Does the Underlying Asset’s Volatility Influence the Decision to Exercise an American Option Early?

Yes, volatility is a significant factor. Higher volatility increases the chance of future large price swings, which in turn increases the option's time value.

Since early exercise means forfeiting all remaining time value, higher volatility generally discourages early exercise, as the potential future gains from holding the option outweigh the immediate benefit of exercising.
