案例LTCM

案例LTCMLTCM案例分析。

LTCM(Long-Term Capital Management)是一家成立于1994年的对冲基金公司,由约翰·默顿、罗伯特·默顿和戴维·薛弗等人创立。

该公司曾一度在金融市场上表现出色,但最终却因为投资失误导致了一场金融危机,成为了金融史上的经典案例。

LTCM的投资策略主要是利用套利交易获取收益,他们通过利用不同市场之间的价格差异进行交易,从而获得稳定的收益。

然而,随着金融市场的变化和不确定性的增加,LTCM的投资策略也暴露出了一些问题。

首先,LTCM的杠杆比例过高。

他们利用高杠杆来放大投资收益,但也增加了投资的风险。

当市场出现剧烈波动时,高杠杆会使得损失倍增,最终导致了LTCM的破产。

其次,LTCM的投资组合缺乏多样性。

他们主要集中在利率套利和债券套利上,而忽视了其他投资领域的机会。

当市场出现大幅波动时,他们的投资组合无法有效分散风险,导致损失加剧。

此外,LTCM的风险管理和监控机制也存在问题。

他们过于依赖数学模型和计算机算法来进行风险管理,而忽视了市场的不确定性和人为因素。

当市场出现超出模型预期的情况时,他们无法及时做出调整,最终导致了灾难性的后果。

最后,LTCM的高管团队缺乏有效的应对危机能力。

他们过于自信和乐观,没有及时意识到市场的变化和风险的增加,导致了最终的失败。

总的来说,LTCM案例是一个典型的投资失误案例,他们的失败主要是由于高杠杆、缺乏多样性、风险管理不足和高管团队失误等多方面原因造成的。

这个案例给我们提供了一个宝贵的教训,即在投资过程中,要注意控制杠杆,多样化投资组合,加强风险管理和监控,以及建立有效的危机应对机制,避免重蹈LTCM的覆辙。

在金融投资领域,LTCM案例也被广泛用来教育投资者和金融从业人员,帮助他们认识到投资中的风险和不确定性,以及重视风险管理和监控的重要性。

同时,LTCM案例也提醒我们,金融市场的变化无常,投资者需要保持谨慎和理性,避免盲目跟风和投机行为,以免陷入类似的困境。

1988年9月23日,LTCM 濒临破产,一个由各大金融机构临时组成的财团接管了该公司的业务。

当人们从金融报刊中得知这一消息时,无不感到震惊不已。

这次LTCM危机的爆发以及纽约联邦储备银行对接管行动的组织都显示了这样一个事实:不受管制的非银行性金融机构可能会使整个国际金融体系变得更加脆弱,甚至有崩溃的危险。

长期资本管理公司的业务主要针对那些由于流动性或风险特征不同而在收益上稍有差异的相似证券。

在一个典型的交易中,LTCM通过承诺支付新发行的30年期美国财政债券来获得资金,然后用这笔钱来购买以前发行的30年期财政债券,这些前期债券的市场比新发行的债券小,出售相对较困难(流动性较性),因此必须提供稍高的回报率。

美国长期资本管理基金巨额亏损案例分析

美国长期资本管理基金巨额亏损案例分析【案例介绍】总部设在离纽约市不远的格林威治的美国长期资本管理公司(LTCM),是一家主要从事定息债务工具套利活动的对冲基金。

该基金创立于1994年,主要活跃于国际债券和外汇市场,利用私人客户的巨额投资和金融机构的大量贷款,专门从事金融市场炒作,与量子基金、老虎基金、欧米伽基金一起称为国际四大“对冲基金”。

LTCM掌门人梅里韦瑟(John Meniwehter),这位被誉为能“点石成金”的华尔街债券套利之父,聚集了华尔街一批证券交易的精英加盟:1997年诺贝尔经济学奖获得者默顿(Robery merton)和舒尔芡(Myron Scholes),前财政部副部长及联储副主席莫里斯(David Mullins),前所罗门兄弟债券交易部主管罗森菲尔德(Rosenfeld),以至于有人称之为“梦幻组合”。

