US-Israeli threats against Iran put the war premium back into crude and lifted only energy shares, while the S&P 500 slipped through its September floor and bonds sold with it. The risk is a weekend escalation hitting a tape short gamma into Tuesday's Fed.
Three things
- Oil is the shock that matters now. Fresh threats against Iran sent WTI up 3.8% and the oil majors to one-year highs, keeping the stagflation fear alive into the Fed.
- The S&P 500 lost its September floor on a quiet VIX. Dealers short gamma and vol-control funds near peak exposure mean any pickup in realized volatility forces selling, and only one of eight durable-low boxes is ticked.
- Credit is leading, not following. High-yield index spreads closed at their widest in 60 sessions, and the bottom rating tier is being sold first.
