固定期信用違約交換之評價與避險分析

陳俊豪 Unknown Date (has links)
固定期信用違約交換(Constant Maturity Credit Default Swap)是移轉固定年期信用違約交換信用價差(CDS Spread)變動風險的信用衍生性金融商品,目前僅Brigo(2005)以及Krekel and Wenzel(2006)探討固定期信用違約交換的評價,也各自推導出近似封閉解,但對於相關參數之估計以及避險參數並沒有涉及,因此本研究將利用歷史資料估計Krekel and Wenzel(2006)評價公式中的參數,讓評價模型更加完備,並求算避險參數,提供發行商與投資人避險資訊。 本文利用目前信用違約交換(Credit Default Swap)市場中各到期日流動性較高的美國Eastman Kodak Company公司債作為標的物,發行一檔固定期信用違約交換,並利用現有市場資訊估計模型中的參數。在避險實證上,本文利用標的物債券信用價差曲線的變動,對固定期信用違約交換契約價值以及五年期及十年期信用違約交換契約價值的影響,建構了一個避險投資組合,使得避險後總投資組合價值波動減少。 / Constant Maturity Credit Default Swap (CMCDS) is one of the credit derivatives, whose function is to circumvent the fluctuating risk of CDS Spread. Brigo (2005) and Krekel and Wenzel (2006) focused on not only probing into the evaluation of the CMCDS but also deriving the approximated closed-form solution in their recent research separately. However, they seldom concern the hedging approach and the estimated parameters of pricing model, which could be major variable in the measurement. This paper is aiming to calculate the history data of hazard rate to estimate the parameters by using the formula from Krekel and Wenzel (2006) and compute the hedging approach of the pricing model to make it become more complete and provide the hedging information for both financial institutions and investors. By using the corporation bond of Eastman Kodak Company which with higher liquidity and various maturity as the main reference asset to issue a CMCDS and utilizing the current available market data to estimate the parameters of the pricing model to evaluate the value of the product, I find that the various credit spread curve of reference bond will influence the value of CDS and CMCDS and try to structure a hedging portfolio to eliminate the fluctuation of the product.

利用最小平方蒙地卡羅模擬法評價美式信用違約交換選擇權 / Pricing American credit default swap options with least-square monte carlo simulation

葉尚鑫, Ye, Shang Shin Unknown Date (has links)
歐式信用違約交換選擇權通常都以短天期較富流動信,造成這樣情形的原因很可能是因為長天期的信用違約交換選擇權必須承擔標的公司的倒閉風險。美式信用違約交換選擇權讓持有者可以在選擇權到期以前履約,這使得持有者可以只注意信用違約交換溢酬的變動,而不必擔心標的公司的倒閉風險。在這篇論文當中,我們結合最小平方法以及單期信用違約溢酬模型評價美式信用違約交換選擇權,其中單期信用違約溢酬模型是由布瑞格在2004年所發表的模型。本篇論文評價方法的最大優點在於此方法類似於利率理論的市場模型,因此我們可以利用類似的想法評價任何與信用違約交換合約相關的信用衍生性商品。 / The most liquid European CDS options are usually of short maturities. This may result from that options with longer maturity have to bear more default risk of the reference company. American CDS options allow the holders to exercise options before option matures so that they can focus on spread movements without worrying about default risk. In this paper, we price American CDS options with one-period CDS spread model presented by Brigo (2004). The primary advantage of this model is that it is similar to LIBOR market model in interest rate theory. Therefore, path-dependent CDS-related products can be easily priced with familiar ideas.

能源與貴金屬連結及利率連結之結構型商品評價與分析─以中國銀行結構性存款為例 / The Pricing and Analysis of Commodities-Linked and Interest Rate-Linked Structured Products: The Case Study of Structured Deposits Launched by Bank of China

蔡昌甫, Tsai,Chang Fu Unknown Date (has links)
在過去二到三年之中,能源、金屬、軟性商品等原物料價格漲勢強勁,成為市場上最炙手可熱的商品。然而,原物料價格漲升為全球帶來了通膨隱憂,世界各國紛紛採用各種貨幣政策和財政政策試圖緩解通膨壓力。其中,利率政策即是相當重要的一環。在這樣的背景之下,是否對於能源、貴金屬和利率衍生性商品的設計和定價上產生影響,值得進一步檢視。因此,本論文選擇以中國大陸的原油與黃金連結複合式選擇權,以及利率(HIBOR)連結可贖回每日區間計息等兩種結構性存款作為研究個案,以財務工程的理論模型為中國銀行的金融創新產品作評價與分析。 在原油與黃金連結複合式選擇權部分,分別假設金價和油價服從幾何布朗運動(Geometric Brownian Motion)推導出封閉解,以及Schwartz的一因子均數回歸模型,採蒙地卡羅模擬法模擬標的資產之價格路徑並以之估算商品理論價值和發行機構利潤,之後則就避險參數和商品預期收益率作分析。在利率連結可贖回每日區間計息結構性存款部分,由於具有發行機構可提前贖回的特性,本論文採用LIBOR市場模型(BGM Model)為評價基礎,先利用市場報價資訊計算期初遠期利率及進行參數校準,再以蒙地卡羅模擬法模擬遠期利率路徑,最後以Longstaff and Schwartz(2001)提出的最小平方蒙地卡羅法(LSM)計算商品理論價值和發行機構利潤。 除估算商品理論價值以檢視中國銀行的商品定價合理性之外,本文也針對中國大陸的外匯和利率政策對金融機構在商品設計方面的影響作分析,最後則分別就財務工程與金融創新以及總體政策與金融市場兩方面提出結論與建議,以供各界參酌。 / The prices of physical commodities have risen a lot and led to pressure of inflation for several years. Many countries over the world have tried hard to tackle inflation threat with monetary and fiscal policies. Under this circumstance, the design and pricing of structured products should be affected. Therefore, the oil and gold-linked and interest rate-linked structured deposits launched by Bank of China are selected to be the case study in this thesis. Prices of the underlying assets are assumed to follow Geometric Brownian Motion, and the close-form solution of the oil and gold-linked structured deposit embedded with compound options is derived. Moreover, Schwartz’s One-Factor Mean Reversion Model is adopted to derive the fair value by simulation. In addition to the fair value and issuer’s profit, the expected rate of return, hedge parameters (Greeks) and model difference are presented in this thesis. As for the interest rate-linked Callable Daily Range Accrual Deposit, the thesis presents the steps of pricing by simulation. LIBOR Market Model (BGM Model) is adopted to derive the fair value of Callable Range Deposit with Least Squares Monte Carlo approach. Besides, the design and pricing of structured products are actually influenced by those policies in relation to interest rates and currencies adopted by government of Mainland China. The influence is discussed in the thesis as well. Eventually, the conclusions and suggestions are made with respect to macroeconomic policy and financial market as well as financial innovation.

