Understanding Options Vanna: How Implied Volatility Drives Dealer Delta

The Vanna Cross-Greek Derivative: dDelta / dVol

Vanna measures the sensitivity of an option's Delta to changes in Implied Volatility (IV):
$$\text{Vanna} = \frac{\partial \Delta}{\partial \sigma} = \frac{\partial \text{Vega}}{\partial S}$$

In cryptocurrency markets, when implied volatility spikes (e.g. ahead of a FOMC meeting or ETF announcement), Vanna forces dealers to buy or sell underlying futures contracts even if the spot price has not yet moved. Understanding Vanna allows quants to predict price movement purely from options volatility surface shifts.
