Russia’s War Economy Got a Reprieve From Iran

Russia’s economy entered 2026 in genuinely fragile shape. Growth is projected at just 0.4% for the year, worse than 2025’s 1% expansion, which itself narrowly avoided recession as oil prices fell below $73 a barrel and budget revenues from oil and gas halved by January 2026 (Forbes).

The Iran-war windfall

Then came an unexpected lifeline. When the Israeli-Iran conflict effectively closed the Strait of Hormuz, the Trump administration temporarily lifted sanctions on Russian-origin oil already in transit between March and June 2026 in an effort to hold down global prices (UK Parliament Research Briefing). Brent crude surged more than 55% at the peak of the Iran war, approaching $120 a barrel, and Russia’s fossil-fuel export revenues — earning roughly €734 million a day at the low point — rebounded sharply (Forbes). The Financial Times and The Economist both characterised the episode bluntly: Putin was raking in an estimated $150 million a day in extra revenue directly attributable to the war-driven price spike (UK Parliament Research Briefing).

Russia supplied approximately 300 million barrels of oil to international markets during the sanctions-waiver window, and some observers warn the episode risked entrenching new buyer dependencies on Russian crude even after the waivers expire (Atlantic Council).

The pushback: Congress moves on the toughest bill yet

That reprieve is now colliding with the most aggressive sanctions legislation of the war. The Senate voted 86-12 on 28 July 2026 to advance the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, which would impose tariffs of up to 500% on countries importing Russian oil, gas, LNG, petroleum products or coal, ban new US investment in Russia’s energy sector, and prohibit US energy exports to Russia within 30 days of enactment (OilPrice.com). The US Treasury has already moved unilaterally, sanctioning major producers including Gazprom Neft and Surgutneftegas along with more than 180 vessels tied to Russia’s shadow fleet (US Treasury).

The EU has kept pace, agreeing its 21st sanctions package on 23 July 2026, even as several member states reportedly sought carve-outs to protect domestic corporate interests — a sign that sanctions cohesion is beginning to strain three-plus years into the conflict (UK Parliament Research Briefing).

The China and India swing factor

Whether the new measures actually damage Russia’s economy depends heavily on Beijing and New Delhi. CEPA’s analysis is direct: financial workarounds exist, and the outcome hinges on whether China and India are willing to accept secondary-sanctions risk to keep buying discounted Russian crude (CEPA). If China holds firm and continues purchasing, Moscow’s dependence on Beijing deepens further; if enforcement against third countries is applied rigorously, the ruble and Russian budget face real pressure that could push the economy into recession alongside sustained high interest rates (CEPA).

Why the 2026 budget baseline may already be wrong

Notably, Russia’s own 2026 budget baseline assumed no further meaningful sanctions would materialise — an assumption the Graham bill’s Senate momentum directly undermines (CEPA). Fossil fuel taxation still accounted for roughly 24.5% of Russian federal budget revenue through the first three quarters of 2025, meaning any serious disruption to oil exports flows directly into Moscow’s fiscal capacity to sustain the war (Brookings).
