# War against Iran: Direct impact on oil and markets
The military escalation involving Iran rekindles tensions in the Middle East, a key region for global energy supply. Any threat to infrastructure or the Strait of Hormuz immediately triggers a reaction from the markets. About 20% of the world's oil passes through this strategic route. Result: investors are incorporating a risk premium, driving up crude prices.
A sustained rise in oil can fuel global inflation, increase transportation costs, and slow economic growth. Stock markets become more volatile, while some capital flows into commodities or alternative assets like Bitcoin.
For traders, the current geopolitical situation represents a major catalyst for volatility. Tracking the evolution of Brent, the dollar, and diplomatic announcements will be essential in the coming weeks.
