Brent crude oil prices have risen above $90 per barrel as renewed clashes between the United States and Iran fuel concern about potential Middle East supply disruptions. Brent had traded around $90 for much of August after a period of relative stability. Prediction-market pricing shows a marginally higher probability of crude reaching a new all-time high, with a 3.1% YES probability for September 30 and 12.5% for December 31. Market participants are watching U.S.-Iran relations, production decisions by OPEC (Organization of the Petroleum Exporting Countries) members and Saudi Arabia, and analysis from the International Energy Agency for indications of how the conflict could affect oil prices.
