The Effectiveness Of Sanctions On Iran: A Deep Dive
For decades, economic sanctions have been a cornerstone of international diplomacy, frequently deployed as a non-military tool to influence the behavior of nations. Among the most prominent and persistently sanctioned countries is Iran, a nation that has faced an intricate web of restrictions for over forty years. The fundamental question, however, remains: what is the true effectiveness of sanctions on Iran, and do they achieve their intended goals?
This article delves into the complex history and multifaceted impact of sanctions imposed on Iran, exploring their economic consequences, their influence on Iran's strategic decisions, and the broader implications for international relations. By examining various perspectives and available data, we aim to provide a comprehensive understanding of whether these powerful economic measures truly deliver the desired behavioral change or merely lead to unintended consequences.

The Rise of Sanctions as a Policy Tool
In the realm of international relations, the use of economic sanctions has witnessed an exponential surge. The U.S. Treasury Department, for instance, estimated a staggering 900% increase in sanctions over the past two decades. This dramatic rise underscores a global trend: sanctions are increasingly viewed as a preferred alternative to armed conflict, a less costly and less destructive means to enforce behavioral change. Nations and international bodies deploy them to combat terrorism, to discourage regimes or individuals from acting in ways condemned by the international community or individual nations, and to promote adherence to international norms. Yet, despite their widespread application, the burning question is—how effective are these sanctions in achieving their desired outcomes?

The continuum towards more comprehensive sanctions has been a defining feature of foreign policy, particularly in cases where direct military intervention is deemed too risky or politically unfeasible. This shift reflects a strategic pivot towards economic warfare, aiming to cripple a target nation's financial and trade capabilities to compel a change in its policies. The underlying assumption is that sufficient economic pressure will force a government to reconsider its actions, whether it's developing weapons of mass destruction, supporting terrorism, or violating human rights. However, the practical application of this theory, especially concerning the effectiveness of sanctions on Iran, often reveals a far more complex reality than simple cause-and-effect.
A History of Sanctions on Iran
Iran stands as one of the most heavily sanctioned countries globally, with a history of restrictions dating back to the Iranian Revolution in 1979, when the United States first imposed unilateral sanctions. These initial measures were a response to the hostage crisis and the broader geopolitical shifts following the revolution. Over the decades, this initial set of measures evolved into an array of overlapping and increasingly comprehensive sanctions, targeting various sectors of Iran's economy, including its oil industry, financial institutions, and access to international trade. The focus of this paper is on the array of overlapping sanctions imposed on Iran, which have intensified significantly over time.
This paper surveys the literature on the economic effects of sanctions on Iran, with a principal focus on those imposed after 2006. This period marks a crucial phase, as international concerns over Iran's nuclear program escalated, leading to the imposition of multilateral sanctions by the United Nations and the European Union, in addition to continued unilateral measures by the U.S. The sheer volume and complexity of these restrictions make Iran a unique case study in understanding the long-term impact of economic pressure. The effectiveness of sanctions as an instrument of deterrence of unethical policies, as well as its consequences on the target countries, has attracted researchers' interest in both economics and political science. The existing literature mostly tries to study the success or failure of the sanctions and their effects on the targeted economies, providing a rich, albeit often conflicting, body of evidence regarding the efficacy of these measures on Iran.
Economic Fallout: The Immediate Impact
The immediate and tangible impact of sanctions on Iran's economy has been undeniable and severe. The primary objective of many sanction regimes is to inflict economic pain, thereby compelling a change in policy. In Iran's case, this objective has certainly been met in terms of economic contraction and financial hardship, affecting various facets of the nation's financial health and the daily lives of its citizens. The comprehensive nature of these economic sanctions, imposed by the United States and partner nations, has undeniably caused significant disruption, leading to a negative assessment of their effectiveness in achieving desired political outcomes.
GDP Contraction and Currency Devaluation
The International Monetary Fund (IMF) reported a significant contraction in Iran's Gross Domestic Product (GDP) as a direct consequence of the intensified sanctions. As a result of the sanctions, Iran's gross domestic product (GDP) contracted an estimated 4.8% in 2018 and was forecast to shrink another 9.5% in 2019, according to the International Monetary Fund. This severe economic downturn is a clear indicator of the immediate pressure exerted by the sanctions, reflecting reduced oil revenues, limited foreign investment, and disruptions to trade. Beyond GDP, Iran's rial/USD exchange rate has been a key indicator of economic distress, with the national currency experiencing substantial depreciation. This devaluation directly impacts purchasing power, fuels inflation, and erodes the savings of ordinary citizens, contributing to widespread economic anxiety and hardship. The financial instability created by these measures is profound, affecting everything from import costs to the cost of living for millions.
