Prime Minister Sir Keir Starmer defended a restrained UK response to the US-Israel strikes on Iran, prioritising protection of British nationals and declining to join initial offensive action without a lawful basis and a viable plan, while later permitting US defensive use of British bases. The government is pre-deploying radar, ground-based air defences, F-35s, Wildcat anti-drone helicopters and dispatching HMS Dragon amid missile and drone strikes on regional bases, and political opponents and US officials have criticised the decision. The developments raise regional escalation risk and could influence defence positioning and risk sentiment among investors, though the UK has sought to limit direct engagement for now.
Market structure: Near-term winners are defence primes and niche security suppliers (air-defence, counter-drone) and energy producers exposed to Gulf supply risk; losers are Gulf-exposed airlines, regional hospitality and shipping/containers on reroutes. Expect 5–15% short-term spread widening in insurance/shipping rates and a 3–7% upside shock to Brent if attacks escalate or Strait of Hormuz disruptions occur within days. Currency flows favor USD and gold as safe havens; UK political uncertainty can pressure GBP by ~2–4% in a material escalation.
Risk assessment: Tail risk includes broader regional war (probability low-moderate ~5–12%) driving Brent > $100/bbl and global growth shock; cyber or asymmetric attacks on oil infrastructure could create rapid 10–20% commodity moves. Immediate (days) risk = volatility spikes across energy, gold, and defence equities; short-term (weeks–months) risk = rerouted shipping costs and insurance; long-term (quarters+) = potential uplift in UK and European defence budgets if conflict persists. Hidden dependencies include US political dynamics and UK domestic politics shaping procurement timing and stock reactions; catalysts are further strikes on bases, OPEC+ supply responses, and declared UK offensive involvement.
Trade implications: Tactical long exposure to defense names (BAE.L, LMT, RTX) and selective energy producers (XOM, CVX, XLE) for 1–3 month horizons; buy short-dated Brent call spreads that pay if Brent > $90 within 6–12 weeks. Short Gulf-exposed airlines (IAG.L, EZJ.L) and buy puts on cruise/airline ETFs for 2–8 week windows as fuel/route disruption manifests. Use options to size convexity: small dollar long-call positions on LMT/BAE and protective puts on UK equities if GBPUSD breaches 1.22.

Contrarian angles: Consensus prices a sustained defence premium; if conflict remains localized, energy and insurance spikes will mean-revert in 4–8 weeks—opportunity to fade volatility. Defence order flow and margins are sticky (multi-quarter) but stocks often move faster than fundamentals; consider staggered entries and selling short-term volatility after 20–40% run-ups. Historical parallels (limited 2019–2020 Gulf skirmishes) show oil spikes then retracement; set objective sell triggers (e.g., trim energy longs if Brent rallies >20% from baseline).
