The consumer price index (CPI) fell by 0.1% in January 2018 compared with the previous month, reaching 100.7 points (December 2015=100). Inflation was 0.7% compared with the same month of the previous year. These are the results of the Federal Statistical Office (FSO). The decrease of 0.1% compared with the previous month is due in particular to the decrease in prices for outpatient hospital medical services. Prices for air transport also declined, along with prices for clothing and footwear, in particular because of sales. In contrast, prices for overnight stays in hotels, heating oil and electricity increased.
