Four years that broke the old map


Since early 2022, the Russia–Ukraine war and the escalating Iran–Israel/U.S. confrontation have combined into a twin shock that has redrawn the global energy map. Together they have fractured long‑standing trade routes, birthed parallel market systems, and injected structural volatility into pricing, logistics, and policy.


For traders, suppliers and decision‑makers, the period from 2022 to early 2026 has not just been about high prices; it has been about regime change in how energy is produced, moved, financed and regulated. Europe’s forced divorce from Russian hydrocarbons, Russia’s pivot to Asia with a growing “shadow fleet,” and Iran’s militarised brinkmanship around the Strait of Hormuz now define the risk premium across oil, gas, power and freight.



1. 2022–2023: Ukraine war turns a tight market into a structural crisis


When Russia invaded Ukraine in February 2022, energy markets were already tight from post‑pandemic recovery but relatively orderly. The war converted that tightness into a systemic shock across oil, gas and power.


Key shifts in this first phase:


  • Price shock and volatility: Fears of supply disruption and successive sanctions sent European gas and power benchmarks to record levels and drove sharp swings in crude and refined product prices as markets tested worst‑case scenarios for Russian disruption.commission.

  • Europe’s vulnerability exposed: The euro area had built heavy dependence on Russian pipeline gas and significant exposure to Russian oil, making it uniquely vulnerable to both physical cuts and policy‑driven restrictions.

  • Sanctions architecture emerges: The EU began rolling out bans on Russian coal and most seaborne crude imports, while aligning with G7 partners on an oil price cap designed to curb Moscow’s revenues without collapsing global supply.


For market participants, this was the “shock and scramble” period: sourcing alternative molecules, rewriting contracts, and reassessing credit and counterparty risk in real time.


Sanctions and counter‑measures started to crystallise into a more durable regime. Rather than eliminating Russian supply, this regime re‑channeled it and created a dual‑track global oil trade.


2. Sanctions, price caps and the rise of parallel markets


From late 2022 onward, sanctions and counter‑measures started to crystallise into a more durable regime. Rather than eliminating Russian supply, this regime re‑channeled it and created a dual‑track global oil trade.


Several mechanisms stand out:


  • Oil price cap and services restrictions: The G7–EU price cap prohibits Western shipping, insurance and related services for Russian crude sold above specified thresholds, aiming to keep volumes flowing while squeezing margins.

  • EU tightening in 2025: By mid‑2025, the EU had unilaterally cut the cap from 60 to 47.60 dollars per barrel and signalled biannual revisions based on Urals prices, adding new layers of complexity for compliance and trading strategies.

  • “Shadow fleet” expansion: To bypass sanctions and the cap, Russia and allied traders assembled a large fleet of older, opaque‑ownership tankers operating under flags of convenience; by 2025, hundreds of such vessels had been blacklisted by the EU.


The result is a bifurcated market: a “regulated” system constrained by Western law and finance, and an alternative network linking Russia, China, India, Turkey, Iran, and others that relies on non‑Western shipping, finance and insurance.


For traders, this has meant:


  • Elevated due diligence burdens on origin, blending and ship‑to‑ship transfers.commission.

  • Persistent basis differentials between benchmark grades and discounted Russian streams.

  • A premium on logistics intelligence –vessel movements, AIS gaps, and ownership structures– as drivers of both opportunity and enforcement risk.


The Ukraine war forced Europe into a historic reorientation of its energy system, affecting everything from LNG build‑out to renewables policies.


3. Europe’s pivot: away from Russian molecules, toward security and transition


The Ukraine war forced Europe into a historic reorientation of its energy system, affecting everything from LNG build‑out to renewables policies.


Core elements of this pivot:


  • Phase‑out roadmap: The EU has set a course to eliminate all Russian oil and gas imports by 2027, turning what began as a scramble into a structured but ambitious transition plan.

  • Diversification of supply: Europe has aggressively increased LNG regasification capacity, deepened ties with U.S., Qatari and African exporters, and boosted pipeline flows from Norway and North Africa to substitute Russian volumes.

  • Renewables and efficiency push: High prices and security concerns accelerated policies for renewables deployment, electrification and demand reduction, making energy security and decarbonisation mutually reinforcing in EU strategy.


Yet the picture is not linear. Russian strikes on Ukrainian power infrastructure and drone attacks on Russian oil assets have underscored the vulnerability of both fossil and power systems in a high‑intensity conflict. For European industrials and utilities, this has translated into:


  • Long‑term hedging against both commodity and capacity risk.

  • More active use of demand‑side flexibility and fuel‑switching.

