UK inflation increased to 3.4% in December, primarily driven by higher prices for tobacco and airfares. This uptick from the 3.2% recorded in November represents the first rise in the headline rate in five months, contrary to expectations of most economists.
Inflation reflects changes in the prices of goods and services over time, with monthly data released by the Office for National Statistics (ONS). The December surge was attributed to a spike in tobacco duty leading to higher cigarette prices, as well as elevated airfare costs during the holiday season.
The ONS also highlighted increased expenses for certain food items like bread and cereals, offset by a decline in rental prices and lower oil costs affecting raw material prices for businesses. Grant Fitzner, the ONS chief economist, explained that the uptick in inflation was influenced by higher tobacco and airfare prices, alongside rising food costs. These were balanced by reduced rents and prices for recreational items.
Inflation indicates how much more expensive something has become compared to the previous year. The ONS calculates inflation based on a basket of goods and services regularly updated to reflect consumer spending patterns. The main inflation figure reported is an average, with individual prices of goods potentially varying higher or lower than this figure.
The Bank of England targets a 2% inflation rate and has adjusted interest rates over nearly two years to manage inflation towards this goal. Higher interest rates increase borrowing costs, limiting spending and reducing demand, ultimately curbing inflation. However, the impact of higher rates increased mortgage payments for many households.
Inflation had surged to 11.1% in October 2022, driven by escalating energy and food prices following increased demand post-Covid and exacerbated by the Ukrainian conflict. After reaching a three-year low of 1.7% in September 2024, inflation started to rise again in October of the same year.
