On June 2024, Iran publicly offered to reopen the Strait of Hormuz for international navigation, conditional on the United States lifting its naval blockade and ceasing hostile military actions in the Persian Gulf. The Strait, a narrow maritime chokepoint between the Persian Gulf and the Gulf of Oman, is critical for global energy supplies. Iran’s Islamic Revolutionary Guard Corps Navy (IRGCN) exerts de facto control over the Strait, which sees approximately 21 million barrels per day (mbpd) of oil transit, nearly 20% of global petroleum liquids (International Energy Agency [IEA], 2023). This offer underscores the strategic leverage Iran holds over a vital international waterway and reflects the ongoing geopolitical contest between US naval policies and regional security dynamics.

Legal Framework Governing the Strait of Hormuz

The United Nations Convention on the Law of the Sea (UNCLOS) 1982 governs maritime navigation rights through straits used for international navigation. Part III (Territorial Sea and Contiguous Zone) and Part V (Exclusive Economic Zone) define coastal states’ sovereignty and rights, while Part VII covers the high seas. The Strait of Hormuz lies within the territorial seas of Iran and Oman, but UNCLOS guarantees transit passage rights for all vessels, including military ships, without prior notification or permission (UNCLOS, Articles 37 and 38).

• The US conducts Freedom of Navigation Operations (FONOPs) to challenge excessive maritime claims and maintain open sea lanes, including in the Strait.
• Iran’s Islamic Penal Code (2013) criminalizes foreign naval blockades and considers them acts against national security.
• UN Security Council Resolution 2231 (2015)

Despite UNCLOS provisions, the US naval blockade and Iran’s retaliatory measures reflect a legal and operational contest over the Strait’s governance and security.

Economic Significance and Impact of Disruptions

The Strait of Hormuz is a critical artery for global energy markets. According to the IEA (2023), about 21 mbpd of oil passes through the Strait, accounting for nearly 20% of global petroleum liquids supply. Disruptions here cause immediate ripple effects on global oil prices and energy security.

• The World Bank (2023) estimates that a blockade or closure of the Strait could increase global oil prices by 10-15%, exacerbating inflationary pressures worldwide.
• Iran’s oil exports, which stood at 2.5 mbpd before US sanctions, plummeted below 0.5 mbpd during peak sanctions periods, costing Iran over $10 billion annually in lost revenues (OPEC Annual Statistical Bulletin, 2023).
• The US Navy’s 5th Fleet, tasked with securing the Strait, has an annual budget allocation of approximately $1.5 billion (US Department of Defense Budget, 2024), reflecting the strategic priority given to this region.

The economic stakes explain why both Iran and the US maintain aggressive postures, with the former leveraging the Strait as a bargaining chip and the latter seeking to ensure uninterrupted energy flows.

Geopolitical Actors and Security Dynamics

The Strait of Hormuz’s security is contested primarily by Iran and the United States, involving multiple regional and international stakeholders.

• Iran’s IRGCNDefence Weekly), signaling readiness to enforce its claims.
• The US Navy 5th Fleet operates from Bahrain, conducting patrols and FONOPs to counter perceived Iranian threats and maintain freedom of navigation.
• The United Nations Security Council
• OPEC

The absence of a multilateral security framework involving all Persian Gulf littoral states and major naval powers creates a security vacuum, leading to unilateral actions such as US naval blockades and Iranian retaliations, increasing risks of escalation.

Comparative Analysis: Strait of Hormuz vs Malacca Strait

The Malacca Strait’s success in reducing maritime risks through multilateral cooperation contrasts sharply with the Strait of Hormuz’s volatility driven by unilateral security postures.

Strategic Implications and Way Forward

• Iran’s conditional offer to reopen the Strait highlights the leverage chokepoints provide in geopolitical bargaining.
• Legal adherence to UNCLOS provisions on transit passage must be reinforced to prevent escalation.
• A multilateral security framework involving Persian Gulf littoral states, the US, and other stakeholders is critical to stabilize the region.
• Energy market stakeholders, including OPEC and IEA, should coordinate contingency planning to mitigate disruption risks.
• Diplomatic efforts to revive or replace the JCPOA could reduce tensions and ensure maritime security.
