Poland's PPI still in negative territory

Poland's PPI in May seems to be increased from April, but likely to be in negative territory. 

According to Societe genrale's estimation, "producers' price index to have jumped to -2.1% yoy in May from -2.6% in April. In monthly terms it is likely that PPI had increased by 0.3%, mainly due to higher manufacturing costs. Downward pressure on manufacturing costs is still strong and the PPI should remain below zero until end-2015."
