Kazakhstan Freezes Europe Oil Route

After drone strikes hit tankers at Russia's Novorossiisk terminal, Kazakhstan moved towards halting exports through the CPC pipeline, its main crude route into European markets. For Europe, including small states such as Malta that buy energy through exposed Mediterranean and European supply chains, the weakness in the post-invasion shift is now plain: refiners replaced Russian oil with Kazakh oil, but much of that oil still leaves through Russian territory and into a sea where ships are now targets.

Three Strikes, Then Silence

The Caspian Pipeline Consortium, a multinational venture that carries 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 would not 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 workable replacement for sanctioned Russian barrels (EIA). On paper, the oil is Kazakh. In practice, its exit route is Russian. The immediate veto now sits with insurers and tanker operators, because governments can approve a trade route but cannot force commercial ships into a drone zone.

Berlin's Refinery Problem

Germany shows how route risk becomes a fuel-supply problem. 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 kept utilisation near 80%, according to the Federal Economy Ministry (Zeit). Berlin says there is no fuel emergency.

The government is now re-examining an upgrade to the Rostock-Schwedt pipeline, which would bypass Russian-controlled routes altogether. The problem is legal as much as technical. EU state-aid rules restrict Berlin from subsidising 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 it was heading to Ukraine's Danube port of Reni. Romania rescued all 17 crew (Euronews, tagesschau). The strike happened in Romania's exclusive economic zone, where Bucharest has rights over resources and safety but not full sovereignty. That distinction matters: it makes a NATO military response unlikely, leaving surveillance and deterrence as the more probable route (BBC). Bulgaria, Romania and Turkey already run a trilateral mine-countermeasures task group that is expanding towards infrastructure protection (Armymedia). Naval patrols, however, cannot remove the basic exposure.

The route risk also changes bargaining inside the EU. The 21st sanctions package against Russia was still unresolved in mid-July, with the oil price cap among the contested points (ANSA). Sanctions require unanimity, meaning any one government can hold up the package. Greece has reportedly blocked provisions banning Russian LNG transport to protect its specialised 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 presents continued Russian imports as necessity, even when Hungary's own reserves data show no supply crisis (Portfolio).

Europe changed the owner named on the barrel. It did not change the geography of the route. Until there are alternative pipelines and loading points outside the Black Sea war zone, European energy security will keep breaking at the point where the label and the route part company.
