Market evolution: Diesel fuel (CN 27101931) — 2015–2025

Introduction

This report examines the evolution of EU external trade in gas oils (customs code CN 27101931) over the period 2015–2025. Gas oils — a category that encompasses diesel fuel and related middle-distillate products — sit within the broader chapter of petroleum oils and preparations (CN 271019). The EU has historically been a major net importer of gas oils, relying heavily on external suppliers to meet its refining-deficit needs, particularly for middle-distillate fuels used in transport, agriculture, and industry.

The eleven-year window under review spans several transformative episodes: the post-2015 oil-price downturn, the COVID-19 demand shock, and most decisively the geopolitical upheaval triggered by Russia's invasion of Ukraine in 2022, which prompted sweeping EU sanctions on Russian petroleum products. The data reveals a market that contracted in overall scale, radically reoriented its sourcing geography, and experienced sharp price volatility and structural shocks along the way.

1. A Decade of Contraction: The Long Decline in EU Gas Oil Trade Volumes

The EU remains a structural net importer of gas oils

Throughout the entire period, the EU ran a persistent trade deficit in gas oils. In 2015, the trade balance stood at approximately −€1.54 billion. By 2025, the deficit had narrowed to −€873 million, an improvement of 43.4%. However, this narrowing was driven less by a surge in EU competitiveness than by a parallel decline on both sides of the ledger.

Both imports and exports contracted sharply

EU imports of gas oils fell from 3.83 million tonnes (€1.63 billion) in 2015 to 1.57 million tonnes (€906 million) in 2025 — a decline of 59.0% in volume and 44.2% in value. Over the same period, the minimum recorded import volume was 1.26 million tonnes, confirming that 2025 levels remain well above the trough. Exports contracted even more steeply: from 172,313 tonnes (€81.7 million) to 53,923 tonnes (€33.1 million), a drop of 68.7% in volume and 59.5% in value.

Unit prices rose, masking some of the volume decline

While volumes fell, unit prices moved in the opposite direction. Import prices rose from €425 per tonne in 2015 to €577 per tonne in 2025 (+35.9%), and export prices climbed from €474 to €613 per tonne (+29.3%). The maximum recorded import price reached €891/t and the maximum export price €2,647/t during the period, reflecting the extreme price spikes of 2022. The value decline therefore understates the contraction in physical volumes that the EU is actually moving across its external borders.

EU member-state roles shifted significantly

Greece emerged as the dominant EU importer of gas oils from outside the bloc, increasing its share from €482 million in 2015 to €803 million in 2025 (+66.5%), likely reflecting its role as a refining and bunkering hub in the Eastern Mediterranean. By contrast, several major economies effectively exited the import market: Germany's imports fell from €171 million to virtually zero (−100.0%), France from €39 million to near zero (−100.0%), and the Netherlands from €131 million to €6.5 million (−95.1%). On the export side, the Netherlands remained the largest EU exporter but saw a decline from €60.7 million to €26.7 million (−56.0%).

2. From Russia to the Rest: The Radical Reorientation of EU Import Sources

Russia was the overwhelmingly dominant supplier until 2022

In 2015, the Russian Federation supplied €1.56 billion of gas oil imports — accounting for the vast majority of EU external imports. Russia's share was so large that the import concentration index (HHI) stood at 9,637 in 2015 — a level indicating a highly concentrated, near-monopolistic sourcing structure (the HHI maximum for a single supplier is 10,000). This dependence was a defining structural feature of the EU's gas oil market for years.

EU sanctions triggered a near-total collapse in Russian imports

The invasion of Ukraine in February 2022 and the subsequent adoption of EU sanctions on Russian petroleum products (including the February 2023 embargo on refined products) fundamentally altered the trade landscape. By 2025, Russian gas oil imports had fallen to just €7.9 million — a decline of 99.5% from 2015 levels. A price shock was detected in Russian imports centred on 2022, with an abnormality score of 4.2 and a price shift of +122.8%, reflecting the spike in crude and product prices combined with the risk premium attached to Russian-origin barrels.

Four new suppliers filled the vacuum

The departure of Russia created an urgent need for alternative sourcing, and the data shows four countries stepping into the breach with dramatic growth rates:

Iraq's surge from a marginal supplier to the single largest non-Russian source at €429 million is particularly notable, likely reflecting the expansion of Iraqi refining capacity and the country's strategic positioning as a diesel exporter to Europe. Turkmenistan, Türkiye, and Qatar — all negligible suppliers in 2015 — collectively contributed over €616 million by 2025, suggesting that EU importers actively diversified across Caspian, Middle Eastern, and Eastern Mediterranean routes.

