Volreport for Week 30, 2026 (Jul 20 – Jul 24)
SOL screens cheapest to own this week (IV−RV -7), while SPCX is the most expensive (+10). 25Δ risk-reversals stay negative on SOL, BTC, ETH, XRP — the market paying up for downside, leaving calls the cheaper wing. Tokenised gold (XAUT) prints its own ~16 vol — a calm, low-beta anchor against the crypto names.

Reading the tiers below: the 25Δ Risk Reversal
A 25Δ risk reversal compares two equally out-of-the-money options — a 25-delta call and a 25-delta put — and takes the difference in their implied vol. A negative number means puts cost more: the market is paying up for downside protection, and calls are the relatively cheap wing. A positive number is the reverse — calls cost more, puts are the cheap wing.
Tier 1 — Liquid listed options
BTC gained 0.3% on the week; 30-day realized cooled 43→38. Own-book 30-day implied at 33 screens 5 vols under realized — vol is cheap to own here; 25Δ risk-reversal -4.7 — puts pricier (downside bid).
ETH gained 0.8% on the week; 30-day realized cooled 57→51. Own-book 30-day implied at 47 screens 4 vols under realized — vol is cheap to own here; 25Δ risk-reversal -3.5 — puts pricier (downside bid).
Tier 2 — Alts & reference-anchored
SOL fell 1.1% on the week; 30-day realized cooled 66→58. Own-book 30-day implied at 50 screens 7 vols under realized — vol is cheap to own here; 25Δ risk-reversal -5.1 — puts pricier (downside bid).
XAUT gained 1.2% on the week; 30-day realized cooled 24→21. Own-book 30-day implied at 16 screens 5 vols under realized — vol is cheap to own here; 25Δ risk-reversal near flat (+0.2) — calls and puts level.
XRP gained 0.2% on the week; 30-day realized cooled 50→48. Own-book 30-day implied at 49 is roughly balanced against realized; 25Δ risk-reversal -3.8 — puts pricier (downside bid).
Tier 3 — Tokenized RWAs & pre-IPO
SPCX fell 7.9% on the week; 30-day realized cooled 89→78. Own-book 30-day implied at 88 sits +10 over realized — more expensive, leans toward selling premium; 25Δ risk-reversal near flat (+0.0) — calls and puts level.
