If the Strait of Hormuz is squeezed shut, every container that leaves Karachi or Mumbai will have to reroute around Africa, adding weeks to voyages and billions to costs. That is the blunt calculus behind Iran's latest warning to its neighbours: stop helping Washington strangle Tehran's economy or face retaliation. The message, delivered by Mohsen Rezaei of Iran's Supreme National Security Council on state television, is less a negotiation and more a threat wrapped in velvet. It arrives as US President Donald Trump escalates what he calls the "most crushing economic operation" against Iran, a campaign that already includes sweeping sanctions and the threat of "tremendous consequences" for any country that offers Iran a lifeline. For South Asia, the stakes could not be higher. Pakistan and India sit astride the Indian Ocean's western rim, gatekeepers to the Gulf's oil and the maritime corridor that carries half of the world's container traffic. A closure of Hormuz, or even the credible threat of one, would reroute global shipping through the Cape of Good Hope, inflating freight rates, delaying deliveries of fuel and food, and forcing Islamabad and Delhi into a geopolitical choice they have long avoided: whose sanctions regime do they enforce?
The moment South Asia can no longer stay neutral in the Iran-US economic war
This is not a drill. The US is weaponising the dollar, secondary sanctions, and shipping insurance blacklists to sever Iran from the global financial system. Washington's Treasury Secretary Scott Bessent put it plainly: "You're either with us or against us." Iran's response is to threaten those who cooperate with the US with "enemy" status, a phrase that carries legal and kinetic implications under Tehran's security doctrine. The immediate flashpoint is Hormuz, through which 20-30 million barrels of oil transit daily. But the deeper contest is over the loyalty of the region's middle powers, Turkey, the UAE, Oman, Pakistan, and India, whose ports, refineries, and banks sit at the junction of US primacy and Iran's survival strategy. For Islamabad, the dilemma is acute. Pakistan's economy is tethered to Gulf energy, remittances from 9 million workers in the Gulf, and the China-Pakistan Economic Corridor (CPEC) that funnels Chinese goods through Gwadar to Central Asia. Any US-led push to enforce sanctions on Iran would force Pakistan to choose between Washington's market access and Tehran's energy lifeline. Delhi faces a mirror problem: Iran supplies 10-12% of India's oil via the overland route through Chabahar and the sea route around the cape. A rupture here would spike India's import bill, delay fertiliser shipments for its farms, and complicate its strategic outreach to Iran as a counterweight to China's growing influence in the Indian Ocean. The US gambit is to fracture this neutrality by making sanctions compliance a litmus test for economic engagement. Iran's counter-gambit is to make defiance survivable by offering carrots, cheap oil, transit fees, and security guarantees, to those who resist US pressure. The stage is set for a regional showdown that could redraw the trade map of South Asia for decades.
Why this matters: the global choke point that now decides who eats and who pays
The Strait of Hormuz is the world's most important chokepoint for oil and liquefied natural gas. A closure of even a single week would send Brent crude above $150 a barrel, trigger a global recession, and force central banks to choose between fighting inflation and stabilising growth. For South Asia, the impact would be immediate and asymmetric. Pakistan, already reeling from inflation above 30%, would see food inflation spike as wheat and cooking oil prices surge. India, a net oil importer, would face a current-account shock that could wipe out its modest forex reserves and force a sharp rupee devaluation. Beyond the macro numbers, the humanitarian cost would fall hardest on the poor. Pakistan imports 30% of its wheat from Russia and Ukraine; rerouting grain ships around Africa would add 10-15 days to delivery times and push local prices beyond the reach of daily wage earners. In India, diesel shortages would paralyse freight movement, halting food distribution and forcing state governments to ration supplies. The US campaign is not merely economic; it is a form of economic warfare designed to collapse Iran's currency, erode its state capacity, and force a political transition. But the collateral damage in South Asia could be systemic. The region's central banks are already fragile. Pakistan's debt-to-GDP ratio hovers near 80%, while India's banking sector is saddled with $150 billion in stressed assets. A supply shock from Hormuz would push both economies into stagflation, testing the political resilience of governments that are barely holding onto public trust. For Washington, the gamble is that economic pain will fracture Iranian society and force Tehran to capitulate. For Tehran, the counter-gamble is that regional defiance, especially from South Asia, can dilute US pressure by creating enough economic friction to make sanctions unsustainable. The outcome will determine whether the 21st century's trade architecture bends around US primacy or fragments into rival blocs.
