USDB's typical daily move over the last 90 days was 75 bps, steadier than 3 of 66 other USD stablecoins.
By default USDB sits beside its largest USD peer by current supply. Add more from the picker below the chart. Figures are in basis points: 100 bps = 1%.
Peg volatility is how much USDB's price swings around $1 from one day to the next: the standard deviation over 30 or 90 days. A stablecoin that sits steadily at $0.998 scores near zero. Largest deviation is the single day in the last 12 months furthest from $1, signed.
Median of peers, off by default, is the middle value among the peers currently shown; turn it on from the chart's controls.
The ranking counts every active USD stablecoin with at least two daily prices in the last 90 days.
Prices are daily closes at 00:00 UTC, from DeFiLlama with CoinGecko where DeFiLlama has no price. The chart beside this panel plots those same daily closes, so every figure in the table can be found on a line here. DeFiLlama quoted rounded and filled prices until 30 September 2025, so for USDT and USDC the closes before 1 October 2025 are the median of exchange closes instead, and a filled $1.0000 close is left out of the typical move and the largest move.
Stablecoins whose value rises by design, such as savings wrappers, are left out. Their price is a yield curve, not a peg.
Only USD stablecoins are compared. Other currencies are priced through a daily exchange rate fixed at a different time of day from the stablecoin's close. That gap shows up as the same false depeg on every stablecoin of the currency at once.

Daily close against the USD peg, in basis points. Drag the handles under the chart to zoom; a range button resets it. The axis spans -600 bps to +200 bps, set by the middle 98% of the closes in view, so one outlier does not flatten the rest. 2 closes sit beyond it, drawn on the edge with a triangle. The tooltip shows the true value.
The dotted vertical lines mark market stress events: days the whole market, or a stablecoin others hold as collateral, came under stress. Seeing every stablecoin on the same shock shows how each peg held. Only events with a published source are marked.
