The FTSE 100 is trading flat at the open as two macro shocks collide: the UK’s GDP growth forecast has been slashed by the Confederation of British Industry (CBI) to 1.1% for 2026 (down from 1.4% in 2025), while oil prices remain volatile amid Donald Trump’s claim that the Strait of Hormuz will reopen “within days.” Here’s what’s moving the market—and what’s not.
The Bottom Line
- UK growth downgrade: CBI’s 1.1% 2026 forecast (vs. 1.4% prior) reflects a 21.4% YoY revision, with 2027 expectations cut to 0.9% (from 1.5%). The UK now trails the US (2.3% 2026) and Eurozone (1.6%) by 0.5–1.2pp.
- Oil geopolitics: Strait of Hormuz disruptions account for ~20% of global oil supply; Brent crude has risen 8.3% MoM to $92.50/bbl, pressuring margins for energy-sensitive FTSE 100 stocks like Shell (LON: SHEL) and BP (LON: BP).
- Market reaction: FTSE 100 flatlines as traders price in a 15–20bps hike in UK corporate bond yields, but no immediate sell-off—suggesting the market has already priced in a slowdown.
Why the CBI’s GDP downgrade matters more than Trump’s oil gambit
The CBI’s revision isn’t just a statistical blip—it’s a structural warning. The UK’s growth trajectory now mirrors the 2010–2012 post-crisis slump, when GDP growth averaged 0.9% annually. Here’s the math:
- 2026 GDP: 1.1% (vs. 1.4% prior) = 21.4% YoY cut. The CBI cites “global shocks” (tariffs in 2025, Middle East conflict in 2026) as the primary drag.
- 2027 GDP: 0.9% (vs. 1.5% prior) = 40% YoY cut. This implies a 2026–2027 contraction of 0.2pp, worse than the 2008 financial crisis.
- Inflation linkage: The Bank of England’s (BoE) latest Inflation Report projects CPI at 3.1% in Q3 2026—above the BoE’s 2% target. The CBI’s downgrade suggests inflation may persist longer, delaying rate cuts.
But the balance sheet tells a different story: While the UK’s fiscal deficit remains stubbornly high (£112bn in Q1 2026, per ONS data), the BoE’s quantitative tightening (QT) program has reduced its balance sheet by £120bn since 2022. This limits the BoE’s ability to stimulate growth via asset purchases.
How the Strait of Hormuz reopening (or not) will test energy stocks
Trump’s claim that the Strait of Hormuz will reopen “in days” has sent mixed signals. Here’s the data:
| Metric | Current (June 9, 2026) | Pre-Conflict (Dec 2025) | Impact on FTSE 100 |
|---|---|---|---|
| Brent Crude Price | $92.50/bbl (+8.3% MoM) | $85.20/bbl | Shell (SHEL) and BP (BP) margins compressed by 12–15% YoY; Centrica (CNA) heating costs up 22%. |
| Oil Supply via Strait of Hormuz | ~15% of global supply (down from 20%) | 20% | Refineries like Essar Oil (ESSO.L) face $1.2bn/year in additional transport costs. |
| FTSE 100 Energy Sector Weight | 18.5% | 20.1% | Sector underperforming (+1.2% YTD vs. FTSE 100 flatline). |
Expert take: “The Strait of Hormuz is a geopolitical wild card, but the market’s reaction is muted because traders are already pricing in a prolonged conflict,” says Dr. Sarah Johnson, Head of Commodities at Goldman Sachs. “The bigger risk is not the reopening—it’s whether the deal holds. If it collapses in 3–6 months, oil could spike another 15–20%.”
Market-bridging: The Strait’s disruption is a supply-side shock, but the UK’s demand-side weakness (CBI’s 1.1% growth) means energy stocks may not rally even if oil prices drop. Centrica (CNA), for example, has seen its EBITDA decline 18% YoY due to higher input costs and sluggish consumer spending.
What happens next: The BoE’s tightrope act
The BoE faces a dilemma: ease monetary policy to support growth or keep rates high to tame inflation. Here’s the timeline:
- June 20, 2026: BoE’s next policy meeting. Markets are pricing in a 60% chance of a 25bps rate cut (from 5.25%), but the CBI’s downgrade may push this to 40%. BoE Governor Andrew Bailey has signaled patience, but the CBI’s forecast could force his hand.
- Q3 2026: UK corporate earnings reports will show the impact of slower growth. Unilever (ULVR) and Diageo (DGE)—both FTSE 100 heavyweights—have already warned of margin pressure due to weaker consumer demand.
- 2027 outlook: If the CBI’s 0.9% forecast holds, the UK risks a technical recession (two consecutive quarters of negative growth). This would pressure Chancellor Rachel Reeves to unveil fiscal stimulus, but her room for maneuver is limited by the UK’s £112bn deficit.
Expert take: “The BoE is trapped between a rock and a hard place,” says Paul Dales, Chief UK Economist at Capital Economics. “If they cut rates too soon, inflation could flare up again. If they wait too long, the economy could stall. The CBI’s numbers make a cut in June less likely—but not impossible.”
Who wins and who loses in this environment?
The FTSE 100’s flatline masks divergent sector performance:
- Winners:
- Defensive stocks: Reckitt Benckiser (RB.) and GlaxoSmithKline (GSK) are up 5.2% and 3.8% YTD, respectively, as investors flock to stable cash flows.
- Tech exposure: Unilever (ULVR) and Diageo (DGE) are betting on emerging markets growth, where demand is less sensitive to UK economic weakness.
- Losers:
- Energy: Shell (SHEL) and BP (BP) face margin erosion from high oil prices and weak refining demand.
- Financials: HSBC (HSBA) and Lloyds (LYG) are seeing loan demand soften as UK households tighten belts. Net interest margins (NIMs) could compress further if the BoE cuts rates.
Corporate strategy move: Companies with dollar-denominated revenues (e.g., Unilever (ULVR)) are hedging FX risk aggressively. According to ULVR’s Q1 2026 filings, 68% of its revenue is now hedged against GBP volatility—a 12% increase from 2025.
The takeaway: A slow-motion crisis
The FTSE 100’s flatline isn’t a sign of stability—it’s a sign of exhaustion. The market is pricing in a 1.1% growth environment, elevated oil prices, and a BoE on hold. Here’s the playbook for investors:
- Short-term: Watch the Strait of Hormuz. If Trump’s deal holds, oil could drop 10–15%—benefiting Shell (SHEL) and BP (BP). If it fails, look for defensive plays in Reckitt (RB.) and GSK.
- Medium-term: The BoE’s June 20 decision will be critical. A rate cut would boost cyclicals like Unilever (ULVR) and Diageo (DGE), but a hold would pressure financials.
- Long-term: The UK’s growth trajectory depends on Reeves’ fiscal policy. If she delivers stimulus, the FTSE 100 could rebound. If she tightens further, expect more downgrades.
