USD Coin (USDC) at a glance: 9.50/10 in July 2026
USD Coin (USDC) is a stablecoin issued by Circle, pegged to the US dollar via cash + us treasuries. On our six-criterion composite for stablecoins, it currently leads our composite ranking, ahead of USDS (Sky) and PayPal USD.
Stablecoin scoring weights collateral quality, transparency, and depeg history heavily — combined they represent 55% of the composite. For any stablecoin holding meaningful capital, these are the questions that determine tail risk.
Transparency and audit posture
Circle is a publicly-listed US company (NYSE: CRCL, IPO 2024) — quarterly 10-Q + annual 10-K SEC filings. Monthly reserve attestations by Deloitte. Reserves held at BNY Mellon and other regulated US banks. Highest-transparency stablecoin issuer.
Transparency is the single strongest predictor of stablecoin trust. Public quarterly audits by Big Four accounting firms (or better, full SEC filings from publicly-listed issuers) rank highest. Attestations are lower-tier but still meaningful. Opaque or infrequent disclosure is a persistent risk flag.
Regulatory posture
US FinCEN-registered MSB. NYDFS approved. EU MiCA-compliant via Ireland (issuing EURC and USDC compliantly in EU). Licensed in most US states. Fully compliant across all major jurisdictions.
Regulatory registration matters both for user access (can you legally hold this stablecoin in your jurisdiction?) and for issuer resilience (can the issuer survive a hostile regulatory action?). MiCA compliance is the current baseline for EU access; NYDFS oversight is the strongest US signal.
Collateral quality
Reserves entirely in cash and short-duration US Treasuries — highest-quality collateral available. No lending, no commercial paper, no exotic assets.
Collateral composition determines what happens if the issuer needs to redeem all stablecoins at once. Pure cash + short-duration US Treasuries is highest-quality — instantly liquid, minimal duration risk. Commercial paper, secured loans, or crypto-backed collateral carry additional risk that only matters until it does.
Peg stability history
March 2023: depegged to $0.87 briefly during Silicon Valley Bank crisis when $3.3B of reserves were temporarily exposed. Recovered fully within 3 days once federal deposit guarantee was extended. No other meaningful depeg events.
Depeg events are the most-visible stablecoin failure mode. A stablecoin that has held peg through multiple stress events (Terra collapse 2022, SVB crisis 2023) has meaningfully demonstrated its design vs one that has not been stress-tested.
Supply scale and adoption
Circulating supply of $73.37B — top-tier stablecoin by adoption. Widely accepted across CEXs and DeFi. Top-3 stablecoin by supply — used as base currency across virtually every CEX and DEX.
Larger supply usually correlates with better acceptance across trading venues and DeFi protocols. But it also concentrates issuer risk — a failure of a top-3 stablecoin would create systemic pressure across all of crypto.
Who USD Coin (USDC) is for — and who should look elsewhere
Best fit: US and EU users who need a fully-compliant stablecoin with the strongest regulatory posture and full public audit trail.
Look elsewhere if: USD Coin (USDC) suits nearly all mainstream stablecoins use cases within its coverage — only edge cases (specific chain requirements, ultra-large capital, or specialised product needs) are likely to push you elsewhere.
USD Coin (USDC) currently leads our stablecoin composite.
