Introduction
Tariffs, traditionally used for revenue and protection, are increasingly deployed to secure strategic, technological and geopolitical objectives. Their growing use by major economies threatens the rules-based multilateral trading system centred on the World Trade Organization (WTO).
Use of Tariffs as Instruments of Pressure
- Domestic protection: Tariffs shield strategic industries and employment from import competition.
- Geopolitical leverage: Tariff threats are used to obtain concessions on trade, migration, security and market access.
- Strategic autonomy: Duties on semiconductors, steel, electric vehicles and critical minerals seek to reduce dependence on geopolitical rivals.
- Corrective action: Countries justify tariffs as responses to dumping, subsidies, technology transfers and market distortions.
Challenges to Multilateral Trade
- Erosion of WTO principles: Unilateral and discriminatory duties weaken non-discrimination, predictability and bound tariff commitments.
- Retaliatory protectionism: Counter-tariffs can escalate into trade wars, increasing consumer prices and production costs.
- Trade fragmentation: “Friend-shoring” and competing economic blocs disrupt global value chains.
- Weak dispute settlement: Paralysis of the WTO Appellate Body encourages action outside multilateral procedures.
- Impact on developing countries: Export uncertainty, trade diversion and higher input costs disproportionately affect smaller economies.
- Security exception: Its excessive invocation may create an unchecked escape from trade obligations.
Way Forward
- Restore the WTO’s two-tier dispute-settlement mechanism.
- Clarify limits on national-security exceptions.
- Strengthen rules governing industrial subsidies and non-tariff barriers.
- Promote plurilateral negotiations where universal consensus is difficult.
- Provide special and differential treatment to developing countries.
- Encourage consultation before imposing unilateral tariffs.
Conclusion
Strategic concerns are legitimate, but tariffs must remain transparent, proportionate and WTO-consistent. Reformed multilateralism is essential to reconcile national interests with stable and equitable global trade.
