Stablecoins: how to separate volume, liquidity and reserve risk
Stablecoin activity matters to the market, but volume alone does not measure quality or safety.
Why they matter
Stablecoins connect fiat currency, exchanges and on-chain protocols. The BIS estimated the market at about USD 320 billion at the end of May 2026 and highlighted the dominance of dollar-linked coins. That is why changes in issuance, redemption and liquidity can matter to the wider ecosystem.
High volume, however, can reflect arbitrage, exchange internal transfers or short-term activity. It gains context when compared with circulating supply, issuance and redemptions.
Reserves and redemption
The structure of reserves, redemption rules, jurisdiction and transparency differ among issuers. Circle publishes reserve composition, flows and assurance reports for USDC; that information helps evaluate an issuer but is not a guarantee for the sector as a whole.
An operational checklist
Watch supply, issuance and redemption data, pair depth and deviations from the peg. Give more weight to consistent series than to isolated spikes.
