What is Government debt % GDP?

Government debt % GDP, measured in %, measures the government's fiscal obligations and borrowing levels in Tonga, serving as a critical indicator of fiscal sustainability, creditworthiness, and the capacity to finance public services and respond to crises. Government debt accumulates when spending exceeds revenues over time, requiring borrowing from domestic and international creditors through bond issuance. In Tonga, Government debt % GDP is typically expressed as a percentage of GDP to account for the economy's capacity to service the debt — a country with larger economic output can sustain higher debt levels than a smaller economy. Key considerations include debt composition (domestic vs foreign currency, short vs long-term), interest rates, and who holds the debt (domestic investors, foreign governments, central banks). Sustainable debt levels vary by country depending on institutional strength, growth prospects, and investor confidence, but ratios above 90-100% of GDP often raise concerns among credit rating agencies.
