Brent crude oil prices surged to a six-month high on Friday as escalating tensions in the Middle East, attacks on Saudi Arabia’s energy infrastructure and fears of renewed US military action against Iran heightened concerns over global oil supplies.
Real-time market data showed Brent crude futures for December 2026 delivery trading at $116.29 a barrel, up $3.12, or 2.76%, at 20:38:07. The international benchmark touched its highest level since late April, extending its rally as investors priced in the possibility of further supply disruptions across the region.
US West Texas Intermediate (WTI) crude futures also advanced, trading around $102.56 a barrel, up nearly 3%, according to CNBC. Brent was on track for its third consecutive weekly gain, with the contract heading towards a weekly rise of nearly 6%, CNBC reported.
