关于CreditMetrics模型的计算举例

关于CreditMetrics模型的计算举例

资产组合的VAR 计算步骤(一)对于单个资产VAR 的计算Credit Metrics 组合模型中,按以下步骤计算单个资产VAR:第一步:确定信用等级评价系统,可以在给定某一公司的信用质量及给定的某一时间水平下,确定公司信用质量从某一信用等级向另一信用等级转移的概率。

第二步:确定度量信用风险的期限,通常情况下为一年;第三步:确定每一信用等级的公司在给定的时间水平下的远期折现曲线,进而确定违约情况下贷款的价值,及确定相应的“回收率”;第四步:计算由信用等级迁移所引起的组合价值的远期分布。

举例:一笔5年期的固定贷款利率,利率为6%,贷款总额为100,目前信用等级为BBB 级。

则该笔贷款的市值为:44433322211)1(106)1(6)1(6166s r s r s r s r P ++++++++++++= 其中:i r 表示零息债券的无风险利率;i s 表示信用价差。

同时一年期的信用等级的迁移概率矩阵为:年末的等级迁移概率年初信用级别 AAA AA A BBB BB B CCC D AAA 98.01 8.330.68 0.06 0.12 0 0 0 AA 0.7 96.56 7.79 0.64 0.06 0.14 0.02 0 A 0.09 2.27 91.05 5.52 0.74 0.26 0.01 0.06 BBB 0.02 0.33 5.95 86.93 5.36 1.17 0.12 0.18 BB 0.03 0.14 0.67 7.73 80.53 8.84 1.00 1.06 B 0 0.11 0.24 0.43 6.48 83.46 4.07 5.2 CCC0.220.221.32.3811.2464.8619.79资料来源:Credit Metrics 技术文档,JP. .Morgan ,1997(穆迪公司的一年期的信用等级的迁移概率矩阵)假设债务人在于发放贷款的金融机构来说,这笔贷款在第一年结束时的市值是:66.108)0532.1(106)0493.1(6)0432.1(6)0372.1(66432=++++=P迁移到其它信用等级的情形,可以以此类推。

A.不同,但元素的存储顺序与逻辑顺序一致B.不同,且其元素的存储顺序可以与逻辑顺序不一致C.相同,元素的存储顺序与逻辑顺序一致D.相同,但其元素的存储顺序可以与逻辑顺序不一致正确答案:C解析:在线性表的顺序存储结构中,其存储空间连续,各个元素所占的字节数相同,在存储空间中是按逻辑顺序依次存放的。

知识模块:公共基础知识2.下列叙述中正确的是( )。

A.结点中具有两个指针域的链表一定是二叉链表B.结点中具有两个指针域的链表可以是线性结构,也可以是非线性结构C.循环链表是循环队列的链式存储结构D.循环链表是非线性结构正确答案:B解析:结点中具有两个指针域的链表既可以是双向链表也可以是二叉链表,双向链表是线性结构,二叉链表属于非线性结构。

循环链表是线性链表的一种形式,属于线性结构,采用链式存储结构,而循环队列是队列的一种顺序存储结构。

知识模块:公共基础知识3.在具有2n个结点的完全二叉树中,叶子结点个数为( )。

A.nB.n+1C.n-1D.n/2正确答案:A解析:由二叉树的定义可知,树中必定存在度为0的结点和度为2的结点,设度为0结点有a个,根据度为0的结点(即叶子结点)总比度为2的结点多一个,得度为2的结点有a-1个。

再根据完全二叉树的定义,度为1的结点有0个或1个,假设度1结点为0个,a+0+a-1=2n,得2a=2n-1,由于结点个数必须为整数,假设不成立;当度为1的结点为1个时,a+1+a-1=2n,得a=n,即叶子结点个数为n。

知识模块:公共基础知识4.下列算法中均以比较作为基本运算,则平均情况与最坏情况下的时间复杂度相同的是( )。

A.在顺序存储的线性表中寻找最大项B.在顺序存储的线性表中进行顺序查找C.在顺序存储的有序表中进行对分查找D.在链式存储的有序表中进行查找正确答案:A解析:寻找最大项,无论如何都要查看所有的数据,与数据原始排列顺序没有多大关系,无所谓最坏情况和最好情况,或者说平均情况与最坏情况下的时间复杂度是相同的。

FRM一级模考题(二)

