NIESR reacts to the latest ONS CPI inflation statistics released this week

23 May 2019 12:13 PM

According to figures released yesterday by the ONS, consumer price index inflation increased by 0.2 percentage points to 2.1 per cent in the year to April 2019. However, our new analysis of 131,181 locally-collected goods and services prices included in the index this month suggests a reduction in inflationary pressure.

Main points

Dr Jason Lennard, Senior Economist, yesterday said: 

“Headline CPI inflation increased by 0.2 percentage points to 2.1 per cent in the year to April 2019. Our analysis of more than 130,000 goods and services included in the basket, however, suggests a decline in inflationary pressure. Our measure of underlying inflation, which excludes extreme price movements, decreased by 0.2 percentage points. Price decreases outnumbered price increases by a margin not seen at this time of year since at least the 1990s. Underlying inflation fell in every region of the United Kingdom. This suggests that a few volatile items, such as air fares and energy, contributed to the increase this month. On this basis, we expect CPI inflation to settle just below the Bank of England’s target of 2 per cent in the coming year.”

This analysis builds on the work presented in the National Institute Economic Review, which constructs a measure of trimmed mean inflation based on the goods and services prices that underlie the consumer price index.

Our next analysis of consumer prices will be published on 19 June.

 

Figure 1. Inflation: CPI and trimmed mean

Note: Our measure of trimmed mean inflation excludes 5 per cent of the highest and lowest price changes. The level of trimmed mean inflation is typically lower than CPI inflation due to differences in how the largest price changes are treated and to how the prices are weighted.
