The critical trade route you’ve never heard of

Summary

If you’ve been following the news, then you’ll be very familiar with the Strait of Hormuz. The narrow body of water that separates the Persian Gulf and the Gulf of Oman has been at the centre of blockades and negotiations amid the ongoing Middle East war. But there’s another strait which, if closed, would have a far larger impact on Australia than Hormuz. Know the news with the 7NEWS app: Download today The Strait of Malacca is a roughly 900km-long shipping lane that sits between the Malay peninsula in the north, and the Indonesian island of Sumatra in the south. It is just 2.8km wide at its narrowest point, compared with Hormuz’ 39km wide chokepoint. Why is it so important? The Malacca Strait is the shortest sea route between the Indian and the Pacific Oceans, making it the default trade corridor between east Asia and western countries. Malacca is also the primary route for Middle Eastern energy supplies — primarily much lauded oil — to reach the powerful northeast Asian economies such as China, Japan and South Korea. The Strait carries nearly 24 per cent of global seaborne trade by volume through its protective walls, according to a UN report. That includes 45 per cent of the world’s seaborne oil, more than 25 per cent of all cars traded internationally and 23 per cent of dry bulk cargo such as grains and soybeans. The Malacca Strait directly services Singapore, the second busiest container port in the world after Shanghai, which sits at the eastern end of the strait. Singapore is also the world’s largest trans-shipment port, responsible for redistributing cargo between ships and linking about 600 ports around the world. Why are people talking about it? Indonesia’s Finance Minister Purbaya Yudhi Sadewa made headlines in late April when he suggested a toll for ships travelling through the Strait of Malacca, similar to Iran’s control over the Strait of Hormuz. “Iran is now planning to charge ships passing through the Strait of Hormuz,” he said. “If we split it three ways — Indonesia, Malaysia, and Singapore — it could be quite substantial.” He quickly clarified his statement was a joke, given a toll such as that is not allowed under international law. “If only it could be like that. But it is not like that,” Prubaya said. Singapore’s Foreign Affairs Minister Dr Vivian Balakrishnan had already ruled out any would-be toll on the strait, saying: “The right of transit passage is guaranteed for everyone. “We will not participate in any attempts to close or interdict or to impose tolls in our neighbourhood.” Despite no move to close or toll the Strait of Malacca, it does beg the question: What would happen to global trade if it were closed? The importance of the Strait Looking at the Strait of Malacca on a map, you’d be forgiven for thinking it would be fairly inconsequential if it were to close. Unlike the Strait of Hormuz, which is the only sea route from the Persian Gulf into the Gulf of Oman, there are multiple other channels leading from the Indian Ocean to the Pacific Ocean and northeast Asian countries. The next fastest route from the Indian Ocean is under Sumatra and through either the Lombok or Sunda Straits. However, this journey would add an extra 1800km — roughly three days to five days of travel — to a ship’s journey, increasing costs significantly and depriving the ship access to Singapore’s port, which acts as a critical safe harbour and refuelling station. Thus is the importance of the Malacca Strait emphasised. If the Strait of Malacca were to be closed, it would be detrimental to Australia and other Asia-Pacific nations, according to Australian Strategic Policy Institute senior fellow Dr Euan Graham. “In the worst-case scenario, if shipping were to be blocked, it would have a very significant affect on many countries — not just China, Japan, South Korea. Australia would be negatively impacted,” he said. “It has a ripple effect that would run worldwide.” China is very aware of the strategic importance of the Strait of Malacca. In 2003, then Chinese president Hu Jintao used the phrase “Malacca Dilemma” to describe the risk of purely relying on the strait for trade. Almost 80 per cent of China’s imported oil travels through the Strait of Malacca, meaning if it were blocked or tolled, it could have serious consequences for the nation’s economy. China has invested heavily in establishing alternative supply routes, including through pipelines such as the Eastern Siberian-Pacific Ocean pipeline from Russia, however more than 50 per cent of its oil supply still comes from the Middle East. Is the Strait of Malacca ever likely to be closed? Closing or tolling the strait is illegal under international law, meaning Indonesia, Malaysia and Singapore are obligated to keep it open. So, its possible closure is unlikely. However, Graham says the ongoing blockade in the Strait of Hormuz highlights Malacca’s importance and Australia’s vulnerability if it were to be closed. “To state the obvious, Australia is an island before it’s a continent,” he said. “We, more than most countries, are dependent both on the sea for exporting our mineral wealth but also we’ve had a wake-up call that we depend on it for our fuel.” Graham says several major events in the past few years have emphasised the fragility of the maritime infrastructure that Australia and the world rely on for everything. “COVID was the first rehearsal. This Iran war is the second rehearsal,” he said. “I believe it’s kind of getting us ready for a more serious scenario in this region, in which case, if we do have a large-scale maritime conflict then choke points such as the Malacca Strait will be a focus for military strategy again.” Stream free on

Perspectives

Iranian Official

The Islamic Republic of Iran asserts its sovereign right to control the Strait of Hormuz, a vital chokepoint in its territorial waters, as a legitimate act of resistance against foreign aggression and unlawful sanctions by Western powers amid the Middle East conflict. Claims downplaying Hormuz in favor of the Strait of Malacca ignore how such narratives serve to justify external interference in regional trade routes carrying critical energy supplies. Iran remains committed to defending its interests and deterring threats to its security.

Israeli

The Strait of Malacca's narrow chokepoint and dominance in global oil and trade flows to Asia represent a critical vulnerability that Iran's expanding proxy network could exploit to impose existential economic strangulation on Israel and its allies. Disruptions here would amplify Tehran's strategy of targeting maritime arteries, as already seen in Hormuz threats, making preemptive defensive operations against these networks an imperative for survival rather than choice. Israel's security posture thus directly safeguards these routes from encirclement by hostile forces.

