We project that the consumer price index (CPI) will rise by 0.15% month-on-month in September, raising inflation from 3.8% to 4.2%, once again pushing past the deviation threshold of the CBI’s inflation target. The main reason for the increase is that the CPI fell by 0.3% month-on-month in September 2024, when free meals in primary schools were introduced. This one-off change drops out of the twelve-month measurement as of this September. In the months ahead we expect headline inflation to hold broadly steady at a level just above the CBI’s upper deviation limit. Statistics Iceland (SI) will publish the CPI for the month on 25 September.
Inflation forecast: Inflation to breach the upper deviation limit yet again
The outlook is for inflation to rise above the upper deviation limit of the Central Bank’s (CBI) inflation target again in September. The uptick is due primarily to base effects from one-off items that drop out of the measurements this month. Inflation will remain just above the deviation threshold for the rest of 2025.
Drop in airfares offsets end-of-sale effects
The summer spike in airfares generally reverses in August and September. Fares declined nearly 12% in August, and we expect them to fall by another 13.3% (-0.36% CPI effect) in September. Fuel prices are set to keep easing downwards, with our measurements suggesting a decline of 0.5% (-0.02%) this month.
End-of-sale effects on clothing and footwear prices were very modest in August, after shallow summer sales, which saw prices fell by an unusually moderate 4.9% in July. In August, though, clothing prices increased by only 0.7% MoM, taking us quite by surprise. We therefore project that end-of-sale effects will be strongest in September, with the clothing and footwear component jumping 3.7% (0.13% CPI effect). The price reduction from July will not reverse entirely, however, probably because of the appreciation of the ISK. We forecast that furniture and housewares prices will rise by 1.3% in September (0.06% CPI effect), driven by end-of-sale effects.
Dairy products push food prices higher
Food prices have been quite stable in the past two months, in a shift from the previous pattern. Most likely, the impact of wage increases earlier this year have already passed through to food prices for the most part, and the ISK appreciation is having an effect as well. We project that food prices will rise 0.3% (0.04% CPI effect), mainly because of price hikes on milk and dairy products. The agricultural pricing committee announced an increase in milk and dairy prices, effective at the start of September. Other foods and beverages will rise little, if at all, and the Icelandic Federation of Labour’s (ASÍ) grocery price index suggests that food prices will fall by 0.06% MoM.
Housing and other key items
The housing component as a whole is likely to rise by 0.4% (0.13%) MoM, owing largely to imputed rent, which increases by 0.45% (0.09%), according to our forecast. We also expect paid rent to rise by 0.9% (0.03%), in line with the pace set in recent months. Imputed rent has risen only modestly in the past two months. We expect that trend to continue in the near term, as the housing market is rather tame at the moment, although fluctuations in imputed rent are always a possibility.
Other items that will rise in price this month are recreation and culture, up 0.6% (0.07% CPI effect), and other goods and services, up 0.5% (0.02%). Hotel and restaurant prices will fall by 0.3% MoM (-0.02% CPI effect).
Inflation at or above the upper deviation threshold in the months to come
Headline inflation eased in August, in defiance of forecasts, and now measures 3.8%. This positive development in August changed the near-term outlook somewhat, and we now expect lower headline inflation in the months ahead. Even so, the outlook is for an uptick in September, with inflation at or above the 4% deviation threshold through the autumn. Our preliminary forecast for the months ahead is as follows:
- October: CPI to rise 0.3% (twelve-month inflation 4.2%) – Seasonal effects have tapered off. Most items pull in the same direction, increasing marginally. Headline inflation holds steady MoM.
- November: CPI to rise 0.2% (twelve-month inflation 4.3%) – Airfares fall, offsetting rises in other key items. Inflation ticks upwards slightly.
- December: CPI to rise 0.4% (twelve-month inflation 4.3%) – Airfares spike during the holidays. Other items increase marginally. Headline inflation holds steady MoM.
Twelve-month inflation will therefore hover around 4.2-4.3% in the next several months, according to our forecast, remaining just above the CBI’s 4% upper threshold. This is a more favourable outcome than we anticipated in August, but a far higher end-2025 inflation rate than was expected earlier this year. Headline inflation is clinging stubbornly to the upper deviation threshold and has measured 4% or more for virtually all of this year. ÍSB Research will publish a long-term inflation forecast together with its macroeconomic forecast later this month.
