ETH: Stablecoin Hours Off Peg (More Than 0.5% From $1)
Shown as its 2019–2022 sample; the latest readings and full history are included with Plus.
For each major dollar stablecoin, the number of hours each day in which its exchange price was more than 0.5% away from $1, either side.
Why use it. How often a coin slips: one bad hour can be a thin market, while hours off peg on several days in a row are a coin under real pressure. How to read it. Zero is a coin holding its peg all day. The count is of counted hours only, so a coin whose markets are thin can show zero simply because few of its hours traded $25,000.
Calculation. Each counted hour whose price was below $0.995 or above $1.005 adds one to its UTC day; the latest day is a partial. Computed by CryptoKeyhole from Kraken's and Coinbase's public market data: each stablecoin's own US-dollar market, hour by hour. A market's hour counts only when at least $25,000 traded in it, because several of these markets trade a few hundred dollars an hour and a single stray trade would look like a depeg; an hour with no counted market is left empty. The price of the hour is the volume-weighted average of the counted markets' hourly average prices (Kraken's own volume-weighted price; for Coinbase, which publishes none, the mean of the hour's open, high, low and close). History: Kraken's public data gives its last 30 days, from 9 October 2026; Coinbase's goes back to each market's listing (USDT from May 2021, USDS from July 2025, USD1 from August 2025). Prices on exchanges, not on chain: a coin can trade differently in on-chain pools.
