New York: Iran will cut some benefits to Indian state-run refiners on crude purchases after the South Asian country decided to reduce the amount of oil it buys from the Arabian Gulf nation, people with knowledge of the matter said.

National Iranian Oil Co will cut the credit period on crude oil sales to 60 days from 90 days for refiners such as Mangalore Refinery & Petrochemicals Ltd and Indian Oil Corp, the people said, asking not be identified as the matter isn’t public yet. Iran will also reduce the discounts it offers on the shipping of crude to 60 per cent from 80 per cent, they added.

The lower incentives will make Iranian purchases costlier and less competitive in a world awash with crude oil where rivals such as Saudi Arabia and Iraq are seeking to expand their market share. Iran’s crude sales to India more than doubled in 2016 after the lifting of sanctions over its nuclear program. India is Iran’s second biggest customer and the emerging centre of global oil demand.

India in turn, is using the supply glut to put pressure on Tehran for securing development rights to the Farzad-B gasfield in the Arabian Gulf, which was discovered by an Indian consortium led by ONGC Videsh Ltd. about a decade ago. Iran and India were aiming to conclude an agreement on developing the field by February. The South Asian nation, which stood by Iran during the sanctions, is seeking to invest as much as $20 billion (Dh73.4 billion) in Iran’s energy industry and ports.

Cutting purchases

Indian state-run refiners told Iran last month that they would cut oil purchases by 3 million tonnes during the financial year that started April 1, the people said. MRPL and Indian Oil will reduce imports by 1 million tonnes each, while Hindustan Petroleum Corp and Bharat Petroleum Corp. will cut purchases by about half a million tonnes each, according to the people.

India’s overall oil imports from the Arabian Gulf nation touched 19.8 million tonnes during April-December last year, compared with 12.7 million tonnes in the 2015-16 financial year, according to oil ministry data.

Iran’s Oil Minister Bijan Namdar Zanganeh said “there are many other customers” if India decides to cut imports, the state-run Islamic republic News Agency reported on April 5. Reuters earlier reported Indian state refiners will cut oil imports from Iran by a fifth.

India’s Oil Minister Dharmendra Pradhan said April 6 that it’s up to the state refiners to decide on Iran crude volumes.

MRPL spokesman Prashanth Baliga couldn’t comment immediately, while an Indian Oil spokesman declined to comment. National Iranian Oil Co.’s public relations office in Tehran didn’t respond to an email and two calls seeking comment.
