Brent crude rose above $88 a barrel on Friday, gaining more than 5% this week as the US increased economic pressure on Iran to reopen the Strait of Hormuz. Treasury Secretary Scott Bessent said Washington would impose unprecedented economic measures while maintaining its naval blockade of Iranian ports, with further announcements expected next week. The International Energy Agency also warned of a deeper global supply deficit, forecasting the widest shortfall in 2026 in five years. Meanwhile, Iran and Oman have yet to reach an agreement on reopening Hormuz, despite earlier optimism that a deal was close. US officials said American forces are increasing their ability to escort vessels through the strait, although shipping remains risky, with some tankers switching off transponders. In the Red Sea, Iran-backed Houthi militants also targeted Saudi Arabia’s Jazan refinery. Meanwhile, additional Middle Eastern crude is expected to reach the US, offering some relief to low inventories.