  • Relocation or restructuring of energy‑intensive production where costs and volatility became unsustainable.


In Ukrania, the “energy war” is as much about electricity and infrastructure as about oil and gas.


4. Russia’s pivot to Asia and the consolidation of an alternative network


Sanctions did not remove Russian hydrocarbons from the market; they rerouted them. Over 2023–2025, Russia deepened energy ties with China, India and other non‑Western buyers, while tightening links with fellow sanctioned producers like Iran and Venezuela.


Key dynamics in this pivot:


  • Asia‑bound flows: A growing share of Russian crude exports now lands in China and India, often at a discount and with more complex shipping and financing arrangements than pre‑war exports to Europe.

  • Alliances with sanctioned peers: Russia has increasingly coordinated with Iran and Venezuela, sharing shipping capacity, marketing channels and financial workarounds to operate outside Western systems.

  • Domestic war economy: As sanctions erode export revenues and Ukraine’s drone campaign hits refineries, depots and Black Sea terminals, Moscow faces mounting pressure on the fiscal backbone of its war economy.


At the same time, Ukraine’s own grid has been devastated: all 15 thermal power plants have been destroyed or heavily damaged, and around half of hydropower facilities have suffered serious hits, undermining up to 90% of thermal capacity. This underlines that the “energy war” is as much about electricity and infrastructure as about oil and gas.


For market actors, Russia’s pivot means:


  • Growing reliance on non‑Western trading hubs for marginal barrels.

  • Geopolitical risk clustering around a coalition of sanctioned exporters.

  • A lasting wedge between transparent and opaque flows, complicating price discovery and benchmarks.


While the Ukraine war re‑engineered flows, the Iran–Israel conflict has acted as a recurrent shock generator, primarily through the risk to Gulf infrastructure and the Strait of Hormuz.


5. From Ukraine to the Gulf: Iran, Israel and the Strait of Hormuz risk premium


While the Ukraine war re‑engineered flows, the Iran–Israel conflict has acted as a recurrent shock generator, primarily through the risk to Gulf infrastructure and the Strait of Hormuz.


Key episodes and patterns since 2024:


  • Airstrikes and speculative spikes: Israeli airstrikes on Iran’s territory, framed around concerns over Tehran’s nuclear programme, have produced sharp, speculative price spikes; in one notable episode, oil jumped more than 7% in a day on fears of escalation.

  • Retaliation and narrow escapes: Iranian responses, including strikes on U.S. assets in the region, have amplified risk sentiment, though thus far core export facilities like Kharg Island have avoided direct hits.

  • Hormuz as systemic chokepoint: Around 20% of global oil trade transits the Strait of Hormuz, and Iranian political signals about the possibility of its closure consistently trigger market anxiety and temporary price surges.


Despite waves of sanctions, Iran has maintained oil exports around 1.5 million barrels per day by deploying its own shadow fleet and off‑book sales, echoing Russia’s circumvention tactics. International Energy Agency estimates indicated that even with conflict‑related tensions, Iranian exports saw only temporary dips and were compensated by inventory movements.


For traders and suppliers, the Iran–Israel front translates into:


  • A persistent options‑driven risk premium on Brent and Middle East grades around each flare‑up.

  • Elevated tanker insurance costs and routing adjustments whenever Hormuz disruption becomes more than a theoretical scenario.

  • A need to integrate sanctions flexibility and enforcement timing into trading strategies, as U.S. policy toward Iranian barrels oscillates between strict enforcement and tacit tolerance.


The Ukraine and Iran wars are distinct, but their energy impacts reinforce each other in several ways. Together they drive a more unstable and geographically fragmented system.


6. Interlocking shocks: how the two wars amplify each other


The Ukraine and Iran wars are distinct, but their energy impacts reinforce each other in several ways. Together they drive a more unstable and geographically fragmented system.


Several linkages matter:


  • Shared shadow infrastructure: Both Russia and Iran rely heavily on off‑radar tankers, complex ownership structures and sanctions‑busting logistics; disruptions to this ecosystem, whether by enforcement or incident, ripple across both supply streams.

  • Concentrated policy risk: Western sanctions and enforcement efforts now target overlapping networks of vessels, traders and financial channels, so a policy shift in Washington, Brussels or London can hit both Russian and Iranian flows at once.

  • Compounded pricing volatility: When a Ukraine‑related sanctions tightening coincides with a Gulf security scare, the market must simultaneously price in Russian discount dynamics and Middle East disruption risk, amplifying volatility in benchmark curves and spreads.


For energy companies and traders, this produces:


  • A more complex correlation structure between crude grades, shipping routes and currency baskets.