Background: from JCPOA to Trump's shock-and-awe sanctions, the road to Hormuz
The current crisis is the third act of a tragedy that began in 2015 with the Joint Comprehensive Plan of Action (JCPOA), the nuclear deal that lifted sanctions on Iran in exchange for curbs on its nuclear programme. When the US withdrew from the JCPOA in May 2018 under President Trump, it reimposed sweeping sanctions aimed at cutting Iran's oil exports to zero. Iran responded with calibrated violations of the nuclear deal and a campaign of regional proxy pressure, targeting Saudi oil facilities, attacking tankers in the Gulf, and supporting Houthi missile strikes on the UAE. The February 28, 2026 escalation marked a qualitative shift: the US and Israel launched coordinated strikes against Iranian nuclear and military sites, triggering a full-scale war. The June 17, 2026 memorandum of understanding (MoU) that called for an "immediate and permanent termination of military operations" collapsed within weeks, as neither side trusted the other to honour terms. Since then, the US has doubled down on economic warfare, while Iran has sought to peel away regional states by offering inducements, discounted oil, transit fees, and security guarantees. The pattern echoes the 1990s when the US imposed secondary sanctions on firms dealing with Iran and Libya. Back then, the EU, China, and India resisted Washington's extraterritorial reach, creating a sanctions-busting network that kept Iranian oil flowing. Today, the stakes are higher: the US is leveraging the dollar's dominance in global trade to force compliance, while Iran is threatening to treat non-compliant neighbours as enemies. The stage is set for a rerun of the 1990s sanctions saga, but with Hormuz as the pressure point and South Asia as the battleground.
What happened: the timeline of escalation that brought us to today
According to reporting by Al Jazeera, the latest escalation began on Wednesday, August 19, 2026, when US President Donald Trump announced a new round of sanctions aimed at "the most crushing economic operation" against Iran. The measures target Iran's remaining oil exports, its shipping insurance networks, and any entity that provides Tehran with "any type of lifeline." The next day, Treasury Secretary Scott Bessent clarified Washington's stance: "You're either with us or against us," he told reporters, signalling that secondary sanctions would apply to any country that facilitates Iran's economy. On Saturday, August 22, Mohsen Rezaei, secretary of Iran's Supreme National Security Council, issued the regime's riposte in an interview with state broadcaster IRIB. "We're telling all nearby countries not to join the US economic war," Rezaei warned. "Otherwise, we will consider them as enemies." He outlined a three-stage Iranian strategy: negotiation, persuasion, and, ultimately, retaliation. "First we negotiate. Then, we try to separate them from America with pleasant language," he said. "But in the third stage, we will definitely act." Rezaei dismissed the US hope that economic pressure would fracture Iranian society, arguing that Tehran's unity would hold even as Washington sought to "break our unity with economic pressure and a group of protesters will take to the streets." The remarks came amid stalled negotiations to end the February 28 war, with control over the Strait of Hormuz remaining the central sticking point. The US insists on unimpeded transit for its warships and allies' tankers; Iran demands guarantees that Hormuz will not be used as a US staging ground for attacks on Iranian territory. The failure of the June 17 MoU to halt hostilities has left both sides preparing for a prolonged economic and military struggle, with Hormuz as the fulcrum.
Global and regional reaction: who lined up and who hedged
The US campaign has drawn explicit support from Israel, which has coordinated military strikes with Washington since February 28. European capitals have been more circumspect, with France and Germany reiterating their commitment to the JCPOA framework but stopping short of defying US sanctions. China and Russia have positioned themselves as Iran's economic lifelines, deepening trade ties and offering alternative payment mechanisms to bypass the dollar. In the Gulf, the UAE and Oman have sought to maintain neutrality, offering themselves as mediators while quietly expanding trade with Iran. Saudi Arabia, by contrast, has thrown its weight behind Washington, seeing an opportunity to weaken Iran's regional influence. In South Asia, the reactions have been cautious. Pakistan's foreign ministry has called for dialogue and warned against "economic warfare that spills over into regional instability." India's external affairs ministry has urged "restraint and de-escalation," while privately exploring contingency plans to reroute Iranian oil through Chabahar and the Cape of Good Hope. Turkey, a NATO member with deep economic ties to Iran, has positioned itself as a mediator, hosting talks between Iranian and Western officials. The UN Security Council has been deadlocked, with the US vetoing any resolution that criticises its sanctions regime and Russia and China vetoing any that condemns Iran's military actions. The pattern is clear: the world is splitting into two blocs, one led by the US that seeks to isolate Iran economically, and another led by China, Russia, and regional hedgers that seeks to keep Iran afloat. South Asia sits at the fault line, with Islamabad and Delhi forced to navigate between Washington's demands and Tehran's inducements.
