Brent Crude Tops $90 as US-Iran Negotiation Window Expires
Brent crude moved above $90 a barrel as a US-Iran negotiation window expired without an agreement and geopolitical tensions intensified.
In short
- Brent crude moved above $90 a barrel as a US-Iran negotiation window expired without an agreement and geopolitical tensions intensified.
Brent crude rose above $90 a barrel on August 18, 2026, its first move beyond that level since July 30, as a two-month window for negotiations connected to the US-Israel war on Iran expired without an agreement.
The renewed increase reflected concern that unresolved conflict and sharper rhetoric could threaten energy supplies. Iran said it would adopt a more aggressive stance if talks with the United States failed, while US President Donald Trump called on Tehran to surrender and threatened Oman, according to the source report.
Higher crude prices can feed into fuel and transport costs well beyond the immediate region. The move remains sensitive to diplomatic and military developments, and prices may change quickly as markets assess the risk to production and shipping.
