UK inflation increased to 3.4% in December, driven mainly by higher tobacco and airfare prices. This uptick from the 3.2% recorded in November marks the first rise in the headline rate in five months, contrary to the expectations of most economists.
The Office for National Statistics (ONS) releases monthly data on inflation, which tracks changes in the prices of goods and services over time. The December surge in inflation was attributed to a rise in tobacco duty, leading to higher cigarette prices, and increased airfare costs during the holiday season. Additionally, some food prices, such as bread and cereals, saw an uptick. However, these increases were partially offset by a decline in rent prices and lower oil costs, impacting raw material prices for businesses.
Grant Fitzner, the chief economist at the ONS, highlighted that the inflation rise in December was influenced by higher tobacco prices due to recent excise duty hikes, along with increased airfares and food costs. The rise in factory goods prices remained steady, while the growth in raw material costs for businesses slowed, driven by lower crude oil prices.
Inflation serves as a measure of how prices have changed compared to the previous year. When inflation decreases, it does not indicate a halt in price increases but rather a slower rate of increase. If prices were to decrease, it would be termed deflation when inflation falls below 0%.
The Bank of England targets 2% inflation and had raised interest rates over nearly two years to curb inflation. Higher interest rates lead to increased borrowing costs, reducing consumer spending and demand, ultimately lowering prices and inflation. However, the elevated base rate resulted in higher mortgage payments for many homeowners, straining household finances. Despite reaching a peak of 5.25% in August 2023, the base rate has been subsequently cut six times to the current level of 3.75%.
Inflation began its ascent in 2021, peaking at 11.1% in October 2022, primarily driven by escalating energy and food costs. The demand for energy surged post-Covid, exacerbated by the Russian invasion of Ukraine, which also pushed up food prices due to increased expenses for fertilizers and animal feed. Although inflation hit a three-year low of 1.7% in September 2024, it started to rise again the following month in October 2024.
