In brief
- Trump struck a deal on 9 October for Russia to supply 300,000+ tonnes of diesel, backed by an OFAC licence running to April 2027.
- Russia's ability to deliver is in doubt after Ukrainian drone strikes hit refining capacity, while a further Trump sanctions waiver triggered a 60-day US review and Ukrainian criticism.
- Reported Russia-Iran military ties raise the risk of a reinforcing cycle, where easing pressure on Moscow indirectly sustains both conflicts.
In October 2026, Washington’s efforts to contain the economic consequences of the Iran war intersected with its policy towards Russia. On 9 October, US President Trump announced an agreement for Russia to supply more than 300,000 tonnes of diesel to US and international markets. The announcement sought to address elevated fuel prices ahead of November’s congressional elections, but drew criticism from Ukraine and US lawmakers concerned that easing restrictions would benefit Moscow despite its continuing invasion of Ukraine.
The agreement received regulatory support through OFAC’s General License 135, which authorises transactions relating to the sale, delivery, offloading and importation of Russian-origin diesel otherwise prohibited under two specified Russia-related sanctions programmes. The authorisation runs until 7 April 2027, representing a targeted, temporary relaxation rather than a termination of the wider sanctions framework.
The potential supply benefit remains uncertain. On 12 October, Reuters reported that Russia’s ability to meet the initial request depended on refining capacity affected by Ukrainian drone strikes. This creates a strategic complication, with Ukraine’s efforts to constrain Russian fuel production potentially conflicting with Washington’s objective of increasing supply to alleviate energy pressures arising from the Iran war.
On a broader scale, diplomatic consequences are still unfolding. On 14 October, Kremlin envoy Kirill Dmitriev portrayed the agreement as opening the way to wider US–Russia economic cooperation. The prospect raises concerns that energy affordability could displace pressure on Russia as a US priority, while providing Moscow with an opportunity to challenge its international isolation.
The controversy subsequently widened when President Trump waived additional Russia-related sanctions and tariffs before they took effect. On 18 October, Secretary of State Marco Rubio said the administration would take up to 60 days to assess the economic implications of that broader waiver. Washington presented its approach as compatible with efforts to end the war. Ukrainian President Zelensky, however, argued that the waiver would prolong hostilities, highlighting competing assessments of whether commercial incentives or sustained economic pressure offer greater leverage over Moscow.
Russia’s relationship with Iran adds a further dimension to the matter, with Iranian drone supplies and technology reportedly supporting Russia’s campaign in Ukraine. Reporting has also indicated that military assistance has subsequently flowed in the opposite direction, with the Associated Press reporting that Russia was supplying Iran with upgraded drones bolstered by developments made during the Ukraine war. Reuters has also reported on Russian targeting support for Iran, while distinguishing that broader assistance from unproven involvement in particular attacks.
These dynamics create a potentially reinforcing cycle. To the extent that Russian assistance helps Iran sustain its operations, it may contribute to a prolonged conflict whose disruption of energy markets increases demand for Russian supplies and pressure for sanctions relief. Improved export opportunities could, in turn, strengthen Moscow’s capacity to sustain its own military commitments and provide resources potentially available for further assistance to Iran. This remains an assessment of how the conflicts may reinforce one another, rather than evidence of a coordinated strategy.
Prolonged energy disruption therefore risks making sanctions increasingly negotiable, allowing Moscow to extract commercial and diplomatic benefits from a conflict involving a state it supports. Whether Washington secures meaningful Russian concessions in return will help determine whether this approach strengthens its leverage or inadvertently reinforces the relationships sustaining both conflicts.
