For 70 years, the Strait of Hormuz has been an open artery for the world's oil. But on Friday, Donald Trump announced that the US would declare it American territory, transforming the world's most critical shipping lane into a geopolitical flashpoint overnight. The move comes as the US and Iran remain locked in a grinding war that has already throttled global energy flows, triggered a blockade, and turned the strait into a killing zone for commercial vessels. For South Asia, a region that imports 60% of its oil and depends on the Gulf for trade, the stakes could not be higher. If Trump follows through, the declaration would shred the legal framework governing the strait, invite Iranian retaliation, and force Islamabad to choose between Washington's protection and Tehran's wrath. The question is no longer whether the war will spread, it's whether the world's energy map will be redrawn before the next tanker is sunk.
Why this announcement could redraw the map of global power
Trump's declaration is not just a rhetorical flourish; it is a direct challenge to the 1982 United Nations Convention on the Law of the Sea (UNCLOS), the treaty that defines territorial waters and navigational rights. By declaring the Strait of Hormuz, through which 20% of the world's oil transits, "US territory," Trump is asserting that America can enforce its own rules on a waterway that has historically been governed by international law. This would set a precedent that other states could exploit: imagine China declaring the South China Sea its "territory," or Russia doing the same for the Black Sea. The move would also embolden Washington to escalate its blockade, turning the strait into a de facto American lake. For the global economy, the risk is immediate: oil prices could spike, shipping insurance premiums could soar, and supply chains from Mumbai to Shanghai could fracture. The US midterm elections are just weeks away, and Trump's announcement is clearly aimed at rallying his base with a promise of "victory" over Iran. But the real victory may belong to those who profit from chaos, oil traders, arms dealers, and maritime insurers, while the rest of the world pays the price.
The Strait of Hormuz: A history of brinkmanship and the path to war
The Strait of Hormuz has been a powder keg since the 1979 Iranian Revolution, when Ayatollah Khomeini declared the waterway a "red line" for Iran. The US has long treated the strait as a vital interest, but it has never claimed it as territory. Instead, Washington has relied on a mix of military presence, sanctions, and alliances to keep the waterway open. The current war began on February 28, 2026, when the US and Israel launched a series of preemptive strikes against Iran's nuclear and military infrastructure. Iran responded by restricting traffic through the strait, citing its claim that part of the waterway falls within its territorial waters, a claim disputed by the US and most of the international community. The two sides have since settled into a pattern of uneasy ceasefire talks, punctuated by violations and renewed fighting. In June 2026, they signed a memorandum of understanding (MOU) to halt military operations, but both sides accused the other of breaches within weeks. The US has since established a blockade, firing on vessels it accuses of attempting to reach Iranian ports. Iran, meanwhile, has continued to target commercial ships, arguing that the blockade is illegal. The war has already disrupted global oil supplies, with Brent crude prices fluctuating between $90 and $110 a barrel. But Trump's declaration would take this disruption to a new level, transforming a localized conflict into a systemic threat to the world's energy architecture.
What Trump actually said, and what it means for the war
Speaking to a crowd of law enforcement officials in New York on Friday, Trump framed his declaration as a public service for the world. "After we finish defeating Iran, which is being very badly defeated, pretty soon I'll be declaring the Hormuz Strait a territory of the United States," he said, with a chuckle. "You just have to remember that what we're doing is a great service for the world. Not only for ourselves, for the world. The blockade is unstoppable. It's a wall of steel." The remarks were delivered during a rally to support Republican candidates ahead of the 2026 midterm elections, where control of Congress hangs in the balance. Trump's claim that Iran is "being very badly defeated" is contradicted by the facts on the ground: the war has continued with no clear end in sight, and Iran has shown no signs of surrendering. Instead, it has escalated its attacks on shipping, forcing the US to tighten its blockade. The US has also accused Iran of violating the June MOU, which required Iran to make "best efforts for the safe passage of commercial vessels." Iran, in turn, has accused the US of violating the agreement by enforcing a blockade. The war has already spread beyond the strait, with Iran-backed militias launching attacks on US bases in Iraq and Syria, and the US responding with airstrikes. But Trump's declaration would escalate the conflict to a new level, turning the strait into a direct battleground between the two sides. According to reporting by Al Jazeera, the US has already established a blockade in the strait, firing on a cargo vessel this week for attempting to reach Iranian ports. The blockade is designed to strangle Iran's economy, but it also risks triggering a wider regional war, or even a direct confrontation between the US and Iran.
Global and regional reaction: From condemnation to cautious alignment
The announcement has drawn sharp reactions from governments and international bodies. The European Union has warned that Trump's declaration could violate international law and destabilize global trade. "The Strait of Hormuz is a vital waterway for the global economy, and any unilateral declaration that undermines its status could have serious consequences," said a spokesperson for the European Commission. The United Nations has also expressed concern, with Secretary-General António Guterres calling for restraint. "The rules-based international order must be upheld," Guterres said in a statement. "Any action that threatens the freedom of navigation in the Strait of Hormuz is a threat to global peace and security." China and Russia have been more circumspect, with both countries calling for dialogue but stopping short of condemning the US. China, which imports 10% of its oil from the Gulf, has warned that the escalation could disrupt energy supplies. "We urge all parties to exercise restraint and avoid actions that could further escalate tensions," said a spokesperson for the Chinese Foreign Ministry. Russia, which has been supplying arms to Iran, has also called for dialogue, but its tone has been notably muted. The muted response from Beijing and Moscow suggests that they are weighing their options, with both countries likely to benefit from a prolonged disruption to US dominance in the Gulf. Meanwhile, Gulf states like Saudi Arabia and the UAE have been conspicuously silent, reflecting their growing dependence on US military protection. The silence is deafening: if the US declares the strait its territory, these states may have little choice but to accept the new reality, or risk being left vulnerable to Iranian retaliation.