在1994—1997年间,它的业绩辉煌而诱人,以成立初期的12.5亿美元资产净值迅速上升到1997年12月的48亿美元,每年的投资回报为28.5%、42.8%、40.8%和17%,1997年更是以1994年投资1美元派2.82美元红利的高回报率让LTCM身价倍增。

然而,在1998年全球金融动荡中,长期资本管理公司难逃一劫,从5月俄罗斯金融风暴到9月全面溃败,短短的150多天资产净值下降90%,出现43亿美元巨额亏损,仅余5亿美元,已走向破产边缘。

9月23日,美联储出面组织安排,以Merrill Lynch、JP Morgan为首的15家国际性金融机构注资37.25亿美元购买了LTCM90%的股权,共同接管了LTCM,从而避免了它倒闭的厄运。

那么,“对冲基金”到底为何物?其具体操作又是怎样进行的呢?对冲基金的英文名称为Hedge Fund,意为“风险对冲过的基金”,起源于50年代初的美国。

其操作的宗旨,在于利用期货、期权等金融衍生产品以及对相关联的不同股票进行空买空卖、风险对冲的操作技巧,在一定程度上可规避和化解证券投资风险。

利率互换的基差交易策略

利率互换的基差交易策略

==================================================================利率互换的基差交易策略从长期资本管理公司神话破灭看:长期资本管理公司(LTCM):一家仅仅存活5年的基金管理公司,却是迄今为止最有影响的套利基金;一度是华尔街备受推崇的明星,最终却引发了华尔街历史上的一场灾难;一群曾将不确定的世界视为冷血赌局的投机天才,最终却输得一败涂地;一个有史以来最生动的资本市场案例,足以让投资者、基金管理人和监管当局沉思。

利率互换(Interest Rate Swap,IRS)是指交易双方约定在未来的一定期限内,对约定的名义本金按照不同的计息方法定期交换利息的一种场外交易的金融合约。

一般来说,利率互换合约交换的只是不同特征的利息,而不涉及实质本金的互换,所以将其本金称为名义本金。

在大多数利率互换中,其中一方支付的利息是基于浮动利率,而另一方的支付是基于固定利率或浮动利率,浮动利率对固定利率的互换是标准型的利率互换,也是最为普遍的利率互换。

利率互换的基差交易策略一般情况下,利率互换的走势从方向上来说,基本和债券一致。

互换和债券组合策略是目前各种套利策略中最常见的一种。

这种套利并不是做多或做空某个债券,而是做多或做空互换与债券之间的利差。

一般情况下利率互换走势应与相应期限的无风险债券走势基本一致,互换与现券利差应保持稳定。

我们可以将以FR007为基准的5年期人民币IRS利率走势和5年期政策性金融债走势比较来看,具体如下图所示:5年期人民币IRS利率走势和5年期政策性金融债走势比较从上图中我们可以发现几点:其一,5年期人民币IRS利率走势和5年期政策性金融债走势基本一致,长期来看,5年利率互换和5年金融债的利差均值接近于0。

虽说IRS的利率反映的是未来5年远期利率的预期折现到现在的现值,但是市场对未来利率的预期多基于当前的市场状况,所以IRS利率走势基本和5年期现券基本一致。

LTCM给我们的教训

LTCM的失败总结及启示长期资本管理公司(LTCM)是总部设立在康涅狄格州格林威治的一家主要从事定息债务工具套利活动的合伙制私人投资管理公司。

由所罗门兄弟的前副董事长暨债券交易部主管约翰.梅韦瑟于1994年成立,董事会成员包括了因制定选择权定价公式,而在1997年共同获得诺贝尔经济学奖的麦伦·休斯和罗伯特·C·默顿。

