US-Regulated Stablecoin Index

$79.53BMeasured supply▼ 0.8% / 30d

Dollar stablecoins whose issuers hold top-tier US regulatory standing — an NYDFS limited-purpose trust, a federal OCC national trust, or a NYDFS BitLicense with state money-transmitter licences — with a PCAOB-registered auditor and a current attestation. Scored on the same four-dimension rubric as the full stablecoin market.

The index level

Index level — quality, not size

The level is not a capital total — dollar amounts and their movement live in the strip above. It is the supply-weighted quality score of every constituent, on the 0–100 rating scale, recomputed daily. It rises when constituents score better or supply shifts toward stronger issuers, and falls when either reverses.

Insight

PYUSD (68/100) sits within 4 pts of the institutional-grade bar — $2.80B would cross on a score upgrade.

Constituents

The members

Every member’s issuing entity and US regulatory basis sit in the table beside its measured supply, index weight, and score. Membership is set by that standing; the score reports how each issuer measures against the rubric once inside it.

Where the supply lives

Where it lives

Each member’s supply is read from every chain it mints on — native issuance only, so bridged copies never double-count the Ethereum-locked supply they re-issue. The composition below is the onchain footprint behind the headline number.

The inclusion rule

The inclusion rule

A constituent is included if, and only if, all three hold:

01 · TOP-TIER US REGULATORY STANDING

Inclusion requires top-tier US regulatory standing — a trust charter, or a BitLicense with state money-transmitter licences.

A stablecoin enters this index when its issuer holds a New York limited-purpose trust charter, a federal OCC national trust charter, or a NYDFS BitLicense together with state money-transmitter licences. PYUSD, USDP, RLUSD, GUSD and USDGO clear it on a trust charter; USDC clears it on Circle's BitLicense and state money-transmitter licences. The largest stablecoin by supply, USDT, does not, and is measured in the broader Stablecoin Quality Index instead.

02 · PCAOB AUDITOR

A PCAOB-registered auditor must attest the reserves.

Regulatory standing admits the issuer; a PCAOB-registered auditor attesting the reserve is the second gate. An issuer with the right standing but no PCAOB attestation is excluded until the attestation exists — the requirement is mechanical, not discretionary.

03 · RECENT ATTESTATION

The most recent attestation must be current, not historical.

The rubric

The rubric

Each member earns up to 25 points on each dimension, independent of issuer self-reporting. The band a member lands in follows directly from the total.

The four dimensions

01Reserve qualityWeight 25%

Composition and chain-verifiability of what backs supply. Cash + T-bills with onchain-readable composition scores highest; synthetic crypto-collateral scores lower.

02Redemption depthWeight 25%

Genuine ability to exit — issuer direct redemption and DEX onchain depth at 1% slippage. A joint-path bonus applies when both paths exist.

03Holder concentrationWeight 25%

Top-10 holder share post-exclusion of known exchange and protocol addresses. Lower concentration scores higher.

04TransparencyWeight 25%

Attestation freshness, disclosure consistency over trailing 180 days, and regulatory standing. Voluntary-attestation cap applies at 19.

Constituents, dimension by dimension
How it’s computed

Methodology

The four dimensions, the equal 25-point weights, the institutional-grade band at 70, and the exclusion rules are the OCB stablecoin rubric. The index aggregates each member’s supply-weighted score into a daily 0–100 level. Any analyst applying the same rubric to the same onchain evidence should arrive at the same number; methodology changes are version-bumped and logged publicly.

Why trust it

Regulated coverage

The regulated set, four dimensions, one framework.

  • 6 stablecoins in the index clear the top-tier US regulatory bar — USDC, PYUSD, RLUSD, USDGO, GUSD, and USDP — each scored under the same published rubric as the full market.
  • Each instrument is evaluated independently on Reserve Quality, Redemption Depth, Holder Concentration, and Transparency — four equal-weight 25-point dimensions.

Standing is not a score

The regulatory bar decides membership; the rubric decides the number.

6 constituents · 6 of 6 scored · supply-weighted · methodology v1.0-us-regulated-stablecoin · Oct 16, 2026

Inclusion is a live fact, re-checked as attestations refresh and as issuers convert charters. Paxos moved from NYDFS to the OCC in December 2025; PYUSD and USDP moved with it. The index tracks the standing and attestation each issuer holds today, not the one it launched under.

A coin sits outside this cut for one of three reasons: the issuer holds no top-tier US regulatory standing (USDT and USDC.e-style offshore or bridged supply); the reserve carries no current PCAOB attestation; or the instrument is not a stablecoin of the type this index tracks.

Top-tier regulatory standing admits a stablecoin to the index. It does not set the stablecoin's health score — that comes from the same onchain evidence applied to every instrument.
  • A member can hold the highest standing and still score Monitored on reserve composition, redemption depth, or holder concentration. The two are measured separately, and both are shown.
  • Daily methodology

    Published, versioned, and change-controlled.

    • Scores compute daily. Every methodology change increments the version and is logged in the public changelog.
    • Historical scores are never silently rewritten. A reader citing a score on any past date will always find the same number.
