In brief: Jersey’s annual inflation rate has reached 3.0% in the year to September 2026, according to figures from Statistics Jersey. The Retail Prices Index, which includes housing costs, remains the island’s headline measure of the cost of living.
Inflation in Jersey
Figures from Statistics Jersey show that the Retail Prices Index (RPI) rose by 3.0% in the twelve months to September 2026. For Jersey households already navigating a famously expensive cost of living, the official inflation measure is unlikely to be welcome news.
The RPI is the island’s principal measure of price changes and covers the goods and services bought by Jersey households, including housing costs. Statistics Jersey also publishes two related measures: RPIX, which strips out mortgage interest payments, and RPIY, which removes indirect taxes such as GST and impôts to give a cleaner picture of underlying inflation. Separate indices track price pressures specifically for pensioner and low-income households, reflecting the fact that different groups spend their money in rather different ways.

What the figures mean for Jersey residents
A headline rate of 3.0% means that, on average, the basket of goods and services tracked by Statistics Jersey costs 3.0% more than it did a year ago. For a household spending, say, £3,000 a month, that represents an additional £90 a month simply to stand still. In a jurisdiction where wages, rents and everyday costs already run well above UK levels, the cumulative effect of sustained inflation is felt keenly.
Jersey’s RPI has a long history: Statistics Jersey publishes annual average index numbers stretching back to 1949, providing a remarkable long-run record of how prices on the island have evolved over more than seven decades. The current 3.0% figure sits in a very different world from the double-digit rates of the 1970s and early 1980s, but it is nonetheless a reminder that the post-pandemic inflationary surge has not entirely unwound.
For pensioners and those on lower incomes, the dedicated sub-indices published by Statistics Jersey will be particularly relevant, since these groups tend to spend a higher proportion of their income on essentials such as food and energy, categories that have driven much of the inflationary pressure in recent years.
The broader context
Jersey sets its own monetary policy in some respects, but as a small, open economy closely tied to the United Kingdom, it has limited insulation from global and UK price trends. Imported goods, energy and food all carry external price signals that feed directly into the island’s RPI. The Government of Jersey’s fiscal decisions, including the rate of GST and impôts duties, also feed into the headline RPI figure, though RPIY is designed to filter those out for analytical purposes.
Statistics Jersey publishes the RPI quarterly, and the next release is due on 23 October 2026, covering the same September 2026 period, according to the NSFW data page.
