Increased tensions in the Persian Gulf could lead to disruptions in global oil supply chains impacting energy costs and market stability.

The Context
- Escalating tensions: U.S. and Israeli military actions against Iran began on February 28, 2026, disrupting shipping in the critical Strait of Hormuz.
- Failed negotiations: Peace talks in Islamabad on April 11 fell apart when Iran refused to negotiate its nuclear program, prompting U.S. military action.
- Market reactions: The announcement has already led to volatility in oil markets, with Brent crude prices rising.
The Number
