PNN – Strategic geography, regional economic ties, and sanctions-related constraints make it difficult for Washington to achieve its objective regarding Tehran.
On August 24, 2026, the Donald Trump administration announced the launch of an economic campaign against Iran dubbed “Operation Economic Ostracism,” stating that its goal was to sever Iran’s financial and trade links with the world and eliminate the channels through which Tehran generates revenue, sells oil, and conducts economic transactions.
Upon announcing this operation, U.S. Treasury Secretary Scott Bessent stated that Washington’s goal is to sever all of Iran’s economic lifelines, ultimately leaving the country isolated. The U.S. Treasury Department also announced the expansion of sanctions targeting financial networks, intermediary companies, oil transport fleets, and foreign entities collaborating with Iran.
This policy rests on the fundamental premise that if Iran’s access to revenue sources, banking networks, transport routes, and trading partners is sufficiently restricted; the resulting economic pressure could lead to political isolation and, ultimately, a change in Tehran’s behavior.
However, the gap between exerting economic pressure and achieving such an outcome is far too wide to be overlooked simply by announcing new sanctions or expanding the list of targeted companies. While sanctions may raise the cost of trade, reduce foreign currency revenues, and hinder business access to technology and capital, none of these consequences—in and of themselves—equate to a complete severance of a country’s economic ties with its surrounding region and the global economy.
Geographically, economically, and regionally, Iran occupies a position that presents serious obstacles to the implementation of a policy of total isolation. These obstacles do not imply that Iran is immune to economic pressure; rather, they illustrate why transforming such pressure into comprehensive isolation would require controlling a vast network of relationships, routes, intermediaries, and economic interests—a significant portion of which lie beyond the direct territory and control of the United States.
Geography That Limits the Possibility of Excluding Iran from Regional Equations
The most significant difference between Iran and a country that could be isolated by severing a few trade routes or restricting a handful of economic partners lies in its geographical location. Iran is situated at the nexus of several key geopolitical regions: the Persian Gulf and the Sea of Oman to the south, the Caspian Sea to the north, the Caucasus and Anatolia to the northwest, Central Asia to the northeast, and the Indian Subcontinent to the east. This position integrates Iran into the connectivity landscape linking the Middle East, Central Asia, and South Asia, as well as the trade routes spanning from east to west.
Iran shares borders with the Caucasus nations and the Caspian Sea to the north and northwest, Afghanistan and Pakistan to the east, Turkey and Iraq to the west, and Turkmenistan to the northeast. To the south, its extensive coastline provides access to the Persian Gulf and the Sea of Oman.
This combination of land and maritime borders creates a network of potential routes for regional trade, transportation, and connectivity. Consequently, isolating Iran entails far more than merely halting the flow of goods through a few ports or blocking specific banking channels; achieving such an objective would require the simultaneous restriction of maritime, land, financial, and commercial links across multiple geographic regions.
The significance of this matter becomes clearer when we view geography not merely as a natural advantage, but as an infrastructure for the formation of mutual interests. Iran’s neighbors face a range of geographical choices and constraints regarding the procurement of goods, market access, energy exports, transit, and connectivity with other regions.
In some instances, a route passing through Iran may be crucial in terms of distance or accessibility to a destination; in others, competing routes traverse the territories of neighboring countries. Consequently, Iran’s strategic position implies that excluding the country from regional connectivity networks is not merely a political decision; such a move could also entail economic and logistical costs for other nations.
This reality imposes a structural limitation on sanctions policy. While Washington can target a specific shipping company, bank, or oil buyer, achieving the complete isolation of Iran requires preventing the formation or continuation of alternative networks—connections that might be established through intermediaries, regional markets, various ports, overland routes, and non-dollar financial mechanisms. The more extensive a country’s network of connections and the more diverse its potential partners, the harder it becomes to transform targeted sanctions into a total severance of ties.
