Indonesia's retail sales are projected to remain stable in April, albeit declining from the month prior, according to Bank Indonesia's Retail Sales Survey released on Tuesday.

The Real Sales Index (RSI) for April is estimated at 231, supported by continued annual growth in spare parts and accessories, other household equipment, and clothing sales.

Monthly, retail sales are forecast to decline 10% in April, following the Ramadan and Eid al-Fitr festive period, as consumer demand normalizes after the holidays, the central bank said.

Bank Indonesia warned that inflationary pressures are expected to increase over the next three and six months, due to rising raw material prices.
