From Trump’s
Sanctions Threat to a Possible Opening of Hormuz
- Last week, U.S. President Donald Trump threatened Iran with what could have amounted to an economic bombshell: what he called the “toughest ever sanctions” on Tehran. The deadline came and went. Some measures were announced, but the sweeping sanctions many expected never materialized.
- Now, the focus has shifted from sanctions to diplomacy—and from Washington to the "Strait of Hormuz."
- Oil prices fell to a one-week low as markets responded to fresh hopes that the strategically vital waterway could reopen. Iran and Oman have held talks, with the two countries' foreign ministers meeting in Tehran to discuss a possible temporary arrangement for restoring shipping through the strait.
- The development matters far beyond the Middle East. The Strait of Hormuz is one of the world's most important energy chokepoints, and any sustained disruption can quickly translate into higher oil prices, supply-chain pressure, and wider economic uncertainty.
Oman: The
Mediator Caught in the Middle
- Oman's role in the crisis is particularly important.
- For years, Oman has served as a key mediator between Washington and Tehran, maintaining a diplomatic back channel between the United States and Iran. But this month, Oman itself came under pressure.
- Trump threatened to bomb Oman if it helped Iran in connection with the Strait of Hormuz. The warning represented a dramatic escalation in rhetoric toward a country that has traditionally played a mediating role in regional diplomacy.
- Now, however, that confrontation appears to have receded. Oman's foreign minister has travelled to Tehran and discussed a temporary mechanism for reopening the Strait of Hormuz. The precise details are still being negotiated, and ran and Oman has since announced a framework for a temporary maritime corridor and joint mine-clearance efforts, although technical details and the conditions for a full reopening remain unresolved; one possibility under discussion is the creation of a "designated shipping corridor" through the strait.
How Could
the Strait of Hormuz Reopen?
- To understand the proposal, it is better to go through the geography.
- Before the war, vessels could generally pass through the Strait of Hormuz without being confined to a special corridor. Ships entered from the Persian Gulf and exited into the Gulf of Oman.
- The conflict has changed that. Movement through the strait has been severely restricted, meaning that if commercial shipping resumes, vessels may have to follow a designated route.
- One proposed arrangement would allow ships to enter the Strait of Hormuz from the Persian Gulf and travel largely through waters under Iranian control before passing around the "Musandam Peninsula."
- Musandam is an Omani enclave separated geographically from the rest of Oman. It sits strategically at the mouth of the Strait of Hormuz, as shown in the above infographics.
- Under the proposed arrangement, ships could pass through a corridor in this area before entering the Gulf of Oman.
- One proposal has described a controlled corridor roughly seven miles (11 kilometres) wide, although the final dimensions and operating arrangements remain subject to negotiation.
- Iranian officials have described the proposed arrangement as a single, two-way shipping route—effectively a controlled maritime corridor for vessels entering and leaving the strait for shipping. In practical terms, this could allow at least part of the Strait of Hormuz to reopen without immediately returning to unrestricted maritime traffic.
Why Hormuz
Matters to the World
- The importance of this waterway cannot be overstated.
- In the first half of 2025, about 20.9 million barrels per day of petroleum and other liquids moved through the Strait of Hormuz—roughly one-fifth of global petroleum-liquids consumption. Simultaneously, the strait is also critical for LNG: about 20% of global LNG trade passed through Hormuz in 2024
- At present, the strait is effectively shut to normal commercial traffic, with only a very limited number of vessels being permitted to pass.
- Around 500 ships and 6,000 sailors are reportedly stuck, while the disruption has been far more severe than a simple slowdown: EIA data show petroleum flows through Hormuz averaged just 4.9 million barrels per day in the second quarter of 2026, compared with 21.6 million barrels per day in the fourth quarter of 2025
- That is why even a partial reopening would provide substantial relief to global markets. But reopening the strait is much easier to discuss than to implement.
Iran's
Conditions for Reopening the Strait
- Iran has attached several conditions to a full reopening of the strait, although the exact formulation has varied among Iranian officials.
