The post-Cold War era was marked by the rise of globalization, characterized by free trade, open borders, multilateralism, and liberal internationalism. However, in recent years, this global integration is losing momentum due to economic inequality, geopolitical tensions, cultural backlash, and technological disruption.

As a result, the world is witnessing a resurgence of sovereign nationalism where states prioritize national interests, borders, and identities over global cooperation.

The Shift From Globalization to Nationalism

Waning of Globalization

1. Surge in trade barriers: The WTO reports that new trade-restrictive measures impacted a massive $887.7 billion of global trade in 2024.
2. Weaponized supply chains: Nations are restricting critical exports to stunt geopolitical rivals, such as China limiting gallium and graphite shipments.
3. Paralyzed multilateralism: Countries bypass global trade laws by invoking the National Security Exception under GATT Article XXI, rendering international dispute settlements ineffective.
4. Capital decoupling: Foreign Direct Investment is fracturing ideologically, with the IMF warning this could reduce worldwide GDP by 2.3%.
5. Return of explicit tariffs: The G20 Trade Policy Factbook 2025 highlights a widespread revival of aggressive, direct tariff barriers among major economies.

Rise of Sovereign Nationalism

1. State-led industrial policy: Nations aggressively localize manufacturing, visible in the US CHIPS and Science Act aiming for semiconductor supremacy.
2. Green protectionism: Environmental mandates are leveraged for economic nationalism, seen in the EU's Carbon Border Adjustment Mechanism (CBAM) penalizing developing imports.
3. Digital sovereignty: States erect virtual borders to protect citizen data, reflected in India's stringent data localization regulations.
4. Strategic autonomy: Nations prioritize domestic needs over bloc politics, illustrated by India securing discounted Russian oil despite Western pressure.
5. Defense indigenization: Governments mandate local sourcing to reduce vulnerabilities, seen in India's Atmanirbhar Bharat defense procurement quotas.

This shift requires recalibrating toward strategic interdependence. Middle powers like India must champion a reformed multilateralism that balances sovereign developmental needs with global supply chain resilience.
