Nikkei jumps 4% and VIX plunges in a risk-on session

The session closed with a clear risk-on tone. Wall Street advanced broadly — the S&P 500 gained 0.70% (z=0.8), the Nasdaq 1.00% (z=0.8) and the Dow Jones 0.53% (z=0.6) — while implied volatility collapsed: the VIX fell 17.3% intraday, from 20.7 to 17.1. In Asia, the Nikkei stole the show with a 4.03% jump (z=2.2 versus the past year), the most extreme signal of the day. With the yield curve uninverted, credit stable and the dollar barely moving, the overall picture points to a day of relief after recent bouts of nervousness.

The Nikkei's +4.03% surge stands out among global equities and came alongside a sharp drop in the VIX, which fell from 20.66 to 17.09 (−17.3%) in a single session. European moves were muted: the FEZ rose 0.10% and the EWP 0.07%, while the EWG slipped 0.07%. In commodities, oil advanced firmly: WTI +1.29% and Brent +1.22%. In currencies, EUR/USD edged down just 0.01% and USD/JPY added 0.12%, while the broad dollar index fell 0.16%. Gold slipped 0.06%. Crypto was the day's weak spot: bitcoin fell 2.94% (z=−1.2), ether 2.93% (z=−0.9), solana 2.22% (z=−0.6) and XRP 1.96% (z=−0.6).

The yield curve remains uninverted: the 10-year–2-year spread sits at 0.47 percentage points, 693 days since the last crossing, while the 10-year–3-month spread stands at 0.92 points, 287 days since its own. Credit shows no strain: the high-yield spread is at 2.84 percentage points (z=−0.2 versus the past year). The broad dollar trades at 120.71, 0.55% above its 50-day moving average (120.05). The VIX term structure remains in contango — a VIX/VIX3M ratio of 0.88, down from 0.96 the prior session — a level still consistent with calm in the options market. The Brent-WTI spread widened to $5.45, above its historical median of $3.5, having risen $2.34 over the past 20 sessions. 30-day correlations show some breakdown of usual patterns: sp500–UST10Y moved from −0.71 to −0.32, and sp500–broad dollar from −0.70 to −0.20, while sp500–WTI held steady at −0.35 (previously −0.35). Market breadth is moderate: 58.8% of the 17 tracked assets trade above both their 50-day and 200-day moving averages.

The Brent-WTI spread keeps widening and now trades above its historical median of $3.5, having risen $2.34 over twenty sessions to the current $5.45. The 30-day correlation between the S&P 500 and the broad dollar has weakened to −0.20, close to flipping into positive territory after starting at −0.70; a sign reversal would break a historically stable relationship between equities and the currency. The VIX term structure remains in contango (ratio 0.88), but it moved quickly from 0.96 in the prior session, reflecting how abrupt the volatility drop was.
