What it tracks
Filter. Constituents backed by bulk ferrous materials (iron-ore, hematite, magnetite, DRI pellets).
Weighting. Market-cap weighted.
A registered methodology slot for the bulk-ferrous complex — iron ore and its derivatives. No live retail token met eligibility at the base date, so no value is published yet.
Iron ore is the largest mined commodity by volume globally; the slot establishes prior art over the bulk-ferrous definition before tokenization pilots reach retail.
Comparable in spirit to: SGX TSI iron-ore reference price and Platts IODEX-linked benchmarks.
Constituents
0 / N ≥ 3Awaiting tokens meeting eligibility (Section 3 of the methodology: physical-metal backing, on-chain claim, issuer transparency, ≥ USD 1M market cap, public price feed, no double-counting). Currently 0 eligible constituents.
The rules are fixed and the slot is registered for prior art. No value is published and no constituents are listed until the threshold is met — we do not invent numbers from sparse data.
Publication threshold: N ≥ 3Computation
The index is recomputed daily at 00:00 UTC from CoinGecko closing-day market caps. Let MCi,t be the circulating market capitalisation of constituent i on day t, and MCi,0 its value on the base date (7 June 2026, base value 100).
Both cap-weighted and equal-weighted variants are rounded to 2 decimal places for display. New constituents are chained in at the next monthly review using a continuity multiplier so the historical series is not distorted. The full rules are fixed in the methodology document below.

Prior art
The TS-GMRI family (legacy mark “GMRI”) was first published on 7 June 2026 as the first publicly published market index dedicated to tokenized physical metals. Authorship: Andrey Kuznetsov, Hong Kong.

Disclaimers & notices
- Information product, not investment advice. TS-GMRI-FE is a proprietary index published by TrueSource Metals for informational purposes. Nothing here is a recommendation to buy, sell or hold any token or instrument.
- Liquidity caveats. Liquidity in the underlying tokens is uneven; cap-weighted values are sensitive to large moves in the dominant tokens (e.g. XAUT and PAXG). Small-N cuts can swing on single-name moves.
- Short history. The series is live since 7 June 2026 — only a handful of days of history exist. Volatility, drawdown and risk statistics are not yet statistically meaningful and are deliberately omitted.
- Unaudited. The index is unaudited at v1.0; an independent attestation is planned once 12 months of stable computation are available.
