A Pakistani-flagged tanker recently traversed the Strait of Hormuz by closely following a route near the Iranian coastline, marking a significant development in maritime navigation through one of the world’s most strategic and sensitive waterways. This passage suggests that vessels may now need explicit approval from Iranian authorities to ensure safe transit through the strait, which has become a focal point amid intensifying geopolitical tensions in the Middle East.
The ongoing conflict between the United States, Israel, and Iran has entered its third week, resulting in over 2,000 casualties and showing no signs of abating. The Strait of Hormuz, a narrow passage that facilitates roughly 20 percent of global oil and liquefied natural gas shipments, remains effectively closed off to much of the international maritime traffic. This closure has contributed to soaring energy prices worldwide and heightened fears of inflation, as US allies have largely declined President Donald Trump’s appeals for assistance in reopening this vital corridor.
Detailed vessel-tracking information reveals that the Pakistani tanker named Karachi sailed through a narrow channel between the Iranian islands of Larak and Qeshm on Sunday. The ship maintained open transponder signals during its journey, signaling its position clearly as it hugged the Iranian coast before entering the Gulf of Oman. Following this, two bulk carriers adopted the same route on Monday morning, also openly broadcasting their transit through the strait. This contrasts with many other vessels in the region that have chosen to switch off their transponders to avoid detection and potential threats.
In addition to these movements, two Indian-flagged liquefied petroleum gas tankers passed through the strait in the early hours of Saturday, while a general cargo ship registered under the Gambian flag exited the waterway on Tuesday. However, electronic interference in the area has sporadically scrambled vessel signals, making it difficult to fully track the precise routes of some ships near Larak Island. This interference adds another layer of complexity and risk for maritime operators navigating these contested waters.
Experts from the Asia Maritime Transparency Initiative at the Centre for Strategic and International Studies, including Deputy Director Harrison Prétat, suggest that the use of this coastal route may indicate the establishment of a new traffic control system imposed by Iran. Such a system could involve Tehran targeting vessels or deploying mines along traditional shipping lanes while keeping a safer passage open for ships it deems friendly or approved. This theory aligns with recent patterns where Iran appears to selectively allow certain vessels to transit the strait, thereby exercising greater control over maritime traffic in the region.
Since the onset of US and Israeli military actions more than two weeks ago, Iran has struck multiple vessels in and around the Strait of Hormuz, severely disrupting the flow of maritime traffic. These attacks have left numerous ships stranded within the Persian Gulf, while others have been unable to enter the waterway altogether. The resulting bottleneck has sent shockwaves through global energy markets, underscoring the strait’s critical role in international trade and energy security.
Financial institutions and analysts have noted that this evolving situation effectively creates a scenario where the Strait of Hormuz is not officially closed but where passage increasingly depends on political negotiations and tacit agreements with Tehran. JPMorgan Chase & Co analysts, including Natasha Kaneva, have highlighted this emerging dynamic, emphasizing how it complicates the free movement of vessels and adds uncertainty to global energy supplies.
Under normal circumstances, ships avoid sailing so close to Iranian shores due to longstanding security concerns. Standard navigation routes typically direct vessels exiting the strait toward the opposite side of the channel, minimizing exposure to potential threats. However, recent attacks on ships following traditional paths have prompted some to reconsider their routes, opting instead for the Iran-approved corridor between Larak and Qeshm islands.
Maritime security expert Martin Kelly has suggested that this pattern may represent the beginning of a verification process by Iranian authorities, whereby ships must receive explicit approval to transit the strait via this specific passage. While these authorized transits have provided some reassurance to oil traders, the proximity of the route to Iranian territory continues to raise alarms among insurers and banks involved in financing commodity shipments. Insurance policies often classify such zones as high-risk, and financial institutions may issue compliance warnings when vessels operate near Iranian waters.
Despite these developments, the number of ships utilizing the Iran-approved route remains a small fraction of the usual maritime traffic through the Strait of Hormuz. As Harrison Prétat points out, these limited authorized passages fall significantly short of restoring the typical volume of shipping and energy flows from the region. The situation remains fluid, with the potential for further disruptions as the geopolitical conflict continues to unfold.
