Trade Openness by Country — 2025 World Rankings

Trade openness measures total trade (exports plus imports of goods and services) as a percentage of GDP. It captures how integrated a country is with the global economy. Higher values indicate greater dependence on international trade, while lower values suggest a more domestically oriented economy. The data comes from the World Bank's World Development Indicators.

Trade openness varies enormously by country size. Small, open economies like Singapore (trade exceeding 300% of GDP), Luxembourg, and Hong Kong are extremely trade-dependent — their domestic markets are too small to sustain the variety of production their economies support. Large economies like the United States (about 25% of GDP), China (about 37%), and Japan (about 35%) appear less open in percentage terms, but their absolute trade volumes are the largest in the world.

The relationship between trade openness and growth is one of the most studied topics in economics. The consensus is that trade liberalization generally accelerates growth through specialization, technology transfer, and competitive pressure — but the effects are not uniform. Countries that opened their economies while investing in education, infrastructure, and institutional quality (East Asia, Eastern Europe) benefited enormously. Countries that liberalized without these foundations sometimes experienced deindustrialization and rising inequality. The recent trend toward "friend-shoring" and supply chain diversification after the pandemic and geopolitical tensions represents a partial retreat from maximum openness.
