Energy markets are frequently described as places where prices are set through exchange trading, based on bids and offers. During periods of stress, physical logistics and industrial constraints can become the main factor in price formation. In those conditions, signals from exchanges may carry less weight than operational bottlenecks.
Logistics constraints that limit arbitrage
Tanker availability, port congestion, pipeline capacity, and storage constraints determine what can be moved in practice. These limits cannot be removed by financial arbitrage when physical capacity is tight. When constraints tighten, markets may clear at prices that appear inconsistent with supply and demand curves. The exchange can still reflect scarcity, but the underlying driver is infrastructure rather than market fundamentals.
Refinery operations and refined product availability
Refinery decisions influence the availability of refined products used for transport, shipping, and backup power generation. Planned or unplanned refinery outages can remove significant volumes from the market quickly. If logistics are constrained, the resulting shortfall may not be corrected through imports in time. Prices then adjust sharply because supply cannot reach required locations rather than because demand has increased.
Impact on South-East Europe’s regional balances
In South-East Europe, disruptions are amplified by reliance on a limited number of refineries and transit routes. A single outage can change regional balances by shifting where imports must come from and increasing their cost. Freight rates rise and delivery times extend as a result. Energy-intensive industries can face sudden cost increases, with effects spreading into gas and electricity markets as industrial demand patterns shift.
LNG shipping competition and downstream price effects
LNG logistics add another layer to the same supply chain pressure. LNG shipping competes for tanker availability with other energy cargoes, and freight costs affect LNG economics. When oil-related disruptions tighten logistics, LNG netbacks can deteriorate and cargoes may be diverted away from Europe. Gas prices respond to these changes, followed by electricity market outcomes.
Power price spikes linked to fuel delivery bottlenecks
In scenarios where fuel logistics become the binding constraint, power prices can spike even if local generation capacity appears sufficient. The timing and location of fuel deliveries matter when refined products or gas cannot move as expected. This can lead to abrupt adjustments across interconnected markets rather than gradual rebalancing.
Why futures and spot signals can diverge
Exchange-based indicators may not capture physical constraints ahead of time. Futures markets can reflect expectations, but they cannot resolve bottlenecks in ports, pipelines, or storage. When logistics dominate, spot prices can decouple sharply from forwards. Price volatility increases as participants react to real-time limitations outside exchange pricing mechanisms.
Binary operational events and rapid propagation
Operational decisions during stress periods often occur in a binary way rather than through marginal adjustments. A refinery either runs or it does not, and a tanker either arrives on time or it does not. These discontinuities tend to create price jumps instead of smooth changes. In an integrated energy system, such jumps propagate quickly across multiple fuels and regions.
Policy limits when infrastructure is the constraint
For policymakers and regulators, smoothing prices may be difficult when physical constraints are the root cause. Releasing strategic reserves or changing market rules cannot immediately create logistics capacity or restore refinery output. Recognising when exchange pricing is being overpowered by operational realities is presented as important for an effective response.
Infrastructure resilience in Southeast Europe
The region’s exposure to logistics-driven shocks reflects physical limitation rather than market failure. As energy systems become more interconnected and depend on global supply chains, logistics dominance during stress periods is expected to increase. For Southeast Europe, that dependence is tied to the availability of refineries, transit routes, and transport capacity needed to move fuels into downstream markets.
