Iran curbs impossible to meet

LONDON: Europe's oil embargo on Iran is having unforeseen consequences in the shipping market, making it almost impossible to determine if vessels are using fuel that violates the sanctions.

Supplies from Iran are a "vital blending component" to make ship fuel, known as bunkers, according to Barclays Capital.

The nation accounted for about 8% of bunkers exported last year to Asia, the largest market, and about a third of the supply at Fujairah in the UAE, the Middle East's biggest refueling port, Barclays estimates.

The European Union imposed curbs on Iranian oil because of concern the country's nuclear programme will produce an atomic weapon.