The Strait of Hormuz: Iran’s Importance Extends beyond Its Own Oil Exports
One of the clearest examples of Iran’s geopolitical significance is its location adjacent to the Strait of Hormuz; this waterway connects the Persian Gulf to the Sea of Oman and, subsequently, the Indian Ocean. The strait is crucial because a significant portion of other nations’ energy trade passes through it. Consequently, the strategic importance of this passage is not limited to bilateral trade relations between Iran and the United States but is directly linked to the energy security of the world’s major economies.
According to data from the U.S. Energy Information Administration, an average of 20.9 million barrels per day of crude oil, condensate, and petroleum products passed through the Strait of Hormuz during the first half of 2025; this volume is equivalent to approximately one-fifth of global petroleum liquid consumption and nearly one-quarter of global seaborne oil trade. Furthermore, about 89 percent of the crude oil and condensate passing through the strait during that period was destined for Asian markets. China, India, Japan, and South Korea were the combined destinations for approximately 74 percent of this oil flow.
These figures demonstrate that the geography surrounding Iran is intertwined with the economic interests of major powers, particularly Asian nations. Any policy leading to a sustained disruption of this corridor—or a sharp increase in transport risks within it—could impact energy costs, marine insurance, shipping, and commodity prices across various economies. In other words, Iran is situated adjacent to a strategic chokepoint with security and economic implications that extend well beyond national borders.
A more significant analytical point is that the importance of this waterway transforms the effort to exert pressure on Iran from a purely bilateral issue into a matter with regional and global implications. A country situated alongside such a chokepoint cannot simply be excluded from the region’s energy and security equations.
This interdependence creates a contradiction for the policy of “economic exclusion.” The United States seeks to curtail Iran’s economic ties, yet pursuing this objective takes place in a context where energy security and the continuity of maritime trade are of vital importance to many other nations.
These countries may disagree with Tehran’s regional policies while simultaneously being interested in maintaining the stability of energy routes, reducing trade costs, and preventing supply chain disruptions. Therefore, their decisions regarding economic cooperation with Iran are not shaped solely by Washington’s political stance; their own economic interests and security calculations also play a role.
Iran at the Crossroads of Land and Sea Routes
Iran’s geographical significance extends beyond the Strait of Hormuz. Its location—situated among the Persian Gulf, Central Asia, the Caucasus, and the Indian subcontinent—positions it as a potential transit hub connecting these diverse regions. Iran’s southern ports offer access to open waters, and—given the necessary infrastructure and coordination—the country’s road and rail networks could facilitate the transport of goods between south and north, or east and west.
This position holds particular significance for landlocked countries. Central Asian nations require a network of rail, road, port, and customs routes to access global markets. Iran represents a key geographical option for connecting these countries to open waters and the markets of South Asia. Similarly, Iran’s connections with Turkey and Iraq can facilitate trade between the Middle East and regions further west.
From this perspective, the operation of economic exclusion faces a complex challenge. Restricting one route may divert trade to another, drive up costs, or introduce new intermediaries into the supply chain, yet it does not necessarily halt trade altogether. For pressure on a specific route to result in a complete severance of economic ties, the capacity of alternative routes must also be constrained, or the cost of using them must rise to a level that trading partners can no longer bear. To completely sever Iran’s economic ties, the United States must block not only direct trade routes but also alternative channels for the movement of goods and commercial exchanges via neighboring countries—a task far more complex than sanctioning a specific company or entity, given the multitude of Iran’s borders, transport routes, and potential trading partners.
Why can’t Iran’s neighbors be excluded from economic equations solely through pressure from Washington?
Geography reveals its true significance when it intersects with the economic interests of surrounding nations. Iran is situated next to countries that meet a portion of their trade or energy needs through ties with it, while also maintaining relationships with major economic powers like China. Consequently, a policy of isolating Iran can only lead to a widespread severance of economic ties if these nations are willing to bear the cost of abandoning their relationships with Iran.
