Hungary signals supply diversification, deepening the squeeze on Gazprom's last EU buyers A push to widen Hungary's gas sourcing adds to a run of Central European exits from Russian supply, with no new Azerbaijani volumes yet contracted to fill the gap. Hungary will seek to diversify its energy supplies, Peter Magyar said, according to biz.liga.net, the clearest sign yet that the country's new leadership intends to loosen one of the EU's tightest remaining dependencies on Russian gas. The statement followed Magyar's Tisza party victory on Sunday (2026-05-17), which ended Viktor Orban's 16-year rule.² That matters because Hungary has been, alongside Slovakia, one of Gazprom's last major customers inside the bloc. A stated intent to diversify from a government that just took power on an anti-Orban platform changes the political math on Russian flows into Central Europe, even if the physical reality moves slowly.^2,1 Analysts are quick to temper expectations. Hungary's shift away from Russian energy will be gradual under new economy and energy minister Istvan Kapitany, with structural constraints outweighing the political change, they told Montel during the week of 2026-05-11. Pipelines, contracts and refinery configurations do not turn over on an election result.⁷ The direction of travel across the region is unmistakable. Slovakia, another of Gazprom's last large EU clients, is ready to sign a long-term contract with Azerbaijan, deputy prime minister and environment minister Tomas Taraba said. The intent there is the same: spread sourcing away from a single Russian dependence.⁶ Gazprom has already been losing its grip on southeast Europe. At the start of the year, Serbia began taking Russian gas through a different route via Bulgaria and the Balkans, one of three events that reshaped the regional market, according to dw.com. The company that once dominated these flows is watching its monopoly fracture.⁴ The scale of what Gazprom stands to lose is not trivial. The biggest recipients of Russian gas in the Balkans in 2019 were Croatia at 2.82 billion cubic meters, Greece at 2.41 bcm and Bulgaria at 2.39 bcm, Gazprom's own figures show. Each contract that shifts to an alternative supplier chips at a revenue base built over decades.⁴ But the supply that is meant to replace Russian gas is harder to find than the political rhetoric suggests. Azerbaijan supplied about 12 bcm to Europe through the Southern Gas Corridor in 2023, CEPA noted, and the joint EU-Azerbaijan goal of lifting that to 20 bcm a year by 2030 depends on new investment in both upstream production and the corridor itself.³ Where the additional molecules come from is the uncomfortable question. A source close to the consortium that owns the Shah Deniz field, which supplies all of the gas Azerbaijan currently exports, confirmed to Eurasianet that no new export contracts have been signed. Without fresh upstream, every cubic meter promised to a new buyer has to come from somewhere.⁵ That somewhere may be Russia itself. Azerbaijan has begun importing Russian gas, raising the prospect that some volumes badged as Azerbaijani and sold into Europe are Russian molecules rerouted, Eurasianet reported. CEPA framed the risk more bluntly: a transit arrangement that lets Gazprom keep earning roughly $5bn a year by using Ukraine and intermediaries as cover.^5,3 For Ukraine, the unwinding of Hungarian flows is manageable. Ukraine imported 2.97 bcm from Hungary last year, and traders told Montel on Wednesday (2026-03-25) that the country has several alternatives and can endure any cut in pipeline gas from Hungary, which typically covers about 40% of demand per annum.⁸ The price backdrop gives Central European buyers reason to move. ICE Endex TTF front-month traded around €48 on Friday (2026-06-05), down slightly on the day, while UK NBP firmed. Diversification is easier to commit to when the marginal European hub is well below the crisis levels of recent winters.⁶ The signals running through this market are bearish for Gazprom's European position, and the weight of evidence points one way: customers leaving, routes rerouting, monopolies splintering. Yet the replacement supply remains a question of contracts not yet signed and investment not yet made. The thing to watch is whether Hungary's stated intent turns into a tender or a long-term deal with a non-Russian supplier, or whether, like Azerbaijan's own arrangements, it quietly leaves Russian molecules in the mix.^5,3⁷
