The Pricing of Cross currency Equity Swaps and Swaptions

Wang, Ming-chieh 27 July 2000 (has links)
Abstract The valuation of equity swap under the condition of risk neutral is similar to the forward interest rate swap with the same period. Therefore, its valuation formula is consistent to interest rate swap model in the traditional methods. But it is not the same as in pricing the cross-currency equity swap. The dymanic prices of foreign stock index and exchange rate, and the correlation coefficients between exchange rates and foreign assets also affect the swap rate. In this paper, we extend Chance and Rich(1998)¡¦s valuation formula of equity swaps, and apply Amin (1991)¡BAmin and Bodurtha(1995)¡BLin(1997)¡¦s dymanic prices of assets in discrete time period. To derive the risk neutral valuation formula of equity swap, it uses the method of transfer probability measure. This study finds the expected return of foreign stock index in the no arbitrage condition, in addition equal to foreign forward interest rate with the same period , must be add a correction term to reflect the exchange rate risk and the transfer of forward martingale measure. This paper also derives the pricing formula of equity swaptions¡Bcaps¡Bfloors¡Bvariable notional principal and blended equity swap. Finally, we find the volatility of foreign forward interest rate is the most important factor of pricing the swap rate from numerical simulation. And if the correlation of the volatility of exchange rate and foreign stock index¡Bthe correlation of the volatility of exchange rate and foreign forward interest rate are negative, the swap rate will be higher.

隨機利率下之資產交換-跨通貨股酬交換與利率交換的評價與避險 / Asset Swap Under Stochastic Interest Rate__The Pricing and Hedging of Cross-Currency Equity Swap and Interest Rate Swap

姜碧嘉, Chiang, Bi-Chia Unknown Date (has links)
雖然跨通貨股酬交換在國際投資市場扮演著重要的角色,但文獻上關於股酬交換評價模式的相關探討並不多,且多集中於國內市場或以本國貨幣做為支付幣別的股酬交換。對於跨通貨股酬交換而言,其評價模式較國內股酬交換之評價模式複雜許多,如何將影響其價值之股價指數、匯率與利率此三個主要因子間的交互相關性同時加入考量,即是此產品之評價過程的重點。 本文在完全市場的假設下,同時放寬傳統評價方法之各變數之相關係數為固定值的假設,提出一新的股酬交換評價方法,即以『兩階段兩步驟』之較具經濟含意的複製方式,推導出股酬交換的一般化評價公式。透過此複製方法,可更清楚得知股酬交換於存續期間的價值變動,更可進一步求得其避險方式,以提供股酬交換交易商在面臨不對稱風險(mismatch risk)時的避險方法。而本文的第二個貢獻在於,將本文所提出之『兩階段兩步驟』的複製方法應用於利率交換的評價上,推導出跨通貨利率交換的一般化評價模式,以進一步比較股酬交換與利率交換此兩種商品的差異性,並試圖釐清市場上對於跨通貨股酬交換評價上的誤解。 與傳統評價公式最大的差異在於:本文評價公式額外考慮了一修正項,複製投資組合可藉由此修正項,對未來各參數間的變動隨時做出調整,以使投資組合能完全複製跨通貨股酬交換的價值。 本文發現,對於國內投資人支付固定利率,以交換B市場的股價指數報酬,且以C國的貨幣做為支付幣別的跨通貨股酬交換而言,其價值除了受到當期利率期間結構的影響外,在期初或每期交換後,其價值與股價指數無直接關聯,但在兩支付間,其價值則會受到當時股價指數與前期股價指數之相對比例的影響。同時,C國對本國的未來匯率並未直接影響跨通貨股酬交換的價值。且若假設各國遠期利率的波動度為零下,則當B國股價指數與C國對本國的匯率呈現正關係或當B國股價指數與B國對本國的匯率呈現負關係時,跨通貨股酬交換的價值愈大。另外,市場上投資人通常誤認股酬交換的價值等於利率交換價值,對於股酬交換與利率交換的比較,本文發現在大多數的情況下,股酬交換的價值與利率交換的價值並不相等。
