On the month, industrial producer prices fell 0.6%.
The prices at which industrial products were sold on the home market in April 2015 were 3.2% lower than in April 2014, while the prices abroad decreased 3%.
The latest figures confirm a continuation of deflationary pressures over the past two years, Raiffeisenbank Austria analysts said, adding that they expected industrial producer prices to continue to fall year on year, mainly due to weak domestic demand and a lack of inflationary pressures on foreign markets.
