Ukraine hit a small service vessel at the Caspian Pipeline Consortium oil terminal in the Black Sea, continuing a campaign of drone strikes against energy infrastructure that has rattled global oil markets and infuriated Kazakhstan, a country that had nothing to do with the war but now finds its economic lifeline under fire.

The CPC terminal, located near the Russian port city of Novorossiysk, handles the vast majority of Kazakhstan’s crude exports. Disrupting it, even briefly, sends ripples through global energy supply chains.

What the CPC terminal actually is, and why it matters

The Caspian Pipeline Consortium operates a roughly 1,500-kilometer pipeline stretching from Kazakhstan’s Tengiz oil field to the Black Sea coast. The terminal at its endpoint is where that crude gets loaded onto tankers and shipped to world markets.

Kazakhstan routes approximately 80% of its total crude exports through this single corridor. That volume represents more than 1% of global oil supply.
