Bitcoin options turn put-rich as short-dated volatility falls
Bitcoin’s two-week options shifted from call-rich to put-rich over the weekly observation window ending on 26 September. Derivasys data show Bitcoin two-week RR25, the implied-volatility difference between comparable calls and puts, falling 3.12 volatility points to minus 1.14%. This was a large move against its recent comparison history. Bitcoin one-week ATM IV also fell 3.87 volatility points to 30.64%, placing the skew reversal alongside cheaper short-dated volatility. The relative put-side shift does not establish that put implied volatility rose outright. A valid seven-day intraday realised-volatility comparison was unavailable.

Bitcoin’s $80,000 test ends with short-dated volatility sharply lower
Bitcoin’s week was shaped by a renewed institutional bid, an abrupt change in the US rates narrative and a large derivatives expiry. Treasury plans for bigger bond buybacks helped weaken the dollar and revive the debasement trade, while strong ETF inflows carried Bitcoin through $80,000. Inflation data and Kevin Warsh’s Jackson Hole debut later restored some policy caution. The options market traced the same unsettled path: front-end volatility rose sharply, reversed just as quickly and ended the week 8.75 points lower at the one-week tenor.
