Which measure is associated with risk management in relation to interest rates?

The measure associated with risk management in relation to interest rates is Rho. Rho quantifies the sensitivity of an option's price to changes in interest rates. Specifically, it measures the expected change in the option's price for a 1% change in the interest rate. This is particularly important in fixed-income markets and for options on bonds, as interest rates can significantly affect the value of these instruments.

Understanding Rho is crucial for managing exposure to interest rate fluctuations, especially for traders and investors who deal with options or fixed-income securities. Effective risk management involves monitoring how changes in interest rates can impact portfolio values and making adjustments accordingly to mitigate risks.

The other measures listed—Vega, Theta, and Delta—are more closely associated with other types of risk. Vega relates to changes in volatility, Theta pertains to time decay, and Delta measures sensitivity to changes in the underlying asset's price. While all these measures play important roles in risk management, Rho specifically addresses the implications of interest rate changes.
