Sanctions & Economic Statecraft
Unilateral, UN, and secondary sanctions — with deep dives into the Iran and Russia cases.
Types
UN sanctions
Security Council imposes under Chapter VII. Binding on all 193 member states.
Key Points
- Current regimes: North Korea, Libya, Somalia, ISIL/Al-Qaida, and others.
- Sanctions committees monitor implementation and grant exemptions.
- Panel of Experts reports provide evidence of violations — NK panel disbanded 2024 after Russian veto.
Unilateral sanctions
Imposed by a single state or bloc without UN authorization.
Key Points
- US: Office of Foreign Assets Control (OFAC). Uses SDN list, sectoral sanctions, export controls.
- EU: CFSP decisions + implementing regulations. Consensus of 27 required.
- UK: post-Brexit Sanctions and Anti-Money Laundering Act 2018 regime.
- Most comprehensive unilateral regime historically: US on Cuba since 1960.
Secondary sanctions
Apply to third-country entities doing business with the sanctioned target.
Key Points
- US secondary sanctions on Iran use dollar-clearing and SWIFT access as leverage.
- European firms often withdraw from sanctioned markets to avoid US exposure even when EU doesn't sanction.
- EU Blocking Statute (Reg 2271/96) theoretically protects EU firms but rarely invoked.
Tools
Financial sanctions
Asset freezes
Target's funds in the sanctioning jurisdiction are immobilized. Applied to individuals on SDN list and to sanctioned states.
Banking restrictions
Target cut off from correspondent banking; unable to process dollar payments.
SWIFT disconnection
Removal from the global messaging system — applied to specific Iranian (2012, 2018) and Russian (2022) banks.
Trade sanctions
Key Points
- Export controls: dual-use items, weapons, sensitive tech (Wassenaar Arrangement).
- Import bans: on goods from sanctioned entities.
- Sectoral sanctions: target specific industries (e.g., Russian oil and gas).
- Technology denial: US chip restrictions on China (Oct 2022, Oct 2023 expanded).
Travel + visa bans
Often paired with asset freezes on named individuals. Magnitsky-style sanctions (US, UK, EU, Canada) target human rights abusers specifically.
Case Studies
Iran sanctions
The most studied modern sanctions regime — 1979 hostage crisis onward, intensified around the nuclear program.
Key Points
- UN sanctions 2006-2015 (resolutions 1737, 1747, 1803, 1929).
- JCPOA (2015): major sanctions relief in exchange for nuclear limits.
- US withdrawal (2018): snapback of US sanctions, secondary enforcement intensified.
- Current status: heavy sanctions; Iran's oil exports drop and recover based on enforcement intensity.
Russia sanctions (2022-present)
The most comprehensive sanctions regime ever imposed on a G20 economy — in response to the invasion of Ukraine.
Key Points
- Asset freeze on $300B+ in Russian central bank reserves.
- SWIFT disconnection of major Russian banks.
- G7 oil price cap ($60/barrel) from December 2022.
- Export controls on chips, machinery, dual-use goods.
- Secondary enforcement targeting third-country shipments continues expanding.
Effectiveness Debate
Do sanctions work?
Hufbauer, Schott, Elliott (Peterson Institute) built the canonical dataset. Their review: sanctions 'succeed' (at least partially) in ~34% of cases. Critics argue the criteria are loose; defenders cite recent successes (Libya 2003, Iran 2015).
Key Points
- More effective on smaller, democratic, US-aligned targets.
- Less effective on authoritarian regimes with elite insulation.
- Most effective when multilateral, targeted, and paired with credible diplomatic offers.
Unintended costs
Key Points
- Humanitarian: Iraq 1990s sanctions are the classic cautionary tale (estimated 100,000s of excess deaths).
- Dollar weaponization: BRICS states actively exploring alternatives. China's CIPS payment system growing.
- Enforcement fatigue: US OFAC compliance costs rising; secondary enforcement straining European firms.
FAQ
What are 'smart sanctions'?
Targeted measures aimed at specific individuals or sectors rather than whole populations. Developed in response to humanitarian critiques of 1990s Iraq-style comprehensive sanctions. Most modern sanctions are 'smart.'
Are humanitarian goods exempt?
Usually yes — UNSC Res 2664 (2022) created a standing humanitarian carve-out for all UN sanctions regimes. National regimes often have parallel exemptions but implementation friction remains a real problem for NGOs.
