The Consumer Price Index (CPI) did not change during the month of May compared to April, although the annual variation stood at -0.9%, down by two tenths compared to the previous month and the highest negative rate since May 2016. Housing was one of the few groups that saw its prices rise, up very slightly (by 0.078%).
The explanation for the negative data is largely due to the lower prices of fuels and the effects of the pandemic.
