When a rogue actor threatens to turn an international waterway into a private toll booth, every trading nation on Earth ought to pay attention. That was the central message delivered by US Secretary of State Marco Rubio in Manila on July 22, 2026, as he addressed foreign ministers at the Association of Southeast Asian Nations meeting.
Iran’s demand to control commercial maritime traffic through the Strait of Hormuz and slap tolls on passing vessels isn't just a Middle Eastern crisis. It sets an alarming precedent that could easily spill over into the Indo-Pacific and beyond.
If Tehran gets away with forcing ships to pay up or risk missile strikes, the foundational rules of international ocean transit break down. For Southeast Asian economies already reeling from energy price spikes, the threat couldn't be more direct.
Here's why Washington is pressing regional allies to take a hard stand, what it means for global supply chains, and why the fallout extends far past the Persian Gulf.
What Iran Demands in the Strait of Hormuz and Why It Threatens Global Trade
The Strait of Hormuz is barely 21 miles wide at its narrowest point, yet roughly a fifth of the world’s petroleum passes through it. Under long-established international maritime law—specifically the United Nations Convention on the Law of the Sea—international straits afford foreign ships the right of transit passage without interference, fees, or political extortion.
Tehran is trying to throw those rules out the window.
In recent months, Iranian forces have intensified attempts to claim sovereign authority over the strait, demanding tariffs from merchant vessels and threatening violent escalation against anyone who refuses to comply. Rubio didn't pull any punches when describing the stakes to Southeast Asian leaders in Manila.
"If we create a precedent in the Middle East where a nation-state can decide that they are going to control an international waterway, charge a toll and if you don't pay them, blow up your ships, we have created a very dangerous precedent which will repeat itself in other parts of the world, including in this region," Rubio warned.
The US Secretary of State made it clear that allowing state-sanctioned piracy under the guise of local jurisdiction completely dismantles international freedom of navigation. If a nation can unilaterally blockade or tax a global chokepoint without consequence, the rule of law at sea effectively ceases to exist.
The South China Sea Connection Asian Nations Cannot Ignore
Rubio's warnings were tailored specifically for his audience in Manila. Southeast Asian capitals understand maritime bullying all too well.
China has spent years asserting illegal territorial claims over nearly the entire South China Sea, constructing militarized artificial islands, water-cannoning Philippine supply boats, and harassing regional fishermen. Smaller nations like the Philippines, Vietnam, Malaysia, and Brunei have fought constantly to preserve their legal rights under international law.
Imagine Beijing deciding tomorrow that commercial vessels sailing through the South China Sea owe tariff payments to the Chinese navy.
If Iran successfully normalizes toll collection and maritime threats in the Persian Gulf, it hands Beijing a ready-made playbook. Authoritarian regimes across the globe are watching how the international community responds to Tehran. If the response is weak, expect similar extortion schemes to pop up in the Malacca Strait, the Bab-el-Mandeb, or the Taiwan Strait.
To reinforce American commitment to regional stability, Rubio assured ASEAN representatives that despite Washington's heavy focus on Middle Eastern conflict, the United States remains "with ASEAN 100%".
Energy Vulnerability in Asia as Crude Imports Take a Direct Hit
Beyond the legal standard, Asian economies have a brutal financial reason to care about Hormuz. They are the primary buyers of oil and gas moving through the choke point.
According to data from the International Energy Agency, Asian markets imported roughly 80% of the crude oil and nearly 90% of the liquefied natural gas passing through the Strait of Hormuz. Southeast Asian nations don't have deep strategic petroleum reserves to ride out months of severe maritime blockades.

When tankers face extortion or missile attacks in the Middle East, insurance premiums for commercial freight rocket sky-high almost overnight. Shipping lines re-route vessels around Africa's Cape of Good Hope, adding weeks to transit times and burning thousands of additional tons of fuel.
The end result? Higher fuel prices at the pump in Manila, elevated electricity bills in Tokyo, and compounding inflation across Asian manufacturing hubs. The IEA called the ongoing disruption a "stark wake-up call" for regional energy security. Southeast Asian leaders aren't just observing a diplomatic squabble; they are watching their own domestic inflation numbers get dictated by Iranian missile batteries.
Strategic Side Meetings and Diplomacy in Manila
The annual diplomatic gathering in the Philippines wasn't limited to general ASEAN assembly talks. High-stakes bilateral discussions occurred on the sidelines in a tightly secured convention complex overlooking Manila Bay.
The Quad Diplomatic Coalition
Foreign affairs ministers from the Quad framework—the United States, Australia, India, and Japan—met to reaffirm their commitment to Indo-Pacific security. They issued a joint statement underscoring that peace and stability in maritime domains remain essential for global prosperity. Rubio later posted on X that "The Quad remains a priority, and we will meet again later this year".
US-India Trade Talks
Rubio met directly with Indian External Affairs Minister Subrahmanyam Jaishankar. Alongside energy disruptions caused by the Iran conflict, the two diplomats focused heavily on finalizing an interim trade agreement designed to lower tariffs on Indian goods entering the US. US State Department spokesperson Tommy Pigott confirmed that both sides agreed the deal is nearly complete.
Dialogue with Beijing and Moscow
The Manila summit also brought together foreign ministers from competing powers, including Chinese Foreign Minister Wang Yi and Russian Foreign Minister Sergey Lavrov.
Lavrov indicated to reporters that Moscow wants to see a swift resolution between Washington and Tehran, citing global energy volatility. Russia is interested in stable energy markets to maintain its long-term economic planning. Rubio was scheduled to meet separately with Lavrov to explore potential diplomatic avenues regarding the war in Ukraine, as well as holding direct talks with China's Wang Yi.
How Maritime Security and Global Freight Realities Will Unfold Next
Talk in conference halls won't secure commercial shipping lanes by itself. If you're managing global supply chains or evaluating geopolitical risk, here are the real-world operational steps to take right now:
- Diversify Middle Eastern Energy Reliance: Asian energy importers must immediately accelerate long-term supply contracts with West African, North American, and Australian exporters to reduce single-point vulnerability in the Persian Gulf.
- Account for War-Risk Freight Surcharges: Logistics managers should budget for elevated war-risk insurance premiums and potential rerouting fees through the remainder of 2026.
- Monitor Maritime Security Alliances: Watch naval deployment commitments from Quad members and ASEAN allies closely. Enhanced joint patrols in crucial waterways serve as the only effective physical deterrent against unlawful toll demands and ship seizures.
International shipping rights aren't self-enforcing. If democratic nations fail to protect open seas in the Middle East, they will soon find themselves paying tolls in their own backyards.
