Russian Rail Curbs Put Up to $470 Million in Kazakh Coal Exports at Risk
Transit shipments of Kazakh coal through Russia toward European markets fell by 97% in two months, from 1 million metric tons in August to 30,000 in October 2026. Russian Railways approved no requests to ship Kazakh coal to Baltic ports for October or November, despite an agreement that gives qualifying shipments priority. Kazakh economist Yernar Serik estimates that up to 3.5 million metric tons of coal exports, worth $400 million to $470 million, could be at risk by year-end. The problems began in August, when shipments of Kazakh coal through Russia’s Black Sea port of Taman stopped. That left Baltic ports as the main maritime export route for Kazakh suppliers. Serik put September shipments at about 500,000 metric tons. The remaining October shipments went by rail toward Belarus and Poland, bypassing Russia’s Baltic ports. Priority Status That Failed to Secure Shipments In November 2025, Kazakhstan and Russia signed an intergovernmental agreement on rail transit and cargo handling for exports to third countries. Under Russia’s rules on access to railway infrastructure, freight volumes agreed under such treaties qualify for the fourth priority category, a relatively high ranking when the railway allocates capacity. On October 19, Kommersant reported that Russian Railways planned to cut October coal shipments to the Oktyabrskaya Railway in northwestern Russia by 80%. The newspaper obtained minutes of a Russian Transport Ministry meeting at which officials discussed the proposal. Its sources said suspending priority transit for Kazakh coal was also under discussion. Disruptions to shipping through Russia’s Black Sea ports during the war in Ukraine have led exporters to redirect freight to the Baltic, where the rail lines approaching the ports have struggled to absorb the extra traffic. Russian coal producers also face limits. The energy consultancy NEFT Research said the railway capped November coal shipments to Ust-Luga at 55% of the route’s capacity. Russia has announced no formal ban on Kazakh coal transit. Russian Railways has declined to comment on its plans for individual routes. How Much Could Exporters Lose? In 2025, Kazakhstan transported 11.7 million metric tons of coal through Russia to third countries, an increase of 27% from the previous year. The October 19 report put shipments in the first half of 2026 at 6.7 million metric tons, up 34% year over year. Serik estimated growth at 20% for the same period. According to the pricing agency Argus Media, Kazakhstan shipped 4.7 million metric tons of coal through Ust-Luga and 2.6 million through Taman between January and July. Both ports handled shipments primarily for markets in Europe and Türkiye. Serik calculated the potential shortfall using August’s shipping volume as the monthly benchmark for the rest of the year. He assumed an export price of $115 to $135 per metric ton. The estimate represents the potential value of shipments that may not take place. The actual loss to producers depends in part on how much coal they can sell in other markets and what it costs to reroute it. "In effect, Russia is not directly banning Kazakh...