FRM一级模考题(二)1. Based on a sample size of 100 and sample mean of $30, you estimate a 95%confidence interval for the mean weekly soft drink expenditures of students at alocal college. Your estimate of the confidence interval is $26.77 to $33.23. Sinceyou knew the standard deviation beforehand, your confidence interval was basedon a standard deviation closest to:A. 1.65.B. 6.59.C. 11.53.D. 16.48.Solution : DWith a known variance, the 95% confidence interval is constructed asSo you know that Solving for a provides 16.48.2. Consider a 1-year European call option with a strike price of $27.50 that iscurrently valued at $4.10 on a $25 stock. The 1-year risk-free rate is 6%. Whichof the following is closest to the value of the corresponding put option?A. $0.00B. $3.12.C. $5.00.D. $6.60.Solution : CUsing put-call parity: p = c + Xe-rT - So = 4.10 + 27.50e-0.06 - 25 = $5.00.3. A binomial interest-rate tree indicates a 1-year spot rate of 4%, and the price of the bond if rates decline is 95.25 and 93.75 if rates increase. The risk-neutral probability of an interest rate increase is 0.55. You hold a call option on the bond that expires in one year and has an exercise price of93.00. The option value is closest to:A. 1.17B. 0.97C. 1.44D. 1.37Solution : DThe call has payoff of 95.25 -93 = 2.25 if rates decline and payoffof 93.75- 93= 0.75 if rates increase. The expected discounted value of the payoffs is [0.55(0.75)+ 0.45(2.25)]/1.04 = 1.37.4. Cooper Industries is the pay-fixed counterparty in an interest rate swap. Theswap is based on a notional value of $2,000,000 and pays a floating rate basedon the 6-month Hong Kong Interbank Offered Rate (HIBOR). Cooper pays afixed rate of 7% semiannually. A swap payment has just been made. The swaphas a remaining life of 18 months, with pay dates at 6, 12, and 18 months. SpotHIBOR rates are shown in the table below.The value of the swap to Cooper Industries is closest to:A. $0.B. $6,346.C. $17,093.D. $72,486.Solution : CThe fixed payments made by Cooper are (0.07 / 2) x $2,000,000 = $70,000. Thepresent value of the fixed payments == $67,762 + $65,398 + $1,849,747 = $1,982,907The value of the floating rate payments received by Cooper at the payment date is thevalue of the notional principal, or $2,000,000.The value of the swap to Cooper Industries is ($2,000,000 - $1,982,907) =$17,093.5. A stack-and-roll hedge as described in the Metallgesellschaft case is bestdescribed as:A. buying futures contracts of different expirations and allowing them to expirein sequence.B. buying futures contracts of different expirations and closing out the positionshortly before expiration.C. using short-term futures to hedge a long-term risk exposure by replacingthem with longer-term contracts shortly before they expire.D. using short-term futures contracts with a larger notional value than thelong-term risk they are meant to hedge.Solution : CA stack is a bundle of futures contracts with the same expiration. Over time, a firmmay acquire stacks with various expiry dates. To hedge a long-term risk exposure, a firmwould close out each stack as it approaches expiry and enter into a contract with a moredistant delivery, known as a roll. This strategy is called a stack-and-roll hedge and isdesigned to hedge long-term risk exposures with short-term contracts. Using short-termfutures contracts with a larger notional value than the long-term risk they are meant tohedge could result in "over hedging" depending on the hedge ratio.。

谈谈FRM中的信用衍生品种类

谈谈FRM中的信用衍生品种类

谈谈FRM中的信用衍生品种类作者:高顿财经讲师JackDPCDerivative product company(DPC)是银行或其他低等级衍生品交易商的高质量的附属机构,可以使母机构与更高等级的衍射品交易商交易。

用 mirror trade 与母公司的账面相匹配,但是当破产时,资产会和母公司相分离。

CDS信用衍生品是与信用事件相关的。

可以说其标的就是信用事件(注意如何区分信用衍生品)。

一般的信用衍生品有:1、违约互换(CDS)。

CDS 的买方会向卖方定期的支付现金流,直到发生了信用事件(模拟题)违约互换更加像一个期权的性质。

所以:Payment in a credit swap is contingent upon a future credit event. Payment i n a total rate of return swap is not contingent upon a future credit event(就是说信用互换的支付总是视未来信用事件而定,而总收益互换却不是视未来信用事件而定,因为总收益互换的支付取决于参考利率和资产的贬值情况,是取决于市场变量的)。

