Ukraine's sustained drone campaign, the near total closure of the Strait of Hormuz, and ongoing disruption at Bab el Mandeb have created a simultaneous three front compression on global oil supply.
Russia has declared its Black Sea exclusive economic zone unsafe for navigation, and Novorossiysk has imposed an informal nighttime navigation ban.
The Strait of Hormuz is effectively closed at 5% of normal traffic, with 166–230 stranded tankers.

The global oil market is facing an unprecedented triple crisis. Ukraine's escalating drone campaign in the Black Sea, the near-total closure of the Strait of Hormuz, and the ongoing disruption at the Bab el-Mandeb Strait have converged to create the largest supply disruption in oil market history. The International Energy Agency (IEA) warns of a structural shortage of roughly 6 million barrels per day (b/d)—a deficit that could keep markets tight well beyond 2026 .
Ukraine's Drone Campaign and Russia's Navigation Warning
Ukraine has steadily expanded its naval drone operations since 2022, using uncrewed surface vessels (USVs) to target Russian warships, port infrastructure, and oil tankers in the Black Sea. Key milestones include:
November 2025: Ukrainian sea drones struck two oil tankers associated with Russia's "shadow fleet" in the Black Sea. BBC-verified footage captured explosions hitting the vessels, identified as the Kairos and Virat . A separate attack on the Caspian Pipeline Consortium (CPC) terminal near Novorossiysk disabled the deep-water mooring point SPM-2, which had a loading capacity of up to 800,000 tonnes per day .

The Strait of Hormuz is effectively closed at 5% of normal traffic, with 166–230 stranded tankers.
December 2025: Ukraine disabled another shadow-fleet tanker in its economic zone, prompting Russia to label the attacks as "piracy" and vow retaliation . Romania later neutralised a Sea Baby maritime drone that posed a threat to navigation near Constanta .
July 22–23, 2026: Russia declared its exclusive economic zone in the Black Sea unsafe for navigation, citing the threat of Ukrainian drone strikes . Simultaneously, Novorossiysk—Russia's key oil and grain export hub—imposed an informal ban on nighttime navigation between midnight and 5 a.m. .
The cumulative effect has sharply restricted Russian naval operations and commercial shipping in the Black Sea.
Impact on Kazakhstan's Oil Exports via the CPC Terminal
The Caspian Pipeline Consortium (CPC) pipeline handles roughly 80% of Kazakhstan's crude exports and represents over 1% of global oil supply . It has been repeatedly hit:
November 29, 2025: A Ukrainian drone strike severely damaged the Yuzhnaya Ozereyevka terminal near Novorossiysk, halting exports. Kazakhstan's foreign ministry urged Ukraine to cease attacks, calling them an assault on the country's economic interests . Full export capacity was not expected to return until at least December 11 . Europe lost out on 3.8 million tonnes of Kazakh oil as a result .
December 2025: Kazakhstan temporarily reduced oil shipments via the CPC due to UAV attacks and bad weather . The country rerouted some crude through the Baku-Tbilisi-Ceyhan (BTC) pipeline .
July 20–23, 2026: Fresh drone strikes on tankers at the CPC terminal forced another suspension of exports . Kazakhstan condemned the attacks and announced it had cut crude oil production—the energy ministry said "oil firms adjusted their daily output, causing a temporary drop in production volumes" . Kazakhstan's overall oil output declined to 1.63 million bpd from a July average of 2.07 million bpd .
Simultaneous Strain on Global Energy Chokepoints
This Black Sea disruption is unfolding alongside even larger crises at two other critical maritime chokepoints.
Strait of Hormuz: Since late February 2026, the strait has been effectively closed to commercial transit due to the Iran conflict. By mid-2026, AIS data confirmed traffic at approximately 5% of pre-war baseline volumes, with 166–230 stranded tankers queued on the Persian Gulf side . In 2024, oil flow through the strait averaged about 20 million b/d (roughly one-fifth of global consumption) . The Baker Institute estimates the closure is blocking or diverting some 20% of global trade in crude oil and LNG .
Bab el-Mandeb Strait: Already severely disrupted by Houthi attacks that began in late 2023, traffic recovered only slightly in 2025 before the 2026 Iran war renewed attention on the chokepoint . The World Bank documented a 15% drop in maritime traffic through the region as the conflict's shadow spread .
These two chokepoints alone handle a combined volume far exceeding the Black Sea's flows, creating a simultaneous, three-front compression on global oil transit.
IEA's 6 Million b/d Supply Shortage Warning
The IEA's warnings have escalated sharply:
March 2026: The IEA warned the Iran war was creating "the largest supply disruption in the history of the global oil market," with supply likely to plunge by 8 million b/d in March alone . Flows through the Strait of Hormuz were moving at less than 10% of pre-crisis levels .
May 13, 2026: The IEA formally overhauled its market outlook, declaring the world faces a "massive 6 million b/d oil supply shortage" that could keep markets tight well beyond 2026 even if the Iran conflict is resolved swiftly . S&P Global described the market as "severely undersupplied" and projected deficits lasting into Q4 2026 .
June 2, 2026: The IEA warned of "critically low stockpiles before peak summer demand," noting that supply gains from the Americas "only slightly mitigate the 14 million barrels per day lost from Gulf producers" . It cautioned that emergency stock releases are merely a temporary fix and not a remedy for structural shortages .
The 6 million b/d figure represents the net shortfall after accounting for all available compensatory supply—the gross disruption from the Middle East is far larger, with the IEA citing ~14 million b/d lost from Gulf producers alone .
Bottom line: Ukraine's drone campaign in the Black Sea has effectively disrupted a major global oil transit route, forcing Kazakhstan to cut production and reroute exports. This is happening in parallel with the near-total closure of the Strait of Hormuz and ongoing disruption at Bab el-Mandeb, creating a three-way compression on global oil supply. The IEA's warning of a 6 million b/d shortage—the largest in history—reflects that even if the Iran conflict were resolved immediately, markets would remain severely undersupplied well into 2027, with critically low inventories heading into peak summer demand.
