Introduction
The US-Israeli military campaign against Iran—including the decapitation strike on Supreme Leader Khamenei—has triggered a de facto closure of the Strait of Hormuz via insurance withdrawal. Brent crude has surged 26% this week. This note examines VIX behavior across three historical oil spike episodes to establish reference ranges for volatility pricing under the current crisis.
Methodology
Window selection based on oil price action: start when crude breaches +20% from pre-crisis levels, end when price retraces 50% from peak. This creates mechanically consistent comparison across different crisis types.
VIX Behavior Across Oil Spike Windows
Analog Relevance to Iran 2026
2008 Commodity Spike: Demand-driven rally with speculative positioning. VIX elevated but not extreme—gradual price moves produce lower vol than acute shocks.
Libya 2011: Physical supply disruption (1.6 mbpd offline). VIX remained subdued because crisis was geographically contained and SPR releases cushioned impact.
Russia-Ukraine 2022-23: Insurance and financial infrastructure as embargo mechanism—P&I clubs withdrew coverage before formal sanctions. This is the operative analog: the current Hormuz P&I withdrawal operates identically.
Implied VIX Reference Range
Iran duration cannot be derived from historical VIX data—depends on geopolitical resolution pathways.
Bottom Line
Current VIX at 25.4 sits above all three historical analog medians (17.9–23.5)—market is pricing acute crisis conditions
Consistent with Russia-Ukraine initial shock phase: first 30 days averaged 29.2 before mean-reverting to 24.5 over the full 307-day window
Base case if Iran follows this template: VIX gravitates toward 22–25 central tendency as markets adapt, with periodic spikes into the 30s on escalation headlines
Key variable is duration:
Shorter resolution (Libya template) → faster VIX normalization
Prolonged Hormuz disruption (Russia-Ukraine template) → elevated vol sustained for 6–12 months
