Introduction<\/strong><\/h2>\n

Maritime straits are considered the jewels of the world’s waterways due to their strategic and economic importance. They serve as vital navigational passages linking two oceans or seas and control a significant portion of global trade and energy flows. Consequently, these waterways constitute important geostrategic and geopolitical chokepoints. The Strait of Hormuz ranks among the most important maritime passages in the world. It is located at the entrance to the Arabian Gulf, between the Musandam Peninsula of the Sultanate of Oman to the south and Iran to the north. The strait extends for approximately 990 kilometers and varies in width from 55 to 95 kilometers. Around 20 percent of the world’s crude oil supply passes through it\u2014equivalent to about 21 million barrels per day\u2014as well as roughly 20 percent of global liquefied natural gas (LNG) trade.[1]<\/a><\/p>\n

The Strait of Hormuz has long been a focal point of political, economic, and security conflicts and disputes due to its strategic location linking the Gulf states with the outside world. Its geographical position has significantly enhanced its importance among nations, making it the object of attention for states with vital interests in the region and a central arena of both international and regional competition. This location has enabled the strait to exert considerable influence over maritime navigation while conferring upon it a distinctive security, legal, and strategic status. Consequently, it has become a site of rivalry among international and regional naval powers seeking to establish control and influence over it because of its importance and geopolitical significance.<\/p>\n

As an international strait, the Strait of Hormuz is governed by the rules of maritime navigation, most of which guarantee freedom of passage for the vessels of all regional and international states. It is also intended to remain neutral during armed conflicts in accordance with the provisions of the 1982 United Nations Convention on the Law of the Sea (UNCLOS), the principal international agreement regulating transit through maritime straits and the primary legal reference in this field. Under the convention, all vessels\u2014civilian and military alike, whether belonging to coastal or landlocked states\u2014have the right to transit international straits without prior authorization, provided that such passage is conducted peacefully and does not threaten the security of the states bordering the strait.<\/p>\n

This article offers an analytical perspective on the impact and significance of the geopolitical location of the Strait of Hormuz on international trade and the transit of oil and gas products from the Arabian Gulf (as referred to by the Arab Gulf states) or the Persian Gulf (as referred to by Iran) to the industrialized countries of both East and West. It also examines the movement of goods and commodities from these countries to the Gulf states. In addition, the strait constitutes a major security nexus for many regional countries, foremost among them Saudi Arabia, Kuwait, Iraq, Qatar, the United Arab Emirates, and Bahrain, all of which are compelled to engage with this strategic challenge through a degree of power diplomacy.<\/p>\n

This dynamic is largely shaped by Iran\u2019s policy of seeking to influence and, at times, leverage the strait as a geopolitical pressure point in response to Western pressure and sanctions imposed by Washington and its allies. Accordingly, the article focuses on the geoeconomic and geopolitical dimensions of the Strait of Hormuz, Iran\u2019s regional influence, and its security and military activities, as well as their impact on regional and international policies. The analysis is grounded in realist theory, which emphasizes power and competition for dominance as essential means of safeguarding national interests within an anarchic international system.<\/p>\n

The significance of this article stems from the importance of the Strait of Hormuz\u2019s location. Therefore, its analysis must be grounded in the methodologies of scientific research within the field of political geography, as the strait\u2019s location directly influences state policies and decision-making regarding economic and military activities conducted through it. Accordingly, the study draws upon the historical method, in addition to the descriptive-analytical method<\/strong>, to examine the importance of the Strait of Hormuz and the impact of its location on the movement of oil, gas, goods, and commodities. It also explores how these dynamics shape the nature of international conflict and regional competition, as well as the role of maritime straits\u2014particularly the Strait of Hormuz\u2014as geographical chokepoints that enable controlling states to exert influence over the economies of countries dependent on transit through them. Furthermore, the study employs the realist approach, which interprets Iran\u2019s behavior through the lenses of power and national interest.<\/p>\n

In line with these objectives, this article first examines the economic significance of the Strait of Hormuz for Iran. Second, it analyzes the political importance of the strait in relation to Iran\u2019s strategy of regional influence. Third, it addresses the security and military dimensions of the strait and their impact on regional and international policies.<\/p>\n

This article is grounded in the core principles of Realist Theory in international relations, particularly its concepts of power, balance of power, and national interest, as these provide the most appropriate framework for understanding and analyzing the subject under discussion. Realism has dominated approaches to foreign policy analysis since the end of the Second World War because it offers highly effective explanatory tools for interpreting state behavior.[2]<\/a><\/p>\n