LTCM在开始的时候获得了28~59%的年度收益率以及4年总计185%的投资回报率的巨大成就。

然而在1998年俄罗斯金融危机后,却在不到四个月的时间里造成了46亿美元的巨大亏损,不得不请求美国联准会的财政介入。

不久之后,该基金在2000年初倒闭。

长期资本管理公司虽然只存在了短短的5年,但是它却是迄今为止最有影响的套利基金,并引发了华尔街历史上的一场灾难。

LTCM虽然拥有两位学术大师、一位前联储副主席以及一群华尔街最能赚钱的对冲套利高手,但是却依旧如流星般转瞬即逝。

LTCM的倒闭并不是突然的,而是由其自身所存在问题的长期积累的结果。

在我看来,LTCM失败的最主要的因素便是他们建立的数学模型。

第一,他们的模型太理想化,而他们忽略却了一个事实,那就是其他交易员并不是完全理性的。

他们相信别人都像他们自己的交易员一样,能够毫无感情地参与交易。

LCTM忘记了在一个他们眼里极其愚蠢的市场上一定要时刻保持充足的流动性,因为他们的模型认为需要用上这种流动性的事百年不遇。

结果是,97年底和98年初,这种事情连续地发生在了他们身上。

简单来说,“百年不遇”的事情两年之内就发生了两次。

事实上,类似的事件92年就曾发生过,而长期资本管理公司的模型根本就没有追溯到“那么久”。

第二,冲基金的运作模式,就是从正反两个角度下注投资,无论是市场是升是跌,我们手中的基金至少有一部分是盈利的,保证我们的投资不会全线亏损。

长期资本管理公司从1994年到1996年都是根据独特的数学模型发掘良好的债券投机机遇,并对债券投资进行对冲。

案例十六1998年长期资本管理公司事件

案例十六:1998年长期资本管理公司事件美国长期资本管理公司(Long-Term Capital Management,简称LTCM)成立于1994年2月,总部设在离纽约市不远的格林威治,是一家主要从事定息债务工具套利活动的对冲基金。

自创立以来,LTMC一直保持骄人的业绩,公司的交易策略是"市场中性套利"即买入被低估的有价证券,卖出被高估的有价证券。

LTMC将金融市场的历史资料、相关理论学术报告及研究资料和市场信息有机的结合在一起,通过计算机进行大量数据的处理,形成一套较为完整的电脑数学自动投资系统模型,建立起庞大的债券及衍生产品的投资组合,进行投资套利活动,LTMC凭借这个优势,在市场上一路高歌。

1996年,LTMC大量持有意大利、丹麦、希腊政府债券,而沽空德国债券,LTMC模型预测,随着欧元的启动上述国家的债券与德国债券的息差将缩减,市场表现与LTMC的预测惊人的一致,LTMC获得巨大收益。

LTMC的数学模型,由于建立在历史数据的基础上,在数据的统计过程中,一些概率很小的事件常常被忽略掉,因此埋下了隐患:一旦这个小概率事件发生,其投资系统将产生难以预料的后果。

所谓Black-Scholes-Merton公式仍以正态分布为基础(这是因为该公式涉及Wiener过程,而Wiener过程的定义涉及正态分布),故“长期资本”的风险投资策略仍以“线性”和“连续”的资产价格模型为出发点。

