ICAEW chart of the week: Inflation

My chart for ICAEW this week illustrates how core inflation has only dropped from 6.3% in December 2022 to 5.1% in December 2023, even as the headline rate has come down from 10.5% to 4.0%.

Two step charts under the title 'Inflation'.

Step chart 1: 2022

Core inflation +6.3% (corresponding to 5.0% in height)
+ Food prices +16.8% (height 1.8%)
+ Alcohol & tobacco +3.7% (height 0.2%)
+ Energy prices +52.8% (height 3.5%)

= CPI all items +10.5% (height 10.5%)

Step chart 2: 2023

On 17 January 2023, the Office for National Statistics (ONS) published its latest consumer price inflation (CPI) statistics for the 12 months to December 2023, reporting that headline inflation has fallen to an annual rate of 4.0% compared with 10.5% a year earlier – a more than halving of the annual rate of price growth.

This contrasts with CPI excluding energy, food, alcohol and tobacco (typically described as core inflation), which was 6.3% and 5.1% in the 12 months to December 2022 and 2023 respectively.

The left-hand side of my chart this week illustrates how core inflation in the 12 months to December 2022 of 6.3% contributed just under 5.0% to the weighted average total inflation rate of 10.5%, with food prices up 16.8%, alcohol and tobacco up 3.7%, and energy prices up 52.8% contributing a further 1.8%, 0.2% and 3.5% respectively.

The right-hand side shows the 12 months to December 2023, where core inflation of 5.1%, food price inflation of 8.0%, alcohol and tobacco inflation of 12.9%, and a fall in energy prices of 17.3% contributed approximately 4.0%, 0.9%, 0.5% and -1.4% respectively to the weighted average total rate of consumer price inflation of 4.0%

The relative weightings may explain why many people feel that inflation is still running faster than the headline rate. Food prices, up 8.0% in the past 12 months, have increased twice as fast as CPI of 4.0%, while alcohol (up 9.6%) and tobacco (up 16.0%) have gone up by even more. These may have been offset by energy prices coming down by 17.3% over the past 12 months, but this may not be perceived as that beneficial given how energy is still significantly more expensive than it was before the cost-of-living crisis started.

For policymakers, the bigger concern will be the stickiness in core inflation, which remains stubbornly higher than the Bank of England’s target for overall CPI of 2.0%. While the expectation is that both core and headline rates will come down further during the course of 2024, the Bank is likely to remain cautious about declaring victory in the fight against inflation despite worries about the effects of high interest rates on the struggling economy.

ICAEW chart of the week: Consumer Price Inflation

My chart this week looks at how the benchmark percentage used to determine the rise in the state pension and many welfare benefits from next April reached 10.1% in September 2022.

Line chart showing the CPI index over 4 years, together with the annual percentage change to each September.

Sep 2018: 106.6
(intermediate quarters 107.1, 107.0, 107.9)
Sep 2019: 108.5, +1.7% over prior year
(108.5, 108.6, 108.6)
Sep 2020: 109.1, +0.5%
(109.2, 109.4, 111.3)
Sep 2021: 112.4, +3.1%
(115.1, 117.1, 121.8)
Sep 2022: 123.8, +10.1%

The ICAEW chart of the week is on consumer price inflation, illustrating how the CPI index rose from 106.1 in September 2018 to 108.5 in September 2019, 109.1 in September 2020, 112.4 in September 2021 and 123.8 in September 2022. According to the Office for National Statistics (ONS), this meant that annual consumer price inflation was 1.7%, 0.5%, 3.1% and 10.1% for each of the four years to September 2022.

The percentage increase in the consumer price inflation index to each September is an important number as it is used to uprate most welfare benefits from the following April. In addition, under the triple-lock formula that has just been recommitted to by the government, it will be used to uprate the state pension in place of the statutory requirement for a rise in line with average earnings, which in September 2022 was 5.5%.

There has been speculation that the Chancellor of the Exchequer might try to restrict the uprating of welfare benefits (other than the state pension) to below inflation in order to meet his fiscal objectives. However, there is significant political pressure not to do so during a cost-of-living crisis that means many households are already struggling to pay their bills, even before the large rise in energy prices this month.

In theory, the sharp upward slope in the index over the last year provides some hope for both consumers and the Bank of England, as price increases from a year earlier fall out of the index, at least from November onwards given the energy price guarantee that means domestic energy prices should be flat for the following six months. With petrol and diesel prices appearing to moderate, and the ‘medicine’ of higher interest rates starting to take effect, the hope is that prices will rise less rapidly than they have this year, and so cause the annual rate of inflation to fall in the first half of next year.

Having said that, if recent events have taught us anything it is that our ability to predict the future is far from perfect.

ICAEW chart of the week: Consumer Prices Index

My chart this week looks at how price rises have accelerated over the last few months, with consumer price inflation reaching 4.2% in October, the highest it has been for a decade.

