As Southeast Europe approaches 2025, the oil sector continues to play a pivotal role in the region’s energy landscape, influencing transportation fuels and industrial activities. The reliance on imports is nearly universal across countries such as Slovenia, Croatia, Hungary, Serbia, Romania, Bulgaria, Bosnia and Herzegovina, Montenegro, Albania, North Macedonia, and Greece. The interplay between refining capacity, maritime access, and storage facilities significantly shapes trade flows and price volatility. Countries with established refining infrastructures exhibit greater resilience against price fluctuations compared to those solely dependent on imports.
Slovenia’s oil consumption is projected at approximately 1.1–1.3 million tonnes annually by 2025. The country lacks domestic crude production and refining capabilities, resulting in a complete reliance on imports from Croatia and Italy. Consequently, Slovenia’s oil prices are closely tied to global Brent crude benchmarks and European refining margins. In early 2025, Brent crude prices fluctuated between 80–90 dollars per barrel, leading to retail diesel prices ranging from 1.00 to 1.20 euros per litre.
In contrast, Croatia benefits from a combination of domestic refining infrastructure and import flexibility. With an annual demand of around 3.2–3.6 million tonnes, Croatia’s refineries process approximately 2.7–3.0 million tonnes of crude each year. This capacity allows for exports of refined products to regional markets such as Bosnia and Herzegovina and Slovenia. Diesel prices in Croatia are expected to range from 0.92 to 1.15 euros per litre at the wholesale level in 2025.
Hungary stands out as the most significant refining hub in the region, processing roughly 9–10 million tonnes of crude annually to meet its domestic consumption of about 7.8–8.5 million tonnes. The country exports approximately 1.4–1.8 million tonnes of refined products each year, primarily diesel, benefiting from efficient logistics and economies of scale that keep wholesale diesel prices between 0.88 and 1.10 euros per litre.
Serbia’s oil market is characterized by its domestic refining capacity at the Pančevo refinery, which processes around 2.8–3.0 million tonnes of oil products annually while still relying on imports for the remainder of its needs (approximately 0.7–1.0 million tonnes). Consequently, Serbian fuel prices typically range from 1.10 to 1.40 euros per litre.
Romania’s position is stronger than many of its neighbors due to its domestic production and refining capabilities, with consumption near 10–11 million tonnes annually and refining output around 8–9 million tonnes. This allows Romania to export about 0.8–1.2 million tonnes of refined products yearly while maintaining competitive retail fuel prices between 1.00 and 1.30 euros per litre.
Bulgaria also plays a crucial role in supplying oil products to the Western Balkans with an annual demand of approximately 4.5–5 million tonnes and refining output of about 4.0–4.3 million tonnes in 2025. Its exports are expected to reach between 0.3 and 0.6 million tonnes per year, primarily diesel.
Conversely, Bosnia and Herzegovina remains heavily reliant on imports for its annual demand of around 1.2–1.6 million tonnes due to limited refining infrastructure; most products are sourced from neighboring countries like Croatia and Serbia.
Montenegro’s oil market is small but entirely dependent on imports for its consumption under 0.4 million tonnes annually since it lacks a functional refinery.
Albania faces similar challenges with an annual demand of about 1.5–1.8 million tonnes while relying predominantly on imports from Greece and Italy.
North Macedonia mirrors this dependency with consumption around 1.7–2 million tonnes covered entirely through imported products.
Greece maintains one of the most robust oil markets in the region with annual consumption between 10–11 million tonnes supported by significant refining capacity that processes around 8.5–9.2 million tonnes of crude each year.
The overall regional oil trade in Southeast Europe for 2025 indicates a combined import requirement of approximately 30–32 million tonnes, with over half being domestically refined before consumption or exportation.
For stakeholders in the energy sector, these dynamics underscore the importance of refining capacity and logistical efficiency in mitigating price exposure amidst global market fluctuations.
