A 14.42% increase in the price of Russian gas supplied to Bosnia and Herzegovina has turned the country’s diversification debate into an immediate commercial issue. The increase applies to third-quarter deliveries from Gazprom Export to the state-owned importer Energoinvest, which supplies consumers in the Federation of Bosnia and Herzegovina.
Bosnia is entirely dependent on Russian gas entering through Serbia and the Turkish Stream system. Annual consumption is no more than about 250 million cubic metres, while estimated payments to Gazprom reach approximately €75 million a year. The gas enters at Šepak and travels through infrastructure built almost fifty years ago towards Sarajevo and central Bosnia.
Applying the same 14.42% increase to the full estimated annual bill would imply an additional cost of roughly €10.8 million, although the actual 2026 impact will be lower or higher depending on the duration of the quarterly price and future contractual revisions. For an economy with a relatively small gas market, that remains a meaningful burden.
The Federation is promoting the Southern Interconnection, which would connect Bosnia with Croatia and provide access to the Krk LNG terminal. The strategic argument is clear: a second route would reduce the ability of one supplier to determine price and contractual conditions.
The commercial case is more complex. Bosnia’s total gas demand is modest compared with the capacity normally required to support a new international pipeline. Construction costs would need to be recovered through tariffs paid by a limited consumer base unless the route attracts new industrial demand, gas-fired power generation or transit volumes.
Long-term LNG supply arrangements would also be necessary. Access to Krk does not automatically produce cheaper gas. Bosnia would pay for the LNG commodity, terminal capacity, Croatian transmission, the interconnector and its domestic network. The alternative route creates competition and security, but its delivered price will depend on utilisation and contracting.
Political fragmentation remains the largest structural obstacle. The Federation’s Energoinvest and Republika Srpska’s Gaz-Res maintain separate supply relationships. Republika Srpska has extended its agreement with Gazprom on what it describes as preferential terms, although detailed pricing has not been disclosed. A national diversification strategy is difficult when the two entities pursue different commercial and geopolitical approaches.
The interconnection therefore needs a governance model capable of surviving political change. Ownership, regulated tariffs, capacity allocation, procurement rules and cross-entity access must be settled before lenders can assess the project. Dependence on grants without a durable operating structure would only postpone the underlying problem.
Industrial policy should form part of the solution. New gas-consuming investments in district heating, flexible electricity generation or manufacturing could improve utilisation, but they would also need to remain compatible with Europe’s decarbonisation direction. A pipeline designed today must avoid becoming an underused asset before its debt is repaid.
Bosnia’s current dependence gives Gazprom substantial pricing power. The Southern Interconnection can reduce that exposure, but only when the physical route is supported by transparent contracts, sufficient demand and a regulatory framework accepted across the country.
