In the turbulent waters of the Strait of Hormuz, where a fifth of the world’s crude oil and liquefied natural gas passes through a narrow maritime corridor, a high-stakes drama is unfolding. As of March 16, 2026, the strait—just 21 nautical miles wide at its narrowest—has become a flashpoint in the ongoing U.S.-Israeli war on Iran, with Tehran’s aggressive tactics effectively shutting down one of the globe’s most critical shipping routes. More than 1,000 cargo ships, mainly oil and gas tankers, have been blocked from passing through, according to The Guardian, raising alarms about the potential for a severe global economic crisis.
Yet, in the midst of this blockade and rising oil prices, a remarkable event signaled a glimmer of hope for at least one nation. Ship-tracking data reviewed by Reuters revealed that the Aframax tanker Karachi, operated by Pakistan National Shipping Corporation, successfully transited the strait around March 15 after loading crude at Das Island in Abu Dhabi. The vessel, broadcasting its AIS signal, was the first non-Iranian cargo to make the journey since the conflict began, and is expected to arrive in Karachi on March 17. The data showed the Karachi sailing along the Iranian side of the strait before turning east toward Pakistan, a route fraught with danger given recent attacks by Iran on ships in the Gulf.
Pakistan’s reliance on imported crude and refined fuels from Gulf producers is well-known, with the vast majority of its energy supplies traveling through the Strait of Hormuz. The recent closure of the strait, coupled with Iran’s attacks and mine-laying activities, has sent oil prices soaring and forced Islamabad to make tough decisions at home. On March 9, the government announced that schools would close for two weeks and only 50% of government staff would be permitted in offices—excluding essential services—in a bid to conserve fuel. The austerity measures, as reported by Reuters, underscore the gravity of the situation: with energy supplies at risk, every drop counts.
Despite the closure, Iran has allowed some vessels safe passage. Treasury Secretary Scott Bessent confirmed that, apart from the Pakistani tanker, some Indian, Chinese, and Iranian fuel tankers had also managed to transit the strait. MarineTraffic, a vessel data provider, noted in a post on X that the Karachi’s passage suggested “select shipments may be receiving negotiated safe passage.” While the specifics of these negotiations remain shrouded in diplomatic secrecy, the implications are clear: in a region where alliances and enmities shift with the tides, backchannel deals can mean the difference between energy security and crisis.
Pakistan’s diplomatic balancing act has rarely been more delicate. The country enjoys good relations with Iran, maintains close ties with Washington, and has a mutual defense pact with Saudi Arabia. As tensions escalate, Islamabad finds itself walking a diplomatic tightrope. Iranian Foreign Minister Seyed Abbas Araghchi publicly thanked Pakistan for its “solidarity” in a post on X, a gesture that speaks volumes about the behind-the-scenes coordination. A military source told Reuters that Pakistan’s navy had contacted Iranian counterparts about shipping security, but “no escort was needed, being Pakistani vessels.” The country’s navy, military, and several ministries declined to comment further, perhaps wary of stoking tensions or revealing sensitive strategies.
Meanwhile, another Pakistan National Shipping Corporation tanker, the Lahore, was reported to be about three vessel days from Pakistan after loading crude at Saudi Arabia’s Red Sea port of Yanbu. Pakistan’s finance ministry tried to reassure the public, stating on March 16 that petroleum stocks were “comfortable,” with supply secured for March and cargo coverage into mid-April. The ministry also emphasized efforts to diversify fuel imports, a prudent move given the region’s volatility.
But for the rest of the world, the closure of the Strait of Hormuz is no minor inconvenience. The Guardian highlighted that the strait is the only maritime passage out of the Gulf and handles about a quarter of the world’s liquefied natural gas and seaborne oil trade. The shipping lanes, just two miles wide for inbound and outbound traffic, are separated by a two-mile-wide meridian—leaving little room for error or evasion. Iran’s proximity to these lanes, with some areas just three to four miles from its coast, means that ships have less than two minutes to react to missile or drone attacks. In recent days, Iran has not only attacked ships but also reportedly started laying mines, raising the stakes for any vessel attempting the passage. Last week, a remote-controlled boat laden with explosives was used to damage a crude oil tanker anchored in Iraqi waters, a stark reminder of the ever-present danger.
U.S. military planners had long warned that Iran could close the strait in the event of conflict, but the Trump administration appears to have been caught off guard by the speed and severity of Tehran’s response. Energy Secretary Chris Wright admitted on March 12 that the U.S. Navy was not yet ready to carry out escort operations, stating, “We’re simply not ready,” and explaining that “all of our military assets right now are focused on destroying” Iran’s military resources. The complexity of the situation is compounded by Iran’s use of small, fast boats for mine-laying and the psychological threat posed by sea mines, which can be deployed up to 50 meters below the surface and triggered by contact or remotely.
Amid calls for an international naval coalition to reopen the strait, enthusiasm among potential partners has been notably muted. President Trump, according to The Guardian, named the UK, China, France, Japan, and South Korea as possible contributors, but most have declined or delayed participation. Japan’s Prime Minister Sanae Takaichi stated there were no current plans to send naval vessels to the Middle East, and both Germany and Australia have ruled out deploying forces. France emphasized its focus on regional stability, while South Korea appeared to be slow-walking the U.S. request. The UK has indicated a possible deployment of drone mine hunters but remains skeptical about sending ships for the high-risk mission. As of now, there is no international coalition in place, and the prospect of one forming soon seems slim.
For its part, the U.S. has dispatched 2,000 marines from the 31st Marine Expeditionary Unit, based in Okinawa, toward the Middle East. They are expected to arrive in about two weeks, but analysts caution that this force may be insufficient to counter Iranian shore-based missile batteries or secure the vast area involved. Some have suggested that a ground operation would be required to neutralize Iran’s missile and drone threat—a daunting and potentially escalatory prospect.
As the crisis continues, the world watches with bated breath. For Pakistan, the successful passage of the Karachi tanker is a small but significant victory, testament to the power of diplomacy amid chaos. Yet the broader risks remain: so long as the Strait of Hormuz is at the mercy of conflict, the global energy market—and the economies that depend on it—hang in the balance.