银行利用与准备金等值的违约互换就可以完全解放资本。

2、first-to-default put为组合中第一个违约的资产保险,不管哪一个,payoff 就是 par 或者 book value。

3、总收益互换是将资产的收益换取固定的现金流,只要求出两个利率的差值再乘以面值即可。

4、以资产作抵押的 credit-link-note 是与贷款组合的表现相联系,当贷款贬值时,CLN 的购买者也需要承担一部分风险。

5、价差期权的支付:max(0,到期日的价差-执行价差)*面值*duration。

6、信用中介互换是在两个不愿直接交易的参与者之间加入一个高质量的第三方,当没有违约或者有利的一方违约的时候,中介机构就会获利。

CLN信用联系票据(CLN)是一种附息票据,是将信用风险证券化的结果。

Writing naked put optionsAnswer: CSelling an option is riskier than a spread or buying a put. In the case of selling a naked put option, the maximum loss equals the strike price. In the case of selling a naked call, the loss potential is unlimited, so it is the riskiest of the choices provided2 . A long position in a put option can be synthetically produced by:A. Long position in the underlying and a short position in a call.B. Short position in the underlying and a long position in a call.C. Long position in the underlying and a long position in a put.D. Short position in the underlying and a short position in a put.Answer: BA long put option has intrinsic value when the price of the underlying asset goes down. The payoff of a long put option is the same as the payoff of a short position in the underlying and a long position in the call. This synthetic alternative has value when the price of the under lying asset goes down . When the price of the underlying asset goes up, the call buyer will exercise and the call seller will need to liquidate the long position in the asset.3 . Consider a non-dividend paying stock currently priced at $37. It is known with certainty that over the next tw0 3-month periods, the price will either rise by 5% or fall by 5%. The continuously com pounded risk free rate is 7%. Calculate the value of a 6-month European call option with a strike price at $38.A. $1.065B. $1.234C. $1.856D. $2.710Answer: BThe binomial tree approach is shown as follows:4 . Consider a European call option on a non-dividend paying stock. T he current market price is $100, the strike price is $102, the time to maturity is 9 months and the risk free rate is 7.25%. Calculate the lower bound of the option price.A. $3.40B. $3.22C. $2.75D. $2.00Answer: A5 . Which of the following is most true about American options?A. Early exercise is never optimal.B. Early exercise of an American call. on a non-dividend paying stock is never optimal.C. Early exercise of an American put on a non-dividend paying stock is never optimal. 'D. Prior to exercise the value of the American call is always equal to the European call. Answer: BA stock's price drops following the payment of a dividend This reduces the value of a call. That'swhy it may make sense to exercise early if a stock pays a dividend。

FRM模型丨效用函数和风险偏好的辨析

FRM模型丨效用函数和风险偏好的辨析

FRM模型丨效用函数和风险偏好的辨析1.效用历史沿革效用的概念是丹尼尔·伯努利(不是数学家伯努利,但是他们都是伯努利家族的。

)在解释圣彼得堡悖论时提出的,目的是挑战以金额期望值作为决策的标准,证明期望收益并不是人们在做决策时的唯一衡量标准。

经济学家对于效用的理解是有一个过程的。

●19世纪的威廉姆·斯坦利·杰文斯、里昂·瓦尔拉斯和阿尔弗雷德·马歇尔等早期经济学家认为效用如同人们的身高和体重一样是可以测量的。

●而约翰·希克斯则尝试了只在序数性效用的假定下,也取得了很多的研究成果。

希克斯认为,效用的数值表现只是为了表达偏好的顺序,并非效用的数值。

因此,从分析消费者行为的方法来看,基数效用论者采用边际效用分析方法,序数效用论者采用无差异曲线分析方法。

从教科书等内容判断,现在比较通用的应该是后者的序数性效用。

1.1.效用概念的提出——圣彼得堡悖论圣彼得堡悖论是尼古拉·伯努利在1738年提出的一个概率期望值悖论。

它来自于一种掷币游戏,圣彼得堡游戏。

游戏规则为:掷出正面或者反面为成功,游戏者如果投掷成功,得奖金2元,游戏结束;若不成功,继续投掷,二次成功得奖金4元,游戏结束;这样,游戏者如果投掷不成功就反复继续投掷,直到成功,游戏结束。

