# Iran Resumes Missile Attacks on US Assets, Closes Strait of Hormuz; Brent Crude Spikes 3.1%

*Renewed hostilities reverse earlier US-Iran ceasefire, disrupt global energy supplies, push Brent crude to $84.58 per barrel*

## Why this matters

The Strait of Hormuz closure and US-Iran escalation directly impact India's energy security and West Asia policy. Brent crude spikes threaten India's inflation and current account deficit.

## In plain words

Imagine a narrow mountain pass that every oil tanker from the Gulf must cross to reach the world. That pass is the Strait of Hormuz. When Iran and the United States start firing missiles near it, the pass becomes dangerous, so ships stop or reroute, and the price of oil everywhere jumps. This story is about that exact moment in July 2026.

Iran launched ballistic missiles at US forces in the Middle East, but all were intercepted by US defenses. In response, the US and Saudi Arabia struck Iran-backed militia sites in eastern Iraq. Just before this, Iran had effectively closed the Strait of Hormuz by firing at or threatening tankers, demanding ships use a route near its coast. This choked off a waterway through which about one-fifth of the world's traded oil normally flows, pushing Brent crude up 3.1% to $84.58 per barrel.

Think of the strait like a single bridge connecting a factory to its market. If the bridge is blocked, the factory's goods cannot reach buyers, and prices rise everywhere. Here, the 'bridge' is the strait, and the 'goods' are oil. The US now escorts ships along Oman's coast, while Iran's Houthi allies in Yemen block the Bab el-Mandeb route, creating a double squeeze on global energy.

## Key facts

- Iran resumed attacks after collapse of interim US-Iran deal, effectively closed Strait of Hormuz (crucial global energy waterway)
- US and Saudi forces struck Iran-aligned Iraqi militias in response to renewed missile attacks
- Brent crude jumped 3.1% to $84.58 per barrel amid supply disruption fears
- Mediators continue closed-door diplomacy to restore ceasefire, no progress reported yet
- Flare-up raises risk of all-out war, jolts world economy already strained by five-month conflict

## How we got here

The current conflict began on 28 February 2026, when Iran initiated hostilities that led to the effective closure of the Strait of Hormuz. Before this, the strait had been a relatively stable, though tense, transit point for roughly one-fifth of the world's traded oil and gas. An interim ceasefire deal was signed in June 2026, briefly pausing the fighting. However, a battle for control over the strait erupted immediately after the deal. Iran claims sovereign authority over the waterway and the right to designate approved transit routes, a position rejected by the US, Gulf states, and most of the international community under the UN Convention on the Law of the Sea (UNCLOS), which Iran has signed but never ratified. The US, under CENTCOM, has redirected commercial vessels and enforced maritime restrictions, while Iran's IRGC has intercepted vessels attempting unauthorized transit. This latest flare-up follows a month of pressure on the US administration, including the deaths of four US troops and congressional skepticism over funding.

## The bigger picture

**International — US-Iran-Saudi Trilateral Military Dynamics**

The US and Saudi Arabia conducted joint strikes on Iran-backed militia logistics sites in eastern Iraq, responding to over 30 IRGC-directed drone attacks in 72 hours. This marks a direct Saudi entry into active combat alongside US forces, moving beyond its traditional defensive posture. Iran, meanwhile, uses proxy groups like the Houthis in Yemen and the Islamic Resistance in Iraq to exert pressure, creating a multi-front conflict. The US maintains it does not seek escalation but will protect its forces and Saudi infrastructure, as stated by CENTCOM.

→ Saudi Arabia's active combat role alongside the US signals a shift in regional security architecture.

**Economic — Global Energy Supply and Inflationary Pressure**

The Strait of Hormuz closure has disrupted the flow of 20% of the world's traded oil, causing Brent crude to spike 3.1% to $84.58 per barrel. This is compounded by Houthi blockades in the Bab el-Mandeb strait, affecting Red Sea shipping. High gasoline prices in the US are already influencing domestic politics ahead of midterm elections, with the House passing a resolution to halt military action. For import-dependent economies like India, such spikes threaten inflation and current account stability.

→ Chokepoint disruptions create immediate global oil price volatility with cascading macroeconomic effects.

**Political — Diplomatic Stalemate and Domestic Pressures**

Despite mediators achieving progress, officials report no breakthrough in restoring the ceasefire, with Iran stating 'the timing of war and peace is not yours to decide.' Domestically, the US faces political heat as the war's unpopularity grows, reflected in a House resolution against military action. Iraq is caught in the middle, with Prime Minister Ali al-Zaidi ordering investigations into militia activities to prevent Iraqi territory from being used for attacks, emphasizing commitment to regional stability.

→ Diplomatic efforts are stalled by mutual distrust and significant domestic political constraints in the US.

**Other angle — Strategic Chokepoints: Hormuz and Bab el-Mandeb**

The Strait of Hormuz, a narrow waterway between Oman and Iran, is the primary exit for Persian Gulf oil. Iran's closure forced ships to a southern route along Oman under US escort. Simultaneously, Houthi rebels in Yemen have targeted the Bab el-Mandeb strait, the gateway to the Red Sea and Suez Canal. Control over these two chokepoints allows Iran and its proxies to exert leverage over global maritime trade routes, as seen with the tanker NCC Ghazal being forced to turn back.

→ Dual threats to Hormuz and Bab el-Mandeb create a pincer movement on global energy transit.

## The big debate

**Is the US military response to Iran-backed militia attacks a necessary defense of regional stability or a dangerous escalation?**

**For**
- Protecting energy infrastructure and freedom of navigation in Hormuz is vital for the global economy and US strategic interests.
- Deterring IRGC-directed attacks prevents further loss of American lives and reassures regional allies like Saudi Arabia.

**Against**
- Military strikes risk a full-scale regional war with Iran, drawing in more actors and destabilizing the Middle East further.
- Such actions may be driven by domestic political cycles rather than long-term strategic goals, as seen in US midterm concerns.

**The balanced take:** While defending against immediate threats is justified, the lack of a clear diplomatic off-ramp and the use of proxies make the situation volatile. A sustainable solution requires coupling defensive measures with renewed, unconditional negotiations to address the root causes of the conflict.

## What should happen

1. **Immediate restoration of the June 2026 interim ceasefire with expanded monitoring.** A verified pause in hostilities is essential to de-escalate and allow diplomatic space.
2. **Establishment of a UN-led maritime security corridor under UNCLOS provisions.** Neutral oversight can reduce unilateral claims over the Strait of Hormuz. *(UNCLOS)*
3. **Inclusive regional dialogue involving Iran, Saudi Arabia, Iraq, and the US.** Addressing proxy networks requires direct communication between regional rivals.
4. **Diversification of global energy supply routes to reduce chokepoint vulnerability.** Reducing reliance on Hormuz and Bab el-Mandeb enhances long-term energy security. *(SDG 7)*
