Global crude oil prices climbed on Friday as growing tensions between the United States and Iran increased concerns about potential disruptions to energy supplies from the Gulf region.

Brent crude, the international benchmark, rose by 70 cents to reach $85.28 per barrel, while US West Texas Intermediate (WTI) crude gained 81 cents to trade at $80 per barrel. UAE Murban crude was trading at $77.73 per barrel.

The latest gains cap a strong week for oil markets, with both major benchmarks recording increases of nearly 12 percent. Brent crude is on track for its third consecutive week of gains, while WTI is expected to end a second straight week in positive territory.

Market analysts say geopolitical risks remain the main driver behind the rally. Tim Waterer, Chief Market Analyst at KCM Trade, said concerns over potential disruptions in the Red Sea and Gulf shipping routes have added a risk premium to oil prices.

The surge follows renewed military activity between Washington and Tehran. Reports indicate that US forces carried out major airstrikes against Iranian targets this week, while Iran responded with missile and drone attacks targeting American military facilities in the region.

Regional tensions have also raised concerns about the security of key oil transport routes. According to reports, Iran has instructed allied Houthi forces to be prepared to disrupt shipping in the Red Sea if Iranian energy infrastructure comes under attack.

Meanwhile, International Energy Agency Executive Director Fatih Birol warned that energy security has become a major concern and said market uncertainty could intensify if the situation fails to improve in the coming weeks.

Analysts believe oil prices could rise further if tensions escalate, increasing pressure on fuel-importing countries and global inflation.
