The Session

The S&P 500 fell 0.69%, or 53.30 points, to 7,691.76 on its third straight decline, as a bond selloff sapped risk appetite per Bloomberg Markets. The VIX rose 0.65 points to 15.84, a 0.4 daily-sigma lift that left it in the Low regime with the curve in contango — a modest response relative to the equity drop and consistent with where realised volatility has been running. VXN climbed to 22.56 and VSTOXX to 13.36, while OVX and GVZ both declined. Risk appetite stayed elevated at 1.28 standard deviations above neutral, though the score eased 0.19. One-month skew widened 0.38 points to 4.15, and options priced a 0.59% expected move into tomorrow's expiry.

Today's Focus

Neutral · 5 components

0-100, the mean of each component's own one-year percentile, oriented so higher is more volatility stress. Each component is ranked against its own past year, so a reading can be calm in absolute terms and still sit high against its own recent range.

What to watch

FOMC minutes are due tomorrow at 14:00. Whether the VIX holds the 15–20 band — it has stayed there on 82.9% of 1,696 historical sessions — and trade inside the 46-point implied move would keep the picture intact.
