Washington targets Rosneft and Lukoil to choke war funding as the Kremlin stages a major nuclear exercise. A canceled Trump-Putin summit adds to market uncertainty, driving crude prices higher.
WASHINGTON/MOSCOW – Global markets reacted with fresh volatility Wednesday as the United States escalated economic pressure on Russia, sanctioning its two largest oil companies, Rosneft and Lukoil. The move, aimed at crippling Moscow’s ability to finance its war in Ukraine, coincided with a major Russian military exercise involving its nuclear forces.
The new sanctions represent a significant shift in White House policy, coming just one day after a planned summit between U.S. President Donald Trump and Russian President Vladimir Putin was abruptly canceled.
“Now is the time to stop the killing and for an immediate ceasefire,” said U.S. Treasury Secretary Scott Bessent.
The U.S. Treasury Department stated the sanctions were designed to “damage Moscow’s ability to fund its war machine.” For months, the Trump administration had resisted pressure to target Russia’s energy sector directly, hoping for a diplomatic breakthrough. With the war grinding on for three years and eight months, that patience appears to have run out.
Market Impact: Oil and Defense Surge
The news immediately rippled through commodity and equity markets.
- Crude Oil: Prices extended gains following Secretary Bessent’s comments, with benchmarks jumping by more than $2 a barrel. The targeting of Rosneft and Lukoil, central pillars of Russia’s economy, introduces significant new uncertainty to global energy supplies.
- Defense Stocks: Shares in European defense companies rose on the news of the failed diplomatic summit. Investors are betting that the collapse of peace talks signals a protracted conflict, necessitating higher military spending by Western governments supporting Ukraine.
This investor sentiment was reinforced by Sweden’s announcement that it had signed a letter of intent to export Gripen fighter jets, manufactured by Saab (SAABb.ST), to Ukraine.
Diplomacy Stalls, Missiles Fly
The economic escalation comes amid a collapse in high-stakes diplomacy. The Trump-Putin summit, announced unexpectedly last week, was canceled after U.S. officials said Moscow reiterated hardline peace terms. Sources told Market Insider that Russia demanded Ukraine cede control of the entire southeastern Donbas region, a non-starter for Kyiv and a rejection of Trump’s proposal to freeze the conflict at the current front lines.
President Trump told reporters he canceled the meeting because “it didn’t feel right to me,” adding he did not want a “wasted meeting”—a sentiment the Kremlin said Putin shared.
As diplomacy faltered, Russia showcased its military might. The Kremlin released video of General Valery Gerasimov, head of the General Staff, reporting to Putin on drills involving Russia’s nuclear triad. The exercises included the launch of intercontinental ballistic missiles, submarine-launched missiles, and test firings from strategic bombers.
Russia’s Defence Ministry also noted its Tu-22M3 bombers flew over the Baltic Sea, shadowed by NATO aircraft, in a clear warning to the Western alliance, which is also conducting its own nuclear deterrence exercises this month.

Allies Tighten the Screws
The U.S. is not acting alone. On Wednesday, European Union countries approved their 19th package of sanctions against Russia, which notably includes a ban on Russian liquefied natural gas (LNG) imports, further targeting Moscow’s energy revenues.
On the military front, European support for Kyiv continues to solidify. While Trump reiterated he is “still not ready” to provide Ukraine with long-range Tomahawk missiles, allies are stepping in. Ukrainian President Volodymyr Zelenskiy said he expects to acquire at least 100 Swedish Gripen jets, which could be operational by next year.
Looking ahead, the market faces a landscape of heightened geopolitical risk. With the U.S. and EU now targeting the core of Russia’s energy economy and Moscow responding with nuclear posturing, investors are bracing for sustained volatility in energy markets and continued momentum in the defense sector.