Import concentration fell dramatically

The Herfindahl-Hirschman Index for imports collapsed from 9,637 in 2015 to 3,298 in 2025 — a decline of 65.8%. This is one of the most striking structural shifts in the entire dataset. An HHI of 3,298 still indicates a moderately concentrated market (above the 2,500 threshold considered "highly competitive"), but the transformation from near-monopoly to diversified sourcing within a decade is remarkable. The minimum recorded HHI was 3,007, suggesting the diversification has largely stabilised.

Export concentration moved in the opposite direction

While import markets became more competitive, EU export concentration actually increased, with the export HHI rising from 8,973 to 9,872 (+10.0%). This reflects the fact that EU gas oil exports became increasingly concentrated on a small number of destinations — predominantly the United Kingdom, which remained the top export partner throughout the period despite declining from €77.3 million to €32.9 million (−57.5%). Gibraltar and a handful of smaller destinations accounted for the remainder.

3. Price Volatility, Geopolitical Shocks, and the Specialisation Landscape

Two major price shocks punctuated the decade

The volatility analysis reveals two standout shock events:

1. EU exports to the United Kingdom (2021): An extraordinary price shock with an abnormality score of 39.7 and a price shift of +1,788.1%. The value share of this shock was 100%, indicating it dominated the entire export series. This likely reflects the post-Brexit adjustment period and the extreme tightness in the UK's gas oil supply chain during 2021, when post-COVID demand recovery, logistics disruptions, and the new trade-border frictions combined to create a seller's market.

2. EU imports from Russia (2022): A price shock with an abnormality of 4.2 and a price shift of +122.8%. This aligns with the global energy price surge following Russia's invasion of Ukraine and the initial rounds of sanctions.

Trade partners exhibited high and heterogeneous volatility

The coefficient of variation (CV) across import sources ranged widely. Among major suppliers, Russia showed moderate volatility (CV 0.53), while Iraq (1.22), the United Kingdom (1.80), and Malaysia (2.00) displayed high instability. On the export side, Nigeria (CV 2.82), Tunisia (2.65), and Brazil (2.25) were among the most volatile destinations — consistent with episodic, opportunistic rather than structural trade relationships.

Italy and the Netherlands led EU specialisation in gas oil exports

The specialisation analysis for 2025 shows that Italy displayed the strongest comparative advantage, with a Revealed Comparative Advantage (RCA) of 6.76 and a Normalised RCA (RSCA) of 0.74 — indicating that gas oils account for a substantially higher share of Italy's exports relative to the EU average. The Netherlands (RCA 1.71, RSCA 0.26) and Belgium (RCA 1.68, RSCA 0.25) also showed moderate specialisation. At the other end, large economies such as Germany (RCA 0.0003, RSCA −1.00) and France (RCA 0.23, RSCA −0.63) were net importers with virtually no outward specialisation in the product, consistent with their domestic consumption patterns and refining configurations.

Conclusion

The EU gas oil market over 2015–2025 has been reshaped by three converging forces: long-term volume contraction, a radical supply-chain reorientation away from Russia, and episodic but severe price shocks.

The overall scale of trade diminished significantly, with import volumes falling by 59% and export volumes by 69%. Unit prices rose by roughly 30–36%, cushioning the value decline but reflecting the increasing cost of sourcing gas oils from more distant and fragmented suppliers.

The most transformative event was the effective elimination of Russian supply — a source that once accounted for the overwhelming majority of EU gas oil imports. The resulting vacuum was filled by a rapid influx from Iraq, Turkmenistan, Türkiye, and Qatar, driving the import HHI from 9,637 to 3,298. This diversification, while geopolitically significant, has also introduced new risks: several of the replacement suppliers show high trade volatility (CVs above 1.0), and the relationships appear less mature than the long-standing Russian pipeline.

Looking ahead, the data suggests the EU's gas oil trade has entered a new structural regime: smaller in volume, more diversified in origin, more expensive per unit, and more exposed to geopolitical volatility from the Middle East and Central Asia. The resilience of this new configuration will depend on whether the EU can deepen and stabilise these alternative supply relationships — or whether further disruptions lie ahead.
