National Debt (% of GDP): Thailand

Analysis# Thailand National Debt (% of GDP) Thailand's national debt reached 66.7% of GDP in 2026, marking an all-time peak after three decades of fluctuation. The metric has surged dramatically from its historic low of 15.2% in 1996, representing a total increase of 338.8% over the 30-year period. Since the mid-1990s, Thailand's debt burden has grown substantially, more than quadrupling from its nadir. A critical inflection point occurred in 2020, when the ratio jumped to 49.4% from 41.1% the previous year, reflecting pandemic-era fiscal pressures. The upward trajectory has accelerated since then, climbing consistently from 58.3% in 2021 through 66.7% in 2026. Current projections indicate Thailand's debt-to-GDP ratio will continue rising, signaling ongoing fiscal challenges and reduced fiscal flexibility for future policy interventions.
