US secondary sanctions target Russia's $734m daily oil revenue
New US tariffs on nations trading Russian energy threaten to sever the export lifeline propping up a collapsing domestic war economy.
The US is advancing legislation to sanction buyers of Russian oil, natural gas and uranium, imposing heavy tariffs on third-party nations that trade in these commodities. The legislation targets Russia’s primary financial artery: fossil fuel exports that generate €734 million a day. For a $2.6 trillion economy already shrinking on a quarterly basis, losing this revenue stream could be devastating.
Moscow is grappling with a massive fiscal black hole. Defence spending has surged from roughly $47 billion annually between 2019 and 2021 to over $158.5 billion this year, with officials telling President Vladimir Putin the war is running $28 billion over budget. Stanford researcher David Henderson estimates the total cost of the conflict has exceeded $2.5 trillion, effectively burning through GDP to gain territory at a rate of about $90 million per square mile.
The drive to fund this expenditure has fractured the domestic economy. The military sector is overheating, while the civilian sector stagnates. Half of all civilian industrial sub-sectors are in decline, with output falling in 19 out of 21 sectors outside of pharmaceuticals and transport equipment. Civilian firms are trapped between borrowing costs near 20%, war-inflated wage demands for scarce labor, and a consumer market crippled by inflation.
Consumer prices are surging, with overall inflation hitting a five-month high of 6% and services inflation reaching 10.6%. Grocery costs alone jumped 18% between 2024 and 2026. Compounding the crisis is a severe labor shortage. With military casualties estimated at over 1.4 million killed, wounded, or missing, and 650,000 citizens having fled the country, factories cannot fill critical production roles.
A recent surge in oil prices provided only a temporary reprieve. As crude fell below $73 a barrel in early 2025, budget revenues from oil and gas halved by January 2026. While the outbreak of the Iran war pushed Brent crude up 55% to near $120 a barrel, it came at a strategic cost. The resulting chaos forced Russia to halt two power plants in Iran, alongside oil and gas exploration and planned transit routes to India.
To bridge the gap, Russia has liquidated 71% of its gold reserves as of January, wiping out post-pandemic economic gains. The central bank has cut its key rate by 25 basis points to 14.25%, but borrowing costs remain prohibitively high. Growth is projected to fall to just 0.4% in 2026, down from 1% this year. Without its energy revenues, Russia's capacity to sustain its military output and prevent broader economic unraveling will face its most severe test yet.
