Bitcoin (BTC) was reported at a 28-day realized-volatility reading of 1.2% on Oct. 21, near its 2026 low as trading remained subdued before a U.S. rate decision and midterm elections.
Realized volatility summarizes how much an asset’s price moved during a past period. This reading covers 28 days; it does not estimate how far Bitcoin may move next.
From Sept. 21 through Oct. 19, Bitcoin traded inside the high-low range set by its Sept. 21 daily candle. By Oct. 19, the 28-day measure was nearing levels last seen in mid-August.
An earlier EconoTimes comparison of Bitcoin’s realized volatility reported 43% annualized volatility over the previous year. The figures cover different periods, so they describe separate windows of price movement.
The Federal Reserve is scheduled to meet Tuesday and Wednesday, Oct. 27-28, with its rate decision expected Wednesday. U.S. midterm Election Day is Nov. 3.