Oil Exports and Money Supply
To precisely identify the economic repercussions, researchers have augmented a structural vector autoregressive (SVAR) model of the Iranian macroeconomy with a sanctions intensity variable. This sophisticated analytical approach allows for the identification of short-run and long-run effects of sanction shocks on critical economic indicators. The model examines impacts on oil export revenues, Iran's rial/USD exchange rate, money supply growth, inflation, and output growth, while controlling for foreign output growth and other global factors such as global equity market fluctuations. The findings consistently highlight significant impacts on oil export revenues, which are vital for Iran's economy, as well as on money supply growth and inflation. The disruption to oil sales, a primary source of national income, directly translates into reduced government revenue, limits foreign currency reserves, and exacerbates economic instability. The overall picture painted by these economic indicators is one of a nation under immense financial strain, directly attributable to the pressure of sanctions.
Unintended Consequences and Strategic Shifts
While sanctions undoubtedly inflict economic damage, their ability to induce desired behavioral change is often debated, especially concerning the effectiveness of sanctions on Iran. One significant outcome identified from the study is that if the goal of sanctions is defined as purely instrumental terms, their effectiveness is indeed limited. Instead of compliance, sanctions can trigger unforeseen strategic shifts within the target country, leading to outcomes that were not initially intended by the sanctioning powers. This often involves a reorientation of economic priorities and a search for alternative pathways to national development and security, which can ironically undermine the very goals the sanctions aimed to achieve.
Fostering Self-Sufficiency
Paradoxically, the implementation of U.S. sanctions, particularly those imposed unilaterally, has inadvertently expedited Iran's journey towards self-sufficiency and reduced its dependency on the U.S. and Western nations for trade and imports. From an overwhelming 80% of imports prior to the revolution and sanctions that Iran relied on U.S. and Western allies to supply, there was a substantive decrease to about 63% in the years which followed the revolution. This dramatic shift indicates that instead of crippling Iran's economy into submission, sanctions pushed it to diversify its trade partners and develop domestic capabilities. Industries that once relied heavily on foreign components or expertise were forced to innovate and produce locally, fostering a degree of economic resilience. This adaptation, while painful in the short term, ultimately serves to undermine the long-term effectiveness of sanctions by making the Iranian economy less vulnerable to external pressure from traditional Western powers.
Forging New Alliances
The diminishing effectiveness of sanctions is a tangible reality, evident in Iran’s foreign trade statistics, oil sales, and the experiences of countries like Russia. When traditional economic partners are restricted, sanctioned nations are compelled to seek out new alliances and circumvent existing restrictions. This dynamic has created opportunities for Iran to forge partnerships with these countries, thereby undermining the effectiveness of sanctions. Sanctions against Iran, Russia, Afghanistan, China, and Venezuela have all made the news in recent weeks, highlighting a pattern of nations under pressure seeking common ground. This network of economic partners or circumvention mechanisms allows sanctioned states to continue trade, albeit often at a higher cost or through less transparent channels, thereby mitigating the intended isolation. The very act of isolating Iran has, in some cases, pushed it closer to other nations facing similar pressures, creating a bloc of countries less susceptible to Western influence and further challenging the overall effectiveness of sanctions.
The Nuclear Program: A Persistent Challenge
Despite the immense economic pressure, a critical assessment of the effectiveness of sanctions on Iran reveals a significant shortfall in achieving one of their primary objectives: halting Iran’s nuclear program. In Iran’s case, economic sanctions have not stopped Iran’s leaders from moving forward with a nuclear program. This outcome is a central argument presented in "How Sanctions Work," a collaborative history and monograph that outlines the comprehensive economic sanctions imposed by the United States and partner nations with ultimately a negative assessment of their effectiveness in achieving desired outcomes in Iran. The book is also an argument against enduring economic warfare, as exemplified by the Iranian experience, highlighting that even under severe duress, the leadership has maintained its strategic priorities.
Iran’s leadership has acknowledged as much. As Ayatollah Ali Khamenei, the country’s supreme leader, explained in September 2015, "[w]e negotiated so that the sanctions framework will be..." This statement suggests that while Iran was willing to negotiate on the terms and scope of sanctions, it was not necessarily willing to abandon its core strategic objectives, including its nuclear program. This persistent pursuit of nuclear capabilities, despite decades of crippling sanctions, raises fundamental questions about the ultimate utility of economic pressure as a sole means of deterrence. It suggests that for issues deemed existential or strategically vital by a regime, economic hardship, however severe, may not be enough to force a capitulation, thereby limiting the overall effectiveness of sanctions in achieving their most ambitious goals.
