Global oil prices edged modestly lower in Wednesday afternoon trading, remaining nearly 10% higher than before Israel’s first attack on Iran last week, as investors look for evidence of supply disruption in crude markets as the conflict enters its sixth day.

The dramatic escalation in tensions between Israel and Iran caused a spike in the price of crude and raised fears among oil traders about disruption to shipping in the Strait of Hormuz, one of the world’s most vital waterways.

Critical energy infrastructure in Israel and Iran has not escaped unscathed from the first few days of the countries' escalated conflict. Worst-case scenarios have yet to be realized, but the war is already having a notable impact on energy production and exports in both countries.
