## Explain How Vega Measures an Option’s Sensitivity to Changes in Implied Volatility.

Vega is an option Greek that quantifies the change in an option's price for every one-percentage-point change in implied volatility. A high Vega means the option's premium is highly sensitive to IV fluctuations.

OTM options generally have a lower Vega than ATM options, but Vega is highest for options with a longer time to expiration, regardless of moneyness.

        "caption": "The image displays a close-up, low-key illumination of a dull, textured, teal-colored hemisphere resting against a narrow, polished metal blade extending from a larger, out-of-focus metallic structure on the left. The background is absolute black, emphasizing the material contrast and sharp structural lines. Conceptually, this arrangement powerfully illustrates the friction point between on-chain asset representation and the structured risk management employed in decentralized options trading. The teal element metaphorically represents the opaque nature of over-the-counter digital asset transactions or the absorbed premium of OTM puts and calls. The metallic structure signifies the immutable smart contract framework or the execution infrastructure handling high-frequency settlement. This visualization serves as an allegory for calculating real-time Greeks sensitivity, particularly delta hedging adjustments against fluctuating notional values in perpetual swaps or analyzing path dependency in exotic derivatives pricing, mirroring the granular, textured reality of blockchain consensus versus synthetic market exposure models like the Black-Scholes adaptation for cryptocurrency assets where continuous hedging is paramount for mitigating negative vega shifts."
