Platts to launch Global Construction Materials Index Dec. 1

Platts, part of S&P Global Energy, will launch the Platts Global Construction Materials Index, effective Dec. 1, 2026.

The index will represent the weighted value of a basket of key construction materials and will provide a transparent indicator of changes in construction material costs. The index will be calculated as a weighted average of its component assessments and would be expressed in US dollars per metric ton.

The Platts Construction Materials Index [ PCMIA00] will include the following Platts assessments:

Commodity	Assessment	Symbol	Currency/UoM	Conversion Factor	Assessment frequency	Weighting in Index
Hot-rolled coil	Platts TSI US HRC EXW Indiana	STHRI00	USD/short ton	1.102311	Daily	45.1%
Ferrous scrap	Platts TSI HMS 1/2 80:20 CFR Turkey	TS01011	USD/mt		Daily	17.7%
Steel rebar	Steel Rebar FOB Turkey	STCBM00	USD/mt		Daily	19.6%
Cement	Platts CEMDEX FOB Turkey	ACEMF00	USD/mt		Weekly	17.6%

The index will combine assessments representing key segments of the construction materials value chain, including finished steel products, steelmaking feedstocks, reinforcing steel and cement.

Weightings are designed to reflect the relative economic significance of each commodity within the global construction materials market. The methodology considers both prices and demand characteristics to provide broad representation across major construction material categories.

The following table details the sources of the demand figures used to calculate the weightings of each commodity:

Commodity	Weighting Basis	Source
Hot-Rolled Coil (HRC)	Global flat steel demand	World Steel Association
Ferrous Steel Scrap	Global steel scrap consumption	Bureau of International Recycling (BIR) and World Steel Association
Steel Reinforcing Bar (Rebar)	Global long steel demand (used as a proxy for rebar consumption)	World Steel Association
Cement	Global cement demand	United States Geological Survey (USGS)

Demand data will be reviewed periodically and may be updated as part of the annual weighting review process. Where commodity-specific consumption data is not available, representative industry proxies may be used.

The Construction Materials Index will be calculated daily and published in US dollars per metric ton.

The index will be available through S&P Global Energy Core.