具体来说,该对冲基金的核心策略是“收敛交易”。

此策略并不关心某一股票或债券的价格是升还是降,而是赌在相关股票或债券的价格向“常态”收敛上。

“长期资本”的一项赌注下在美国30年国库卷和29年国库卷的价格收敛上(卖空前者,买入后者),本以为可以不论价格升降都稳操胜券。

不料,亚洲和俄国的金融危机使惊恐的投资者一窝蜂地涌向似更安全吉祥的30年国库卷,结果造成30年国库卷和29年国库卷的价格发散,而非收敛。

类似的其它几个"收敛交易"也都以发散而告终。

梅里韦瑟
LTCM的灵魂人物是梅里韦瑟(John Meriwether)。他是芝加哥大学的MBA,后来加盟所罗 门兄弟公司,在20世纪70年代,就已经是债券市场上叱咤风云的人物。20世纪60年代中期之前,债 券市场上的交易单调而范围:汇率是固定的,利率受到管制,金价一成不变。但20世纪60年代之后, 债券市场逐渐变得更加刺激。持续不断的通货膨胀、突然爆发的中东石油危机打破了过去墨守的常规 。各国纷纷放松对利率和汇率的管制。各种新型的债券和交易工具层出不穷。刚刚问世的计算机很快 被应用到债券投资中。
如果不是发生了一件意外的事情,梅里韦瑟可能会一直留在所罗门兄弟公司,直到有一天执掌大 权。但是,1992年,一位34岁的交易员Paul Mozer在美国国债交易中有欺诈行为。做为他的主管 上司,梅里韦瑟被迫引咎辞职。尽管后来事情逐渐平息,但梅里韦瑟在所罗门兄弟公司的升迁之路彻 底被堵死了。这一年,他已经45岁了。怎么办?思来想去,梅里韦瑟终于决定,干脆把队伍拉出来, 自己成立一个对冲基金,自己创业。这就是LTCM的由来。

