Hello mates! It’s no secret that FT Alphaville has been pondering rather a lot about UK inflation stats for fairly a while. So what’s the hurt in doing just a little extra? In any case, you’re in all probability not doing any work at this time.

Earlier this month, we dwelled upon the smallcagedmammalness of sure objects that the Workplace for Nationwide Statistics screens. Let’s attempt to outline that phrase:

smallcagedmammalness noun
: the propensity of an merchandise inside the Workplace for Nationwide Statistics inflation basket to generate strikingly disparate value observations, indicating ONS brokers are usually not observing comparable objects.

On the threat of partaking in pointless frog dissection/weblog exegesis, this was the partial thrust of our authentic small caged mammal put up: that the bizarre unfold of recorded costs indicated that totally different small caged mammals have been being noticed — throwing the worth of the measurement into query, and highlighting points with the ONS’s methodology.

As we method that article’s first birthday, let’s increase the evaluation barely. The ONS’s detailed inflation tables ostensibly anonymise the retailers the place its brokers made value observations, assigning every a singular ID inside its area. One value is recorded per store per thirty days, however not each store seems each month.

We used this in our Taylor Swift piece on Wednesday to reverse engineer whether or not there had been value gouging at resorts close to her gigs.

And, with the facility of know-how, we will do this once more however greater. So we mixed each small caged mammal value studying since December 2019 right into a single information set, divvied them up by store and created a value time sequence for every store’s month-to-month noticed value.

Earlier than we drop a lot of charts, let’s set up some free vibes. To start with, let’s take a look at the typical value of a small caged mammal in line with the ONS.

The ONS already publishes value sequence for some particular person objects, however small caged mammal isn’t amongst them so (so far as we will inform) it’s a easy matter of merging a bunch of spreadshee—

—ach.

OK right here it’s:

If one already had considerations in regards to the small caged mammal scenario, this chart would in all probability do little to allay them. Nevertheless it’s not utterly wild: plausibly an enormous participant reminiscent of Pets At Residence might have shifted the entire index increased via most of 2023 with a short lived value improve.

Now, about these particular person retailers. We assigned every of them a singular ID, combining their area identify and store code (eg ‘East Anglia-011’), and obtained charting.

In a bizarre, kinda good world, the noticed costs at particular person retailers may kinda sorta match the chart above: principally regular, possibly rising just a little in 2023.

Extra realistically, we’d anticipate is:

— a whole lot of flat traces: retailers that haven’t modified their costs.
— some traces with rare step adjustments and plateaus: for outlets that did change costs, and people maybe briefly elevating them. For smaller unbiased retailers, that is in all probability a matter of Maureen and Pete checking their power invoice and realising that after a decade it’s time to place hamsters up from £10 to £12.
— some traces with minor wiggling or small, regular will increase: corporations with extra pricing energy and sight of the market is likely to be anticipated to make extra frequent, small changes to costs.

What we shouldn’t hope to see is:

— wild, whipsaw month-to-month adjustments: which might point out both a weird pricing system, or (extra seemingly) issues within the information gathering course of

What may go away us scratching our chins is:

— costs present process one-off, huge will increase: if a value triples then stays regular, are we an error or a significant pricing correction? Are Pete and Maureen value gouging? Are hamsters simply constructed totally different now?

So, with out additional ado, right here’s virtually 200 line charts. See you on the backside:

Welcome again. As you’ve hopefully noticed, there may be a whole lot of weirdness in these figures.

First up: good — within the majority of instances we’re flattish traces with small changes (normally upwards), as anticipated.

However hoo boy are there additionally another varieties. Listed here are a few of our favourites:

Let’s… attempt to narrativise these. Left to proper, from high:

— East Anglia-017: [Early 2022] “Doreen, did we promote the final mouse?” “Sure, Keith.” “OK by no means purchase any extra, this can be a premium guinea pig emporium now.”
— East Anglia-071: [Late 2020] “Hello, you understand how we’re on the lookout for small caged mammals?” “Yeah, why?” “Are you able to attempt a bit smaller?”
— East Midlands-012: [Some time pre-2020] After an extended and satisfying profession at Jane Road, Malcolm opened a pet store in Wellingborough.
— London-035: [2020–2024] Davide had been on the ONS small caged mammal beat for some time now, and nonetheless wasn’t actually certain what he was on the lookout for.
— North West-014: [October 2023] “Merseyside Mice is proud to announce: We as soon as once more have mice.”
— Scotland-016: [2020–2024] Drawing a six-sided cube from her coat pocket, Anita ready to find out what sort of mammal she’d take a look at this month.
— Scotland-029: [Late 2019] “We gotta swap issues up. The sub-£45 mammal market — that’s the place the cash is.”
— Scotland-050: [2021] “This isn’t how gross sales work, dad.”
— Wales-012: [2022 onwards] “Rhys, is it that chap from the ONS again?” “Sure mumma.” “All proper, elevate the worth once more.”
— West Midlands-089: [Always] “Why do folks say Solihull is bougie?”
