Romania’s annual inflation rate reached 10.9% in May 2026, according to data released by the National Institute of Statistics (INS). The increase marks a significant jump in the cost of living for Romanian citizens. Electricity prices were the primary driver of inflation, rising by over 55% in the past year. Rental costs and diesel fuel also contributed substantially, increasing by more than 40% and 36% respectively. These figures indicate a broad-based increase in prices across key sectors of the Romanian economy. The INS data highlights growing economic pressures on households and businesses alike. Further analysis is expected to determine the long-term impact of these inflationary trends.
