Oil remains a key input for transport fuels, industrial feedstocks and backup power use during price spikes across South-East Europe. In 2025, the region’s oil system is described as almost entirely net import dependent, with refining capacity and logistics infrastructure shaping trade flows and price exposure. Across Slovenia, Croatia, Hungary, Serbia, Romania, Bulgaria, Bosnia and Herzegovina, Montenegro, Albania, North Macedonia and Greece, import volumes, refinery output and fuel price trends align with differences in domestic processing capability.
Slovenia and Croatia: import dependence versus refinery throughput
Slovenia’s petrol, diesel and jet fuel consumption in 2025 is around 1.1–1.3 million tonnes per year. With no domestic crude production or refinery capacity, Slovenia relies on pipeline and road imports of products from Croatia and Italy. The lack of refining means local price exposure follows global Brent moves and European refining margin conditions. In early 2025, Brent traded in the $80–90 per barrel range, while wholesale diesel prices in Slovenia corresponded to about €1.00–1.20 per litre at the pump.
Croatia’s annual oil product demand in 2025 is estimated at 3.2–3.6 million tonnes. Its refining system, historically anchored by Rijeka and Sisak facilities and restructured in recent years, still processes several million tonnes of crude annually for gasoline, diesel and jet fuel. Effective refining throughput in 2025 is about 2.7–3.0 million tonnes per year, supported by crude imports via the Adriatic system and maritime terminals for seaborne shipments. Diesel wholesale prices at the rack typically fall within €0.92–1.15 per litre, while retail petrol prices are around €1.05–1.30 per litre.
Croatia’s refined output also supports exports to Bosnia and Herzegovina and Slovenia at roughly 0.2–0.4 million tonnes per year. Exports are often oriented toward diesel and aviation turbine fuel. The same port-based access that supports domestic supply is reflected in rack-level pricing compared with inland markets.
Hungary and Serbia: regional exports from refining scale
Hungary is described as the largest refining and product exporter within the subregion in 2025. Domestic oil product consumption is about 7.8–8.5 million tonnes annually, while MOL refiners process roughly 9–10 million tonnes of crude per year. This scale enables exports of surplus petrol, diesel and middle distillates into Slovakia, Austria, Croatia and parts of western Ukraine markets. In 2025, Hungarian product exports are around 1.4–1.8 million tonnes, with diesel typically dominating.
Diesel rack prices in Hungary during mid-2025 have ranged around €0.88–1.10 per litre, while consumer pump prices have been about €1.05–1.35 per litre. The source attributes lower levels versus some peripheral Balkan markets to refining scale and distribution efficiency rather than changes in demand fundamentals.
Serbia’s oil demand in 2025 is approximately 3.6–4.1 million tonnes of oil products. The Pančevo refinery processes about 2.8–3.0 million tonnes, leaving the remainder to be imported as finished products rather than supplied entirely by domestic processing. This reduces acute scarcity risk but does not remove price volatility for retail fuels.
Serbian petrol and diesel pump prices in 2025 typically sit between €1.10–1.40 per litre, influenced by Brent movements, regional logistics margins and excise tax policy. Product imports are primarily diesel at about 0.7–1.0 million tonnes per year, sourced from Croatia, Hungary and occasionally Greece depending on seasonal arbitrage.
Romania and Bulgaria: refining surplus into neighbouring markets
Romania’s position is described as structurally stronger than most peers due to domestic production and refining activity in 2025. Consumption runs near 10–11 million tonnes per year, while Romanian refineries process roughly 8–9 million tonnes of crude annually. Domestic crude output contributes several tenths of a million tonnes to the feedstock pool even as it declines from its mid-2010s peak.
The refining surplus enables exports of about 0.8–1.2 million tonnes per year, predominantly diesel, when spreads support outbound flows. Romanian retail prices for diesel and petrol in 2025 typically range between €1.00 and €1.30 per litre. The source links these ranges to smaller logistics margins alongside domestic refining scale.
