Share of World GDP: Tonga

Analysis# Tonga Share of World GDP Tonga's share of global economic output currently stands at 0% as of 2026, reflecting its status as a small island nation with minimal economic scale on the world stage. The country reached its all-time peak of 0.001% in 1980, before declining steadily over four decades. By 2010, Tonga's share had fallen to an all-time low of 0%, where it has remained flat through 2026—a total contraction of 100% since 1980. The decline accelerated significantly between 1980 and 2010, marking a period of relative economic stagnation for the island nation. Since 2010, Tonga's contribution to world GDP has remained negligible and unchanged. With projections extending to 2030 showing no recovery, the data indicates Tonga's share is unlikely to rebound substantially without transformative economic growth, remaining immeasurable at the global economic scale.
