The day across the three live Derivasys markets.
One-week implied volatility rose across all three markets. The largest one-week implied-versus-seven-day realised gap was in BTC, at -6.66 volatility points.
This is a comparison, not a pooled surface: each asset keeps its own forwards, expiries, SVI fit and realised-volatility history.

Bitcoin gains without a volatility chase
Bitcoin rose 1.55 per cent over the 24-hour window, but the options market did not chase the move: one-week implied volatility added only 0.19 points and one-month volatility slipped. Skew became less defensive, while seven-day realised volatility remained above the one-week implied measure. The news backdrop offered useful institutional and on-chain context, though neither item provides a convincing explanation for the restrained repricing.

Bitcoin gains without a volatility chase
Bitcoin’s forward rose as the front of the volatility curve held broadly steady and short-dated skew moved back towards calls, leaving the day more orderly than the spot advance alone might suggest.
Macro: The weekend produced no fresh scheduled macro release that met the report’s relevance threshold; the latest completed US-session context therefore remains Friday’s close.
Crypto: Sber’s proposed use of Bitcoin, Ether and USDT as collateral added an institutional-adoption thread, while unusually active old Bitcoin wallets supplied a separate on-chain risk marker; neither was treated as the cause of the surface move.
