Kazakhstan halts oil exports after tanker strikes

After drone strikes hit tankers at Russia's Novorossiisk terminal, Kazakhstan prepared to halt exports through the CPC pipeline — its main crude route to European markets. The weak point in Europe's post-invasion energy shift is now exposed: refiners replaced Russian oil with Kazakh oil, but the oil still exits through Russian territory into a sea where both sides are attacking ships.

Three Strikes, Then Silence

The Caspian Pipeline Consortium, a multinational venture carrying mainly Kazakh crude to a loading terminal on Russia's Black Sea coast, suspended operations twice in three days. On 19 July, drones struck two tankers during loading. CPC briefly resumed, then stopped again on 20 July after a third vessel was hit (S&P Global, BOE Report). By 21 July, Kazakhstan was preparing to stop pumping altogether because tanker companies refused to send vessels into the area (Bloomberg).

CPC's shareholders include KazMunayGas, Chevron, ExxonMobil and Shell alongside Russia's Lukoil (CPC). European refiners have treated CPC Blend as a practical substitute for sanctioned Russian barrels (EIA). The barrel's passport says Kazakhstan. Its geography says Russia. And it is tanker companies, not governments, who decide whether ships sail into a drone zone.

Berlin's Refinery Problem

Germany shows what route risk means for actual fuel supply. The PCK refinery in Schwedt, which supplies Berlin, Brandenburg and parts of western Poland, lost access to Kazakh crude via the Druzhba pipeline in July. The missing volumes covered about one fifth of processed oil; a substitute delivery from South America held utilization near 80%, according to the Federal Economy Ministry (Zeit). Berlin insists there is no fuel emergency.

The government is now re-examining a pipeline upgrade from Rostock to Schwedt that would bypass Russian-controlled routes entirely. The project is stuck: EU rules restrict Berlin from subsidising the infrastructure if the benefit flows to Rosneft Deutschland, the Russian-owned company that still operates PCK under German government control (Zeit).

The Risk Is Not Confined to One Terminal

On 21 July, a drone struck the propane tanker Gas Lisbon in the western Black Sea while heading to Ukraine's Danube port of Reni. Romania rescued all 17 crew (Euronews, tagesschau). The hit occurred in Romania's exclusive economic zone, where it has resource and safety jurisdiction but not full sovereignty. That legal distinction makes a NATO military response unlikely; the probable path is surveillance and deterrence (BBC). Bulgaria, Romania and Turkey already run a trilateral mine-countermeasures task group expanding toward infrastructure protection (Armymedia). But naval patrols do not solve the structural problem.

Route risk also sharpens political bargaining inside the EU. The 21st sanctions package against Russia remained unresolved in mid-July, with the oil price cap among contested items (ANSA). EU sanctions require unanimity (any single government can hold up the package), and Greece has reportedly blocked provisions banning Russian LNG transport to protect its specialized shipping sector, even as Greek-interest tankers were among the vessels struck near the CPC terminal (Euronews, Newsit). Each disruption also gives Hungary's Viktor Orbán a ready-made argument: according to Telex, Budapest bought €591 million of Russian energy in June, and Orbán frames continued Russian imports as necessity, even when Hungary's own reserves data show no supply crisis (Portfolio).

Europe changed the owner of its oil. It did not change the geography of the route. Until alternative pipelines and loading infrastructure exist outside the Black Sea war zone, that gap between label and location is where European energy security breaks.
