UK equities already pricing in worst of post-ceasefire slowdown, GS says

Goldman Sachs says the US-Iran conflict has pushed UK equities to near-recessionary valuations, with FTSE 250 multiples now consistent with zero or slightly negative activity and UK Q4/Q4 GDP growth cut to 0.6% from 1.5%. The brokerage expects Strait of Hormuz energy flows to recover over the weekend and Persian Gulf exports to normalize over one month, while trimming Q2 Brent to $90 and forecasting the UK 10-year gilt yield to fall from 4.8% to 4.4% over 12 months. FTSE 100 ended at 10,603 and Goldman’s 12-month target is 10,800, with higher inflation and defensive positioning still a key theme.

Analysis

The key market inefficiency is that the immediate winners and losers are not the obvious energy names, but the duration-sensitive domestic UK assets already pricing a recessionary shock without yet seeing the second-round inflation impulse. If energy stays elevated for even 4-8 weeks, the hit to real incomes and retail volumes arrives before the growth downgrade fully works through earnings, which means the lagging losers are UK discretionary, homebuilders, and rate-sensitive small caps rather than broad defensives. Conversely, the FTSE 100 is unusually insulated because its sector mix skews to defensives and energy; that creates a relative-value bid even if UK macro deteriorates further.

The more interesting second-order trade is in rates. If markets have already marked down growth but not fully priced a persistence of inflation via energy pass-through, gilts can initially sell off on inflation data even while the medium-term growth path weakens. That sets up a two-stage path: near-term volatility higher in the front end, but 10-year yields likely grind lower as hard data confirm weaker domestic demand and mortgage/rent transmission cools inflation after the initial shock. The cleanest catalyst for the bull case in gilts is not a geopolitical de-escalation alone, but evidence that services inflation and retail volumes are rolling over together.

The contrarian view is that the discount in UK cyclicals may be close to a value trap if the conflict normalizes quickly and energy retraces, because the domestic earnings revisions lag the equity reset by a quarter or more. That means the best relative expression is not outright long UK domestics, but hedged exposure versus exporters or defensives. In short, the market is likely underpricing the near-term inflation shock and overpricing the permanence of the growth shock.

Key Decisions for Investors

• Long IGLT or TLT-like duration exposure via 10Y gilt futures; 3-6 month horizon. Buy on any near-term inflation-driven yield spike toward 5.0% with a 4.4% 12-month target in mind; risk is a renewed oil spike that delays the decline.
• Short UK domestic cyclicals via a basket of FTSE 250 retailers/homebuilders or use IUKD/UK small-cap proxies against long FTSE 100 exposure; 1-3 month horizon. The pair should benefit if energy pass-through hits real incomes before growth stabilizes.
• Long FTSE 100 futures / short FTSE 250 futures as a relative-value expression; 1-2 month horizon. This captures defensive/commodity index composition while avoiding the domestic-demand trap; risk is a rapid de-escalation that lifts UK cyclicals more than the large-cap index.
• Buy Brent upside protection through call spreads rather than outright length; 1-2 month horizon. The asymmetry is still to the upside if shipping disruption reappears, but call spreads limit theta bleed if supply normalizes faster than expected.
• For equity defensives, prefer UK staples/healthcare over UK banks and consumer discretionary; 3-6 month horizon. The market is likely to keep treating domestic earnings as if the recession case is permanent, creating relative outperformance in cash-generative defensives.
