IV Term Structure

ATM Black-76 implied volatility across expirations. Contango (rising) is normal; backwardation (inverted) signals a near-term event.

Understanding Futures Options Skew

Options skew measures the difference in implied volatility between out-of-the-money puts and equidistant calls. The 25-delta skew compares the IV of a 25-delta put to a 25-delta call. For options-on-futures, IV is solved with the Black-76 model on the futures price.

Steep skew: The market is pricing in higher demand for downside protection. In commodity and rate futures this often reflects supply, delivery or policy risk concentrated on one side of ZB.

Flat or inverted skew: Can indicate squeeze positioning, bullish sentiment, or heavy call buying driving up upside IV.

Term Structure Regimes

  • Contango (normal): Longer-dated options have higher IV than shorter-dated. Reflects time-value premium and normal uncertainty growth.
  • Backwardation (inverted): Near-term IV exceeds far-term. Signals an imminent catalyst: FOMC, CPI, NFP, or other binary macro event.
  • Flat: Uniform IV across the curve. Can indicate low conviction or a transition between regimes.