  • Greater value in cross‑basin optionality –the ability to swing barrels between Atlantic and Pacific basins as shocks migrate.

  • A strategic imperative to treat sanctions compliance, shipping risk and geopolitical analysis as integrated rather than separate disciplines.commission.


Europe’s push to eliminate Russian imports by 2027 and its broad clean‑energy agenda signal that security and transition are now intertwined.


7. Strategic implications for traders, suppliers and decision‑makers


Over the past four years, the combined impact of the Ukrainian and Iranian theatres has shifted the energy sector from a price‑centric risk model to a structural, system‑centric one.


Several strategic themes stand out:


  1. Compliance as a core trading skill: The EU’s successive sanctions packages –notably its 17th and 18th in 2025– and the evolving G7 price‑cap regime have turned compliance from a back‑office function into a frontline trading competency. Firms must track hundreds of blacklisted vessels, dynamic price caps and evolving definitions of “Russian origin” or “Iranian‑linked” crude.

  2. Logistics intelligence as alpha: With 444 “shadow fleet” vessels blacklisted by the EU by late 2025 and many more operating in legal grey zones, real‑time vessel tracking, AIS analysis and cargo‑ownership mapping now shape both opportunity and risk management. Traders who can anticipate congestion at key chokepoints or align freight and crude flows under sanctions constraints gain a material edge.

  3. Re‑pricing geographic and infrastructure risk: The destruction of Ukrainian power assets and repeated strikes on Russian oil infrastructure underscore how critical fixed assets have become combat targets rather than collateral damage. In parallel, the ever‑present threat to the Strait of Hormuz hard‑codes a geopolitical premium into Middle Eastern exports even when flows are uninterrupted.

  4. Emergence of enduring market fragmentation: Parallel systems –one anchored in Western finance, transparency and rule‑sets, the other in opaque networks connecting sanctioned states and non‑aligned buyers– appear set to persist well beyond any single ceasefire. This raises questions about benchmark integrity, data quality and the long‑term relevance of existing price discovery hubs.

  5. Acceleration of the energy transition with new fault lines: Europe’s push to eliminate Russian imports by 2027 and its broad clean‑energy agenda signal that security and transition are now intertwined. Yet the wars also incentivise some countries to double down on domestic fossil fuel extraction and stockpiling as a hedge against geopolitical shocks, creating a more uneven transition landscape.


For corporate strategy, the common denominator across scenarios is the need for flexibility in feedstock sourcing, portfolio diversification across fuels and geographies, and sophisticated geopolitical and regulatory forecasting capabilities.


8. Looking ahead: scenarios for the next phase


As of early 2026, neither the Ukraine war nor the Iran–Israel/U.S. confrontation has a clear end‑state. This uncertainty feeds directly into energy market scenarios.


Potential trajectories include:


  • Managed containment: A prolonged but geographically contained Ukraine conflict combined with an uneasy Iran–Israel stand‑off would entrench the current dual‑system market: Russian and Iranian barrels keep flowing under discount and opacity, while Western buyers deepen diversification and transition strategies.commission.

  • Escalation and chokepoint disruption: A significant incident involving Black Sea export terminals or a temporary closure or mining of the Strait of Hormuz would trigger severe price spikes, rerouting of flows around longer and more expensive routes, and potentially forced demand destruction in import‑dependent economies.

  • Gradual normalisation with persistent scar tissue: Even if ceasefires emerge in Ukraine and the Gulf, sanctions relief would likely be partial and slow. Structural changes – Europe’s pivot, the rise of shadow fleets, and non‑Western trading networks – would not simply reverse.


For corporate strategy, the common denominator across scenarios is the need for flexibility in feedstock sourcing, portfolio diversification across fuels and geographies, and sophisticated geopolitical and regulatory forecasting capabilities.



Conclusion: From episodic shock to new normal


Over the past four years, the Ukraine and Iran wars have transformed global energy from a largely integrated, efficiency‑driven system into a more fragmented, politicised and risk‑dense landscape. Europe’s accelerated break from Russian energy, Russia’s integration into an alternative network with other sanctioned exporters, and Iran’s repeated leveraging of Gulf security have together reshaped how barrels, molecules and electrons move –and how they are priced.


For traders, suppliers and energy‑sector decision‑makers, this is no longer a temporary crisis to be weathered but an operating environment to be mastered. Success will depend on marrying granular logistics and compliance intelligence with strategic positioning across regions, fuels and time horizons. The wars may one day end, but the structural shifts they have triggered in energy markets are likely to define the industry’s landscape for years to come.
