European Stocks Edge Higher as Investors Weigh US-Iran Tensions; WH Smith Plunges 16%

European stocks are holding their footing but only just. On June 10, 2026, the STOXX 600 opened at 621.72 and traded in a range of 621.10 to 625.22, as European shares edged up while investors parsed the fallout from US-Iran tensions with limited conviction across sectors. The FTSE 100 stood at 10,345, and the DAX traded at 24,790, while the CAC 40 held near 8,164.

Against this fragile backdrop, British travel retailer WH Smith (LON: SMWH) delivered one of the sharpest single-day falls on the FTSE 250, erasing months of value in a single session.

European Stock Benchmarks on June 10, 2026

The headline numbers tell a story of cautious resilience across European stocks. Key index levels as of June 10:

• STOXX 600 (SXXP): 621.72 open; 52-week range 532.34–636.16
• FTSE 100 (^FTSE): 10,345.43, down 0.27%
• DAX (^GDAXI): 24,790.49, up 0.71%
• CAC 40 (^FCHI): 8,164.00, down 0.55%
• Euro STOXX 50: 6,060.12, down 0.78%

Asian stocks plunged ahead of the European open following the largest exchange of fire between the US and Iran since April’s ceasefire. Japan’s Nikkei slipped 2%, while South Korea’s Kospi tumbled 6% after the United States carried out strikes in response to Iran’s downing of a US helicopter near the Strait of Hormuz. Europe absorbed the shock and steadied, but gains remain thin.

WH Smith: A Profit Warning That Shocked the Market

The WH Smith (LON: SMWH) was the headline loser on European stock exchanges on June 10. WH Smith now expects full-year 2026 headline pre-tax profit between £75 million and £90 million, a significant reduction from prior guidance, as Middle East flight disruptions and weaker consumer confidence hit passenger spending across its airport retail network.

The key numbers behind the sell-off:

• North America like-for-like sales: Down 4% over the past seven weeks
• Potential InMotion impairment charge: Up to £150 million
• Net debt (as at February 28, 2026): £496 million, up from £390 million at August 31, 2025
• Leverage ratio: 2.9x headline EBITDA, up from 2.1x
• Dividend: Suspended; final 2025 payout of 6 pence per share was the last

WH Smith also announced plans for a major equity raise to strengthen its balance sheet and support its ongoing turnaround programme.

The Iran Factor: Still Driving European Stock Sentiment

Geopolitics remain the dominant variable for European stocks in June 2026. Since hostilities began on February 28, 2026, the pan-European STOXX 600 declined 8% in March, its biggest monthly drop since 2022. Consumer discretionary, financial, and technology stocks led the declines, while only energy outperformed. 

Energy stocks including Shell (LON: SHEL) and TotalEnergies (EPA: TTE) have been consistent outperformers since February. Brent crude slipped 0.2% to $91.28 a barrel on June 10 despite the escalation, reflecting market uncertainty but no broad conflict-escalation pricing. European stocks outside energy remain caught between geopolitical risk and cautious macro data ahead of the US CPI release. 

Conclusion

European stocks are navigating a narrow path on June 10, 2026. The STOXX 600 near 622, the FTSE 100 at 10,345, and the DAX at 24,790 all reflect a market holding on, not breaking out.

WH Smith’s profit warning is the session’s starkest corporate signal: Iran-linked travel disruption and weak North American consumer spending are hitting real revenues now. Until the Strait of Hormuz fully reopens, European stocks will continue to grind higher with caution and zero margin for bad news.
