How Does Implied Volatility Affect the Delta of an At-The-Money Option?
Increased implied volatility causes the Delta of an At-The-Money (ATM) option to move closer to 0.5 (for calls) or -0.5 (for puts). Higher volatility increases the probability of the underlying price moving significantly in either direction, making it more likely that the option will expire both In-The-Money and Out-of-The-Money.
This effect "flattens" the Delta curve, pushing the ATM Delta closer to the theoretical 0.5 value, and slightly pulling the ITM and OTM Deltas closer to 0.5.
