前端波动率清空，相关性裂痕显现 - 期权简报
Core conclusion · Tlines extraction
The VIX fell 12.82% to 15.44, with the entire move concentrated in the front of the vol curve; VIX1D dropped 22.87% and VIX9D 23.05%. Saxo argues the index went quiet because components stopped moving together, not because they calmed. COR3M fell 11.40% while DSPX rose 2.88%, and SKEW held at 145.70. The Bank of Japan raised rates 25bp to 1.25%, sending the yen sharply lower.

Key arguments
- Front-end vol premium collapsed: VIX1D fell 22.87% and VIX9D 23.05%, against only 1.59% at one year.
- Correlation, not calm, explains the quiet index: COR3M fell 11.40% while DSPX rose 2.88%, and index options rank near a one-year low.
- The crash bid took no part in the unwind, with SKEW effectively unmoved at 145.70 through a 12.82% fall in the 30-day measure.
- Single-name and ETF flow was put-dominated (84.5% mega-cap, 91.5% rate funds) and mostly unreadable as direction.
Key numbers
- VIX
- 15.44 (-12.82%)
- VIX1D
- 13.12 (-22.87%)
- Front-month VIX future
- 17.92, +2.48 premium to spot
- COR3M / DSPX
- 11.58 (-11.40%) / 32.91 (+2.88%)
- SPX implied move to quarterly settlement
- 0.56% (~43 points)
Main risks
- The dispersion reading is a Saxo assessment, not a confirmed causal link; the quiet index could reverse if correlations re-couple.
- SKEW's stability means tail-risk protection was not repriced down, leaving it available if a shock arrives.
- Front-end vol, having collapsed, could just as quickly snap back around the BoJ press conference and US data.
Corresponding source evidence
Flat volatility and time decay alone would have left roughly 0.76%.
Expected move to today’s expiry, drawn around the Friday 11 September close, with the nearest listed strike at each bound.
On Wednesday the S&P 500 had spent 103% of the 101.65 point range priced around Friday’s close, to the downside.
