Rho Greek Exposure

Rho Greek exposure measures the sensitivity of an option's price to changes in the risk-free interest rate. As interest rates rise, the cost of carry for long positions increases, which impacts the pricing of both calls and puts.

In the crypto derivatives market, where interest rates are often tied to decentralized lending protocol yields, rho becomes a critical risk metric. Traders must account for how shifts in these underlying rates affect their delta-hedged portfolios.

High rho exposure can lead to unexpected losses if interest rate environments change rapidly. It is a technical component of the Black-Scholes model that is often overlooked by retail traders but managed rigorously by institutional market makers.
