Oil prices rose for a fifth straight day on Thursday, reaching their highest levels in more than a month after Yemen’s Houthis said they struck two Saudi oil tankers, adding to concerns about disruptions to global supply routes beyond the Strait of Hormuz.
Brent crude futures were up $4.52, or 4.8%, at $98.59 a barrel by 0935 GMT after reaching their highest level since June 3. U.S. West Texas Intermediate crude rose $3.39, or 3.9%, to $90.22 after touching its highest since June 11.
The Iranian-aligned Houthis said they struck two Saudi oil tankers as part of what they described as a naval blockade of Saudi Arabia in the Bab el-Mandeb strait.
Shipping data showed two Chinese supertankers carrying a combined 4 million barrels of Saudi oil were exiting the Red Sea through Bab el-Mandeb on Thursday, even as a Saudi vessel came under attack in the region.
Iran’s Revolutionary Guards said an oil tanker caught fire after an explosion while attempting to follow a mined route in the southern Strait of Hormuz near Oman’s coast, and that two other tankers had turned back.
The Guards said the strait was under their control and “completely closed” while U.S. actions continued in the region, and warned that no tanker would be allowed to enter or leave without coordination with Iran.
