The US Federal Reserve is expected to raise the interest rates in coming months. Interest rate changes impact the overall economy, stock marketbond marketother financial markets and can influence macroeconomic factors. A change in interest rates also impacts option valuationwhich is a complex task with multiple factors, including the price of the underlying assetexercise or strike pricetime to expiryrisk-free rate of return interest ratevolatilityand dividend yield. Barring the exercise price, all other factors are unknown variables that can change until the time of an option's expiry.
It is important to understand the right maturity interest rates to be used in pricing options. Most option valuation models like Black-Scholes use the annualized interest rates. Interest rate conversions over different time periods work differently than a simple up- or down- scaling multiplication or division of the time durations. How can you convert it to annual rate? This is the annualized interest rate to use in any valuation model involving interest rates. For a standard options pricing model like Black-Scholesthe risk free one-year Treasury rates are used.
See related: The Black-Scholes Option valuation Model and The Importance of US Treasury Rates. It is important to note that changes in interest rates are infrequent and in small magnitudes usually in increments of 0. Other factors used in determining the option price like the underlying asset price, time to expiry, volatility, and dividend yield change more frequently and in larger magnitudes, which have a comparatively larger impact on option prices than changes in interest rates.
For a comparative analysis of how each factor impacts option prices, see Sensitivity Analysis For Black-Scholes Pricing Model. To understand the theory behind the impact of interest rate changes, a comparative analysis between stock purchase and the equivalent options purchase will be useful. We assume a professional trader trades with interest-bearing loaned money for long positions and receives interest-earning money for short positions. Rho is a standard Greek a computed quantitative parameter that measures the impact of a change in interest rates on an option price.
Similarly, the put option price will decrease by the amount of its rho value. The call price and put price has changed by almost the same amount as the earlier computed call rho 0. Fractional difference is due to BS model calculation methodology, and is negligible. In reality, interest rates usually change only in increments of 0. The other numbers are the same as in Case 1. As can be observed, the changes in both call and put option prices are negligible after a 0.
Over the course of the year, other factors can vary with much higher magnitudes and call option and put option difference 68 significantly impact the option prices. Similar computations for out-of-the-money OTM and ITM options yield similar results with only fractional changes observed in option prices after interest rate changes. Is it possible to benefit from arbitrage on expected rate changes?
Usually, markets are considered to be efficient and the prices of option contracts are already assumed to be inclusive of any such expected changes. See related: Efficient Market Hypothesis. Also, a change in interest forexpros oil chart usually has an inverse impact on stock prices, which has a much larger impact on option prices.
Overall, due to the small proportional change in option price due to interest rate changes, arbitrage benefits are difficult to capitalize upon. Options pricing is a complex process and continues to evolve, despite popular models like Black-Scholes being used for decades. Multiple factors impact options valuation, which can lead to very high variations in option prices over the short-term.
Call option and put option premiums are impacted inversely as interest rates change. However, the impact on option prices is fractional; options pricing is more sensitive to changes in other input parameters, such as underlying price, volatility, time to expiry, and dividend yield.

Yet the profit potential will remain the same as that with a long stock position. Hence, an increase in interest rates will lead to either saving in outgoing interest on loaned amount, or an increase in the receipt of interest income on saving account. Interest Disadvantage in Put Option : Theoretically, shorting a stock with an aim to benefit from a price decline will bring in cash to the short seller. Buying a put has similar benefit from price declines, but comes at a cost as the put option premium is to be paid.
This case has two different scenarios: cash received by shorting stock can earn interest for the trader, while cash spent in buying puts is interest payable assuming trader is borrowing money to buy puts. With an increase in interest rates, shorting stock becomes more profitable than buying puts, as the former generates income and the latter does the opposite. Hence, put option prices are impacted negatively by increasing interest rates.