- Among the demands are-
- An end to the U.S. blockade and military pressure around the waterway,
- Implementation of commitments under the June interim agreement, relief from sanctions and other economic restrictions, and
- Compensation for war-related damage.
- These demands are central to Iran's position. So far, Washington has not publicly responded to them.
- There has, however, been activity by the U.S. Navy involving mines in the waterway. Trump has spoken about a U.S. demining operation. Trump said on Truth Social that the U.S. Navy had removed or detonated mines from international waters in the Strait of Hormuz”
- But the rhetoric from the U.S. president has not disappeared. President Trump has issued a new warning to Iran: if Tehran lays any new mines in the strait, he says they will be destroyed.
- For now, however, those warnings appear to carry less weight than they might have earlier in the crisis.
Why Did Iran
Mine the Strait?
- The central question is why Iran would mine such a strategically important waterway in the first place-the answer is leverage.
- Mining the strait can deter commercial vessels from using the route and give Iran greater control over shipping movements; Iran's strategy illustrates what might be called the "weaponisation of geographical advantage": turning control over a strategically located chokepoint into political and economic leverage. In other words, the mines are not simply a military tool. They are also a means of exerting pressure over one of the world's most important energy chokepoints
- That is precisely the leverage Washington wants to eliminate. The U.S. demining effort therefore has significance beyond clearing a navigational hazard. It represents an attempt to restore freedom of navigation and reduce Iran's ability to control maritime traffic.
Oil Markets
Are Already Betting on De-Escalation
- Financial markets, meanwhile, are responding to the diplomatic signals when crude prices are falling.
- Brent crude, the global benchmark for oil prices, dropped below $90 a barrel and reached a one-week low. One important reason is that traders are increasingly pricing in the possibility of renewed shipping through the strait.
- If vessels can move again, the immediate risk to global oil supplies declines. Markets therefore appear to be pricing in at least some degree of de-escalation, but that optimism should be treated cautiously. Why?
The Bigger
Problem: A Fragile Global Oil Supply System
- Even if the Strait of Hormuz reopens, there is little reason to assume that global energy markets will suddenly become secure just because the broader conflict landscape remains deeply unstable.
- The vulnerability extends beyond Hormuz. "Reuters" analysis of IEA data found that countries affected by major conflicts and geopolitical disruptions—including Iran, Russia, Ukraine, Libya, Kazakhstan and Venezuela—accounted for roughly 45 million barrels per day of global oil output in 2025, more than 43% of the world's total. For this disruption, the four reasons can be attributed to those includes:
- the U.S.-Iran war;
- the Russia-Ukraine war;
- the conflict in Libya; and
- broader restrictions affecting global oil supplies.
- To put the figure into perspective, as a rough illustration of scale, 45 million barrels is an enormous volume of liquid fuel—equivalent to several tens of millions of typical automobile fuel tanks. That is the real vulnerability facing the global economy.
Conclusion-
A Pause, Not a Resolution
- A reopening of Hormuz could reduce the immediate risk premium in energy markets, release stranded vessels, improve regional commercial confidence, and provide some relief to global supply chains. But it would not remove the strategic causes of the crisis.”
- On one hand, in the immediate effect, it could lower the fears of a major energy shock, allow stranded vessels and sailors to move, and reduce pressure on crude prices. Whereas on the other hand, rerouting the region's investment sentiments and economic opening gives regional societies a sense of security.
- Washington has not ruled out further escalation, while Tehran continues to demand guarantees over the strait, sanctions, the U.S. blockade, and commitments associated with the June agreement.
- The diplomatic engagement between Iran and Oman is therefore significant—but fragile. The markets may be betting on de-escalation. The ships may eventually begin moving again. Oil prices may continue to fall. But none of this guarantees lasting stability.
- At best, what the world is witnessing is a pause—not a peace. And in the Strait of Hormuz, even a temporary pause can matter enormously to the global economy.
