Executive Summary
The UK and EU's simultaneous creation of sanctions carve-outs for Russian fuel while the US intensifies Iranian oil restrictions reveals a fundamental breakdown in coordinated sanctions discipline driven by the Iran war energy crisis. The UK has issued indefinite-duration trade licences allowing imports of Russian jet fuel and diesel refined in third countries, directly contradicting its previous commitment to close sanctions loopholes. This policy reversal coincides with Iran's closure of the Strait of Hormuz disrupting 20% of global oil supplies and 25% of seaborne oil trade. The erosion of secondary sanctions coordination suggests that when energy security pressures mount, allied unity collapses in favor of selective compliance and national interest prioritization .

Regional Energy Crisis Context
Since February 28, 2026, Iran has closed the Strait of Hormuz in retaliation for US-Israeli military operations, launching missile attacks on Gulf states and laying sea mines while the US simultaneously blockaded Iranian ports. This closure eliminated transit for 20% of global oil trade and significant LNG volumes, forcing QatarEnergy to declare force majeure on export contracts and triggering what the International Energy Agency called "the largest supply disruption in the history of the global oil market".
The energy crisis created immediate policy contradictions. The UK carve-out effectively enables fuel shipments from major hubs like India and Turkey that process discounted Russian crude, while also issuing temporary licences for Russian LNG from Sakhalin-2 and Yamal plants through January 2027. Ukraine's head of sanctions policy disagreed with the UK approach, stating that "pressure on Russia should only increase, while market stability should be ensured by addressing root causes, Hormuz".
Secondary Sanctions Architecture Under Stress
In the context of a shifting international order, secondary sanctions effectiveness depends significantly on the responses of targeted third-party actors, who increasingly pursue selective engagement or open resistance rather than universal compliance. The US has played a pivotal role in sanctioning Russia's military-industrial complex and evasion networks through third countries, with the Biden administration blacklisting the lion's share of the Russian shadow fleet and leveraging the global dominance of the US financial system through secondary sanctions.
Secondary sanctions function more effectively than direct sanctions by leveraging the power and scale of US and allied economies, making them harder to circumvent with broader reach that strikes deeper into adversarial logistical chains. However, Iran's shadow fleet has grown more efficient with voyage times shortened from 85-90 days to 50-70 days through optimized routing, demonstrating that Iran can ramp exports when sensing windows of opportunity, undermining sanctions designed to limit funding for destabilizing activities.
The UK policy reversal exemplifies this breakdown. The Amendment Regulations do not prescribe due diligence standards required of importers to determine whether refined products derive from Russian crude, with guidance expected to follow on whether this will mirror equivalent EU standards. This regulatory gap creates opportunities for sanctions circumvention through definitional ambiguity.

Key Expert Perspectives
Energy security experts and sanctions specialists agree that the Iran crisis has exposed fundamental tensions between maintaining sanctions integrity and ensuring energy supply security. However, they diverge on whether current policy reversals represent temporary crisis management or permanent strategic realignment.
Areas Of Expert Agreement
- The Strait of Hormuz closure represents the largest energy disruption since the 1970s
- Secondary sanctions effectiveness requires consistent allied coordination
- Energy crises create inevitable pressure on sanctions regimes
Areas Of Expert Disagreement
- Duration assessment: Some view UK carve-outs as temporary crisis response; others see permanent policy shift
- Effectiveness impact: Debate over whether current coordination breakdown significantly undermines sanctions architecture
- Alternative mechanisms: Disagreement on whether BRICS payment systems and third-country facilitation represent viable long-term circumvention methods
Systematic-Expert Alignment
Alignment: MIXED The systematic analysis aligns with expert concerns about sanctions coordination under energy pressure but places greater emphasis on the structural nature of the breakdown compared to expert assessments that focus more on temporary crisis dynamics.
