The Consumer Price Index (CPI) is published monthly by the Tonga Statistics Department (TSD). It is the official measure of annual and monthly inflation in Tonga. It tracks the changing prices of a fixed basket of goods and services purchased by households, reflecting their overall expenditure patterns. The CPI 2021 report is used by the line ministries and the National Reserve Bank of Tonga (NRBT) to monitor price trends, evaluate inflationary pressures, and inform fiscal and monetary policy decisions to ensure economic stability.
In 2025, the TSD rebased the CPI using HIES 2021 expenditure data to ensure it accurately reflects current consumption patterns. The rebase exercise helped update the weights and increased the CPI 2021 basket by 46 new products. The old CPI 2018 basket contained 137 items, and the new CPI 2021 basket has 161 items. Some of the new items include green coconuts, cheese, cell phones, and cars, while excluding items with low expenditure shares like turkey tails and domestic call bundles.
