Kazakhstan has ceased oil shipments via the Caspian Pipeline Consortium (CPC) to a crucial Russian Black Sea export terminal following Ukrainian attacks on tankers. The CPC pipeline typically transports over a million barrels daily from Kazakhstan, representing about 80% of its total oil output, to Novorossiysk. This route is vital for Kazakhstan's oil exports. However, recent attacks have deterred vessels from reaching the terminal, leading CPC operators to halt operations, according to traders.

Ukraine claimed responsibility for numerous attacks on Russian vessels in the Sea of Azov. Kazakhstan's Energy Ministry condemned the attacks, noting two tankers loading Kazakh crude, ASIA and NISSOS IOS, were hit by drones. The halt in supplies is expected to impact Kazakhstan's oil-dependent economy, which had already revised its crude output projections downward due to earlier attacks on the terminal.

International oil companies like Chevron and Exxon Mobil are stakeholders in CPC. The disruptions come as global oil markets face volatility from escalating tensions in the Strait of Hormuz and threats to Red Sea shipping lanes. Kazakhstan has been seeking alternative export routes amid fears of sanctions targeting Russia, but its geographical constraints limit options.