LESSONS FROM THE COLLAPSE OF HEDGE FUND, LONG-TERM CAPITAL MANAGEMENTBy David ShirreffBarings, the Russian meltdown, Metallgesellschaft, Procter & Gamble, LTCM. These are all events in the financial markets which have become marker buoys to show us where we went wrong, in the hope that we won't allow quite the same thing to happen again. The common weakness, in these cases, was the misguided assumption that ‘our counterparty and the market it was operating in, were performing within manageable limits.’ But once those limits were crossed for whatever reason, disaster was difficult to head off.The LTCM fiasco is full of lessons about:1. Model risk2. Unexpected correlation or the breakdown of historical correlations3. The need for stress-testing4. The value of disclosure and transparency5. The danger of over-generous extension of trading credit6. The woes of investing in star quality7. And investing too little in game theory.The latter because LTCM's partners were playing a game up to hilt.John Meriwether, who founded Long-Term Capital Partners in 1993, had been head of fixed income trading at Salomon Brothers. Even when forced to leave Salomon in 1991, in the wake of the firm's treasury auction rigging scandal (another marker buoy), Meriwether continued to command huge loyalty from a team of highly cerebral relative-value fixed income traders, and considerable respect from the street. Teamed up with a handful of these traders, two Nobel laureates, Robert Merton and Myron Scholes, and former regulator David Mullins, Meriwether and LTCM had more credibility than the average broker/dealer on Wall Street.It was a game, in that LTCM was unregulated, free to operate in any market, without capital charges and only light reporting requirements to the US Securities & Exchange Commission (SEC). It traded on its good name with many respectable counterparties as if it was a member of the same club. That meant an ability to put on interest rate swaps at the market rate for no initial margin - an essential part of its strategy. It meant being able to borrow 100% of the value of any top-grade collateral, and with that cash to buy more securities and post them as collateral for further borrowing: in theory it could leverage itself to infinity. In LTCM's first two full years of operation it produced 43% and 41% return on equity and had amassed an investment capital of $7 billion.Meriwether was renowned as a relative-value trader. Relative value means (in theory) taking little outright market risk, since a long position in one instrument is offset by a short position in a similar instrument or its derivative. It means betting on small price differences which are likely to converge over time as the arbitrage is spotted by the rest of the market and eroded. Trades typical of early LTCM were, for example, to buy Italian government bonds and sell German Bund futures; to buy theoretically underpriced off-the-run US treasury bonds (because they are less liquid) and go short on-the-run (more liquid) treasuries. It played the same arbitrage in theinterest-rate swap market, betting that the spread between swap rates and the most liquid treasury bonds would narrow. It played long-dated callable Bunds against Dm swaptions. It was one of the biggest players on the world's futures exchanges, not only in debt but also equity products.To make 40% return on capital, however, leverage had to be applied. In theory, market risk isn't increased by stepping up volume, provided you stick to liquid instruments and don't get so big that you yourself become the market.Some of the big macro hedge funds had encountered this problem and reduced their size by giving money back to their investors. When, in the last quarter of 1997 LTCM returned $2.7 billion to investors, it was assumed to be for the same reason: a prudent reduction in its positions relative to the market.But it seems the positions weren't reduced relative to the capital reduction, so the leverage increased. Moreover, other risks had been added to the equation. LTCM played the credit spread between mortgage-backed securities (including Danish mortgages) or double-A corporate bonds and the government bond markets. Then it ventured into equity trades. It sold equity index options, taking big premium in 1997. It took speculative positions in takeover stocks, according to press reports. One such was Tellabs whose share price fell over 40% when it failed to take over Ciena, says one account. A filing with the SEC for June 30 1998 showed that LTCM had equity stakes in 77 companies, worth $541 million. It also got into emerging markets, including Russia. One report said Russia was "8% of its book" which would come to $10 billion!Some of LTCM's biggest competitors, the investment banks, had been clamouring to buy into the fund. Meriwether applied a formula which brought in new investment, as well as providing him and his partners with a virtual put option on the performance of the fund. During 1997, under this formula [see separate section below, titled UBS Fiasco], UBS put in $800 million in the form of a loan and $266 million in straight equity. Credit Suisse Financial Products put in a $100 million loan and $33 million in equity. Other loans may have been secured in this way, but they haven't been made public. Investors in LTCM were pledged to keep in their money for at least two years.LTCM entered 1998 with its capital reduced to $4.8 billion.A New York Sunday Times article says the big trouble for LTCM started on July 17 when Salomon Smith Barney announced it was liquidating its dollar interest arbitrage positions: "For the rest of the that month, the fund dropped about 10% because Salomon Brothers was selling all the things that Long-Term owned." [The article was written by Michael Lewis, former Salomon bond trader and author ofLiar's Poker. Lewis visited his former colleagues at LTCM after the crisis and describes some of the trades on the firm's books]On August 17,1998 Russia declared a moratorium on its rouble debt and domestic dollar debt. Hot money, already jittery because of the Asian crisis, fled