TUSD Peg Stability
As a Fiat-Backed stablecoin, TUSD is designed to maintain a $1.00 peg at all times. Peg stability is the most critical metric for any stablecoin — a persistent de-peg can trigger a loss of confidence, mass redemptions, and cascading liquidations in DeFi protocols that depend on the token.
How TUSD Maintains Its Peg
TUSD is minted by depositing USD with authorized custodians, historically Prime Trust and more recently Asian-based banking partners. Minting and redemption are handled through the TrueCurrency platform. Chainlink Proof of Reserve oracles are supposed to verify on-chain that total TUSD supply does not exceed held reserves. The protocol experienced issues in 2023 when Prime Trust was placed into receivership, causing temporary minting halts and de-peg events. Reserve attestations are now conducted by independent accounting firms on a regular basis.
Common De-peg Causes
During extreme market volatility, selling pressure on TUSD can exceed available buy-side liquidity on exchanges. This causes temporary downward deviations until arbitrageurs step in to buy discounted tokens and redeem for $1 from TrustToken / Archblock.
Negative news about TrustToken / Archblock, questions about reserve adequacy, or regulatory actions can cause holders to sell, pushing TUSD below $1.00 on secondary markets even if reserves are fully intact.
Failures of other stablecoins (e.g., UST/Luna collapse) or crypto lenders can cause panic selling across all stablecoins, including TUSD, as holders flee to fiat. These events typically resolve as TUSD's peg mechanism operates.
Monitoring the Peg
Track TUSD peg deviations in real-time using the BTC.PH Depeg Monitor. Set alerts for deviations below $0.995 or above $1.005 to react quickly to potential instability.
