Why it matters: New U.S. sanctions are forcing India and China, Russia's biggest oil customers, to choose between cheap crude and the entire U.S. dollar-based financial system.

💥 Driving the news: The Trump administration sharply escalated economic measures against Moscow on Wednesday, sanctioning Russian oil giants Rosneft and Lukoil.

  • The goal is to cripple Vladimir Putin's war machine and drive him to the negotiating table with Ukraine.

  • Oil prices immediately jumped more than 5% as the measures reverberated through global energy markets.

The big picture: Since the 2022 invasion of Ukraine, India and China have become the primary buyers of Russian seaborne crude, snapping up about 80% of its total exports.

  • This trade, often at a discount, has funded about a quarter of Moscow's federal budget.

  • India's Reliance Industries alone has earned a windfall of about $6 billion over three years from the cheap oil.

🛑 State of play: The world's largest refiners are already hitting pause.

  • India's Reliance Industries, owner of the world's largest refinery, said it would "recalibrate" imports and is considered unlikely to "take a chance" on U.S. punishment.

  • The Indian government has also privately asked refiners to start cutting down on Russian imports.

  • China's state-backed operators have also paused most purchases, though smaller independent refiners may continue and some traders believe the pause may be temporary.

🏦 How it works: The U.S. is threatening "secondary sanctions" on any "participating foreign financial institutions" that deal with Rosneft and Lukoil.

  • For global companies like Reliance, this means risking losing access to U.S. capital markets and dollar-based financing—a risk many see as too great.

"This is an attempt to put pressure on Russia. No self-respecting country ever does anything under pressure."

Nov. 21: The deadline given by the U.S. Treasury for companies to wind down their dealings with the sanctioned firms.

🔮 What's next: Analysts expect a sharp drop in Russian oil purchases starting next month.

  • While China will likely continue some pipeline imports, it's not expected to absorb the massive volume India is set to drop.
