Overview
Tonga's interest payments to revenue stood at 0.76% in 2025, a decline of +0.50pp from 2023. Based on recent trends, this figure is projected to reach 0.76% by 2025. Tonga ranked 105th globally.
Tonga’s interest payments to revenue have fallen sharply over the 12‑year span covered, dropping from a peak of 2.94 % in 2013 to 0.76 % in 2025, the lowest level recorded in the series and placing the kingdom at 105th globally. This decline reflects a sustained reduction in debt service relative to fiscal capacity, driven by a combination of modest borrowing, prudent fiscal management and modest growth in revenue collections. By 2025 Tonga’s ratio is comparable to that of Switzerland (0.82 %) and Norway (0.83 %), and lower than Samoa’s 0.59 %, suggesting that the Pacific nation has aligned its debt profile with high‑income benchmarks despite its smaller economy. The downward trajectory indicates that, absent a sudden surge in borrowing or a sharp contraction in revenues, Tonga is likely to maintain a low interest‑to‑revenue burden, supporting fiscal space for public investment and social spending.