South Asia impact: Energy bills, trade routes, and the CPEC dilemma
For South Asia, the stakes could not be higher. The region imports 60% of its oil, with 80% of those imports transiting the Strait of Hormuz. A prolonged disruption to shipping through the strait would send oil prices soaring, pushing inflation to levels not seen since the 1970s oil shocks. Pakistan, which imports 85% of its oil, would be hit hardest, with its current account deficit already stretched thin. The country's energy crisis of 2022, which saw blackouts lasting up to 18 hours a day, could pale in comparison.
India, which imports 70% of its oil from the Gulf, would also face severe consequences. The country's refineries, already operating at reduced capacity due to high crude prices, could grind to a halt. The government's efforts to diversify its energy sources, including a push to import oil from Russia, would be insufficient to offset the loss of Gulf supplies. Bangladesh, which relies on the strait for its liquefied natural gas (LNG) imports, would see its energy security collapse, triggering blackouts and industrial shutdowns. The economic fallout would be compounded by a refugee crisis, as Iran-backed militias in Afghanistan and Pakistan could exploit the chaos to launch attacks on vulnerable border regions. The US declaration would also force South Asian states to take sides in a conflict that has no clear resolution. Pakistan, which has historically maintained a balancing act between Saudi Arabia and Iran, would be forced to choose between its Gulf allies and its ideological affinity with Tehran. India, which has deepened its ties with the US under the Quad framework, would face pressure to support Washington's blockade, even as it risks alienating its energy suppliers. The CPEC, Pakistan's flagship infrastructure project, would be particularly vulnerable. The corridor relies on stable energy supplies from the Gulf, and any disruption could force Islamabad to seek alternative financing, or face default. Meanwhile, China, which has invested heavily in CPEC, would be forced to reassess its strategy, potentially rerouting its energy imports through the Malacca Strait and leaving Pakistan as a stranded middleman. The US declaration would not just redraw the map of the Gulf, it would reshape the economic and security architecture of South Asia.
Historically, South Asia has faced similar crossroads. In 2019, Pakistan's decision to allow Saudi Arabia to establish a military base in Gwadar was seen as a strategic move to counter Iran. But the move backfired, triggering a diplomatic crisis with Tehran and forcing Islamabad to walk back its decision under pressure from China. The current crisis is far more consequential: a US declaration over the Strait of Hormuz would force Pakistan to confront the same dilemma, but with stakes that could sink the country's economy and its relationship with Beijing.
What happens next: A world on the brink of a new energy war
The most likely outcome is a prolonged standoff, with the US enforcing its blockade and Iran retaliating with asymmetric attacks on shipping. Analysts expect oil prices to remain volatile, with Brent crude fluctuating between $90 and $120 a barrel in the short term. The US midterm elections could provide a temporary reprieve, as Trump may dial back his rhetoric to avoid alienating swing voters. But the structural forces driving the conflict, US determination to cripple Iran's economy, Iran's refusal to surrender, and the strait's centrality to global energy, mean that the standoff is unlikely to end anytime soon. A key question is whether China and Russia will intervene to protect their energy supplies. Beijing has already signaled its willingness to reroute its oil imports through the Malacca Strait, but the cost of doing so would be high. Russia, meanwhile, could increase its oil exports to China and India, but its ability to offset the loss of Gulf supplies is limited. Another possibility is a regional escalation, with Iran-backed militias launching attacks on US bases in Iraq and Syria, or even on Gulf states that support the US blockade. The US could respond with airstrikes on Iranian territory, triggering a wider war. The least likely but most dangerous scenario is a direct confrontation between the US and Iran, with both sides miscalculating the other's red lines. The risk of such an outcome is heightened by Trump's unpredictable leadership style and Iran's history of brinkmanship. For South Asia, the most immediate concern is the economic fallout. A prolonged disruption to oil supplies would push inflation to double digits, trigger currency crises, and force governments to impose austerity measures. Pakistan, in particular, could face a balance-of-payments crisis, with its foreign reserves already depleted by the energy crisis of 2022. The US declaration would also force Islamabad to confront its reliance on CPEC, which has failed to deliver the promised economic dividends. The corridor's future would hinge on China's willingness to continue funding it, even as the US blockade threatens to strangle Pakistan's economy. The most plausible resolution is a return to the negotiating table, with both sides seeking a face-saving compromise. But the history of US-Iran relations suggests that any deal would be fragile and short-lived. In the meantime, the world's energy architecture is being redrawn, and South Asia is in the crosshairs.
