## Rho

Rho measures the sensitivity of an option's price to changes in the risk-free interest rate. While often less significant than delta, gamma, or vega in short-term trading, rho becomes important for long-dated options or in environments with rapidly changing interest rates.

It indicates how much the price of an option will change for a one-percent change in the interest rate. For call options, rho is generally positive, meaning higher interest rates increase the call price, while for put options, rho is generally negative.

In the context of decentralized finance, interest rates are often tied to lending protocols and staking yields, making rho a relevant factor for complex derivative strategies. Traders monitoring long-term positions must account for potential interest rate fluctuations to accurately value their options and assess their overall risk exposure.
