​The All Items Retail Prices Index (RPI) is the main measure of inflation in Jersey. It measures the change from quarter to quarter in the price of the goods and services purchased by an average household in Jersey.

The December 2015 report shows:

• during the twelve months to December 2015, the All Items Retail Prices Index (RPI) for Jersey increased by 0.9% to stand at 160.0 (June 2000 = 100)
• the increase in the RPI over the twelve months to September 2015 was 0.1%; hence, the annual rate of inflation increased by 0.8 percentage points in the latest quarter
• this latest increase in the annual rate of inflation was the result of most groups of the RPI giving small upward contributions to the annual rate of change
• RPI(X) increased by 1.0% and underlying inflation, as measured by RPI(Y), increased by 0.9% over the twelve months to December 2015
• the annual rates of increase of RPI Pensioners and RPI Low Income over the twelve months to December 2015 were 0.8 % and 1.1%, respectively
• the annual rates of increase of RPI(X), RPI(Y), RPI Pensioners and RPI Low Income were all higher in December 2015 than in September 2015
• on a calendar year basis, the annual average change of the RPI in 2015 was the lowest observed since this index has been produced for Jersey (since 1949); the annual average changes of the other price indices were also the lowest since these measures were first introduced
