US, Iran Tanker Attacks Escalate; Oil Prices Surge

**Implied Volatility / Movement:** Increased volatility expected due to geopolitical tensions.

## Catalyst Analysis: Escalated Tanker War The U.S. and Iran have engaged in a tit-for-tat escalation of attacks on oil tankers, with Washington targeting three Iranian vessels and Tehran retaliating against tankers and U.S. warships near the Strait of Hormuz. These exchanges, which occurred around September 5, 2026, have intensified the months-long conflict, aiming to control the strategic waterway.

## Impact on Energy Markets ### Winners, Losers & Uncertainty The primary impact observed is a surge in energy prices. Brent crude futures closed on Friday at $96.28 a barrel, a significant rise from approximately $70 before the conflict. U.S. gasoline prices reached a record average of $5.85 per gallon ($1.55 per litre) on Friday. The disruption to energy supplies and potential impact on global economic growth remain key concerns.

### Risk Watch The conflict highlights geopolitical risks in the Strait of Hormuz, a critical chokepoint for global oil trade. The U.S. Central Command (CENTCOM) stated its actions were a response to Iranian ballistic missile launches. Iran's IRGC claimed responsibility for missile launches targeting U.S. warships and stated its forces targeted oil tankers. The situation introduces uncertainty regarding future de-escalation through diplomacy and its effect on energy markets.
