What it tracks
Filter. All eligible constituents, cap-weighted with a single-issuer weight cap of 20%.
Weighting. Cap-weighted, single-issuer cap 20%.
A concentration-managed variant of the flagship. If any single issuer's combined cap-weight exceeds 20%, that issuer is scaled to the cap and the excess is redistributed pro-rata across uncapped tokens until stable.
Single-issuer concentration is the main structural risk in tokenized gold. Capping each issuer at 20% prevents any one balance sheet (e.g. Tether or Paxos) from dominating the gauge, giving a more diversified read on the category.
Comparable in spirit to: MSCI Issuer-Capped Indices and S&P Capped indices for single-name concentration management.
Constituents
18 constituentsAs of 2026-06-16 — updated daily at 00:00 UTC. Displayed weights are post-cap (single-issuer cap 20%, excess redistributed pro-rata). Unverified issuers are treated as standalone buckets.

Computation
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).
where ŵi are cap-weights after the iterative 20% single-issuer cap.
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.

Disclaimers & notices
- Information product, not investment advice. TS-GMRI-CAP20 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.
- Trademark notice. TS-GMRI™, GMRI™, and Global Metals RWA Index™ are trademarks of TrueSource Metals. Methodology © 2026 TrueSource Metals.
