Kazakh Crude Disruptions Drive Black Sea Tanker Rates Higher
Kazakh crude exports through the Caspian Pipeline Consortium (CPC) terminal are facing renewed pressure as repeated drone attacks disrupt loadings and push Black Sea tanker freight and war risk costs sharply higher.
According to shipbroker Gibson, CPC crude had become an important alternative source of supply at a time when Middle East loading hubs were already under pressure. However, repeated attacks on vessels loading at the terminal and on tankers elsewhere in the Black Sea have increased uncertainty around flows.
The disruption has also created an unusually large freight premium for Suezmax tankers operating in the region.
CPC Crude Exports Fall After July Attacks
CPC exports had recovered strongly after disruption earlier in the year.
During the winter period, crude export volumes averaged only around 1 million barrels per day (mbd). Operations subsequently improved, allowing exports to reach approximately 1.9 mbd in May.
That recovery came under pressure again in July.
Gibson said CPC loadings were halted three times during the month. The first interruption came on 21 July, after a drone struck a tanker at the mooring.
Further strikes followed just two days later, hitting two additional tankers. One of the vessels reportedly caught fire while loading.
With Kazakhstan having limited alternative routes capable of handling comparable volumes, the interruptions temporarily forced the country to reduce crude production.
July CPC exports consequently fell to around 1.3 mbd. That remained above winter levels but was considerably below the May peak and the 2025 average of approximately 1.5 mbd.
Loadings have continued to decline into August as periodic disruptions affect the export programme.
Mediterranean, European and Asian Flows Decline
The reduction has not been concentrated on a single destination.
According to Gibson, CPC crude flows to the Mediterranean, Northwest Europe and Asia have all declined as loading disruptions affect available cargo volumes.
This is particularly significant because CPC crude has provided an alternative source of oil during a period when global supply routes are already under considerable pressure.
The Middle East remains affected by disruption around major crude loading hubs, increasing the importance of alternative export sources such as Kazakhstan.
However, Kazakhstan has relatively few large-scale alternatives to its existing CPC export route. This leaves both production and international shipments particularly exposed when operations at the terminal are interrupted.
Black Sea War Risk Premium Surges
Security concerns are also having a significant effect on tanker operations.
Some vessels have reportedly switched off their tracking signals while loading in the region. At the same time, the exceptionally high freight premium has attracted additional vessels into the trade.
Other shipowners are avoiding the region because of the unpredictable nature of recent attacks.
Gibson noted that vessels have been struck even when their owners had no previous involvement in Russian trade. In some cases, owners were based in countries allied with Ukraine.
The absence of a clear pattern behind the attacks has increased uncertainty for shipowners assessing Black Sea voyages.
Cargo war risk insurance for CPC has also risen dramatically. According to Gibson, the cost increased roughly fivefold in three weeks, moving from around 0.2% of cargo value to approximately 1%.
Suezmax Rates Reach Around $400,000 Per Day
The impact on the Suezmax tanker market has been particularly significant.
The TD6 benchmark has climbed above WS530, equivalent to approximately $400,000 per day on a round-voyage basis.
That puts Black Sea tanker earnings at levels comparable with those seen in the Middle East.
Meanwhile, the West African TD20 Suezmax benchmark has eased in recent weeks.
As a result, the Black Sea freight premium over West Africa has widened to more than $300,000 per day.
The figures demonstrate how security risks and disruption can dramatically alter regional tanker economics even when underlying crude export volumes are declining.
Kazakhstan Has Limited Alternatives to CPC
Despite the recent interruptions, operations have so far restarted within days because damage to infrastructure has remained limited.
The importance of CPC to Kazakhstan also creates a strong incentive to restore operations as quickly as possible after any disruption.
However, previous incidents demonstrate that outages can last considerably longer. Gibson highlighted the disruption during the previous winter, which continued for around three months.
A more serious attack on the terminal's single point moorings (SBMs), port facilities or pipeline infrastructure could therefore have much wider consequences.
Such damage could remove another important source of crude from a global oil market already dealing with disruption elsewhere.
Tanker Market Faces Two-Sided Risk
For Suezmax owners, the recent disruption has generated exceptional freight earnings as security risks tighten effective vessel availability and owners demand higher rates to enter the region.
However, the same conditions could eventually work against the tanker market.
If repeated attacks cause a sustained decline in CPC exports, fewer crude cargoes would be available for transportation.
This creates a two-sided risk for Suezmax shipping. Short-term disruption can push freight rates sharply higher, but a prolonged loss of export volumes could ultimately reduce tanker demand.
For now, the ability of CPC to maintain operations remains important not only for Kazakhstan but also for a global crude market searching for reliable alternative supply routes.
