“India will look to continue Russian Crude imports, but perhaps it has reached its limit, hampering any additional barrels,” according to Janiv Shah, senior analyst at Rystad Energy.

Since the Kremlin’s invasion of Ukraine in February last year, India’s refiners have been snapping up discounted Russian oil.

Moscow has since leapfrogged to become India’s leading source of crude oil, accounting for about 40% of India’s crude imports. June marked the 10th consecutive month-on-month increase in India’s imports of Russian crude, data from commodity intelligence firm Kpler showed.

“An unprecedented feat in recent history, especially given the volumes in question — 2.2 million barrels per day in June,” Kpler’s lead crude analyst, Viktor Katona said.

And that’s the highest volume that India’s imports of Russian oil can go — at least for the rest of the year, according to his predictions.

“I would say 2.2 million b/d will be the peak this year… We believe India’s imports of Russian crude will see a slight downward correction to two million barrels per day. That will be the sustainable level of buying,” he said. .

However, the volume of crude oil consumed and processed by India’s refineries has now hit a “seasonal peak” and would only trend downwards from here, Rystad Energy’s Shah told CNBC in an email.

His sentiments were echoed by Katona, which highlighted that in addition to refineries being currently shut down, demand for oil is set to trickle down too.

“For the first time this year, some of Indian refiners will be undergoing maintenance which was just not the case in January to May 2023 when there were no turnarounds at all. Everyone was firing on all cylinders,” said Katona.

India’s monsoon season started in early June, and the summer period is often associated with lower demand for oil products as a result of lower mobility and construction, Katona added.

Fuel demand in India, the world’s third largest oil consumer, usually enters a lull during the four-month monsoon season. India’s total oil demand in June slipped 3.7% month-on-month to 19.31 million tonnes, according to data from India’s Petroleum Planning and Analysis Cell.

And it seems the limit goes both ways.

Flows coming out of Russia have a “finite limit,” said Daniel Hynes, senior commodity strategist at ANZ.

“Any additional supply coming out of Russia … that flows into Asia, I suspect it’s done. It’s maximum amount now,” he added.

Russian oil exports fell 600,000 barrels per day to 7.3 million barrels per day in June — the lowest since March 2021, according to a recent report by the International Energy Agency.

Russia also pledged to trim its crude oil exports earlier in July.

“India has talked about the inability to really pick up significantly additional cargoes from Russia,” Hynes added.

However, that’s not to say that India’s refiners will not attempt to try for another all-time high import of Russian oil next year, said Kpler’s Katona.

“Most probably in the March-to-May period again,” he said, pointing out that demand at that time will be “unrestricted from the Indian side and Russian export availability will be once again boosted by refinery turnarounds.”

However, India needs to maintain its relationship with other exporters too, especially key suppliers in the Middle East.

According to Rystad data, 55% of India’s recent seaborne medium sour imports were from Russia, while imports from the Middle East sank to a “historic low of 40%.”

“India may be approaching a limit in its reliance on Russian crude, as it would still need to secure long-term supply agreements with Middle Eastern suppliers,” Shah said.

Crude imports from the Middle East region dropped 21.7% to 8.68 kilo tonnes in June compared to the start of the year, data from Refinitiv showed.

Medium sour crude supplies to India tend to come under annual term contracts, which have minimum purchase agreements.

“Technically, the Indians could be buying more, but they don’t want to antagonize the Middle East too much,” said Kpler’s Katona. “Politics matter, too,” he said.

However, Indian buyers are particularly price-sensitive, and could still forsake other countries’ crude for Russia’s at the right price.

Indian refiners can always take more Russian [crude] at the expense of other grades, eg the Middle Eastern ones, if the price disparity widens,” said director of Refinitiv Oil Research in Asia, Yaw Yan Chong.

Russian exports to India have soared more than 10 times since February last year, shooting from a pre-invasion average of just 350,000 metric tonne per month to a post-invasion average of 4.57 million metric tonne per month from March 2023 onwards, he said.

Yaw expects India will still pursue Russian imports at elevated levels “for as long as Russian.” [crude] are under [sanction] and shunned by their traditional European buyers.”
