TrueSource Metals™ index family

The TS-GMRI family — full taxonomy

The TS-GMRI family is one coherent taxonomy: a shared constituent universe, a shared base date 7 June 2026 = 100, and shared data-discipline rules. Members differ only in their filter (which constituents) and weighting (how they combine). Members with N ≥ 3 active constituents publish a live value; below the threshold they are registered as methodology slots — rules fixed, value withheld, no invented numbers. Each member has a dedicated page. The canonical rules live in the methodology v1.0.
