Volatility Crush
A volatility crush is a sharp drop in implied volatility that deflates option prices. Learn what triggers it, why it traps buyers, and how it rewards premium sellers.
A volatility crush is a sharp, sudden drop in implied volatility that deflates option prices across the board. When it hits, options that were expensive become cheap in a hurry, and anyone holding them long feels the air go out of their position.
It is the broad name for the phenomenon. The most famous example, the collapse right after an earnings report, has its own page as IV crush. Let me show you the wider picture.
The Balloon Deflating
Implied volatility inflates like a balloon whenever the market braces for uncertainty, and it deflates the moment that uncertainty clears. A volatility crush is that deflation happening fast.
The trigger does not have to be earnings. Any resolved uncertainty can do it: a product launch, a court ruling, a Fed decision, a drug trial result, even the simple passing of a nervous, event-heavy week. Before the event, fear is priced in and options are fat. After it, the mystery is gone, vega drags every option down, and the balloon empties.
Watch It Bite
Apple is at $200 the day before a major product announcement. Implied volatility is elevated, and a $200 call is trading at $6 a share, fat with anticipation.
The announcement lands, and Apple ticks up to $202. You were right about direction, if only mildly. But implied volatility collapses now that the news is out. That $6 call, despite the higher stock, sags to about $4 a share. The volatility crush pulled more value out of the option than the small move up put back in.
This is the trap. A buyer can read the event correctly and still lose, because the crush drains the vega they paid for. To win through the event, the move has to be big enough to overcome the deflation.
Who It Helps
The crush that punishes buyers is exactly what premium sellers are hunting for.
Sellers open positions when volatility is high and options are inflated. When the crush arrives, the options they sold deflate, and they buy them back cheaper or let them expire. Selling into elevated volatility before a known event, then riding the crush down, is a classic income setup behind trades like the short strangle and cash-secured put.
The opposite force, when fear rises and IV inflates instead, is a volatility expansion. The two together are the breathing of the options market.
- A volatility crush is a sharp drop in implied volatility.
- Any resolved uncertainty can trigger it, not just earnings.
- It hurts buyers, who can be right on direction and still lose.
- It rewards sellers who sold inflated premium beforehand.

Bottom Line
A volatility crush is the balloon of fear deflating in a rush. Options that were pricey on uncertainty lose value the instant the mystery clears, and buyers who paid up can lose even when they call the direction right.
It is the same force whether it follows earnings, a Fed meeting, or any event that resolves. Buyers need a move big enough to beat the deflation. Sellers are betting on exactly that collapse.
Keep going: the classic earnings version is IV crush, the opposite force is volatility expansion, and the Greek behind it is vega.
