What is CPIx? The Briefed consumer stress index, explained

CPIx is a consumer stress index built and maintained by Briefed for the UK and US. It is designed to answer a question that official statistics answer slowly and sentiment surveys answer misleadingly: how financially stretched are consumers right now? Rather than asking households how they feel, CPIx measures what they are actually doing with money, and it does so in near-real time rather than on a monthly lag.

What CPIx measures

CPIx combines a set of behavioural signals into a single index of consumer financial pressure. The components include the growth and composition of consumer credit, delinquency and arrears trends, real wage movements, labour-market conditions, retail and discretionary demand, savings rates, and the cost of essentials such as energy. The emphasis throughout is on behaviour and balance sheets, what households are borrowing, repaying, saving, and spending, rather than on how they describe their situation to a pollster.

The reason for that emphasis is that behaviour leads sentiment. Financial stress tends to show up in credit and repayment data first, in discretionary spending next, and in confidence surveys last. By the time a sentiment survey registers stress, the behaviour that caused it has usually been visible in the data for weeks.

How CPIx differs from ONS and GfK data

Official UK consumer data, from the ONS, and the widely cited GfK Consumer Confidence Barometer are valuable, but they measure different things from CPIx and on a different clock. ONS releases are authoritative but monthly and backward-looking by design. GfK measures sentiment: how a sample of households feel and whether they intend to make major purchases. Feelings and intentions are real data, but they are not the same as financial position, and the two can move in opposite directions, with confidence recovering while balance sheets quietly deteriorate.

CPIx is built to sit alongside those measures, not to replace them. It complements ONS and GfK by adding a faster, behaviour-based read, and it is most useful precisely when it diverges from the sentiment surveys, because that divergence has historically been an early signal that spending is about to move. We covered this gap in detail in our note on what the consumer confidence surveys are not measuring.

How to read it

CPIx is most informative as a direction and a divergence, not as a single headline number. A rising index means consumer financial pressure is building; the value is in watching the trend and in comparing it against the sentiment surveys and headline retail figures. When CPIx is climbing while confidence holds steady, the index is flagging stress that the surveys have not yet caught, which is the configuration worth paying attention to.

Who it is for

CPIx is built for founders, operators, and investors with exposure to consumer behaviour, anyone whose revenue, hiring, or portfolio depends on how financially resilient households actually are rather than how they say they feel. It is part of the Briefed Intelligence layer and is referenced in the daily briefing whenever the consumer picture is moving. You can see the live readings for the UK and US at briefedmedia.com/cpix.
