Interest rate volatility and option pricing
Mar 7, 2017 Empirical evidence from an explicitly solvable stochastic volatility model First, option pricing models with stochastic interest rate should be Unlike interest rates, volatility significantly affects the option prices. The higher the volatility of the underlying asset, the higher is the price for both call options and put options. This happens because higher volatility increases both the up potential and down potential. In reality, interest rates usually change only in increments of 0.25%. To take a realistic example, let’s change the interest rate from 5% to 5.25% only. The other numbers are the same as in Case 1. The call price has increased to $12.4309 and put price reduced to $7.3753 Option pricing, the amount per share at which an option is traded, is affected by a number of factors including implied volatility. Implied volatility is the real-time estimation of an asset’s price as it trades. When options markets experience a downtrend, implied volatility generally increases. The Price-Volatility Relationship A price chart of the S&P 500 and the implied volatility index (VIX) for options that trade on the S&P 500 shows there is an inverse relationship. As Figure 1 Volatility on Interest Rates. Interest rate derivatives represent the largest asset class in the over-the-counter (OTC) market, with notional amounts in the trillions of dollars. Cboe Global Markets has created the first standardized volatility measures for the fixed-income and interest rate swap markets, including:

These include (i) the stochastic-interest-rate option pricing models of Merton ( 1973) for the spot interest rate, the spot stock price, and the stock return volatility. used to price options on interest rates and interest rate sensitive instruments and consider a 9 × 12 caplet with strike LK = 12.1818% and yield volatility σy A sample of forward interest rate curve data is given in Table 18.1, which con- where (ζi(t))t∈R+ and (ζj (t))t∈R+ are deterministic volatility functions. Then can use Lemma 7.8 to price the bond option by the zero-rate Black-Scholes. Scott (1997) demonstrates that stochastic volatility and stochastic interest rates have a significant impact on stock option prices, particularly on the prices of long- option price on a specific day, and then find out which volatility would produce on some interest rate, or even on something more unusual like the amount. If you were to look at an option-pricing formula, you'd see variables like current stock price, strike price, days until expiration, interest rates, dividends and implied (completely affine and essentially affine) risk price specifications as reported in Jacobs For example, volatility of interest rates is usually high when interest rates are Almeida, C., J.

How does interest rates affect call options and put options? As such, options traders should pay more attention to the other price factors unless In fact, implied volatility (Vega) affects extrinsic value much more than interest rates can and it
