Summary
War in Iran is triggering massive turbulence in global financial markets. The Swiss Swiss Market Index (SMI) fell by nearly 3 percent by Tuesday noon, while oil and gas prices rose significantly. Iran's blockade of the Strait of Hormuz is considerably exacerbating energy supply risks. Experts warn of further price declines if the conflict persists longer and expect possible oil prices exceeding $100 per barrel.

Clarus Lead
The Iran conflict is massively destabilizing global capital markets. The Swiss leading index lost nearly 3 percent on March 3, 2026, while European and American exchanges also came under pressure. Iran's blockade of the strategically important Strait of Hormuz threatens global oil supply and drives commodity prices higher – a critical risk for corporate earnings and inflation trends.
Detailed Summary
On the fourth day of the Iran war, the economic consequences are evident as dramatic. The SMI slumped by nearly 3 percent by Tuesday noon, after already starting trading down 1.5 percent. In parallel, Germany's DAX lost 1.8 percent and slid to its lowest level since December 2025. The EuroStoxx 50 declined 1.6 percent. Wall Street and Nasdaq are also projected to close with falling prices, underscoring the global contagion effect.
Energy price spikes are particularly alarming. Brent North Sea crude oil rose 3.8 percent to $80.66 per barrel, WTI oil gained 3.5 percent to $73.76. Gas prices exploded by over 30 percent and reached almost 55 Swiss francs per megawatt-hour – the highest level since February 2023. Financial experts from NordLB national bank warn: If the conflict persists longer and expands regionally, oil prices exceeding $100 per barrel should be expected. Iran's closure of the Strait of Hormuz is the catalyst here – this waterway is the central oil and gas route for global trade. Economic and inflation concerns have thereby noticeably intensified; further developments depend critically on the conflict's duration.

Critical Questions
Data Quality: Are the price figures (SMI -3%, DAX -1.8%) based on intraday data from March 3 at 12:20 p.m.? How are short-term fluctuations distinguished from longer-term trends?
Conflicts of Interest: Which financial institutions have vested interests in oil price increases or market volatility and are cited in the reporting?
Causality: Is the Strait of Hormuz blockade already fully in effect, or is it an announcement? How large is the isolated effect of this blockade versus generalized war risk premiums?
Feasibility/Risks: What specific tools do central banks or governments have available to absorb energy price shocks? How likely is military escalation beyond current boundaries?
Alternative Scenarios: Could a swift diplomatic solution stabilize prices, or have structural upheavals already been set in motion?
Expert Statement Validation: On what data basis do NordLB experts assess the $100 scenarios? Are there opposing positions in the analyst community?
