Malaysia's producer price index (PPI) slid 3.4% year on year in April, faster than the 1.9% drop in the preceding month, the Department of Statistics Malaysia said Wednesday.

The PPI measures the average change in the prices charged by businesses in the manufacturing industry.

The decline was driven by the mining sector, which shrank 17.8% versus a 15% drop a month prior.

The manufacturing sector also slid 2.6% during the month, faster than the 1.8% decline a month prior. Similarly, the electricity & gas supply sector edged down 0.6% during the month, data showed.
