The appeal of sanctions is obvious: they promise to punish bad actors without the blood and treasure of military intervention. They are the foreign policy equivalent of grounding a misbehaving teenager—painful enough to matter, civilized enough to feel proportionate. Yet sanctions have a curious record of being simultaneously overused and underperforming, deployed with confidence and evaluated with disappointment.
The gap between expectation and outcome stems from a fundamental misunderstanding of what sanctions actually are and how they function. They are not a single instrument but a sprawling toolkit, and their effectiveness depends entirely on which tools are selected, who wields them, and whether the target has anywhere else to turn.
The anatomy of economic pressure
Modern sanctions come in several distinct flavors. Asset freezes target specific individuals or entities, locking their foreign-held wealth in place. Trade restrictions prohibit the export or import of particular goods—weapons, luxury items, oil field equipment. Financial sanctions cut targets off from the global banking system, making it difficult to move money across borders. Comprehensive embargoes combine all of the above into near-total economic isolation.
The United States enjoys unique leverage in this arena because of the dollar's role as the world's reserve currency. Any transaction that touches the American financial system—which means nearly every significant international transfer—falls under U.S. jurisdiction. This gives Washington the power to impose "secondary sanctions," punishing not just the target but any third party that does business with the target. A European bank that processes payments for a sanctioned Iranian company can find itself locked out of the American market. This extraterritorial reach is what makes American sanctions so potent and so resented.
Why targets adapt faster than architects expect
Sanctions assume a static target, but targets are dynamic. When the West froze Russian central bank assets in 2022, Moscow accelerated its pivot toward yuan-denominated trade and alternative payment systems. Iran has spent decades building smuggling networks and front companies to evade restrictions. North Korea has become a case study in sanctions-resistant autarky, accepting economic misery as the price of regime survival.
The humanitarian critique is well-known: sanctions often hurt ordinary citizens while regime elites find workarounds. Less discussed is the political critique. Sanctions can entrench the governments they aim to weaken by providing a convenient external enemy to blame for economic suffering. They work best against countries that value integration into the global economy and worst against those willing to accept isolation.
The compliance industry nobody talks about
Behind every sanctions regime is a vast bureaucracy of enforcement. Banks employ thousands of compliance officers who screen transactions against constantly updated lists of sanctioned entities. Shipping companies track vessel movements to avoid carrying prohibited cargo. Law firms specialize in advising clients on what they can and cannot do. This compliance infrastructure is expensive, imperfect, and creates its own perverse incentives—banks sometimes "de-risk" by refusing to serve entire regions rather than invest in nuanced screening.
Our take
Sanctions persist because they occupy a comfortable middle ground between doing nothing and doing something dramatic. They allow politicians to appear tough without committing troops. But this convenience has bred overreliance. When every foreign policy problem looks like a nail, sanctions become the only hammer. The result is a world where the tool is losing its edge through overuse, where targets have learned to adapt, and where the collateral damage to civilians and to the rules-based economic order itself rarely enters the cost-benefit analysis. Sanctions work—sometimes, partially, eventually. The honest version of that sentence rarely makes it into the press release.
