​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 2014 report shows:

• during the twelve months to December 2014 the All Items Retail Prices Index (RPI) for Jersey increased by 1.3% to stand at 158.5 (June 2000 = 100)
• the increase in the RPI over the twelve months to September 2014 was 1.9%; hence, the annual rate of inflation decreased by 0.6 percentage points in the latest quarter
• this latest decrease in the annual rate of inflation was due to several groups giving small downward contributions to the annual rate of increase of the RPI
• RPI(X) increased by 1.5% over the twelve months to December 2014 and underlying inflation as measured by RPI(Y) increased by 1.3% over the same period
• in the latest quarter, both RPI(X) and RPI(Y) recorded their lowest annual rates of increase for more than a year, since September 2013
• the annual rates of increase of RPI Pensioners and RPI Low Income over the twelve months to December 2014 were 0.9% and 1.4%, respectively; both indices recorded their lowest annual rates of increase since these measures were first published in 2007