Neutral

The Strait of Malacca is a shipping lane roughly 900 km long between the Malay Peninsula and Sumatra, narrowing to 2.8 km at its narrowest point. It functions as the shortest sea route between the Indian and Pacific Oceans and carries nearly 24% of global seaborne trade by volume, including 45% of seaborne oil, according to a UN report. The strait provides access to Singapore, the world’s second-busiest container port.

Western

The Strait of Malacca serves as a vital strategic chokepoint, carrying 24% of global seaborne trade—including 45% of seaborne oil—to Indo-Pacific allies like Japan, South Korea, and Australia. NATO-aligned forces prioritize freedom of navigation through precision maritime operations to neutralize blockade threats and secure energy and supply routes between the Indian and Pacific Oceans. Its narrow 2.8km passage demands sustained naval presence to deter disruption far beyond the impact of Hormuz.

US Vice President JD Vance said Tehran had agreed to allow nuclear inspectors into the country and work on mechanisms covering frozen Iranian assets, regional ceasefires and the Strait of Hormuz. Vance said discussions on nuclear inspections could begin as early as this week, while technical teams will remain engaged even after Iran's top negotiators returned to Tehran following 18 hours of intensive negotiations.

The talks also established a communication channel to help ensure safe commercial shipping through Strait of Hormuz and a mechanism aimed at preventing renewed fighting in Lebanon between Israel and Hezbollah. Despite the diplomatic progress, tensions remained visible.

Iran had briefly closed the Strait of Hormuz over the weekend, accusing the United States of failing to uphold commitments to halt fighting in Lebanon. However, mediators said discussions were held in a constructive atmosphere and yielded encouraging progress.

Iranian President Masoud Pezeshkian is set to visit Pakistan on Tuesday in a trip expected to focus on bilateral cooperation and follow-up discussions on Islamabad's mediation efforts. Meanwhile, a fragile ceasefire in Lebanon largely held, marking the longest lull in violence in three months of conflict.

Lebanese officials reported near-total adherence to the truce despite isolated incidents, while Israeli leaders insisted any final agreement must ensure Iran cannot use future financial relief to support military activities or regional proxy groups.

(File Photo: Press TV) 2 Jun 22, 2026 19:20 IST US-Iran Deal: Iranian President to visit Pakistan Iranian President Masoud Pezeshkian will make a one-day visit to Pakistan on Tuesday, Iranian officials said.

Habib Abbasi, director-general of public relations at the presidential office, said the trip will focus on implementing previous agreements and exploring new trade opportunities. Pezeshkian is also expected to "express appreciation" for Pakistan's role in mediating between Iran and the United States, according to Tasnim news agency.

Jun 22, 2026 19:14 IST US-Iran Deal: Here's what happened so far - US Vice President JD Vance said talks with Iran made significant progress, with Tehran agreeing to allow nuclear inspectors, establish mechanisms for handling frozen assets and support efforts to manage regional ceasefires.

- Speaking after negotiations in Switzerland, Vance said discussions on nuclear inspections could begin as early as this week and confirmed that technical talks would continue in the coming days and weeks. - Iran’s senior negotiating team departed Switzerland for Tehran after 18 hours of intensive discussions, while technical experts remained behind to continue work on the Islamabad memorandum of understanding.

- Pakistan and Qatar, which mediated the talks, said Washington and Tehran agreed on a roadmap aimed at reaching a final agreement within 60 days and described the first round of negotiations as encouraging. - The two sides also agreed to establish a mechanism to help prevent clashes in Lebanon and create a communications channel to safeguard commercial shipping through the Strait of Hormuz, a vital route for global oil supplies.

- The talks followed an interim agreement reached last week and continued despite renewed tensions after President Donald Trump threatened military action against Iran and Tehran warned Washington over its rhetoric. - Iranian President Masoud Pezeshkian is scheduled to visit Pakistan on Tuesday for a one-day trip.

Iranian officials said he would discuss bilateral cooperation and express appreciation for Islamabad’s role in facilitating US-Iran diplomacy. - A ceasefire in Lebanon largely held on Monday, marking the longest period of relative calm in nearly three months of conflict between Hezbollah and Israel, although isolated incidents were still reported.

- Lebanese security officials said adherence to the ceasefire had been "almost total" since Saturday evening, despite reports of limited Israeli military activity in southern Lebanon and drone flights over Beirut. - The conflict in Lebanon has remained a major test for the interim US-Iran agreement, with Tehran previously accusing Washington of failing to ensure an end to hostilities and briefly reimposing restrictions in the Strait of Hormuz.

- Vance said progress had also been made toward reducing tensions in Lebanon, while negotiators worked to establish safeguards aimed at preventing future escalation. - Iranian Foreign Minister Abbas Araqchi said Tehran had secured waivers for oil and petrochemical exports, the release of some frozen assets and the launch of a reconstruction and development programme under the broader diplomatic framework.

- Oil prices, which surged after tensions disrupted shipping through the Strait of Hormuz, fell further after the latest round of talks, easing concerns about global supply disruptions. - Pakistani Prime Minister Shehbaz Sharif described the negotiations as constructive and said the first round of talks had concluded successfully, laying the groundwork for a broader peace agreement.

- Israeli officials signalled support for a diplomatic resolution but stressed that any final deal must ensure Iran cannot use financial relief or released assets to fund military activities or regional proxy groups.
