Starmer’s imminent China trip and add political and diplomatic uncertainty to UK–China investment conversations.

Analysis

Market structure: The immediate winners are activist groups and lawyers (driving legal services demand) and political short-term volatility trades; losers are central-London landlords, developers with China-linked funding and any incumbents owning Royal Mint Court adjacent assets. Expect localized pricing pressure: submarket rents/sales within a 500–1,000m radius could reprice down 5–15% if an injunction halts development for >6 months, while broader UK property indices likely see <2% direct impact absent wider diplomatic escalation.

Risk assessment: Tail risks include a full diplomatic rupture with China (low-probability but high-impact) that could pause Chinese FDI into UK real estate and infrastructure for 6–24 months, pressuring bank exposures and property-backed credit. Time horizons: immediate (days) for volatility spikes around Feb 1 legal filing, short-term (weeks–3 months) for option/FX moves tied to the PM's China trip, long-term (quarters–2 years) for shifts in foreign capital flows into UK real estate.

Trade implications: Tactical protection of UK property beta and GBP is warranted. Hedging via targeted put spreads on UK-listed real estate names and 1–3 month GBP put options is cost-effective; selective long exposure to UK banks with deep China franchises (HSBC: HSBA.L) is a conditional rebound trade if the trip yields investment headlines.

Contrarian angles: Consensus treats this as a political skirmish; market may underprice the concentrated liquidity effect in central-London office/residential submarkets and overprice systemic risk. If the note is published within 30 days and litigation fails, expect a 3–7% mean reversion rally in affected REITs; conversely, prolonged legal uncertainty is an idiosyncratic buying opportunity in high-quality landlords trading >10% off NAV.

Key Decisions for Investors

• Establish 1–2% portfolio hedges via 3-month put spreads on Derwent London (DLN.L) and Landsec (LAND.L): buy 3-month 10% OTM puts and sell 5% OTM puts to limit cost; increase notional x2 if a legal injunction is filed by Feb 1.
• Buy 1–1.5% notional of 3-month GBP put options ~3–4% OTM (or a short GBPUSD forward) to protect versus a diplomatic headline shock around the UK-China trip; close or trim if GBP recovers >2% on positive investment headlines within 30 days.
• Initiate a conditional 1% long in HSBC Holdings (HSBA.L) vs 1% cash: if the Prime Minister returns with signed MOUs or announced Chinese investment within 60 days, add another 1–2%; exit if sanctions/escalation language appears in official communiqués.
• If affected central-London REITs widen >10% relative to FTSE 350 on legal uncertainty beyond Q2 2026, allocate contrarian 1–2% buys into high-quality names trading >10% below NAV (target 8–12% IRR over 12–24 months) and scale in on resolution milestones (legal ruling, published note verbale).