| H1: Temporary crisis-driven accommodation preserving sanctions framework | UK describes measures as crisis response; "periodic review" language; immediate reversal pledges by officials | "Indefinite duration" licence terms; no consultation with allies; pattern of expanding rather than limiting carve-outs | POSSIBLE (25-35%) |
| H2: Structural breakdown revealing sanctions architecture vulnerabilities | Complete surprise to EU; public allied criticism; energy security prioritization over coordination | Previous successful crisis management; continued US sanctions intensification; EU permanent legislation approach | LEAD (45-55%) |
| H3: Deliberate policy realignment toward energy security priorities | Rational response to supply realities; protection of economic interests; alignment with national security doctrine | Public apologies for handling; criticism from own party members; contradiction of stated policy goals | low confidence (15-25%) |
Counterarguments
-
Crisis temporality argument: The UK and EU actions may represent rational crisis management rather than fundamental policy shifts. However, the "indefinite duration" language and lack of clear termination criteria suggest policy accommodation extending beyond immediate crisis response.
-
Sanctions effectiveness resilience: The US continues aggressive sanctions expansion, suggesting the regime remains potent. Yet this ignores that secondary sanctions effectiveness depends critically on allied unity, which is demonstrably fracturing.
-
Energy transition acceleration: The crisis may ultimately strengthen sanctions by accelerating renewable energy adoption and Russian energy independence. This overlooks the immediate revenue flows to Russia during the critical transition period when coordinated pressure is most needed.
Key Assumptions
| Assumption | Rating | Impact if Wrong |
|---|---|---|
| Allied energy security concerns will continue prioritizing over sanctions coordination | SUPPORTED | If false, rapid restoration of sanctions discipline could restore deterrent effect |
| Iran crisis will persist through 2026 maintaining energy supply pressure | REASONABLE | If resolved quickly, pressure valve removed but damage to coordination precedent remains |
| Secondary sanctions require allied unity to maintain effectiveness | SUPPORTED | If unilateral US sanctions remain effective alone, coordination breakdown less significant |
| Russian revenue flows through carve-outs are significant | Volume data unavailable; impact assessment depends on actual revenue scale |
Indicators To Watch
| Indicator | Current State | Warning Threshold | Time Horizon |
|---|---|---|---|
| Additional UK/EU sanctions carve-outs announced | One major carve-out (fuel) | Two or more additional sectors exempted | 60-90 days |
| US secondary sanctions targeting allied entities | None currently | US designation of UK/EU entities facilitating Russian trade | 90-180 days |
| EU member state bilateral energy deals | Limited reporting | Public announcement of direct Russian energy agreements | 30-60 days |
| Strait of Hormuz reopening negotiations | Stalled | Active diplomatic engagement with concrete timelines | 30-45 days |
| Chinese refineries processing Iranian crude volumes | Estimated high levels | Open acknowledgment of expanded Iranian crude processing | 60-90 days |
| BRICS alternative payment mechanism usage | Limited data | Announcement of operational alternative to SWIFT for energy trades | 180-270 days |
Decision Relevance
Scenario A (~55%): Continued fragmented sanctions enforcement — Recommended action: Prepare for reduced sanctions effectiveness by developing alternative pressure mechanisms including diplomatic isolation and targeted asset freezes. Monitor third-country facilitation closely and develop contingency plans for key supply chain vulnerabilities.
Scenario B (~30%): Formal sanctions regime breakdown — Recommended action: Accelerate development of autonomous sanctions capabilities and alternative enforcement mechanisms. Consider bilateral rather than multilateral sanctions frameworks and prepare for openly competitive sanctions regimes among former allies.
Scenario C (~15%): Allied coordination restoration after Iran crisis resolution — Recommended action: Maintain current assessment frameworks while preparing rapid restoration of coordinated enforcement. Document current circumvention methods for post-crisis plugging of regulatory gaps and enhanced due diligence requirements.
Analytical Limitations
- Volume data for Russian fuel flows through third-country refineries remains classified or unavailable, limiting precise assessment of carve-out impact on Russian revenues
- Chinese independent refinery compliance with secondary sanctions threats cannot be verified through open sources, creating uncertainty about deterrent effectiveness
- UK and EU internal policy deliberations are not transparent, making it difficult to assess whether current measures represent temporary accommodation or permanent strategic shift
- The timeline for Strait of Hormuz resolution remains highly uncertain, affecting duration of energy supply pressure on sanctions coordination
- Secondary sanctions effectiveness measurement lacks standardized metrics, complicating assessment of coordination breakdown impact on overall regime success
