Swiss Market Ends Sharply Lower
Switzerland’s SMI fell sharply on Monday, closing at 13,305.40 (-1.75%, -237.26 points) as hopes for a U.S.-Iran peace deal faded. Iran’s Tasnim said Tehran would halt talks and close the Strait of Hormuz, citing U.S. ceasefire violations; U.S. Central Command said it carried out self-defense strikes on Iranian drone-related sites. Roche and Novartis dropped 3.61% and 3.33%. Swiss retail sales rose 1.6% y/y in April, while Q1 GDP grew 0.4% (revised down from 0.5%).

Risk-off pressure on Swiss large-cap pharma; likely correlates with SMI drawdown.
Novartis ended down 3.33% during the Swiss market selloff tied to U.S.-Iran ceasefire violations.
Limited single-name edge unless escalation worsens or pharma-specific flows emerge.
Background
The selloff is linked to renewed U.S.-Iran tensions: Tehran accuses the U.S. of violating a ceasefire; reports say talks may halt and the Strait of Hormuz could be closed.
Why it matters
The immediate tradable signal is broad equity risk reduction across Switzerland, with pharma and cyclicals notably down; macro data provides additional pressure via a downgraded growth outlook.
Market relevance
This is primarily a geopolitics-driven risk-off tape for Swiss equities, with macro prints reinforcing uncertainty.
Market effects
Geopolitical escalation (Strait of Hormuz closure risk) raises energy/uncertainty premium, pressuring broad Swiss equities; defensives still sold.
SMI closed down 1.75%, indicating Switzerland-wide de-risking tied to Middle East developments and softer growth outlook.
U.S.-Iran escalation risk can spill into European risk assets and energy/commodity expectations globally.
Alternative perspectives
Some Swiss names (e.g., Logitech, Kuehne+Nagel, UBS) outperformed, suggesting flows/hedging may be offsetting pure geopolitics beta.
The article also cites Swiss macro prints (retail sales beat; GDP revised down; growth outlook downgraded), which can compound or partially offset the geopolitical driver.
