US-Iran Conflict: Widening Threat to Regional Stability, Global Energy and Trade

Why in News? 

Renewed U.S.-Iran attacks on tankers and military installations, alongside Houthi attacks on Saudi Arabia, have widened the conflict across West Asia. The simultaneous threats to Hormuz and Red Sea shipping are increasing energy prices and exposing the region’s economic and security vulnerabilities.

Location and geographical importance of Hormuz: 

• Location: The strait lies between Iran to the north and Oman’s Musandam Peninsula to the south; the UAE lies nearby on its southern approaches.
• Connectivity: It connects the Persian Gulf with the Gulf of Oman, which opens into the Arabian Sea.
• Narrow passage: It is approximately 33-34 km wide at its narrowest point. Commercial traffic uses considerably narrower designated shipping lanes, increasing vulnerability to disruption.

Why is Hormuz difficult to replace in global energy trade?

• Large oil flows: In the first half of 2025, approximately 20.9 million barrels per day passed through Hormuz, around 20% of global petroleum-liquids consumption and one-quarter of global seaborne oil trade.
• Critical LNG route: Over 20% of global LNG trade, primarily from Qatar, passed through it during the same period. 
• High Asian exposure: About 89% of crude oil and condensate flows through Hormuz went to Asian markets; China, India, Japan and South Korea together accounted for 74%.
• Limited bypass capacity: Saudi Arabia and the UAE possess major bypass pipelines. Iran also has the Goreh-Jask route, but with limited effective capacity. These alternatives cannot replace all flows through Hormuz. 

What is happening in the Strait?

The latest escalation has opened a new maritime front in the U.S.-Iran confrontation.

• The United States has struck Iranian oil tankers, claiming that the action was in response to attacks on U.S. naval assets.
• Iran has responded by targeting vessels attempting to transit the Strait and declaring additional maritime areas as restricted or prohibited zones.
• Iran’s actions are aimed partly at challenging the U.S. naval blockade and restrictions on Iranian oil exports.
• The confrontation has therefore moved beyond attacks on military targets to include commercial shipping and energy infrastructure, increasing the risk of wider regional escalation.

Why is this particularly dangerous?

• Spillover into Neighbouring states: Iranian attacks on a U.S. base in Jordan demonstrate how countries hosting foreign military installations can become exposed.
• Renewed Saudi-Houthi hostilities: Houthi missile and drone attacks have struck Saudi energy and economic facilities, while fighting has intensified along Yemen’s western coast. Saudi authorities reported 73 injuries in the recent attacks. 

The conflict is no longer confined to one theatre. The involvement of Jordan, Saudi Arabia, Yemen and the Red Sea creates the possibility of horizontal escalation across multiple maritime and land fronts.

The simultaneous vulnerability of Hormuz and the Red Sea-Bab el-Mandeb corridor could disrupt both Gulf energy supplies and the Europe-Asia trade route. 

What are the wider regional implications?

• Pressure on two strategic maritime passages: Hormuz insecurity affects access to the Persian Gulf, while Houthi operations threaten the Bab-el-Mandeb-Red Sea route. Houthi advances towards Mocha and nearby coastal areas could strengthen their ability to disrupt shipping.
• A security dilemma for Gulf monarchies: Gulf states must protect infrastructure and maintain defence partnerships while avoiding deeper involvement in the war. Foreign military presence may strengthen deterrence but also create potential targets, complicating efforts to remain outside hostilities.
• Threat to economic diversification: Tourism, aviation, logistics, financial services and major investment projects depend on confidence and predictability. Prolonged insecurity can raise financing costs, delay investment and undermine plans such as Saudi Vision 2030.
• Renewed instability in Yemen: Escalating Saudi-Houthi confrontation threatens the gains from earlier de-escalation and aggravates displacement, food insecurity and pressure on humanitarian services. Yemen’s conflict is increasingly intertwined with regional maritime competition.
• Food, water and electricity insecurity: Gulf economies depend heavily on maritime imports and interconnected energy infrastructure. Disruption can affect food availability, fuel supplies and essential services. Damage to power or desalination systems would have particularly serious civilian consequences.
• Strain on regional diplomacy: Retaliatory attacks can weaken confidence-building between Iran and Arab neighbours. Mediators face the difficult task of separating immediate navigation and humanitarian agreements from larger disputes over sanctions, military presence and regional influence.
• Greater influence of armed non-state actors: Relatively inexpensive missiles and drones can impose substantial costs on shipping and infrastructure. This gives groups such as the Houthis leverage beyond their economic size and complicates conventional deterrence.
• Environmental and coastal damage: Tanker attacks create risks of oil spills, toxic smoke and damage to fisheries, mangroves and coastal livelihoods. Pollution may also threaten seawater intakes serving desalination facilities.

The widening conflict shows that maritime security, regional prosperity and civilian welfare are closely connected. Restoring dependable navigation and preventing further spillover are essential to both regional stability and global economic security.