如果n 次投掷成功,得奖金2n元,游戏结束。

首先,我们用公式1()k kk E X x p ∞==∑来计算这个游戏收益的数学期望值:23423411111()2222222222n n E X n n ==⨯+⨯+⨯+⨯++⨯= 从理论上来说,该游戏的期望值是无穷大的。

按照概率的理论,多次试验的结果将会接近于其数学期望。

这就出现了计算的期望值与实际情况的“矛盾”。

如果仅仅以期望值标准,我们将无法给这个游戏进行定价。

圣彼得堡悖论反映了决策理论和实际之间的差别。

人们总是不自觉地把模型与实际问题进行比较,但决策理论模型与实际问题并不是一个东西;圣彼得堡问题的理论模型是一个概率模型,它不仅是一种理论模型,而且本身就是一种统计的 “近似的”模型。

FRM一级模拟题
1 . Which of the following statements regarding the lease rate in commodity futures contracts is incorrect?
I The lease rate is the return required by the lender in exchange for lending a commodity.
II Assuming it is positive, as the lease rate increases, the futures price for a commodity increases.
III In a cash-and-carry arbitrage, the lease rate is earned whether or not the underlying commodity is actually loaned.
IV Lease rates are similar to dividends paid lo the lender of a share of common stock.
V If the lease rate is less than the risk-free rate, the forward market is said to be in contango.
A . II and III
B . III and V
C . I, III, and V
D . II and IV
Answer: A
The lease rate is the amount that a lender requires as compensation for Jending a commodity. In determining the price of a commodity futures contract, the lease rate, 81, is subtracted from the risk-free rate, r, as follows:
Assuming a positive lease rate, the lease rate effectively reduces the futures price, all else constant.
This also assumes that there is an active market for lending the commodity underlying the futures contract. The lease rate can only be earned by actually lending the underlying commodity.
2 . .Consider the factors that affect the price of futures contracts on various commodities. Which of the following statements does not accurately describe the relationship between a commodity's futures price and its underlying factors?
A. Gold futures have an implicit lease rate which, because it is not actually paid by commodity borrowers, creates incentive to' hold physical rather than synthetic gold as ideal strategy to gain gold exposure.
B. Natural gas is produced relatively consistently but has seasonal demand, causing the futures price to rise steadily in the fall months, since natural gas is too expensive to store.
C. The cost of storing corn, which has relatively constant demand, causes the futures price to rise until the next harvest at which point the price falls.
D. Relatively constant worldwide demand for oil and its ability to be cheaply transported keep oil prices relatively stable in the absence of short-run supply and demand.
Answer: A
Gold futures have an implicit lease rate, because it is not actually paid by commodity borrowers, which creates incentive to hold physical rather than synthetic gold as ideal strategy to gain gold exposure.
Gold can be loaned out to financial intermediaries and other investors willing to pay the lease rate (the price for borrowing the gold) to the lender. Thus, holding physical gold requires the investor to forgo earning the lease rate while also incurring storage costs. Therefore, the ideal gold exposure strategy is generally to hold synthetic gold.
3 . The S&P 500 index is trading at l,025. The S&P 500 pays an expected dividend yield of l .2% and the current risk-free rate is 2.75%. The value of a 3-month futures contract on the S&P 500 index is closest to:
A. $1,028.98
B. $1,108.59
C. $984.86
D. $1,025.00
Answer: A
4 . Which of the following statements describing the role of a convenience yield in pricing commodity futures is true? The convenience yield:
I will cause contango in the futures pricing relationship.
II Effectively reduces the cost of carry in the futures pricing relationship.
III Eliminates the potential for arbitrage between the futures and spot price.
IV Accounts for additional costs for storing an asset in the futures pricing Relationship.
A. I only
B. II only
C. II, III, an d IV only
D. I and II only
Answer: B
The convenience yield suggests there is a benefit, or convenience, to owning the spot asset. This generally means the spot price of the underlying asset will be above the futures price (normal backwardation). The convenience yield serves to reduce the cost of carry in the futures pricing relationship. .
5 . Consider a 6-month futures contract on the S&P 500, and suppose the current value of the index is1330. Suppose the dividend yield is l.5% annually for the stocks underlying the index, and that the continuously compounded risk-free interest rate is 5.5% annually. What is the cost of carry for this futures contract?
A. 4.0%
B. -4.0%
C. 2.0%
D. -2.0%。
