About this Publication

The Singapore Manufactured Products Price Index (SMPPI) monitors price changes of locally manufactured commodities. The weights of the index are derived from the distribution of local production by commodity in 2022. Ex-factory prices are obtained from principal manufacturers of the items concerned.

The Domestic Supply Price Index (DSPI) is designed to measure the changes in the price level of either commodities manufactured locally or imported, which are retained for use in the domestic economy by the government, business or household sectors. For imported products, the prices refer to those paid by importers in bringing the commodities into Singapore, commonly referred to as CIF prices. In the case of Singapore manufactured products, the quotations used are ex-factory prices. The weight for each commodity item is proportional to the value of its total supply or availability in the domestic market in 2022.

The 2023-based series is compiled using the 'modified Laspeyres' formula where the weight reference period of 2022 preceded the price reference period of 2023.
