Doomsday Clock for Gulf Oil Supplies Ticks Closer as US-Iran Tanker Attacks Drive Prices Toward $100

Escalating US-Iran tanker attacks in the Strait of Hormuz have raised global oil prices toward $100 a barrel while prompting South Korea to dispatch an assessment team to the UAE as it weighs possible military contributions to secure the waterway. The doomsday clock for Gulf oil supplies ticks closer amid the mounting risks to global energy flows.

US-Iran tanker strikes intensify in Hormuz

The United States struck five Iranian oil tankers on September 8 after Iran launched ballistic missiles at a US aircraft carrier and destroyer near the Strait of Hormuz. [2] Iran retaliated by attacking a Jordanian airbase and targeting additional vessels. [3] Just three days earlier the US also hit three other Iranian tankers. [2] Those strikes followed Iranian ballistic missile launches toward a US warship. [3] Iran subsequently said it had targeted three oil tankers travelling through what it called an unauthorised route in the Strait as well as three US-linked vessels elsewhere. [2] The tit-for-tat attacks have continued since the start of the war with at least 75 ships attacked and at least 21 seafarers killed. [2] Two incidents resulted in minor oil spills while six caused fires. [2]

Environmental risks mount from oil spills

As of September 7 MarineTraffic data showed 42 tankers waiting to transit the Strait of Hormuz with 18 carrying oil and an estimated combined capacity of 1.76 million cubic metres of oil and petroleum products. [2] That volume equals roughly 11.1 million barrels. [2] A spill already spreading off Oman has been leaking from the Caroline Bezengi since it ran aground about 22 nautical miles off Oman after its crew reported a suspected explosion in early June. [2] Reuters estimates the tanker was carrying 800000 barrels of oil. [2] Oman’s Environment Authority warned that the spill could affect about 40km of coastline near Ras Madraka as well as Masirah Island. [2] On August 3 the Minoan Pioneer a Liberian-flagged bulk carrier was struck by an unidentified projectile off Oman and caught fire. [2] Satellite imagery taken on August 10 showed a large slick near Qeshm Island while another slick was detected near Sirri Island. [2] Past conflicts like Operation Desert Storm left a legacy of environmental pollution when Iraqi forces set Kuwaiti oil wells on fire releasing millions of gallons of oil into the northern Gulf coast. [2] Over 770km of coastline from southern Kuwait to Abu Ali Island in Saudi Arabia were engulfed in oil and tar wiping out local marine ecosystems. [2] The Gulf contains resilient coral reefs and mangrove forests that survive in one of the world’s hottest and most saline marine environments. [2] Oil spills lay on top of the water damage and poison marine life pollute the water and smother coral reefs and mangroves. [2] The Gulf countries primarily rely on desalination as the primary source of water for the entirety of its nearly 65 million population. [2]

Oil prices surge toward $100 barrel

Oil prices jumped more than one percent toward $100 Wednesday with Brent hitting as high as $99.68. [3] West Texas Intermediate was heading toward $95 for the first time since June. [3] The surge in energy costs has kept inflation elevated globally and is putting pressure on central banks to hike borrowing costs. [3] Tehran maintains a stranglehold on the Strait of Hormuz a vital shipping route for the world’s oil and gas. [3] Saudi Arabia and Iran-backed Houthis in Yemen exchanged strikes with the rebels targeting oil facilities in an offensive toward the Red Sea’s Bab al-Mandab chokepoint. [3]

South Korea assesses possible Hormuz role

South Korea’s Defense Ministry sent personnel to the UAE to evaluate regional security conditions for potential contributions such as P-8A Poseidon aircraft explosive ordnance disposal teams or uncrewed mine systems. [1] The assessment came after the Defense Ministry confirmed that a team had traveled to the UAE over the weekend to examine security conditions and operational circumstances around the strait. [4] US President Donald Trump has urged Seoul to contribute more to Hormuz operations. [1] Among the options reportedly under consideration are P-8A Poseidon maritime patrol aircraft explosive ordnance disposal personnel and uncrewed mine-detection and clearance systems. [4] The Navy’s Soyang-class logistics support ship had also been considered although its large crew requirement and age have reportedly lowered its priority. [4] Seoul has stressed that no decision has been made on contributing troops or military assets. [1]

Political and procedural hurdles in Seoul

Any deployment would require National Security Council review Cabinet deliberation and National Assembly approval. [1] President Lee Jae Myung said any South Korean contribution to Strait of Hormuz security would be shaped by national interests and public consensus while supporting global supply-chain stability. [1] Resistance has already emerged even within the ruling camp with several Democratic Party of Korea lawmakers arguing that even sending noncombat forces to Hormuz could amount to participation in the US war against Iran. [4] Members of South Korean civic groups held up signs during a protest against the deployment of South Korean troops to the Strait of Hormuz in Daejeon on Monday. [4] Iran’s warning of serious consequences further complicates the government’s calculations. [1] President Lee Jae Myung and French President Emmanuel Macron discussed freedom of navigation and regional stability but Seoul said their summit should not be interpreted as talks on troop deployment. [1]

Strategic considerations for South Korea

The UAE is geographically close to the Strait of Hormuz and has relatively well-developed military and logistics support infrastructure. [4] The country could serve as a rear-area base for noncombat or defensive missions such as maritime surveillance navigation safety explosive ordnance disposal and logistics support rather than placing South Korean forces directly on the front line. [4] A P-8A could support wide-area maritime surveillance while EOD personnel and unmanned systems could respond to mines and other explosive threats. [4] The Cheonghae Unit has operated in waters off the Middle East since 2009 primarily conducting antipiracy missions and protecting commercial vessels. [4] A deployment could benefit ties with Washington but cautioned against expecting it to resolve the broader issues between the two countries. [4] At a time when the United States could hold talks with North Korea and South Korea could be sidelined the government may be trying to restore its relationship with Washington through a deployment. [4]

What to watch next: Seoul continues to weigh its options after the UAE assessment while the National Assembly consent process and any further US requests remain key factors in whether a contribution moves forward.
