The global energy crisis has intensified as Iran's closure of the Strait of Hormuz reaches its 17th day, prompting U.S. President Donald Trump to consider a 'Hormuz coalition' and the potential seizure of Kharg Island. While some vessels from India and Turkey have been granted passage, the blockade has severely disrupted oil supplies and pharmaceutical air routes, threatening the availability of critical cancer medications. The European Union has signaled a reluctance to expand its naval presence despite mounting pressure.
Military Escalation Risks
President Trump is exploring the seizure of Iran's primary oil hub, Kharg Island, despite warnings from U.S. oil companies about worsening the energy crisis.
Global Supply Chain Impact
The blockade is not only spiking oil prices but also disrupting air freight for essential pharmaceuticals, specifically targeting cancer drug supplies.
EU Diplomatic Stance
Kaja Kallas stated the EU has no appetite to expand its current naval mission into the Strait of Hormuz, complicating a unified Western response.
The conflict between the United States, Israel, and Iran entered its 17th day on March 16, 2026, with Iran's effective closure of the Strait of Hormuz sending shockwaves through global energy and supply chain markets, as a rare sighting of a non-Iranian tanker transiting the strait with its transponder active drew international attention, according to ANSA. The blockade has prompted U.S. President Donald Trump to explore aggressive countermeasures, including the formation of a so-called "Hormuz coalition" and the potential military seizure of Iran's Kharg Island oil hub, according to a report by Axios cited by Reuters. Fears of a deepening global energy crisis have mounted as U.S. oil companies warned the White House that conditions could deteriorate further, while the European Union signaled it has no intention of expanding its naval presence to the strait. Iran's Revolutionary Guards declared passage through the Strait of Hormuz "not allowed" for foreign ships as early as February 28, 2026, according to an EU naval mission official cited by Reuters. On March 12, 2026, Iran's foreign ministry stated that ships must coordinate with Iran's navy to pass through the strait, Reuters reported. The current conflict, now in its 17th day, has involved U.S.-Israeli strikes on the Iranian capital, with an Israeli artillery unit also active amid the broader escalation, according to Reuters and web search results from March 16, 2026.
Iran selectively allows Indian and Turkish vessels through Iran has not applied its Hormuz blockade uniformly, permitting ships from select countries to transit the strait under specific conditions, according to Kathimerini. Indian officials confirmed that Iran recently allowed two Indian liquefied petroleum gas tankers to pass through the strait after coordination with Iranian naval authorities, as reported by Reuters. Turkish vessels have also been permitted passage under similar arrangements, according to Kathimerini. The appearance of a non-Iranian tanker transiting the strait with its locator switched on was described as a rare occurrence during the current blockade, ANSA reported. The selective enforcement of the closure has complicated the international response, as some countries maintain functional, if constrained, maritime access while others face a full embargo on their shipping.
Trump weighs Kharg Island seizure as oil shock deepens Trump is considering the formation of a multilateral "Hormuz coalition" to break the Iranian blockade and has also discussed the potential seizure of Kharg Island, Iran's principal crude oil export hub, according to Axios as cited by Reuters. The island sits approximately 25 kilometres off the Iranian coast and handles the bulk of Iran's oil export capacity, making it a central target in any strategy to restore energy flows to global markets. U.S. oil companies have separately warned Trump that the energy crisis stemming from the conflict could worsen further, according to the Wall Street Journal as reported by ANSA. Reuters reported on March 16 that the United States is rapidly exhausting the tools at its disposal to absorb the oil price shock caused by the war with Iran. The convergence of a physical blockade, diplomatic paralysis, and depleted policy buffers has placed Washington under mounting pressure to escalate or negotiate.
Pharmaceutical supply chains buckle as air routes close Beyond energy markets, the war has begun disrupting global pharmaceutical supply chains, with air routes through the Middle East affected by the conflict, according to Reuters. The disruption poses a specific risk to the supply of critical medications, including cancer drugs, Reuters reported. The EU High Representative Kaja Kallas indicated that the European Union has no appetite to expand its existing naval mission to cover the Strait of Hormuz, according to reporting cited in the day-17 summary published by Sud Ouest. Lebanon was also described as increasingly cornered by the regional conflict, with the Gulf states facing economic asphyxiation as the blockade persists, according to Sud Ouest. The combination of energy disruption, pharmaceutical shortages, and regional destabilization marks the 17th day of the conflict as a turning point in its global economic impact.
