India’s days of buying cheap Russian oil could be over.

Sweeping sanctions by the U.S. against Russia’s energy companies and operators of vessels that transport oil will complicate Indian efforts to keep importing cheap Russian crude and could push up inflation in Asia’s third-largest economy, analysts said.

The country could be looking at a potential oil shock, said Bob McNally, president of Rapidan Energy Group.

“India will be more affected than China by sanctions, since India imports much greater amount of its oil from Russia than China,” he told CNBC.

Last Friday, the U.S. Treasury announced sanctions on two Russian oil producers, along with 183 vessels which are primarily oil tankers that have been shipping barrels of Russian crude. At present, tankers sanctioned by the U.S. are still permitted to offload crude oil until March 12.

The South Asian nation imported a significant 88% of its oil needs between April and November 2024, little changed from a year earlier, according to government data. Around 40% of those imports came from Russia, data from trade intelligence firm Kpler showed. 

Out of the newly sanctioned 183 tankers, 75 of them have transported Russian oil to India in the past, according to data provided by Kpler. Just last year alone, the 183 sanctioned tankers transported around 687 million barrels of crude, of which 30% were shipped to India.

“Most of these barrels went to Indian refiners and, hence, the impact will likely be largest there,” BNP Paribas’ senior commodities strategist Aldo Spanier said in a research note following the sanctions.

The new U.S. sanctions were deeper and broader than foreseen by markets, and the disruptions are expected to amplify, Spanier added.

India’s Ministry of Petroleum and Natural Gas did not respond to a CNBC request for comment.

The sanctions are also coming at a time when India is tipped to surpass China as the number one oil consumer in the world in 2025, accounting for 25% of total oil consumption growth globally.

Increasing demand for transportation fuels and home cooking fuels is set to spur this growth of 330,000 barrels per day this year — the most of any country, forecasts by the U.S. Energy Information Administration showed. 

India consumed 5.3 million barrels per day in 2023, EIA’s most recent data showed. This consumption is expected to have increased by 220,000 barrels per day last year.

India wasn’t always this dependent on Russian oil.

As recently as 2021, Russian oil accounted for just 12% of India’s oil imports by volume. By 2024, that share had spiked to 37.6%, Muyu Xu, senior oil analyst at Kpler told CNBC.

The catalyst for increased oil imports was the Ukraine war, which prompted some Western countries to impose sanctions against Russia and curtail their purchases of Russian crude. As prices of Russian oil fell, India was able to hoover up supplies cheaply from companies that were not under sanctions.

The discount of Russia’s crude, Urals, to the global benchmark Brent has averaged around $12 per barrel from last August to October, according to S&P Global’s most recently published data last November. In 2024, Russia’s Urals were also cheaper by $4 per barrel compared to oil from Iraq, one of India’s main sources of crude oil imports, data from Kpler showed.

“If India were to fully comply with U.S. sanctions, we could see a sharp decline in Russian crude arrivals in February and potentially March,” Xu added.

Supply disruptions to India could be as high as 500,000 barrels per day, Rystad Energy’s senior analyst Viktor Kurilov shared via email.

Additionally, as Donald Trump’s inauguration draws closer, the world’s supply of cheap Iranian crude, is also facing the risk of tighter sanctions. Iran made up 4% of the world’s oil production in 2023, according to an EIA report released last year.

“It is [also] a bit of a double whammy for the key importer [India] as Iran will likely face new sanctions pressure with the incoming Trump administration,” Helima Croft, global head of commodity strategy at RBC Capital Markets, told CNBC.

If the new sanctions are coupled with a potential curb on Iranian crude, Brent prices could rise even higher to $90 per barrel, Goldman Sachs wrote in a note published after the announcement of the sanctions.

The Indian economy is “significantly vulnerable” to fluctuations in oil prices, a research paper published in 2023 established. Domestic retail prices of gasoline and diesel surge “like rockets” in response to rising crude oil prices, Abdhut Deheri, assistant economics professor at the Vellore Institute of Technology and M. Ramachandran from Pondicherry University’s department of economics said in the research paper.

Analysis from the Reserve Bank of India in 2019 found that every $10 per barrel rise in oil prices could lead to a 0.4% increase in headline inflation. 

“High oil prices, if passed to consumers, could further hurt their purchasing power at a time when income and GDP growth have slowed,” Dhiraj Nim, an economist at ANZ. 

However, weak consumer demand could deter producers from passing on the cost burden to consumers, which means it could dent companies’ profits instead, Nim added. Although if the government chooses to shoulder the additional costs, it would strain its finances.

Not only will China and India have to pay more for the oil they consume, they will need to pay more to have it delivered to their shores because oil tanker rates have also risen, said Andy Lipow, president of energy consultancy Lipow Oil Associates.

Combined with a stronger U.S. dollar and weaker rupee, the impact on the India economy will be magnified, said Lipow. 

India’s rupee recently plunged to a record low as a result of pressure from a strong greenback and selling by foreign portfolio investors. 

The country is no stranger to protests over high fuel prices. In 2018, widespread protests across the country against record-high petrol and diesel prices led to the closure of businesses and schools  in several regions.
