How to check a stablecoin peg deviation

Purpose

Quantify premium or discount to the peg before you size transfers, LP deposits, or treasury moves that assume $1.

When to use it

• A stablecoin prints away from $1 on your venue
• Before depositing into a pool that assumes parity
• When bridging value represented in stables
• During market stress headlines

How to use it

1. Enter the market price. Use the venue price you actually trade.
2. Read deviation. See premium/discount versus the $1 target.
3. Compare venues. Dislocations across markets can signal stress or opportunity — and risk.
4. Size carefully. Depegs can widen suddenly; do not assume mean reversion.

Benefits

• Fast peg health check
• Pairs with slippage and converter tools
• Clear during volatile sessions
• Free and local

Pitfalls to avoid

• Oracles and CEX marks differ
• Peg can fail structurally
• Not a redemption guarantee
• Informational only

Noise versus stress

Tiny deviations are common. Persistent, widening discounts deserve caution. Use the peg checker as a dashboard number, then read issuer and market structure news.
