Iran Strait of Hormuz Closure: Shipping Crisis & Oil Price Surge – Latest Updates

The Strait of Hormuz, a chokepoint for global energy supplies, remains constricted as tensions escalate following the US-Israel conflict with Iran. While a complete closure has been averted, maritime traffic has plummeted, disrupting oil and gas flows and sending ripples through global markets. Recent data indicates a trickle of vessels are still navigating the waterway, some opting for a new, Iranian-controlled corridor, raising questions about safety, costs and international control.

A Lifeline Constricted: The State of Shipping Through the Strait

For over two weeks, maritime traffic through the Strait of Hormuz has been severely disrupted. Before the conflict began four weeks ago, an average of 138 ships transited the waterway daily, carrying approximately a fifth of the world’s oil and gas, and a third of the global fertilizer supply necessary for half of the world’s food production. In March, that number dwindled to an estimated total for the entire month, with roughly 100 vessels exiting the Gulf and only 40 entering, according to Lloyd’s List Intelligence. More than 20 ships have been attacked in the region during the conflict, including the Palau-flagged Skylight, which was struck off the coast of Oman, resulting in the deaths of two Indian crew members. Threats to shipping have effectively closed the strait, upending global oil and gas supplies.

Tehran’s Tollbooth: A New Shipping Corridor and Emerging Costs

Despite the dangers, a limited number of vessels continue to transit the Strait, with many choosing a route dictated by Iran. Tehran has established what analysts at Lloyd’s List are calling a “safe corridor” within Iranian territorial waters, located close to the Iranian coastline between Larak island and the mainland. This allows Iranian authorities, particularly the Revolutionary Guards (IRGC), to “verify” vessels and grant approval for passage. The move is widely seen as an attempt by Iran to exert control over traffic in the strait and, potentially, generate revenue. Iran has been keen to divert vessels from the standard commercial shipping lane through the middle of the strait to this new corridor.

The question of payment for safe passage remains a point of contention. While official statements are scarce, reports suggest that at least two vessels have paid to transit the strait, with one payment reportedly reaching $2 million (£1.5m) for a Very Large Crude Carrier (VLCC). These payments were allegedly made in Chinese yuan, likely due to sanctions imposed on the IRGC by the US, EU, and UK. However, Iranian approval does not guarantee safety, as the IRGC operates with internal factions that could still delay or seize vessels despite official clearance.

The Wider Implications: Energy Markets, Global Trade, and International Response

The disruption to shipping through the Strait of Hormuz has significant implications for global energy markets. The strait is a critical artery for oil and gas exports from the Middle East, and any prolonged closure or restriction could lead to substantial price increases and supply shortages. The impact extends beyond energy, affecting the transport of fertilizers essential for global food production. Iraq, the world’s sixth-largest oil producer, has already been forced to cut oil production in Basra by 70%, as the majority of its exports pass through the strait. Saudi Arabia temporarily shut down its largest refinery, Ras Tanura, which processes 550,000 barrels per day. Iran’s closure of the Strait of Hormuz is an international crisis, with repercussions felt globally.

The crisis likewise poses a humanitarian challenge, with over 1,000 vessels and their crews stranded in the Gulf, facing stressful conditions and dwindling supplies. The UN’s shipping agency, the International Maritime Organization (IMO), has raised concerns about the welfare of these 20,000 seafarers. The situation is further complicated by the fact that many ships are opting to remain at anchor or in port, unwilling to risk navigating the strait.

Diplomatic Efforts and the Search for a Resolution

International efforts to address the crisis are underway. More than 30 countries have signed a joint statement agreeing to work on “appropriate efforts” to safeguard the waterway. The United Kingdom has offered to host an international security summit to develop a “viable, collective plan” to reopen the strait. However, a lasting resolution hinges on de-escalating the broader conflict between the US-Israel and Iran. President Trump recently extended a pause on striking Iranian energy infrastructure until April 6, citing “very well” progressing talks with Iran, and noting Iran requested “more time.” He also alluded to the possibility of seizing Iranian oil, though he quickly downplayed the idea.

What’s Confirmed and What Remains Unclear

Confirmed: Maritime traffic through the Strait of Hormuz is significantly disrupted. Iran is controlling access through a new “safe corridor” within its territorial waters. Some vessels are paying to transit the strait. The disruption is impacting global energy markets and food production. International diplomatic efforts are ongoing.

Unclear: The exact number of vessels paying for passage through the Iranian corridor. The long-term impact of the disruption on global oil prices and supply. The effectiveness of international diplomatic efforts. The extent to which the IRGC’s internal factions will adhere to official transit approvals. The full extent of the damage to vessels that have been attacked.

Looking Ahead: Procedural Next Steps and Potential Scenarios

The immediate future will likely see continued restricted traffic through the Strait of Hormuz, with vessels continuing to assess the risks and costs of transit. The success of the UK-hosted security summit, should it materialize, will be crucial in coordinating an international response. The IMO will likely continue to monitor the situation and advocate for the safety of seafarers. The key procedural step remains the progress of direct negotiations between the US and Iran, as any lasting solution will require a broader de-escalation of tensions. The coming weeks will be critical in determining whether the Strait of Hormuz can be reopened to normal commercial traffic, or whether it will remain a chokepoint in a volatile geopolitical landscape.
