Economic Sanctions: Theory and Practice

Economic Sanctions: Theory and Practice

Economic sanctions—restrictions on economic relations designed to compel a state or organization to change its behavior—have become one of the main tools of international politics. Trade embargoes, asset freezes, and financial restrictions are being applied more and more frequently. But how effective are sanctions?

Types of Sanctions

Comprehensive (all-encompassing) sanctions—a ban on all or most economic relations with a state. Historical examples: the embargo against Iraq from 1990–2003, against Cuba. Now rare due to humanitarian costs.

Targeted (“smart”) sanctions—restrictions aimed at specific individuals, companies, sectors. Freezing officials’ assets, travel bans, sectoral restrictions. In theory, they minimize harm to the population.

Financial sanctions—disconnection from the international financial system. The most powerful tool: disconnection from SWIFT, blocking of correspondent relations, prohibition of dollar transactions. Effective due to the centrality of the American financial system.

Trade restrictions—ban on the export or import of certain goods. Embargoes on oil, technology, weapons.

Theoretical Foundations

The logic of coercion. Sanctions inflict economic damage, creating costs for the target state. A rational government should change its behavior when the costs outweigh the benefits of continuing its policy.

The “sender-target” model. The sender is the state or coalition imposing sanctions. The target is the state or organization at which the sanctions are aimed. Success depends on their relative sizes, dependencies, and alternatives.

Costs for the sender. Sanctions are not costless. The sender loses trade and investment connections. Companies in the sender country suffer from lost markets. This limits the willingness to impose and maintain sanctions.

Empirical Results

Systematic studies (Hufbauer, Schott, Elliott) have assessed the effectiveness of sanctions:

Overall success—in about a third of cases. Approximately 30–35% of sanction episodes have led to (at least partial) achievement of goals. This is higher than is usually believed, but far from guaranteed success.

Conditions for success:

• Modest goals (changing a specific policy is easier than regime change)
• High dependence of the target on the sender
• Rapid imposition (before the target adapts)
• International coordination
• Democratic targets (more sensitive to economic damage)

Conditions for failure:

• Ambitious goals (regime change is rarely achieved)
• Authoritarian targets (regimes shift costs onto the population)
• Availability of alternative partners (a “lifeline” from China, Russia)
• Duration (adaptation, “rallying around the flag”)

Problems with Sanctions

Humanitarian consequences. Sanctions hit the population: shortages of goods, price increases, unemployment, deterioration of healthcare. Sanctions against Iraq, according to some estimates, contributed to the deaths of hundreds of thousands of people. “Smart” sanctions are intended to minimize these consequences but do not eliminate them entirely.

Rallying around the regime. External pressure may strengthen, rather than weaken, the regime. The population blames the “aggressor” rather than the government for hardships. The regime uses sanctions to repress the “fifth column.”

Adaptation and circumvention. Over time, targets find ways around sanctions: smuggling, intermediaries, cryptocurrencies, alternative financial systems.

Side effects. Sanctions affect third countries. Secondary sanctions (the threat of punishment for cooperating with the target) are especially controversial—this is the extraterritorial application of law.

Modern Examples

Iran. Years of sanctions inflicted serious economic damage. Led to the 2015 nuclear deal (JCPOA), but after the U.S. withdrawal (2018) and tightened sanctions, Iran resumed its nuclear program.

Russia. Sanctions after the annexation of Crimea (2014) and especially after the invasion of Ukraine (2022) are unprecedented in scale. Freezing of Central Bank reserves, disconnection of banks from SWIFT, embargo on energy carriers. Long-term consequences are still being assessed.

North Korea. Decades of sanctions have not stopped the nuclear program. The regime has adapted; China is a “lifeline.”

Political Economy of Sanctions

Sanctions are not only a tool of coercion, but also a political signal:

Domestic political pressure. Governments impose sanctions to “do something” in response to public outrage. Even ineffective sanctions may be politically necessary.

Symbolic function. Sanctions demonstrate condemnation, set “red lines,” and uphold norms. Their value lies not only in changing target behavior but also in signaling.

Alternative to war. Sanctions are a tool between diplomacy and military force. Even ineffective sanctions may be preferable to war or inaction.

Sanctions remain an imperfect but widely used tool. Political-economic analysis helps to understand their possibilities and limitations.