Unilateral vs. Multilateral Sanctions
The nature of sanctions—whether imposed by a single nation or multiple—plays a crucial role in their potential effectiveness. Multilateral sanctions are inherently more challenging for the target country to evade and create stronger economic pressure due to their broader reach. When numerous countries and international bodies participate in a sanctions regime, the avenues for circumvention are significantly reduced, and the economic impact is amplified. The collective pressure from multiple sources, including the United Nations, the European Union, and individual countries like the United States, exemplifies the effectiveness of multilateral sanctions. These sanctions were imposed by the United Nations, the European Union, and individual countries like the United States, creating a formidable barrier to Iran's international trade and financial transactions.
For instance, UN sanctions against Iran were more effective in inducing negotiations due to the broad international support they garnered. This widespread consensus and participation made it far more difficult for Iran to find alternative markets for its oil or secure essential imports, thereby increasing the leverage of the sanctioning powers. This contrasts sharply with unilateral sanctions imposed on Iran by the USA dating back to the Iranian revolution in 1979, which can be more easily circumvented by the target country finding alternative trading partners or illicit networks. While unilateral sanctions can still inflict pain, their overall impact and the desired behavioral change are often limited compared to a globally coordinated effort. The distinction highlights that the strength of a sanctions regime lies not just in its severity, but critically, in the breadth of its international backing.
Challenges in Measuring Effectiveness
Assessing the true effectiveness of sanctions is a complex undertaking, fraught with methodological difficulties. Federal agencies often do not conduct comprehensive assessments that precisely measure how effective sanctions are in meeting U.S. policy goals. This lack of systematic evaluation makes it challenging to draw definitive conclusions about their success or failure. Several factors contribute to these challenges: difficulties in isolating sanctions’ effects from other factors, shifting policy goals and objectives, and the lack of reliable data. For instance, economic downturns might be attributed solely to sanctions when global commodity prices or domestic policy missteps also play a significant role. Similarly, policy goals can evolve over time, making it hard to measure success against a moving target.
Researchers surveying the literature on the economic effects of sanctions on Iran, particularly those imposed after 2006, frequently discuss the inherent difficulties in isolating the impacts of sanctions from other global or domestic economic variables. The existing literature mostly tries to study the success or failure of the sanctions and their effects on the targeted economies, but often acknowledges these limitations. This makes a definitive, quantitative assessment of their success or failure particularly elusive. Without clear metrics and comprehensive data, it becomes challenging for policymakers to determine whether sanctions are achieving their intended purpose or if alternative strategies might be more effective. The complexity of the global economy and geopolitical landscape means that attributing specific outcomes solely to sanctions is often an oversimplification, further complicating the assessment of their true effectiveness.
Humanitarian Impact and Ethical Considerations
Beyond the geopolitical and economic considerations, the humanitarian consequences of comprehensive sanctions on Iran are a critical, often overlooked, aspect. Sanctions cause significant financial hardships to access healthcare services in Iran. Numerous studies and reports (17, 19, 26, 37) highlight how these restrictions impede the import of essential medicines, medical equipment, and raw materials for domestic pharmaceutical production. The outcomes are more severe for those in marginalised and vulnerable groups (16, 17, 19, 26, 32), who may lack the financial means or connections to navigate the complex and often illicit channels required to obtain necessary treatments. Regarding the effects of sanctions on a broader socioeconomic status, many scholars documented the harmful effects on Iran, indirectly.
These indirect harmful effects manifest in various ways, from increased poverty and unemployment to a decline in public services and overall quality of life. The argument against enduring economic warfare, as exemplified by the Iranian experience, often centers on these profound human costs. While the stated goal of sanctions is to compel behavioral change from a regime, the reality is that they often inflict widespread suffering on innocent civilians who have no control over their government's policies. This raises profound ethical questions about the collateral damage inflicted on innocent populations when sanctions are employed as a tool of statecraft. It compels a critical examination of whether the ends justify the means, especially when the primary policy goals, such as halting the nuclear program, remain unachieved, while the humanitarian crisis deepens. The long-term societal and health impacts of these measures can be devastating, creating lasting grievances and potentially fueling instability rather than promoting desired changes.
In conclusion, the effectiveness of sanctions on Iran presents a nuanced and often contradictory picture. While they undeniably inflict severe economic hardship, leading to significant GDP contraction and currency devaluation, their ability to fundamentally alter Iran's strategic trajectory, particularly regarding its nuclear program, appears limited. Instead, sanctions have often prompted Iran to pursue greater self-sufficiency and forge new international alliances, inadvertently diminishing their long-term leverage. The distinction between unilateral and multilateral sanctions is crucial, with the latter proving more impactful due to broader international support. However, the inherent challenges in measuring their precise effectiveness, coupled with the undeniable humanitarian costs, compel a critical re-evaluation of sanctions as a primary foreign policy instrument. As the global landscape continues to evolve, a more comprehensive and ethically informed approach to international pressure may be necessary to achieve desired outcomes without disproportionately harming civilian populations.
