For some market participants, the announcement may appear to signal a significant easing of restrictions on Russian petroleum products. However, for international commodity traders, shipowners, insurers, reinsurers and financial institutions, the reality is considerably more nuanced.
One transaction, multiple sanctions regimes
Global commodities trading rarely involves a single legal system. A cargo may be purchased by a trader in one jurisdiction, financed in another, transported by a vessel operating under a third flag, insured through the London market and ultimately delivered elsewhere.Against that backdrop, OFAC's General License 135 removes only one layer of the compliance analysis. The licence authorises certain transactions otherwise prohibited under specified US Russia-related sanctions programmes, but it does not alter the position under UK or EU sanctions legislation.
The oil price cap
The most obvious example is the continued operation of the UK and EU oil price cap framework.The UK continues to restrict the provision of maritime transportation-related services, including insurance and other financial services, in connection with Russian oil and oil products unless the relevant price cap conditions are satisfied. Compliance is supported by detailed attestation, record-keeping and due diligence requirements.
Accordingly, the existence of a US general licence does not remove the need for insurers, brokers, traders and shipowners to assess whether a transaction remains subject to UK or EU oil price cap restrictions. A transaction that is authorised under US sanctions may still be unlawful if those requirements are not met.
Designated persons and sanctioned vessels
The same applies to transactions involving designated persons. General License 135 is not a blanket waiver of all Russia-related sanctions restrictions.Furthermore, UK and EU asset freeze measures remain fully in force. A transaction involving a designated person, an entity owned or controlled by a designated person, or a sanctioned vessel may therefore remain prohibited notwithstanding the existence of the US licence. The UK has also continued to expand restrictions targeting vessels associated with Russian sanctions circumvention and the so-called "shadow fleet", including restrictions on services relating to specified ships. As a result, compliance teams must continue to scrutinise not only the cargo but also the counterparties, ownership structures, vessel histories and sanctions status of all parties involved in the transaction.
The compliance challenge is operational, not just legal
Over the past four years, many organisations have built sanctions compliance frameworks on the assumption that Russian-origin petroleum products should generally be identified, escalated and avoided. Screening tools, underwriting processes, sanctions clauses, due diligence procedures and internal controls have all been designed around that approach.
The introduction of a US authorisation creates a more complex environment in which the answer to the question "can we do this trade?" may depend entirely on where each participant sits in the transaction chain. For multinational businesses, a transaction may be permitted from a US perspective whilst remaining restricted for UK or EU entities within the same corporate group.
For insurers and commodity traders in particular, that raises difficult practical questions:
- Can existing compliance systems distinguish between US-authorised and UK/EU-restricted activity?
- Is financing available notwithstanding the US licence?
- Will insurers and reinsurers be willing or able to support the transaction?
- Have all oil price cap requirements been satisfied?
- Are any counterparties, beneficial owners or vessels subject to sanctions restrictions?
These questions cannot be answered by reference to US sanctions alone.
A reminder for global businesses
OFAC's decision to authorise certain transactions involving Russian-origin diesel is undoubtedly significant. However, businesses should resist the temptation to view the licence as a wholesale reopening of Russian diesel trade.
For internationally active commodity traders, insurers and other service providers, the critical issue is not whether a transaction is authorised under US sanctions. It is whether the transaction is lawful and commercially workable across every sanctions regime that applies.
In many cases, UK and EU restrictions, including the oil price cap framework, asset freeze measures and vessel-related prohibitions, will continue to present significant barriers.
The result is a familiar but increasingly difficult reality for global markets: a cargo may be authorised in one jurisdiction but restricted in another. Navigating those diverging rules is no longer merely a legal exercise. For insurers, commodity traders and other market participants, it is an operational challenge that sits at the heart of modern sanctions compliance.
Continued UK sanctions escalation
The developments in the US also come against a backdrop of continued sanctions escalation by the UK. On 8 October 2026, the UK announced a further package of 38 Russia-related designations targeting oil revenues, sanctions evasion and military supply chains. Most notably, the UK designated Russian oil companies Zarubezhneft and INK Capital, meaning that, according to the FCDO, UK sanctions now cover more than 90% of Russia's oil production capacity. The package also included a further 12 shadow fleet tankers involved in transporting Russian oil, together with financial intermediaries and crypto platforms alleged to have facilitated sanctions evasion. According to the UK Government, the measures are intended both to reduce Russia's oil-derived revenues and to prevent major producers from circumventing sanctions through the rebadging of oil under non-sanctioned entities.
The timing is noteworthy. While the US licence demonstrates a willingness to deploy targeted authorisations where energy security or market stability concerns arise, the UK's latest measures underline that Western governments remain committed to increasing pressure on the Russian energy sector. Businesses involved in the production, trading, transportation, financing or insurance of Russian petroleum products therefore continue to face an increasingly complex compliance landscape, where limited licensing relief may exist alongside expanding designation activity and enforcement risk.
