Russia to Stop Kazakh Oil Transit via Druzhba Pipeline, Threatening Berlin s Key Refinery
At a glance
- •Russia will prohibit transit of Kazakh crude via the Druzhba pipeline to the PCK Schwedt refinery from May 1, 2026.
- •PCK Schwedt supplies a large share of diesel, petrol and heating oil for Berlin, making the disruption politically sensitive.
- •The refinery has alternative supply routes (ports such as Rostock and deliveries via Poland), reducing total dependency on Druzhba.
- •Shifting supplies to maritime and western overland routes could raise costs, freight demand and crude differentials.
- •The incident underscores energy transit vulnerability and may accelerate EU efforts to diversify crude sources and bolster strategic stocks.
Russia will halt Kazakh crude flows through Druzhba
Germany has confirmed that Russia will block the transit of Kazakh crude oil through the Druzhba pipeline to the PCK Schwedt refinery as of May 1, 2026. The German Federal Network Agency said Rosneft Germany informed it that, following instructions from the Russian Ministry of Energy, the transit of Kazakh crude via Russian territory will be prohibited. Reuters first reported the development on April 21, citing multiple industry sources.
The PCK Schwedt refinery supplies a large share of diesel, petrol and heating oil consumed in and around Berlin, making the pipeline disruption politically and economically sensitive. Since 2022 the refinery had increased imports of Kazakh crude delivered across Russia, which helped diversify supplies after previous disruptions tied to sanctions and changing trading patterns following Russias invasion of Ukraine.
Impact, alternatives and market implications
Despite the significance of the Druzhba route, the refinery is not wholly dependent on Kazakh crude transported overland. Much of PCKs feedstock now arrives by ship via ports such as Rostock and through deliveries from Poland. Those maritime and western overland routes give the plant some resilience, but they can be more expensive, slower, and capacity-constrained especially during periods of high demand.
For the wider German and European fuel markets, an abrupt cut in pipeline-borne Kazakh crude could tighten local diesel and heating oil availability, at least temporarily, and put upward pressure on regional refined product margins. Traders will likely seek increased shipments from North Sea, US and other global suppliers to close the gap, which could push freight and crude differentials higher.
Beyond immediate market moves, the decision highlights how energy logistics remain vulnerable to diplomatic and regulatory decisions along transit corridors. Policymakers and supply managers in Germany and the EU may accelerate efforts to further diversify crude sourcing and strengthen strategic stocks to buffer against such transit risks.
On the diplomatic front, Berlin will face pressure to coordinate with EU partners and international suppliers to avoid winter-time shortages and to reassure consumers about heating and transport fuels. Commercial operators will assess the economics of shifting longer-term supply contracts away from transit-dependent routes and invest in logistics flexibility where feasible.
In short, while the May 1 measure poses a meaningful challenge to Schwedts historical supply patterns and to local fuel security, alternative shipping and supply arrangements exist that can mitigate the worst effects albeit at higher cost and with potential short-term market disruption.
