In August, inflation, the rate of price increase on an annual basis, was 9.0 percent, according to the consumer price index, i.e. the change from the same month last year.
It was the highest listing in 30 years.
This means that September's figures are a new record.
- Higher electricity prices and higher prices for food and non-alcoholic beverages affected inflation in September, says Caroline Neander, price statistician at Statistics Norway in a press release.
Among the food products, it was bread and other grain products that increased the most in price.
The price of coffee also had a big impact.
Rising interest costs also affected the inflation rate, according to Statistics Norway.
Electricity prices were roughly 54 percent higher in September this year than a year ago, while fuel prices fell in September.
The assessors had on average expected inflation of 9.3 percent, according to Bloomberg's compilation.
- There is great uncertainty around the whole thing, because what drives and causes it to a large extent are the high energy prices and they in turn depend on the war and Putin.
And there you have an element of uncertainty called enough, says Alexander Norén in SVT's Morgonstudion.
