• during the twelve months to September 2018 the All Items Retail Prices Index (RPI) for Jersey increased by 4.3% to stand at 175.0 (June 2000 = 100)
• the Housing, Household services, Motoring and Leisure services groups were the largest contributors to the overall annual increase in the RPI
• a key driver in the Housing group was the increased cost of house purchase due to higher mortgage interest payments following the increases in the Bank of England base rate in November 2017 and August 2018
• the increase in the RPI over the twelve months to June 2018 was 4.5%; hence, the annual rate of inflation fell by 0.2 percentage points (pp) in the latest quarter
• the fall in the annual rate was largely due to Fares & other travel costs, which decreased over the year to September 2018, as well as lower rates of price increase for Motoring, Household services and Leisure goods over the year to September 2018 compared to the year to June 2018
