The attacks have already stoked concerns about reduced flows of crude oil on one of the world's key shipping routes, pushing up oil prices by as much as 4.5%.
Freight rates for supertankers transporting oil from the Persian Gulf to Asia were already close to a two-month high on Thursday at nearly $13,000 a day, up nearly $2,000 from Wednesday, Reuters reported.
Every ship needs various forms of insurance, including annual war-risk cover as well as an additional 'breach' premium when entering high-risk areas. These separate premiums are calculated according to the value of the ship, or hull, for a seven-day period.
On Thursday morning, two oil tankers – one sailing under a Panama flag and owned by Japan and another bearing the Marshall Islands’ ensign owned by Norwegian Frontline – were hit by yet unspecified accidents in the Sea of Oman. Iranian rescuers rushed to the assistance, transferring all of their 44 crew members to Iran's southern shores.
