In 2025, oil continues to be a fundamental element in the energy landscape of South-East Europe, significantly influencing both economic stability and energy security. The region is characterized by a heavy reliance on oil imports, as domestic production remains limited. The interplay between refining capabilities, logistical networks, and market access plays a crucial role in shaping trade flows and price volatility across countries such as Slovenia, Croatia, Hungary, Serbia, Romania, Bulgaria, Bosnia and Herzegovina, Montenegro, Albania, North Macedonia, and Greece.
Slovenia’s oil consumption is primarily met through imports. With an estimated annual demand of 1.1 to 1.3 million tonnes for petrol, diesel, and jet fuel in 2025, Slovenia lacks both crude production and refining capacity. Consequently, it relies heavily on pipeline and road imports from neighboring Croatia and Italy. The absence of local refining means that Slovenia’s oil prices are closely tied to global Brent crude fluctuations; early 2025 saw Brent prices fluctuating between $80-$90 per barrel. Retail diesel prices hovered around €1.00 to €1.20 per litre.
Croatia’s refining infrastructure supports both domestic needs and exports. With an annual demand of approximately 3.2 to 3.6 million tonnes of oil products, Croatia’s refineries process about 2.7 to 3 million tonnes of crude annually. This capacity allows Croatia not only to meet its domestic demand but also to export refined products—primarily diesel—to neighboring countries like Bosnia and Herzegovina and Slovenia. In 2025, wholesale diesel prices ranged from €0.92 to €1.15 per litre due to favorable port access.
Hungary stands out as the largest refining hub in the region. Processing roughly 9 to 10 million tonnes of crude annually allows Hungary’s MOL refiners to export significant quantities of petrol and diesel—estimated at about 1.4 to 1.8 million tonnes in 2025—to markets including Slovakia and Austria. Diesel rack prices were reported between €0.88 and €1.10 per litre wholesale while retail prices ranged from €1.05 to €1.35 per litre.
Serbia benefits from domestic refining but remains reliant on imports. The Pančevo refinery processes around 2.8 to 3 million tonnes of oil products annually against a total demand of approximately 3.6 to 4.1 million tonnes in 2025. While this capacity mitigates some import risks, Serbia still imports around 0.7 to 1 million tonnes primarily from Croatia and Hungary at retail prices averaging between €1.10 and €1.40 per litre.
Romania maintains a stronger oil position due to its production capabilities. With consumption levels near 10-11 million tonnes annually and domestic refineries processing about 8-9 million tonnes of crude each year, Romania can export around 0.8 to 1.2 million tonnes of refined products like diesel when conditions allow for favorable pricing spreads; retail prices typically range from €1.00 to €1.30 per litre.
Bulgaria serves as a key supplier for the Western Balkans. It processes around 4 to 4.3 million tonnes of crude annually against a demand of approximately 4.5 to 5 million tonnes in the same year; exports are primarily directed towards Serbia and North Macedonia with volumes between 0.3 and 0.6 million tonnes annually.
Bosnia and Herzegovina is heavily dependent on imported oil products. With annual consumption estimated at about 1.2 to 1.6 million tonnes, most products are sourced from neighboring countries due to limited local refining capacity; imports account for nearly all domestic needs with diesel prices typically ranging from €0.95 to €1.20 per litre wholesale before excise taxes are added.
Montenegro is fully reliant on imports for its minimal oil needs. Annual consumption is under 0.4 million tonnes without any operational refinery; thus it sources all fuel types through maritime routes mainly from Croatia at higher retail prices ranging from €1.20 to €1.55 per litre due to elevated logistics costs.
Albania’s sector remains import-dependent despite historical crude output. Its annual demand stands at approximately 1.5-1.8 million tonnes with refined product imports roughly matching that volume; retail prices have been observed between €1.15 and €1.45 per litre due largely to freight costs associated with sourcing products mainly from Greece and Italy.
North Macedonia mirrors Albania’s import dependency with similar consumption patterns. The country imports around 1.6-1.9 million tonnes annually with pump prices generally falling between €1.20 and €1.50 per litre influenced by logistics costs without any local refining capacity available.
Greece maintains significant regional influence through its robust refining sector. With annual consumption figures around10-11 million tonnes supported by refineries like Aspropyrgos processing up to approximately9-9 .2milliontonnesofcrude ,Greece also exports surplus refined products when margins allow; retail fuel prices typically range from€1 .05to€1 .30perlitre despite global price shifts owingtoits established infrastructureand distributionefficiencies .
The broader context reveals that while South-East Europe faces universal import dependence for oil products in2025 ,the structural differences among countries create varied risk exposures . Nations equipped with substantial refining capacities—such as Hungary ,Romania ,Bulgaria ,and Greece—are positioned favorably against price volatility through diversified supply channels . Conversely ,countries lacking these infrastructures face heightened price sensitivity tied closelyto global market movements .
The implications for policymakers are critical: nations with established refining capabilities enjoy advantages in negotiating market terms while pure importers must enhance logistics resilienceand stock management strategiesto mitigate external price shocks impacting consumers . In summary ,while the transition toward cleaner energy may alter long-term dynamics ,the roleof oilin shaping economic conditionsremains pivotal across South-East Europe well into2025 .
