How Do Interest Rates Affect the Value of a Call Option (Rho)?

Rho measures the sensitivity of an option's price to changes in the risk-free interest rate. For call options, an increase in interest rates generally increases their value because the present value of the strike price (the money to be paid later) decreases.

Conversely, an increase in rates generally decreases the value of put options.
