"Unpredictability of geopolitics and energy markets" could stoke inflation fire above 3%
With the price of gas rising as much as 75% since February, Ofgem has increased the energy price cap in Q4 to £1,717 from £1,568. Previously, the deflationary impact of energy prices had tremendously helped to bring headline inflation down to the Bank of England’s (BoE) 2% target. But with that deflationary tailwind now beginning to subside, CPI peeked back up above the BoE’s 2% target in July.
The Bank of England (BoE) may have factored this into its forecasts, but the Bank still estimates CPI to peak at 2.7% in Q4 before returning back to its 2% target in early 2026. However, what the market doesn't seem to have accounted for is an element of uncertainty and worry, as any further uptick in gas prices from their current levels could have a detrimental effect on CPI, and force inflation to remain above the BoE’s 2% target for a longer period.
Energy has a direct impact on approximately 27% of the Consumer Price Index (CPI) basket through the “Housing and Household Services” and “Transport” categories. This makes it the biggest determinant of inflation, and that’s not including the spillover effects of higher energy prices through other categories such as food, apparel, and travel.
In October 2022, when inflation hit its peak of 11.1%, both energy-heavy categories contributed to 45% of the inflation basket. Since then, however, energy prices have subsided and have even been deflationary in certain months.
The good news is that the energy price cap tends to have a one-quarter lag behind gas prices. Thus, with gas prices cooling since hitting a recent peak earlier this month, consumers could see a lower energy price cap return in Q1 of next year. But on the other hand, with geopolitical tensions running high, this puts gas prices at a pivotal juncture, as any further increases could easily lead to higher inflation.
