The US Treasury issued 30-day sanctions waivers on 12 March permitting any country to purchase approximately 124 million barrels of Russian oil already at sea, with the window running through 11 April 1. The waivers began on 5 March covering Indian refineries before expanding globally a week later. Treasury Secretary Scott Bessent called the measure "narrowly tailored" but told Sky News that Russian revenue gains were "an inevitability" 2.
The waivers arrive against a transformed price environment. In January, Urals crude traded below $38 per barrel against Brent at $62.50, and Russian oil revenues had fallen roughly 32% year-on-year . The Iran conflict reversed that trajectory. Brent reached approximately $103 per barrel by 18 March — a 65% increase — driven by the near-collapse of tanker traffic through the strait of Hormuz. Analysts at Rapidan Energy and Wood Mackenzie have called this the largest energy supply disruption since the 1973 oil embargo 3. The IEA's 400-million-barrel strategic reserve release — its largest-ever coordinated drawdown — failed to arrest the climb. Prices briefly touched $126 at peak.
European leaders responded in terms that left little ambiguity. German Chancellor Friedrich Merz — who told Trump on 3 March that Europe would not accept Ukraine terms negotiated without European participation — stated: "Easing sanctions now, for whatever reason, is wrong." European Council President António Costa said the move "impacts European security." Zelenskyy warned Russia could earn "$10 billion" over a fortnight. From Moscow, RDIF head and Special Presidential Envoy Kirill Dmitriev pushed the opposite direction, arguing the global energy market "cannot remain stable" without Russian oil 4.
The waivers expose a structural contradiction in Western sanctions policy. The regime was designed to constrain Russian revenue during a period of low oil prices. The Iran war has created conditions where every barrel Russia sells generates more revenue than the sanctions architecture was built to prevent — and where the US itself needs Russian crude on the market to contain domestic energy costs. The peace talks that froze when the Iran conflict began remain suspended; the sanctions leverage built for those negotiations is now eroding under the weight of an unrelated war. The 11 April expiry date will test whether the waiver was genuinely temporary or whether market pressure makes renewal politically unavoidable.
