Platts proposes to launch Platts Construction Materials Index Dec. 1, 2026

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

The index would represent a global price based on a weighted basket of key construction materials and would provide a transparent indicator of changes in construction material costs.

This would be a daily weighted average index, published in $/mt, of the following component 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	45.10%
Ferrous scrap	Platts TSI HMS 1/2 80:20 CFRTurkey	TS01011	USD/mt		Daily	17.70%
Steel rebar	Steel Rebar FOBTurkey	STCBM00	USD/mt		Daily	19.60%
Cement	Platts CEMDEX FOBTurkey	ACEMF00	USD/mt		Weekly	17.60%

The index would 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 size of each commodity within the global construction sector by market capitalization, considering both prices and global demand/consumption.

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 would 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 index would be available on S&P Energy Core.

Details of Platts Global Commodity Indices methodology are available in the online specification guide, here: commodity-indices-specifications.pdf .