Bulgaria’s refining sector remains a supplier to Western Balkans markets in 2025 as domestic demand approaches 4.5–5.0 million tonnes. Bulgarian refineries process about 4.0–4.3 million tonnes of crude, producing gasoline, diesel and heating oil for domestic coverage and neighbouring supply needs.
Bulgaria’s exports of refined products in 2024–2025 are estimated at 0.3–0.6 million tonnes per year, primarily diesel into Serbia, North Macedonia and Bosnia depending on price spreads and logistics costs. Retail price levels across 2025 are typically around regional norms at roughly €1.05–1.35 per litre for diesel and petrol, with short volatility episodes tied to crude spikes or wider refining margins.
Bosnia-Herzegovina through North Macedonia: reliance on imported products
Bosnia and Herzegovina remains heavily reliant on external product imports during 2025 operations described as limited for effective refining infrastructure use. Annual demand sits around 1.2–1.6 million tonnes, driven by transport and industrial needs that are met largely through imports from Croatia, Serbia or Hungary.
The source estimates that in 2025 product imports total roughly 1.1–1.4 million tonnes annually, covering nearly all domestic needs with bulk shipments often comprising diesel and gasoline. Wholesale prices for imported diesel before excise typically range from €0.95 to €1.20 per litre, while retail figures often exceed €1.20 per litre. Distribution costs and lower competitive pressure are cited as factors behind retail levels.
Montenegro has consumption under 0.4 million tonnes in 2025, with no functional refinery identified for the market’s supply chain needs described here as fully import dependent. Diesel, petrol and LPG are sourced primarily through Croatia with occasional direct maritime shipments when available.
Pump prices in Montenegro are structurally higher than neighbours at roughly €1.20–€1.55 per litre. The source attributes the level to small market scale alongside higher unit logistics costs and tax structures rather than changes in regional benchmark pricing alone.
Albania’s demand is around 1.5–1.8 million tonnes annually, with product imports approximating that volume because refining activity is limited and unstable despite a history of crude production elsewhere described only as “history.” Refined products are sourced primarily via Greece, Italy and Croatia with annual imports near 1.4–1.7 million tonnes in 2025.
Pump prices at the Albanian market generally range between €1.15 and €1.45 per litre, reflecting marine freight costs, import margins and excise tax levels stated within the source facts provided here.
North Macedonia’s consumption is estimated at about 1.7–2.0 million tonnes annually, fully covered by imported products in this account of 2025 supply structure without domestic refining base support described here as absent for pricing context only where stated explicitly later for pump drivers rather than as a separate claim about infrastructure beyond that point.
The country imports roughly 1.6–1.9 million tonnes of diesel, petrol and LPG in 2025 mainly via Bulgaria and Greece; pump prices for diesel commonly range from €1.20 to €1.50 per litre. Logistics margins, tax structure and lack of a domestic refining base are listed as influences on those ranges.
Greece: refinery throughput supporting product security exports
Greece is presented as one of the most significant oil markets in South-East Europe based on consumption size combined with refining capacity access routes described here through Aspropyrgos and Thessaloniki facilities plus maritime crude import routes used for product security positioning within the region.
Total consumption in Greece during 2025 is around 10–11 million tonnes. Refinery throughput is near 8.5–9.2 million tonnes, with surplus products exported at roughly 0.6–1.0 million tonne per year when global margins permit.
The source indicates Greek retail fuel prices track European benchmarks closely but benefit from scale; average diesel prices at the pump commonly settle within €1.05–€1.30 per litre. Robust throughput alongside competitive inland distribution are cited as factors supporting those ranges despite global crude volatility.
Southeast Europe-wide dynamics: Brent-driven pricing and regional trade volumes
The regional oil trade picture across South-East Europe in 2025 is described as shaped less by scarcity than by structure affecting price exposure under near-universal net import dependence stated earlier for the region overall.
