What Is Implied Volatility?

Implied Volatility (IV) is the market's forward-looking estimate of price volatility extracted from options prices. High IV = market expects big moves. Low IV = market expects stability.

IV Term Structure shows how IV varies by expiry date:

Upward slope (contango): near-term calm, long-term uncertainty (normal)
Inverted (backwardation): near-term stress / upcoming event
