Interest rate sensitivity quantifies how changes in interest rates affect the valuation of financial instruments, especially fixed-income products and derivatives. A common metric used to measure this sensitivity is duration, which indicates the percentage change in value for a one percent change in interest rates. Higher interest rate sensitivity exposes a portfolio to greater risk from monetary policy shifts.
Valuation
Changes in interest rate expectations directly impact the discount rate used in option pricing models, affecting the theoretical value of long-term derivatives contracts. The sensitivity of an option’s value to interest rates is measured by Rho, one of the options Greeks. As interest rates rise, call option values generally increase while put option values decrease.
Exposure
For derivatives traders, understanding interest rate sensitivity helps in managing portfolio exposure to macroeconomic policy changes. The impact on crypto assets and derivatives is particularly evident during periods of high inflation or central bank tightening cycles. Proper risk management requires continuous monitoring of this exposure, especially for positions with long durations.
