LONDON, Sept 11 (Reuters) – The cost of shipping oil in the largest tankers hit record highs this week following the biggest wave of attacks on ​shipping since the U.S.-Iran war began in late ‌February.

The shipping rate for supertankers – also called very large crude carriers or VLCCs – loading oil from the Gulf of Oman for shipment to China reached around 450 on a Worldscale basis, equaling roughly $11.50 per barrel, ‌according ​to Baltic Exchange data. This is the ⁠highest since the rate ⁠was launched earlier this year, after the start of the U.S.-Israeli war with Iran.

The spike in rates shows how the Middle East conflict is feeding into the broader economy. ​If elevated shipping costs persist, they could add to inflationary pressures and further raise costs for businesses and consumers ⁠already facing uncertainty from the widening ⁠conflict.

Iran said on Wednesday it had attacked 10 ​ships near the Strait of Hormuz after the U.S. sank ​five Iranian oil tankers.

Yemen’s Iran-aligned Houthis on Friday reached ‌the strategic island of Perim in the Bab el-Mandeb Strait, four Yemeni government sources told Reuters, potentially tightening their grip on one of the world’s vital shipping routes.

“Renewed attacks between the ⁠U.S. Navy and Iran continue to push freight rates around the Gulf to new highs,” said Vortexa analyst Ioannis Papadimitriou.

The higher risk ⁠of operating in ‌and around the Middle East Gulf is ⁠also driving Gulf of Oman freight rates ​higher, in ‌fear of Iranian retaliation, which naturally thins ​the available ⁠tankers in the region, Papadimitrou added.

The recent military escalation in the region is also having a wider knock-on effect, as VLCC rates on the West Africa to Asia route also reached record highs.
