Key Takeaways:
Ukrainian drone strikes on Russia's Novorossiysk port have shut Kazakhstan's main oil export route for the third time this month, threatening nearly 1.5 million barrels a day of crude supply.
Ukrainian drone attacks on Russia's Novorossiysk port shut Kazakhstan's main oil export terminal for the third time in July, cutting off a conduit that carries about 80% of the country's crude to global markets. The Caspian Pipeline Consortium suspended tanker loadings Thursday after a Marshall Islands-flagged vessel, the Nissos Sifnos, was struck by a drone while loading Tengizchevroil crude at an offshore mooring, causing a fire that the crew extinguished with no casualties or oil spill reported.
"The CPC is an international project involving major Western energy companies and supplies significant volumes to the EU," said Aruzhan Meirkhanova, a senior analyst at Outpost Eurasia. "Kazakhstan has therefore consistently raised the stability of the corridor in its discussions with both the United States and the European Union."
The attack follows similar strikes on July 17 and 19 that hit two other tankers, forcing a weeklong shutdown that only ended July 27. The pipeline transported 64.8 million tons of Kazakh oil in 2025, accounting for 82.3% of the country's total crude exports. Among its key shareholders are Russia with 24%, KazMunayGas at 19%, Chevron with 15% and Lukoil at 12.5%.
The repeated disruptions threaten to tighten global crude supply at a time when markets are already strained by instability around the Strait of Hormuz and the Bab el-Mandeb Strait. Kazakhstan supplied 9.6% of European Union petroleum imports in the first quarter of 2026, down from 12.7% a year earlier. Romania relies on Kazakh crude for more than 60% of its supply, and interim Prime Minister Ilie Bolojan said the government expects a drop in gasoline production of as much as 15% if shipments do not resume.
No Viable Short-Term Alternatives
Kazakhstan has few options to replace the lost volumes quickly. The country's alternative export routes, including the Baku-Tbilisi-Ceyhan pipeline across the Caspian Sea, lack the capacity to absorb comparable volumes and involve higher costs and more complex logistics, according to analysts.
"Existing routes cannot absorb comparable volumes, are more expensive and involve more complex logistics," Meirkhanova said. "Realistically, the immediate priority is adaptation — strengthening contingency planning, redirecting limited volumes through alternative routes where feasible, and deploying broader anti-crisis measures."
Alexander Cooley, Claire Tow Professor of Political Science at Barnard College, said the country's alternative routes are "simply too small and too expensive to replace CPC volumes quickly, so the practical response is likely to be more diplomatic than logistical."
Diplomatic Fallout and US Involvement
The attacks have drawn an unusually sharp response from Kazakhstan, which condemned them as an "unacceptable infringement" on its economic interests. The Kazakh Foreign Ministry called for an immediate end to the strikes and urged partners to protect infrastructure used to export its hydrocarbons.
Kazakh Foreign Minister Yermek Kosherbayev discussed the CPC situation in a phone call with US Secretary of State Marco Rubio on July 29. Chevron Chief Executive Mike Wirth also approached White House officials earlier this week to address the matter, the Wall Street Journal reported, and an unnamed US official said the Trump administration warned Ukraine against attacking non-Russian ships in the Black Sea.
President Kassym-Jomart Tokayev, sitting next to Russian leader Vladimir Putin in Omsk, called for a "freeze" of the conflict and a return to negotiations under what he described as the Istanbul Formula 2.0. The last time Kazakhstan faced a similar disruption to its export infrastructure was in 2022, when a Russian court ordered the CPC pipeline to suspend operations for 30 days over an alleged oil spill violation, a move widely seen as political pressure on Astana.
