Russia's EU pipeline share fell to 8% before Ukraine even shut the last transit route

Russia's EU pipeline share fell to 8% before Ukraine even shut the last transit route With Russian flows through Ukraine now halted and storage at 95%, Europe's diversification problem has shifted from supply panic to absorbing a record glut. Ukraine halted the transit of Russian gas to European customers on Wednesday (2026-05-13), after the prewar transit deal expired at the start of the year and was not renewed. The pipeline had carried roughly 14 billion cubic metres a year to remaining EU buyers, and its closure removes one of the last physical links binding Russian supply to the continent.^3,7 That matters because the volumes Europe must now replace are smaller than the headline crisis suggests, and the scramble to backfill them risks locking in the wrong solution. Before the war, Russia supplied nearly 40% of the EU's pipeline natural gas. By 2023 that share had already collapsed to about 8%, according to EU Commission data.³ The cut-off is real, but it lands on a market that has spent three years adjusting to it. The proposed fixes are running into arithmetic. The European Union is exploring whether to route Azerbaijani gas through the same Russian pipelines crossing Ukraine, according to sources cited by Bloomberg.⁴ Yet Azerbaijan does not have the spare volumes to make the swap work. Naftogaz has said only about 2 bcm of the 14 bcm the EU received via the Ukraine route could realistically be replaced by Azeri supply in the short term, leaving the bulk of the gap to be filled elsewhere.⁵ Elsewhere means LNG, and the tankers are already here. European storage is currently 95% full, with more gas waiting to be unloaded from a fleet of vessels idling off the coast, according to The Economist.² That picture is hard to square with the language of crisis. Five months ago the talk was of rationing and economic devastation as Russian flows plummeted; now the immediate problem is finding somewhere to put the cargoes that arrived in response.² The diplomatic risk is that Europe talks itself back into dependence. Analysts at CEPA warn that Ukraine and its Western allies are drifting toward a deal that would feed the Kremlin's war machine and hand Moscow renewed leverage for energy blackmail, precisely the outcome the transit halt was meant to foreclose.⁶ A swap arrangement that keeps Russian-controlled pipelines full, even with relabelled Azeri molecules, would undercut three years of weaning. The case for the swap is narrower but not trivial. Ukraine earned transit fees from Russian gas crossing its territory, revenue initially expected to reach $7.15 billion over the life of the contract, and Kyiv loses that income with the route shut.⁵ Several landlocked central European buyers also lack easy access to LNG terminals, which is why the idea of keeping the physical pipeline alive under a different flag keeps resurfacing despite the political objections. On the Russian side, the lost European market is not being cleanly replaced. Russian gas output fell 3.2% to about 334.8 bcm by mid-year, Bloomberg reported, even as exports via the Power of Siberia pipeline to China are projected to rise more than 20% to the line's maximum capacity of 38 bcm a year.¹ LNG production slipped 5.1% to around 16.5 million tonnes over the same period.¹ China is buying more, but not enough to offset the European volumes Moscow has lost. For traders the signal is in the spread between the crisis narrative and the inventory data. A market sitting on 95% storage with floating cargoes waiting to discharge is not short gas.² The directional signals in the underlying flow data are genuinely mixed, with no clear bullish or bearish consensus emerging from the supply picture. The risk is asymmetric into a cold snap or a fresh outage, but the base case is a well-supplied summer. The structural shift the cut-off accelerates is toward LNG and renewables rather than any pipeline swap. The Bruegel analysis frames the end of Ukraine transit as forcing exactly that reckoning for the EU's remaining Russian-dependent members.⁷ Whether they take the LNG path or quietly negotiate the molecules back through Ukraine under an Azeri label is the question now in front of Brussels. Watch the Azeri swap talks. If the 2 bcm Naftogaz floated becomes the ceiling, the deal is marginal and the LNG-and-renewables trajectory holds. If Brussels stretches it toward the full 14 bcm, that is a tell that Europe is choosing the cheaper pipeline over the more secure cargo, and the political cost will arrive later.^5,4