LMM利率模型下可取消利率交換評價與風險管理 / Cancelable Swap Pricing and Risk Management under LIBOR Market Model

廖家揚, Liao, Chia Yang Unknown Date (has links)
許多公司在發行公司債的時候,會給此公司債一個可提前贖回的特性,此種公司債稱為可贖回公司債(Callable Bond),用來規避利率變動風險的金融商品也與我們熟知的利率交換不同,稱為可取消利率交換(Cancelable Swap)。其實可取消利率交換可以拆解成百慕達利率交換選擇權(Bermudan Swaption)加上利率交換,由於利率交換之評價較簡單也有市場一致的評價方法,因此百慕達利率交換選擇權便成為評價的重點。 評價的部分,由於百慕達式的商品有提前履約的特性,造成其封閉解不存在,因此需要利用其他的近似解或是數值方法來求它的價格。由於本文採用BGM(1997)的市場利率模型(Libor Market Model),其高維度的性質導致數狀方法與有限差分法使用起來較無效率,因此本文選擇使用蒙地卡羅法做為評價的方法,同時利用Longstaff and Schwartz(2001)的最小平方蒙地卡羅法(Least Squares Monte Carlo Method)來解決提前履約的問題。 最後,本文將採用2種利率波動度假設與2種不同利率間相關係數的假設,共4種組合,在歐式利率交換選擇權的市場波動度下進行校準,使用校準出來的參數進行評價來得到4種價格。再進行商品的敏感度分析(Sensitivity Analysis)和風險值(Value at Risk)的計算。

結構型金融商品之評價與分析-固定期限交換利率利差連動債券 / Evaluation and Analysis of Structured Financial Products-100% Principal Protected Leveraged Callable CMS Spread Note

李健維 Unknown Date (has links)
次級房貸風暴使得包裝複雜的衍生性金融商品紛紛遭受波及後,目前結構型金融商品的條款設計將朝簡單化和透明化的趨勢發展,有助於全球金融市場的效率性、完整性與穩定性。本文從市場上選擇具代表性的利率結構型商品,應用模型來推導商品的價格,並深入分析商品的報酬與風險型態。 本文分析的個案商品為全球知名的匯豐銀行所發行之十年期「固定期限交換利率利差連動債券」,在評價上將採用LIBOR市場模型,利用市場上既有的資料求算出期初遠期利率,並校準模型所需的參數化波動度函數與相關係數函數,建立與市場一致的利率期間結構與利率波動度期間結構。模擬路徑時應用最小平方法蒙地卡羅來求得該商品發行之期初價格,此外,亦採用反向變異法加速收斂效果,並針對商品的條款設計作拆解與分析。最後,本文探討了發行機構發行商品之風險與避險策略,並且從投資人之報酬及風險層面作詳盡地剖析。

信用及利率衍生性商品之評價與分析--以信用連結票券及利率交換為例

林淳瑜 Unknown Date (has links)
近年來由於金融自由化的發展,台灣已陸續開放新金融商品,除了股權相關的新金融商品之外,也陸續開放利率相關的新金融商品,如新台幣利率交換、新台幣利率選擇權、債券遠期交易、債券選擇權等。在信用衍生性商品市場方面,我國銀行從2002年底開放承做信用衍生性商品,目前正準備開放證券商承做。隨著金融國際化及自由化,未來將會從國外引進更新穎的金融商品,使金融市場更為完備。 本文以Hull – White利率模型及LIBOR市場模型為架構,藉由數值方法評價分析兩個衍生性商品──信用連結票券及利率交換。首先在信用連結票券方面,運用Li(1998)建立信用價差曲線(Credit Curve),將之應用至Hull – White三元樹,評價信用連結票券之價值,並作敏感度分析與避險參數分析。其次在利率交換方面,由於投資人端連結「雪球型」的支付型態,為路徑相依商品,故使用LIBOR市場模型以蒙地卡羅模擬法(Monte Carlo)進行評價與分析,再進行發行者損益兩平分析及情境分析。最後針對兩個商品的評價結果作結論,分析發行者及投資人的利潤及避險,並給予後續研究者模型改進之建議與方向。
