## Call option stochastic interest rate

In this paper, the call option price is evaluated based on linear investment strategy in order to hedge the risk actively in stock market with stochastic interest rate. The Vasicek model is used to describe the structure of interest rates.

The interest rate for the fixed interest rate model is set to be the interest rate from the stochastic interest rate model for the bond that matures when the option expires. we analyze the pricing of three-month call options and two-year call options. Except for ρ and T shown, other parameter values are the same as the ones in Table 1. Theorem 1 generalizes the BS call option pricing model to the case of stochastic interest rates. 14 In the BS model the price, C t T(, ), of the option is a function of the time to maturity, τ= −T t , the price of the underlying asset, S t(), at time t, its volatility, σ , and a constant risk-free rate. price of a European call option when the spot asset is correlated with volatility, and it adapts the model to incorporate stochastic interest rates. Thus, the model can be applied to bond options and currency options. 1. Stochastic Volatility Model We begin by assuming that the spot asset at time tfollows the diffusion dS(t) = tS dt + VSv _tiSdzl (t), (1) that the price of the underlying asset is the only source of uncertainty by allowing the. interest rate to be stochastic, and examine theoretically and empirically how this. additional source of uncertainty affects call and put option prices. An interest rate call option is a derivative that gives the holder the right, but not the obligation, to pay a fixed rate and to receive a variable rate for a specific period.

Dec 3, 2009 that stochastic volatility and stochastic interest rates have an impact 1the corresponding put option is immediately deduced by call put parity.

### An American call (put) option on a foreign currency or currency futures gives stochastic interest rates, and are based on Merton's (1973) stochastic interest.

Oct 21, 2009 stochastic interest rates makes the calibration process much harder: indeed, the for- ward PDE In particular for call options (h(x)=(ex −. K)+), it I'm trying to implement the Black-Scholes formula to price a call option under stochastic interest rates. Following the book of McLeish (2005), the formula is given by (assuming interest rates are nonrandom, i.e. known): Merton [2] considered dividend and stochastic interest rate into the option pricing model. Cox and Rose [4] used the alte[3] r- native stochastic process to discuss the option pricing model and considered the expanded formula of stock price that not include contidoes nuous sample path. In this section, we shall discuss the new option price, the Europe call option price, based on investment strategy with the stochastic interest rates under the Vasicek short model. Using daily data of the Nikkei 225 index, call option prices and call money rates of the Japanese financial market,a comparison is made of the pricing performance of stock option pricing modelsunder several stochastic interest rate processes proposedby the existing term structure literature.The results show that (1) one option pricing modelunder a specific stochastic interest ratedoes not significantly outperformanother option pricing model under an alternative stochasticinterest rate, and In this paper, the call option price is evaluated based on linear investment strategy in order to hedge the risk actively in stock market with stochastic interest rate. The Vasicek model is used to describe the structure of interest rates.

In this particular example, the strike price is set to 1. The Black–Scholes formula calculates the price of European put and call options. This price is consistent with
