Bulgaria's industrial producer price index (PPI) rose by 13% on the year in May, after increasing by 9.8% in the previous month, the National Statistical Institute (NSI) said on Wednesday.
The annual increase in the PPI index was predominantly supported by a 31.1% rise in the mining sub-indicator, the NSI said in a statement.
On a monthly comparison basis, industrial producer prices in Bulgaria rose by 1.9% in May, after they edged up 0.3% in April.
The industrial PPI on the domestic market climbed up by an annual 8.9% and added 1.3% on a monthly comparison basis. The industrial PPI on the non-domestic market increased by 19.7% year-on-year and rose 2.7% month-on-month.