into high quality instruments. Top preference was for the most liquid US and G-10 government bonds. Spreads widened even between on- and off-the-run US treasuries.Most of LTCM's bets had been variations on the same theme, convergence between liquid treasuries and more complex instruments that commanded a credit or liquidity premium. Unfortunately convergence turned into dramatic divergence. LTCM's counterparties, marking their LTCM exposure to market at least once a day, began to call for more collateral to cover the divergence. On one single day, August 21, the LTCM portfolio lost $550 million, writes Lewis. Meriwether and his team, still convinced of the logic behind their trades, believed all they needed was more capital to see them through a distorted market.Perhaps they were right. But several factors were against LTCM.1. Who could predict the time-frame within which rates would converge again?2. Counterparties had lost confidence in themselves and LTCM.3. Many counterparties had put on the same convergence trades, some of them as disciples of LTCM.4. Some counterparties saw an opportunity to trade against LTCM's known or imagined positions.In these circumstances, leverage is not welcome. LTCM was being forced to liquidate to meet margin calls.On September 2, 1998 Meriwether sent a letter to his investors saying that the fund had lost $2.5 billion or 52% of its value that year, $2.1 billion in August alone. Its capital base had shrunk to $2.3 billion. Meriwether was looking for fresh investment of around $1.5 billion to carry the fund through. He approached those known to have such investible capital, including George Soros, Julian Robertson and Warren Buffett, chairman of Berkshire Hathaway and previously an investor in Salomon Brothers [LTCM incidentally had a $14 million equity stake in Berkshire Hathaway], and Jon Corzine, then co-chairman and co-chief executive officer at Goldman Sachs, an erstwhile classmate at the University of Chicago. Goldman and JP Morgan were also asked to scour the market for capital.But offers of new capital weren't forthcoming. Perhaps these big players were waiting for the price of an equity stake in LTCM to fall further. Or they were making money just trading against LTCM's positions. Under these circumstances, if true, it was difficult and dangerous for LTCM to show potential buyers more details of its portfolio. Two Merrill executives visited LTCM headquarters on September 9,1998for a "due diligence meeting", according to a later Financial Times report (on October 30, 1998). They were provided with "general information about the fund's portfolio, its strategies, the losses to date and the intention to reduce risk". But LTCM didn't disclose its trading positions, books or documents of any kind, Merrill is quoted as saying.The US Federal Reserve system, particularly the New York Fed which is closest to Wall Street, began to hear concerns about LTCM from its constituent banks. In the third week of September, Bear Stearns, which was LTCM's clearing agent, said it wanted another $500 million in collateral to continue clearing LTCM's trades. On Friday September 18, 1998, New York Fed chairman Bill McDonough made "a series of calls to senior Wall Street officials to discuss overall market conditions", he told the House Committee on Banking and Financial Services on October 1. "Everyone Ispoke to that day volunteered concern about the serious effect the deteriorating situation of Long-Term could have on world markets."Peter Fisher, executive vice president at the NY Fed, decided to take a look at the LTCM portfolio. On Sunday September 20, 1998, he and two Fed colleagues, assistant treasury secretary Gary Gensler, and bankers from Goldman and JP Morgan, visited LTCM's offices at Greenwich, Connecticut. They were all surprised by what they saw. It was clear that, although LTCM's major counterparties had closely monitored their bilateral positions, they had no inkling of LTCM's total off balance sheet leverage. LTCM had done swap upon swap with 36 different counterparties. In many cases it had put on a new swap to reverse a position rather than unwind the first swap, which would have required a mark-to-market cash payment in one direction or the other. LTCM's on balance sheet assets totalled around $125 billion, on a capital base of $4 billion, a leverage of about 30 times. But that leverage was increased tenfold by LTCM's off balance sheet business whose notional principal ran to around $1 trillion.The off balance sheet contracts were mostly nettable under bilateral Isda (International Swaps & Derivatives Association) master agreements. Most of them were also collateralized. Unfortunately the value of the collateral had taken a dive since August 17.Surely LTCM, with two of the original masters of derivatives and option valuation among its partners, would have put its portfolio through stress tests to match recent market turmoil. But, like many other value-at-risk (Var) modellers on the street, their worst-case scenarios had been outplayed by the horribly correlated behaviour of the market since August 17. Such a flight to quality hadn't been predicted, probably because it was so clearly irrational.According to LTCM managers their stress tests had involved looking at the 12 biggest deals with each of their top 20 counterparties. That produced a worst-case loss of around $3 billion. But on that Sunday evening it seemed the mark-to-market loss, just on those 240-or-so deals, might reach $5 billion. And that was ignoring all the other trades, some of them in highly speculative and illiquid instruments.The next day, Monday September 21, 1998, bankers from Merrill, Goldman and JP Morgan continued to review the problem. It was still hoped that a single buyer for the portfolio could be found - the cleanest solution.According to Lewis's article LTCM's portfolio had its second biggest loss that day, of $500 million. Half of that, says Lewis, was lost on a short position in five-year equity options. Lewis records brokers' opinion that AIG had intervened in thin markets to drive up the