Share of World GDP: Guinea-Bissau

Analysis# Guinea-Bissau Share of World GDP Guinea-Bissau currently accounts for 0.003% of global GDP in 2026, representing a substantial decline from its all-time peak of 0.004% in 1980. Over the past 46 years, the country's share has contracted by 25%, reflecting slower economic growth relative to global expansion. The all-time low of 0.003% occurred in 1998, though the metric has remained flat at this minimum level for nearly three decades. Since 2017, Guinea-Bissau's world GDP share has stabilized at 0.003%, suggesting the country has reached an equilibrium within the global economy. The extended plateau from 2017 through 2026 indicates neither significant recovery toward historical peaks nor further erosion. Without major structural economic reforms or sustained investment in productivity, Guinea-Bissau's marginal share of world GDP is projected to persist at current levels through 2030.