Realism is regarded as one of the most influential theories of foreign policy. It is founded on the premise that interest constitutes the essence of political action, while power serves as its principal instrument for ensuring survival. According to the realist perspective, national interest is the decisive criterion guiding any form of external behavior adopted by a state within the international system.[3]<\/a><\/p>\n

Realist theory is founded on several core assumptions, foremost among them the view that the state is a rational actor seeking to advance its interests, particularly the protection of its existence and survival within an international system characterized by anarchy. Realism further assumes that the orientations and decisions adopted by states can generally be explained through a rational logic based on an analysis of the dominant political current within each state.[4]<\/a><\/p>\n

Moreover, realism holds that the international system is inherently anarchic. Consequently, the preservation of national security becomes the supreme interest of every state. Foreign policies are therefore directed toward the maximization of power, independent of moral or normative considerations, as power is regarded as the principal means of ensuring state stability and the continuity of its foreign policy.[5]<\/a><\/p>\n

The theory also holds that states act according to their own interests as the primary determinant of their behavior. However, the definition of these interests is shaped by balances of power and relations with other states. There are no permanent friendships or enmities; rather, there are interests that change according to circumstances.<\/p>\n

From a realist perspective, power<\/strong> is understood as the embodiment of a state\u2019s ability to protect its interests, whether through military strength or elements of comprehensive national power, including geographic location, economic capabilities, and intangible resources.<\/p>\n

Realism further points to a set of supreme and enduring interests that constitute the strategic objectives of states, such as protecting the state from external threats, achieving sustainable economic development, enhancing political and social stability, and maintaining an influential international position that grants the state prestige and recognition.<\/p>\n

National interest is analyzed on two main levels: the state\u2019s national characteristics and decision-makers. It is defined through the objective capabilities of the state, but it is also shaped by the vision of political leadership and its ability to strategically and effectively employ instruments of power. In realist analysis, national interest is what decision-makers perceive and seek to achieve through state institutions, and these orientations may change with shifts in political leadership.<\/p>\n

Within this framework, realist theory will be employed to understand Iran\u2019s actions in the Strait of Hormuz, where the state seeks to maximize its power and enhance its security through control over one of the world\u2019s most important maritime chokepoints. Iran\u2019s use of the strait as an instrument of economic and political pressure in response to sanctions and international pressure is interpreted through the lens of national interest and deterrence, in line with the realist perspective on international relations.<\/p>\n

First: The Economic Importance of the Strait of Hormuz with respect to Iran<\/strong><\/h2>\n

The economic dimension of the Strait of Hormuz constitutes a fundamental pillar for understanding Iran\u2019s strategy, as the strait represents a vital artery for oil and gas exports and a key element in the structure of the Iranian economy. Accordingly, any disruption to maritime navigation or threat to the safety of shipping in the strait has a direct impact on Iran\u2019s revenues. Its effects are not confined to the domestic level but extend to causing widespread disruptions and volatility in global energy markets.[6]<\/a><\/p>\n

Iran recognizes that possessing a partial capacity to control or influence maritime traffic in the Strait of Hormuz is not merely a security lever, but essentially an instrument of economic pressure with international dimensions. This capability provides Iran with significant room for political maneuvering, as the threat of disrupting navigation or increasing maritime risk levels can be employed as a bargaining tool in its dealings with major powers, whether the United States, European countries, or Asian economies that heavily depend on energy flows through the strait. Thus, the strait transforms from a mere geographical passage into an active component in the equations of negotiation and economic deterrence.<\/p>\n

1 \u2013 The Importance of the Strait of Hormuz for Iranian Exports<\/strong><\/p>\n

A \u2013 The Degree of Dependence on the Strait<\/strong><\/p>\n

The vast majority of Iran\u2019s oil exports\u2014estimated at around 90 percent\u2014pass through the Strait of Hormuz. This makes the Iranian economy highly sensitive to any disruption in maritime traffic. Accordingly, even a temporary or partial disruption would directly affect the state\u2019s ability to generate oil revenues and would threaten one of the most important sources of financing for the Iranian economy.[7]<\/a><\/p>\n

B \u2013 Export Infrastructure<\/strong><\/p>\n

Kharg Island Port constitutes the backbone of Iran\u2019s crude oil exports, serving as the main gathering and export terminal, alongside several ports and facilities located along Iran\u2019s southern coastline. This geographical concentration of exports enhances the strategic importance of the Strait of Hormuz, while simultaneously increasing the level of risks associated with any security tensions in the region.[8]<\/a><\/p>\n

