Tonga’s economic freedom score is 63.1, making its economy the 76th freest in the 2018 Index. Its overall score has increased by 0.1 point, with significant improvements in fiscal health and judicial effectiveness offsetting lower scores for the government integrity, government spending, and property rights indicators. Tonga is ranked 17th among 43 countries in the Asia–Pacific region, and its overall score is above the regional and world averages.

Although the government hopes that Tonga’s small, open island economy will attract investment and develop a larger private sector, the dominance of the public sector thwarts economic dynamism, and institutional capacity is weak. The judicial system is inefficient and lacks transparency. A lack of commitment to fully open markets impedes investment growth. The state’s oversized role in the economy crowds out private-sector development. Despite improved oversight of government expenditures, Tonga’s public debt poses a challenge to fiscal sustainability.



The archipelagos of the Friendly Islands were united in 1845. The Kingdom of Tonga, the South Pacific’s last Polynesian monarchy, withdrew from British protection and became fully independent in 1970. The royal family, hereditary nobles, and a few other landholders control politics. Tonga held its first elections in 2010 under its newly formed constitutional monarchy. The Democratic Party of the Friendly Islands won a plurality in parliament, and Lord Siale’ataongo Tu’ivakano became Tonga’s first elected prime minister. In 2014 elections, the DPFI retained power but elected a new prime minister, ‘Akilisi Pohiva. The economy depends on agriculture (e.g., squash, vanilla beans, and yams) as well as tourism and fish exports. Emigrants’ remittances account for nearly one-third of GDP.

Rule of LawView Methodology

Property Rights 62.1 Create a Graph using this measurement

Government Integrity 40.5 Create a Graph using this measurement

Judicial Effectiveness 25.4 Create a Graph using this measurement

Enforcement of property rights is weak, and registration is inefficient. The judiciary is generally independent but poorly resourced. The law provides criminal penalties for official corruption, and the government seeks to implement the law effectively, but there continue to be reports of government corruption and occasional reports of officials engaging in corrupt practices with impunity.

Government SizeView Methodology

The top personal income tax rate is 20 percent, and the top corporate tax rate is 25 percent. Other taxes include value-added and interest taxes. The overall tax burden equals 20.8 percent of total domestic income. Over the past three years, government spending has amounted to 32.3 percent of total output (GDP), and budgets have been balanced. Public debt is equivalent to 45.1 percent of GDP.

Regulatory EfficiencyView Methodology

A dynamic private sector has still not emerged, partly because of the inefficient implementation of a statutorily business-friendly regulatory environment. The formal labor structure is undeveloped, and labor regulations are not enforced effectively. The government influences prices through subsidies for electricity and subsidies to loss-making state-owned enterprises.

Open MarketsView Methodology

Trade is significant for Tonga’s economy; the combined value of exports and imports equals 78 percent of GDP. The average applied tariff rate is 5.7 percent. Nontariff barriers impede some trade. Government openness to foreign investment is below average. The poorly developed legal system impedes the emergence of a modern financial sector. There are no capital markets. Only a small proportion of the population uses banking services.
