What Is Volatility Crush in Options?

# What Is Volatility Crush in Options?

A volatility crush occurs when implied volatility (IV) falls sharply, often after an uncertain event has passed. Because IV is an important option-pricing input, its decline can reduce option premiums even if the underlying moves in the trader's expected direction.

Why it happens

Before a major event, traders may pay more for options because the outcome is uncertain. Once the event passes, some uncertainty may disappear. If the market's expectation of future movement falls, IV can contract. This can happen around company results, policy announcements, elections, or economic releases, but it is not guaranteed.

A simplified example

An option trades at ₹120 before an event. After the event, the underlying moves in the expected direction, but IV falls and time value contracts. The option might fall to ₹95. These figures are illustrative, not a forecast. Actual prices depend on the underlying, strike, time remaining, volatility, rates, dividends where relevant, and execution costs.

Why buyers can lose despite being right

•The underlying move is smaller than the move already reflected in the premium.

•IV falls after the event.

•Time decay reduces extrinsic value.

•Delta changes as the underlying moves.

Buying a call or put before an event is therefore not purely a directional bet. The buyer also pays for the volatility priced into the contract.

What about sellers?

A seller may benefit from falling IV, all else equal, but selling before an event is not automatically safe. A large underlying move can overwhelm the benefit from lower IV. Short options can carry substantial or theoretically unlimited risk depending on the position.

Practical checklist

1.Compare IV with its own history and similar expiries.

2.Estimate what move the premium may imply; remember this is not a guarantee.

3.Model several scenarios: large move, small move, no move, and an IV decline.

4.Include transaction costs and liquidity.

5.Define maximum acceptable loss before entry.

Key takeaway

Volatility crush explains why being right about direction is not always enough. Option prices reflect both underlying movement and changing volatility expectations.

Frequently Asked Questions

Does volatility crush happen after every event?

No. IV can fall, remain elevated, or rise if uncertainty persists or new risks emerge.

Can an option lose value when the underlying moves in my favour?

Yes. Falling IV and time value can outweigh gains from the underlying move.

Is selling options before an event a guaranteed strategy?

No. A sharp move can cause large losses, and IV contraction does not eliminate gap, liquidity, or margin risks.
