Conclusions
• The UK narrowly avoided falling into a technical recession as the
economy flatlined in Quarter 4 2022
• The labour market remains tight but there are some signs of a
cooling in labour demand
• External forecasts point to a challenging year ahead

There has been a decline in UK terms-of-trade
Ratio of export prices to import prices (PX/PM)
• Rate of exchange between internationally
traded goods and services produced by one
country relative to another country
• How many imports an economy can purchase
in its currency per unit of its exports
Movements in the terms-of-trade
• International cost of factors of production
• Exchange rate movements
• Rates of inflation between countries
• Productivity between countries

@ONSfocus #ONSEconForum slido #28660

Higher fuel prices has driven goods import inflation
The UK is a net energy importer
• Fuel price changes explain over 3/5 of the
increase in goods imports prices over the last
year
• Energy prices tend to be a key driver of
producer price inflation – direct and indirect
effects
Higher import prices
• Food and live animals – e.g. dairy and eggs
• Crude materials
• Fuels – e.g. gas and electricity
• Animal and vegetable oils & fats
• Chemicals – e.g. fertiliser

The largest negative UK terms-of-trade effect
since the mid-1970s
A change in the terms-of-trade has an impact on
the purchasing power of a country
• Real GDP: The volume of goods and services
produced by a country
• Real GDI: The purchasing power of a
country’s GDP over goods and services in
global markets
Real GDI falls relative to real GDP: (PX/PM)↓
• The purchasing power of domestic output is
diminished – a negative impact on welfare
• The same volume of exports can now be used
to purchase a lower volume of imports

unavoidable hit to UK real national income
• Production
• Welfare
The size and persistence of this terms-of-trade effect
• How these export and import prices evolve
• The reliance of net energy imports – (1) import substitution and (2) energy

• Obtaining Alternative Data Sources (ADS),
including scanner and web-scraped data
• Researching and integrating new methodologies
to process the data
• Developing statistical systems
• Embedding new processes
Allows us to improve the accuracy, efficacy and
representativity of consumer price inflation statistics
Primarily, new data will help us to inform the narrative
around what is driving inflation for our users.
@ONSfocus #ONSEconForum slido #28660

Rail fares data in CPIH, CPI, and RPI
• Transaction-level rail fares data will be incorporated in the CPIH, the CPI
and the RPI from February 2023, first published on 22 March 2023
• Historic impact analysis shows that the transformation of rail fares indices
would not have affected CPIH, CPI or RPI at headline level
• Small impacts (up to 0.1 percentage points) at Transport division level
• The key benefit of new data sources is the greater depth of
understanding on what is driving consumer prices trends
@ONSfocus #ONSEconForum slido #28660

Rail fares: Improved granularity of indices
• Data provided by the Rail Delivery Group, sourced from LENNON ticket
revenue system
• Publishing six new indices based on ticket types:
• Further stratification by individual regions in GB is calculated but not
published
• GB peak
• GB off-peak
• GB super off-peak
• GB advance
• GB short season
• Northern Ireland
@ONSfocus #ONSEconForum slido #28660

Quality assurance and testing
• Conducted an extensive readiness assessment
• Successfully mimicked live production using real data
• Thorough testing complete, providing a high level of confidence in the
data, system behaviour and their reliability
• Reviewed contingency plans and mitigating actions to ensure business
readiness for potential risks to monthly production round
@ONSfocus #ONSEconForum slido #28660

Update on second-hand cars
• Data and methods are more complex than rail fares (such as filtering and
imputation procedures)
• Quality assurance highlighted challenges in the methods that may affect
reliability of statistical production process
• We will be incorporating only rail fares into headline consumer price
statistics at this time
• Plans and timelines for second-hand cars will be updated in Spring 2023
@ONSfocus #ONSEconForum slido #28660

Final impact of transformed rail fares indices on
12-month rate for CPIH transport division
• Overall impact negligible on
headline consumer price
statistics
• Rail fares has contributed to less
than 7% of transport division of
CPIH since 2019
• Implemented improved outlier
detection and removal
methods, as detailed in
our Outlier detection for rail fares
and second-hand cars dynamic
price data methodology

What's next for prices transformation
• February 2023: we will incorporate the rail fares data into headline
consumer price statistics
• 22 March 2023: we will first publish our CPIH, CPI and RPI which
incorporates our rail fares data
• Spring 2023: we will publish our updated timelines as part of our
Transformation of UK consumer price statistics series

Transforming the ONS’s household financial
statistics consultation
We are seeking views on our ambitious plans for the transformation of our household financial
statistics.
These statistics cover the income, expenditure and wealth of UK Households and are a vital source
of information for understanding people’s finances including the effects from the rising cost of living.
This consultation sets out our plans for the next two and half years, laying out necessary
transformation steps, consistent with that longer term aim and building on our existing research in
this space.
We ask you to consider our proposals for the transformation of household financial statistics and to
provide your responses to this consultation by Thursday 23 February 2023.
