​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 March 2015 report shows:

• during the twelve months to March 2015 the All Items Retail Prices Index (RPI) for Jersey increased by 0.6% to stand at 158.9 (June 2000 = 100)
• the increase in the RPI over the twelve months to December 2014 was 1.3%; hence, the annual rate of inflation fell by 0.7 percentage points in the latest quarter
• key contributors to this fall in the annual rate of inflation were the cost of motoring, which decreased over the twelve months to March 2015, and the cost of Household services, which saw a lower rate of price increase over the twelve months to March 2015 than over the twelve months to December 2014
• RPI(X)  increased by 0.7% over the twelve months to March 2015 and underlying inflation, as measured by RPI(Y) , increased by 0.6% over the same period
• in the latest quarter, both RPI(X) and RPI(Y) recorded their lowest annual rates of increase since these measures were first published (in 2000 and 2007, respectively)
• the increase of RPI Low Income over the twelve months to March 2015 was 0.6%, the lowest annual rate of increase for this measure since it was introduced in 2007
• the change in RPI Pensioners over the twelve months to March 2015 was 0.1%, implying that retail prices for pensioner households were marginally lower on an annual basis​
