US-Iran Tensions Drive Oil Prices Higher, Threatening Global Energy Security
July 17, 2026 - Escalating confrontations between the United States and Iran, attacks on critical infrastructure, and near-complete cessation of oil tanker traffic through the Strait of Hormuz are fueling predictions of even higher oil prices in the coming months.
The US military's attack on civilian infrastructure in Iran, Tehran's retaliatory strikes on power desalination plants in Kuwait, along with repeated attacks on oil tankers in the Strait of Hormuz and the potential expansion of maritime warfare to the Bab el-Mandeb Strait—all point toward a continued upward trend in oil prices. With tanker traffic through Hormuz reduced to nearly zero, ICE Brent trading around $86 per barrel seems counterintuitive, especially as both Washington and Tehran appear to have abandoned diplomatic channels.
Impact on Major Oil Importing Countries
China, the world's largest oil importer, has seen its crude oil purchases drop 41% compared to the same period in 2020 to 7.12 million barrels per day, the lowest level since October 2016. This decline is attributed to Gulf War disruptions to Middle Eastern supply and weakening domestic demand.
The US Department of Defense has redirected two commercial vessels since reimposing the blockade of Iranian ports, reviving an enforcement operation that has intercepted 140 vessels and disabled 9 others between April and June, yet has been unable to completely halt Iran's crude oil exports.
| Country | Primary Impact | Countermeasures |
|---|---|---|
| China | 41% decrease in oil imports year-on-year | Reduced purchases due to weak domestic demand and supply disruptions |
| India | 2 citizens killed in attacks | Banned deployment of seafarers through the Strait of Hormuz |
| Pakistan | Risk of natural gas liquefied (LNG) shortages | Paying premium prices of $20.7/MMBtu for emergency LNG |
The International Energy Agency (IEA) has warned that the global economy could face severe difficulties if the Strait of Hormuz is not fully reopened within the next few weeks. IEA Director Fatih Birol noted that disrupted flows of oil, gas, and fertilizer are most threatening to import-dependent economies like Pakistan and India.
Security and Energy Crisis
Iraq has suspended crude oil exports after a suspected drone approached a tanker vessel in Basra, though operations have since resumed without reports of damage. Meanwhile, security threats have forced the Khor Mor gas field to suspend operations, cutting 2.5 GW from the electricity supply in Kurdistan.
The hacker group World Leaks has published 19,000 files allegedly related to the Kudankulam nuclear plant, including facility plans and supplier information, though the plant operator confirmed that the leak only concerned routine services, not security or nuclear safety systems.
Changes in Energy Trade
New Delhi has nearly doubled export duties on diesel and jet fuel to 15.5 and 14.5 rupees per liter respectively, aiming to protect domestic supplies as robust profit margins pushed shipments from Asia's largest fuel exporter to their highest levels since September.
The first US LNG tanker to arrive at a Chinese port since February 2025 has reached Hainan, but its storage tank status means the fuel could be stored, traded, or re-exported without customs clearance, as Beijing's 15% tariff makes direct importation uneconomical.
Russia's leading oil companies have approached Indian refineries about gasoline and diesel after Ukrainian attacks disabled a significant portion of domestic refining capacity, reversing the typical energy trade relationship between the two countries, with up to 40% of Russian capacity potentially offline in July-August.
Impact on Other Industries
Nickel has risen to a three-week high of over $17,000 per ton as disrupted sulfur shipping from the Gulf threatens production in Indonesia, the world's largest nickel producer, with 75% of their sulfur coming from the region and processing costs increasing by $10,000 per ton.
US oil giant ConocoPhillips will acquire a 42% stake in BP's northern Iraq project, collaborating to develop 4 producing fields containing over 3 billion barrels of resources as Baghdad seeks to counter China's growing dominance with greater American investment.
Tasmania's Liberty Bell Bay manganese smelter will shut down immediately after administrators failed to find a commercially viable buyer, despite federal and state support including $10 million for wages, a $20 million restart package, and discounted power supply.
Somali piracy suspects have boarded and taken control of the chemical tanker Asana in the Gulf of Aden, marking the region's recent resurgence in piracy, as Iran has requested Yemen's Houthi fighters to be ready to blockade the Bab el-Mandeb Strait if the US attacks Tehran again.
Conclusion
The escalating geopolitical tensions between the United States and Iran are creating an unprecedented energy crisis with far-reaching consequences for the oil market, energy trade, and dependent industries. The near-complete cessation of tanker traffic through the Strait of Hormuz, along with threats expanding to other maritime routes, raises serious questions about global energy security in the coming weeks.
In this context, countries and companies are facing difficult choices—from paying higher prices for energy, seeking alternative supplies, to implementing export controls to protect domestic supplies. The future of the global energy market depends heavily on whether US-Iran tensions can be de-escalated.
