Dealer VEX Surface (Spot: $600)

25 x 15 grid

Call Vega (Blue)

Strikes dominated by call open interest. Dealers short these calls are short vega here — if implied volatility rises, they face mark-to-market losses and may need to buy options to re-hedge, amplifying vol moves.

Put Vega (Red)

Strikes dominated by put open interest. Dealers short these puts are also short vega — concentrated put vega below spot is a key driver of volatility skew and the fear premium in downside options.

Vega Walls

Large VEX concentrations mark strikes where a volatility spike will force the most dealer re-hedging. These levels often coincide with high-OI strikes and act as vol attractors — the market tends to mean-revert toward maximum vega concentration.