Line chart showing how the Consumer Prices Index has increased from 106.7 in Oct 2018 to 107/6 in Apr 2019 to 108.3 in Oct 2019 (a +1.5% increase over a year earlier) to 108.5 in Apr 2020 to 109.1 in Oct 2020 (up 0.7% over the year) to 110.1 in Apr 2021 to 113.6 in Oct 2021 (a 4.2% annual increase).

The Office for National Statistics published its latest estimates for inflation on Wednesday 17 November, reporting a 12-month increase in the Consumer Prices Index (CPI) of 4.2% and a 12-month increase in the Consumer Prices Index including owner occupiers’ house costs (CPIH) of 3.8%, both of which are the highest they have been since November 2011 when CPI was 4.8% and CPIH was 4.1%.

CPI and CPIH are calculated using a basket of goods and services to assess the level of inflation experienced by consumers, with the current index set to 100 in July 2015.

The ICAEW chart of the week shows how CPI fell before increasing from 106.7 in October 2018 to 107.6 in April 2019 and 108.3 in October 2019, an annual increase of 1.5% that was within the 1% to 3% Bank of England target range. This was followed by smaller increases to 108.3 in April 2020 and 109.1 in October 2020, a 0.7% annual increase in CPI driven in part by the pandemic. The index hovered around that level for several months until starting to increase more rapidly from March onwards as the economy started to re-open, reaching 110.1 in April 2021 and continuing to increase sharply to 113.6 in October 2021, an annual increase of 4.2%.

The Governor of the Bank of England is required to write to the Chancellor of the Bank of England whenever inflation is more than 1% above or below the 2% target and he did so on 23 September when inflation reached 3.2% and he will again now that it has reached 4.2%. Part of the explanation he has given and will give are ‘base effects’, where price discounting during 2020 at the height of the first and second waves of the pandemic suppressed some of the inflation that is being experienced now.

Further letters are likely over the next few months as even if prices don’t rise any further, given how the index bounced around the 109 level between September and March 2021. This means inflation should continue to stay substantially above 3% for the next four months or so unless prices were to fall again, which is unlikely given how global commodities and supply constraints continue to feed into rising domestic prices. A 12-month CPI-inflation rate of 5% appears more than likely at some point in the next few months.

The Bank of England’s Monetary Policy Committee (MPC) isn’t panicking at this stage given that the annualised rate of inflation over the last three years (comparing October 2021 with October 2018) is an almost on-target 2.1% and their expectation that inflation rate will come down once the flat inflationary period of a year ago starts to drop out of the comparison. However, they are sufficiently concerned about the steep slope in the CPI in the last few months to signal that interest rates may need to rise if prices continue to increase at the pace seen in recent months.

The MPC’s original plan was to hang tight through what they hoped would be a short inflationary spurt as the economy emerges from the pandemic. In the event it looks like they won’t be able to hold that line, with higher interest rates a distinct possibility in the coming months.

ICAEW chart of the week: UK inflation

This week’s chart takes a look at UK inflation following news that the annual rate of inflation more than doubled in April to 1.5%, more than twice the 0.7% reported for the previous month.

Chart: CPI increasing from less than 0.5% in Apr 2016 to over 3% in Oct 2017 before falling to close to zero in Oct 2020, zigzagging to 0.7% in Mar 2021 and then jumping to 1.5% in Apr 2021. 

Compared with five year annualised rate gradually increasing from 1.5% in 2016 to close to just under 2% now.

The headline rate of inflation doubled this week from 0.7% to 1.5%, giving rise to concerns about the economic recovery. Economists aren’t getting worried just yet, but are they right to be so sanguine? 

This scale of this jump partly reflects the timing of the first and current lockdowns, as inflation is typically measured by comparing prices with the same month a year previously, with significant changes both this year as the UK started to emerge from its third lockdown and a year ago as it was entering its first. Some commentators have pointed out that the temporary cut in VAT on restaurant food and leisure activities help prevent the jump from being even higher.

Our chart compares the annual rate of Consumer Price Index (CPI) inflation with a more stable measure, which is the annualised rate of CPI inflation over a five-year period. This is less susceptible to short-term swings in the economy, but as the chart shows, medium-term inflation has been gradually rising over the past five years even as headline rates on an annual basis fell over the last four years before the pandemic.

This perhaps explains some of the relaxed responses from economists about the sudden burst in inflation in the last month, given the annual rate of increase still remains below the medium-term trend, despite the current extraordinary economic circumstances.

Of course, that is not to say that inflation might not become a problem as the UK emerges further from lockdown. Many businesses have closed over the last year, particularly in the retail sector, while those that have survived will be looking to repair their balance sheets – a recipe for higher prices as constrained supply meets higher post-lockdown demand from consumers. Only time will tell whether this will feed into sustained higher levels of inflation or will jump be a temporary adjustment that falls out of the headline rate again in a year or so’s time.
