USDP Peg Stability
As a Fiat-Backed stablecoin, USDP 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 USDP Maintains Its Peg
Paxos holds USDP reserves exclusively in cash and US Treasury bills in segregated trust accounts at US-regulated institutions. Paxos is legally required to hold reserves separately from operational funds under NY trust law. Monthly attestations are published by Withum. Users can mint and redeem USDP directly with Paxos through the Paxos API (institutional) or via exchanges. Paxos can freeze USDP on-chain in compliance with NYDFS directives and law enforcement requests. The token follows the ERC-20 standard on Ethereum with SPL on Solana.
Common De-peg Causes
During extreme market volatility, selling pressure on USDP 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 Paxos Trust Company.
Negative news about Paxos Trust Company, questions about reserve adequacy, or regulatory actions can cause holders to sell, pushing USDP 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 USDP, as holders flee to fiat. These events typically resolve as USDP's peg mechanism operates.
Monitoring the Peg
Track USDP 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.
