What CPC Disruptions Reveal About Energy Security, Kazakhstan’s Balanced Foreign Policy

Recurrent Ukrainian drone attacks on July 17 and 19 have disrupted operations at the Caspian Pipeline Consortium (CPC), the vital artery for approximately 80% of Kazakhstan's oil exports. The attacks, which occurred at the CPC terminal on the Black Sea, led to a complete suspension of the pipeline's operations for a week, significantly raising the stakes for Kazakhstan and its international energy partners.

The Kazakh Foreign Ministry condemned the strikes, labeling them an "unacceptable infringement on Kazakhstan’s economic interests." The ministry stated that the attacks amounted to deliberate attempts to destabilize legitimate international trade, global energy markets, and transport and logistics chains. Kazakhstan urged its partners to unequivocally condemn the actions and collaborate on practical measures to safeguard the export infrastructure.

What this means for energy security more broadly is that it highlights how suddenly vulnerable export systems become when they depend on a narrow set of transit corridors. Even a major producer can be exposed if its routes to market run through suddenly politically fragile territory.

Crude oil exports via CPC resumed on July 27. However, the incident highlights the vulnerability of Kazakhstan's export systems, which rely on a narrow set of transit corridors. "What this means for energy security more broadly is that it highlights how suddenly vulnerable export systems become when they depend on a narrow set of transit corridors," said Alexander Cooley, a political science professor at Barnard College. "Even a major producer can be exposed if its routes to market run through suddenly politically fragile territory."

The CPC pipeline, a 1,511-kilometer route from western Kazakhstan to the Russian Black Sea port of Novorossiysk, is crucial for shipping Kazakh hydrocarbons to international markets. Key shareholders include Russia (24%), KazMunayGas (19%), Chevron (15%), and Lukoil (12.5%). In 2025, the system transported 64.8 million tons of Kazakh oil, representing 82.3% of the country's total crude exports.