Iran’s foreign trade statistics indicate that these connections were not limited to just a few exchanges or a single trade route. According to customs data published by Al Jazeera in August 2026, Iran exported approximately $56 billion worth of goods to at least 112 countries and regions in 2024. China, with about $14.6 billion, and Iraq, with around $11.7 billion, were among Iran’s key export destinations; Turkey and Afghanistan were also counted among its major partners.
China offers a clearer example of the limitations of U.S. economic pressure policies. Despite Washington’s sanctions, China has continued to purchase Iranian oil in recent years. Estimates from Columbia University’s Center on Global Energy Policy indicate that in 2025, China imported approximately 1.38 million barrels of Iranian oil per day—a volume that constituted a significant portion of Iran’s seaborne crude oil exports. Part of this trade is conducted via routes that are not recorded in official Chinese customs statistics as imports from Iran.
Therefore, although U.S. sanctions increase the costs of selling Iranian oil, limit the pool of buyers, and compel Tehran to utilize more complex shipping and payment networks, China’s continued purchase of Iranian oil demonstrates that U.S. economic pressure does not necessarily lead to a severance of ties with all of Iran’s key partners—particularly when a country retains an economic incentive to secure its energy supplies and is willing to shoulder some of the costs of cooperation in the face of pressure from Washington.
China and the Limitations of Efforts to Cut off Iran’s Oil Revenues
China holds a special place among Iran’s economic partners. In recent years, the Chinese market has been a primary destination for Iran’s oil exports. This relationship demonstrates that the policy of economic isolation faces a challenge extending beyond mere geography; the U.S. government must find a way to influence the economic decisions of an actor that possesses its own independent energy and commercial interests while simultaneously pursuing a broader strategic rivalry with Washington.
In a report issued in November 2025, the U.S.-China Economic and Security Review Commission stated that China has emerged as a major buyer of Iranian oil, with a network of independent refineries, intermediary firms, and transport and payment mechanisms facilitating the trade.
Citing its own estimates alongside data from other institutions, the report highlights China’s substantial share in the purchase of Iran’s oil exports and explains that a portion of this trade is conducted through intermediaries and complex documentation regarding the oil’s origin. While these figures must be interpreted with caution—given the limitations of official data and the difficulty of tracking sanctioned shipments—the evidence collectively indicates that U.S. pressure has thus far failed to completely eliminate foreign demand for Iranian oil.
The Resistance Economy as a Structural Response
However, geography alone does not explain why Iran has been able to effectively utilize these routes. A complementary factor is the set of policies formulated in Iran under the banner of the “Resistance Economy”—a systematic strategy designed to counter Western policies of pressure. This strategy focuses on reducing reliance on oil revenues, expanding non-oil exports, strengthening domestic production, and developing alternative payment systems.
The results of this approach are evident in the statistics. Iran’s non-oil exports reached approximately $58 billion during the period from March 2024 to March 2025. These exports maintained their upward trend despite political pressures and the activation of the sanctions mechanism known as the “snapback” (or “trigger”) mechanism; meanwhile, the country’s foreign trade—leveraging regional and neighboring markets—embarked on a path of sustainable growth.
Pivot to the East
Geography and the “Resistance Economy” operate within the context of a broader geopolitical shift known as Iran’s pivot to the East. The 25-year agreement with China and the 20-year agreement with Russia are the two pillars of this pivot.
According to analysts, these agreements—spanning the energy, transport, technology, and financial sectors—could “neutralize a significant portion of sanctions-related restrictions.” Iran and Russia have linked their respective financial messaging systems—SEPAM and SPFS—and eliminated the US dollar from 90 percent of their bilateral transactions. Trilateral cooperation among Iran, China, and Russia, utilizing sanction-resistant trade routes, has created a network that operates independently of the SWIFT system and the US dollar.
These collaborations also have another dimension directly related to geography. Russia and Iran have transformed the Caspian shipping network into what officials call a “sanctions-busting corridor.” Approximately two million tons of Russian wheat reach Iran via the Caspian, and this entire supply route bypasses the Strait of Hormuz and the U.S. maritime cordon.