C \u2013 Economic Implications of Incidents and Disruptions<\/strong><\/p>\n

Any disruption to the Strait\u2014whether partial or total\u2014leads to immediate effects on global energy markets, most notably an increase in oil prices. However, such price hikes do not necessarily translate into gains for Iran, as they are often accompanied by a decline in actual export volumes, particularly under the framework of international sanctions. In this sense, the Strait becomes a double-edged sword: a tool of pressure on the global economy, while simultaneously constituting a structural vulnerability for the Iranian economy.[9]<\/a><\/p>\n

2 \u2013 The Impact of the Strait of Hormuz on Global Energy Markets<\/strong><\/p>\n

The Strait of Hormuz represents a strategic chokepoint in the global economic system, through which approximately 21 million barrels of crude oil and petroleum products pass daily, accounting for more than one-fifth of the world\u2019s energy needs. In the event of a disruption in flows\u2014even for a short period\u2014or if risks are sufficient to deter oil tanker operators from transiting the strait, markets experience rapid price increases and disruptions in global supply chains.[10]<\/a><\/p>\n

In such a scenario, major energy-importing countries are particularly affected, especially China, India, Japan, and South Korea, all of which rely heavily on oil and gas shipments from the Gulf via this maritime passage.[11]<\/a><\/p>\n

3 \u2013 Iran\u2019s Economic Strategy Related to the Strait<\/strong><\/p>\n

Iran\u2019s economic strategy relies on a set of policies aimed at maximizing the benefits of its geographical position adjacent to the Strait of Hormuz, including:<\/p>\n

A \u2013 Diversifying Export Routes<\/strong><\/p>\n

Tehran seeks to develop alternative ports and export terminals, such as the Port of Jask and others, in order to reduce its full dependence on the Strait of Hormuz in the event of crises.[12]<\/a><\/p>\n

B \u2013 Strengthening Infrastructure<\/strong><\/p>\n

Iran is working to upgrade its storage and export facilities to ensure the continuity of exports even during periods of heightened tensions.[13]<\/a><\/p>\n

C \u2013 Using the Strait as a Leverage Tool<\/strong><\/p>\n

Iran occasionally signals its willingness to use threats of disrupting maritime navigation or partially or fully closing the Strait as a bargaining instrument with major international powers. However, such a move is considered economically risky, given its impact on Iran\u2019s own economy as well as on the broader global energy system.<\/p>\n

4 \u2013 International Economic Dimensions<\/strong><\/p>\n

International relations are, in turn, significantly influenced by the location of the Strait of Hormuz. Control over the strait, or the ability to threaten maritime navigation through it, grants considerable influence over international energy and trade policies. Major powers consistently seek to ensure the security of this passage in order to avoid sharp increases in oil prices and a slowdown in global economic growth. This places Iran in a strategically important yet economically and politically risky bargaining position.<\/p>\n

From the above, it becomes clear that the economic dimension of the Strait of Hormuz represents a strategic pillar for Iran. It is not merely a transit route for oil exports, but also a tool of international influence and political leverage. Iran\u2019s economic strategies are directly linked to its ability to influence maritime traffic, diversify export routes, and secure the continuity of national revenues, in line with the principles of realist theory in international relations.<\/p>\n

Second: The Political Dimension of the Strait of Hormuz for Iran and Its Regional Influence Strategy<\/strong><\/h2>\n

The Strait of Hormuz is considered one of the world\u2019s most strategically important maritime passages, not only because of its vital role in energy transportation, but also due to its political and geopolitical significance in the interactions of regional and international powers. For Iran in particular, the strait occupies a central position within its political and security strategy, as it has been transformed into an instrument of influence and political leverage used in managing its confrontation with major powers and in reshaping regional balances of power in the Gulf and the Middle East.<\/p>\n

Iran does not view the Strait of Hormuz merely as a maritime transit route, but rather as a sovereign-political tool for maximizing its regional influence and compensating for imbalances in traditional power relations.<\/p>\n

1 \u2013 The Strait of Hormuz in Iranian Strategic and Political Thought<\/strong>
\nA \u2013 Geography as an Element of Political Power<\/strong><\/p>\n

Iran places great importance on geopolitics, and the Strait of Hormuz represents one of its most prominent examples. The strait lies within Iran\u2019s immediate geographical sphere of influence, and its southern coastline overlooks it, granting Iran both a real and perceived capacity to exert influence over it.<\/p>\n

In Iranian strategic thought, geography becomes a compensatory factor for relative deficiencies in economic and military power compared to the United States and its allies. This falls within the logic of asymmetric power, where geographical advantages are leveraged to offset structural imbalances in national capabilities.<\/p>\n