South Asia impact: the coming choice between Washington's market and Tehran's oil
For Pakistan, the stakes are existential. The country imports 80% of its energy needs, with 40% of its oil arriving from the Gulf via the Strait of Hormuz. Any US-led push to enforce sanctions on Iran would force Islamabad to either comply, risking a domestic backlash and energy shortages, or defy Washington, risking secondary sanctions that could freeze its banks out of the global financial system. The China-Pakistan Economic Corridor (CPEC) adds another layer: Gwadar port, the flagship project of CPEC, is designed to handle Chinese goods bound for Central Asia. But if Hormuz is closed or sanctions-compliant insurers refuse to cover ships calling at Iranian ports, Gwadar could become a white elephant. Pakistan's foreign ministry has so far avoided taking sides, but the economic pressure is mounting. The IMF programme, already delayed, could be derailed if Pakistan is seen as facilitating sanctions-busting trade with Iran. For India, the dilemma is less existential but no less acute. Iran supplies 10-12% of India's oil, delivered via the overland route through Chabahar and the sea route around the cape. A rupture here would spike India's import bill, delay fertiliser shipments for its farms, and complicate its strategic outreach to Iran as a counterweight to China's growing influence in the Indian Ocean. India has invested $500 million in Chabahar port and a $2 billion railway line to Afghanistan, projects that would be stranded if Iran is isolated. The US has not yet demanded that India comply with its sanctions regime, but the pressure is building. If Washington tightens the screws, Delhi will face a stark choice: sacrifice its energy security and strategic investments in Iran or risk its ties with Washington. The regional precedent is instructive. In 2019, when the US demanded that India halt its oil imports from Iran, Delhi complied but compensated by ramping up imports from the US and Saudi Arabia. Today, the US is not merely asking for compliance; it is threatening "tremendous consequences" for any lifeline to Iran. The stage is set for a rerun of 2019, but with far higher stakes.
What happens next: three possible paths and their consequences
Analysts expect three broad trajectories over the next six months, each with distinct consequences for South Asia. The first path is escalation: Iran responds to US sanctions by targeting shipping in Hormuz, either through direct attacks on tankers or by mining the strait. The US retaliates with a naval blockade, drawing in regional states that depend on Hormuz for oil exports. Pakistan and India would face immediate energy shortages, forcing rationing and blackouts. The second path is fragmentation: Iran offers inducements, discounted oil, transit fees, and security guarantees, to regional states, creating a sanctions-busting network that keeps Iranian oil flowing. Pakistan and India would hedge by purchasing Iranian oil through intermediaries, but at a premium that would strain their budgets. The third path is accommodation: the US and Iran reach a temporary truce, perhaps brokered by China or Turkey, that freezes military operations in exchange for limited sanctions relief. Pakistan and India would breathe easier, but the underlying tensions would remain, setting the stage for another crisis. The most likely outcome, according to geopolitical risk analysts, is a hybrid of the second and third paths: Iran succeeds in fragmenting the sanctions regime by offering inducements to regional states, while the US and Iran agree to a de facto truce that keeps Hormuz open but leaves the underlying conflict unresolved. For South Asia, this would mean higher energy costs, slower trade, and a permanent risk of another crisis. The key question is whether Pakistan and India can navigate this hybrid path without triggering either Washington's wrath or Tehran's retaliation. The answer will determine whether South Asia's trade map bends around US primacy or fragments into rival blocs.

Key Takeaways
- Iran's threat to treat neighbours as enemies over US sanctions is not a negotiation, it's a geopolitical ultimatum. Countries like Pakistan and India must now choose between Washington's market access and Tehran's energy corridor, with no neutral ground left.
- The Strait of Hormuz is the fulcrum of the crisis. A closure or credible threat would reroute global shipping, spike energy prices, and force South Asian governments into austerity measures that could trigger social unrest.
- The 1990s sanctions saga offers a cautionary parallel. Back then, India and Pakistan resisted US secondary sanctions by creating a sanctions-busting network. Today, the US is leveraging the dollar's dominance to force compliance, leaving Islamabad and Delhi with far fewer options.
