Producer prices on the domestic market grew by an annual 55.4% in October after jumping 78.1% in September. Last month's increase was mostly due to a 94.1% rise in the prices of electricity, gas, steam, and air conditioning supply.
At the same time, producer prices on the non-domestic market climbed by 19.6% on the year in October.
Compared to September, the PPI declined by 6.2% in October, mostly due to a 15.3% drop in prices in the electricity, gas, steam, and air conditioning supply category, the Sofia-based institute said.