B \u2013 The Strait as Part of Iran\u2019s National Security<\/strong><\/p>\n

Iran officially links the security of the Strait of Hormuz to its national security and has institutionalized this approach in its military doctrines as well as in statements by its political and military leadership. It has repeatedly warned that any threat to Iran will be met with a corresponding threat to maritime security in the strait. This linkage aims to internationalize any potential conflict with Iran, preventing it from remaining confined to its geographic scope and instead extending it to encompass global energy interests.<\/p>\n

2 \u2013 The Strait of Hormuz as a Political Pressure Tool in Response to Sanctions<\/strong>
\nA \u2013 An Indirect Bargaining Instrument<\/strong><\/p>\n

In the context of U.S. and international sanctions, Iran has used the Strait of Hormuz as an indirect political leverage tool. It maintains a policy of \u201ccalculated ambiguity,\u201d keeping the possibility of disrupting maritime navigation open without explicitly declaring any intention to fully close the strait. This implicit threat gives Tehran the ability to increase the cost of sanctions on the international community by signaling potential global economic consequences, particularly for oil and gas markets.<\/p>\n

B \u2013 Responding to the \u201cMaximum Pressure\u201d Policy<\/strong><\/p>\n

During the U.S. \u201cmaximum pressure\u201d campaign, the Strait of Hormuz emerged as a political counter-tool. Iran linked the freedom of its oil exports to the freedom of international navigation, presenting this connection as a political message that depriving Iran of its economic rights would be met with threats to regional stability.[14]<\/a><\/p>\n

3 \u2013 The Strait in the Deterrence Equation with the United States<\/strong><\/p>\n

A \u2013 Political Deterrence Before Military Deterrence<\/strong><\/p>\n

Iran does not rely solely on military deterrence in its approach to the Strait of Hormuz, but also on political and psychological deterrence. The repeated discourse surrounding the strait is intended to influence the calculations of American decision-makers and shape their strategic assessments.<\/p>\n

B \u2013 Transforming the Conflict into an International Issue<\/strong><\/p>\n

The Strait of Hormuz enables Iran to transform any bilateral conflict with the United States into an issue of international security, given the global economy\u2019s dependence on the stability of navigation through the strait.<\/p>\n

4 \u2013 The Strait and Strengthening Iran\u2019s Regional Role in the Gulf<\/strong><\/p>\n

A \u2013 Imposing the \u201cNo Security Without Iran\u201d Equation<\/strong><\/p>\n

Iran seeks to establish a political equation based on the idea that Gulf security\u2014and the security of the Strait of Hormuz\u2014cannot be achieved without its participation. It rejects security initiatives that exclude it, aiming instead to position itself as an indispensable actor in any regional security architecture.<\/p>\n

B \u2013 Managing Relations with Gulf Cooperation Council States<\/strong><\/p>\n

The Strait of Hormuz plays a dual role in Iran\u2013Gulf relations, functioning both as a tool of political deterrence and as a channel for negotiation and the potential development of regional security arrangements.<\/p>\n

5 \u2013 The Strait of Hormuz within Iran\u2019s Broader Regional Influence Strategy<\/strong><\/p>\n

A \u2013 Integration with Indirect Influence<\/strong><\/p>\n

The political role of the Strait of Hormuz is integrated into Iran\u2019s strategy of expanding indirect influence through regional allies, thereby strengthening its negotiating position at the international level.<\/p>\n

B \u2013 The Strait as a Balancing Tool Against Competing Regional Powers<\/strong><\/p>\n

The Strait provides Iran with the ability to balance the influence of Saudi Arabia and the United Arab Emirates in the Gulf and to limit their political freedom of action in confronting Tehran.<\/p>\n

The Strait of Hormuz thus represents a cornerstone of Iran\u2019s political dimension within its strategic framework, as it is transformed into an instrument of influence and political deterrence used to impose recognition of Iran\u2019s regional role and enhance its bargaining position.<\/p>\n

Third: The Security and Military Dimension of the Strait of Hormuz for Iran<\/strong><\/h2>\n

The security and military dimension represents a fundamental element in Iran\u2019s strategy for safeguarding its national security and protecting its interests in the Gulf region. The Strait of Hormuz is not merely an economic passage; it is also a strategic stronghold that Iran partially influences through its military capabilities, enabling it to exercise regional and international deterrence.<\/p>\n

According to realist theory, Iran seeks to maximize its military power and control vital chokepoints to secure its interests, particularly within an imbalanced international system where power constitutes the primary guarantee of national security.<\/p>\n
