Analysis
Stablecoin issuance hit a record ~$320B in March 2026 even as the broader crypto market fell more than 20% from its cycle high, underlining stablecoins' role as a liquidity rail rather than a speculative asset. Tether and Circle continue to hold a combined >80% share, with the GENIUS Act now mandating 1:1 cash/Treasury backing and monthly attestation — a regulatory regime that explicitly favours the larger, more transparent issuers and is widely expected to consolidate share further over 2026.

Caveats
- The 2026-Q1 endpoint values (USDT $184B / USDC $78B / others $58B = ~$320B total) are source-verified against the brief's March 2026 record.
- Earlier quarterly values are illustrative reconstructions following the DefiLlama public series trajectory (depeg dip / recovery / new highs) — directional, not point-precise. Per-quarter values to be re-verified against DefiLlama before publication.
- Nothing here is investment advice; stablecoin holdings carry issuer, regulatory, and de-peg risk.