option price to profit from LTCM's weakness. At that time, as was learned later, AIG was part of a consortium negotiating to buy LTCM's portfolio. By this time LTCM's capital base had dwindled to a mere $600 million. That evening, UBS, with its particular exposure on a $800 million credit, with $266 million invested as a hedge, sent a team to Greenwich to study the portfolio.The Fed’s Peter Fischer invited those three banks and UBS to breakfast at the Fed headquarters in Liberty Street the following day. The bankers decided to form working groups to study possible market solutions to the problem, given the absenceof a single buyer. Proposals included buying LTCM's fixed income positions, and "lifting" the equity positions (which were a mixture of index spread trades and total return swaps, and the takeover bets). During the day a third option emerged as the most promising: seeking recapitalization of the portfolio by a consortium of creditors. But any action had to be taken swiftly. The danger was a single default by LTCM would trigger cross-default clauses in its Isda master agreements precipitating a mass close-out in the over-the-counter derivatives markets. Banks terminating their positions with LTCM would have to rebalance any hedge they might have on the other side. The market would quickly get wind of their need to rebalance and move against them. Mark-to-market values would descend in a vicious spiral. In the case of the French equity index, the CAC 40, LTCM had apparently sold short up to 30% of the volatility of the entire underlying market. The Banque de France was worried that a rapid close-out would severely hit French equities. There was a wider concern that an unknown number of market players had convergence positions similar or identical to those of LTCM. In such a one-way market there could be a panic rush for the door.A meltdown of developed markets on top of the panic in emerging markets seemed a real possibility. LTCM's clearing agent Bear Stearns was threatening to foreclose the next day if it didn't see $500 million more collateral. Until now, LTCM had resisted the temptation to draw on a $900 million standby facility that had been syndicated by Chase Manhattan Bank, because it knew that the action would panic its counterparties. But the situation was now desperate. LTCM asked Chase for $500 million. It received only $470 million since two syndicate members refused to chip in. To take the consortium plan further, the biggest banks, either big creditors to LTCM, or big players in the over-the-counter markets, were asked to a meeting at the Fed that evening. The plan was to get 16 of them to chip in $250 million each to recapitalize LTCM at $4 billion.The four core banks met at 7pm and reviewed a term sheet which had been drafted by Merrill Lynch. Then at 8.30 bankers from nine more institutions showed. They represented: Bankers Trust, Barclays, Bear Stearns, Chase, Credit Suisse First Boston, Deutsche Bank, Lehman Brothers, Morgan Stanley, Credit Agricole, Banque Paribas, Salomon Smith Barney, Societe Generale. David Pflug, head of global credit risk at Chase warned that nothing would be gained a) by raking over the mistakes that had got them in this room, and b) by arguing about who had the biggest exposure: they were all in this equally and together.The delicate question was how to preserve value in the LTCM portfolio, given that banks around the room would be equity investors, and yet, at the same time, they would be seeking to liquidate their own positions with LTCM to maximum advantage. It was clear that John Meriwether and his partners would have to be involved in keeping such a complex portfolio a going concern. But what incentive would they have if they no longer had an interest in the profits? Chase insisted that any bailout would first have to return the $470 million drawn down on the syndicated standby facility. But nothing could be finalized that night since few of the representatives present could pledge $250 million or more of their firm's money.The meeting resumed at 9.30 the next morning. Goldman Sachs had a surprise: its client, Warren Buffett, was offering to buy the LTCM portfolio for $250 million, and recapitalize it with $3 billion from his Berkshire Hathaway group, $700 million from AIG and $300 million from Goldman. There would be no management role forMeriwether and his team. None of LTCM's existing liabilities would be picked up, yet all current financing had to stay in place. Meriwether had until 12.30 to decide.By 1pm it was clear that Meriwether had rejected the offer, either because he didn't like it, or, according to his lawyers, because he couldn't do so without consulting his investors, which would have taken him over the deadline.The bankers were somewhat flabbergasted by Goldman's dual role. Despite frequent requests for information about other possible bidders, Goldman had dropped no hint at previous meetings that there was something in the pipeline. Now the banks were back to the consortium solution. Since there were only 13 banks, not 16, they'd have to put in more than $250 million each. Bear Stearns offered nothing, feeling that it had enough risk as LTCM's clearing agent. [Their special relationship may have been the source of some acrimony: LTCM had an $18 million equity stake in Bear Stearns, matched by investments in LTCM of $10 million each by Bear Stearns principals James Cayne and Warren Spector]. Lehman Brothers also declined to participate . In the end 11 banks put in $300 million each, Societe Generale $125 million, and Credit Agricole and Paribas $100 million each, reaching a total fresh equity of $3.625 billion. Meriwether and his team would retain a stake of 10% in the company. They would run the portfolio under the scrutiny of an oversight committee representing the new shareholding consortium.The message to the market was that there would be no fire-sale of assets. The LTCM portfolio would be managed as a going concern.In the first two weeks after the bail-out, LTCM continued to lose value, particularly on its dollar/yen trades, according to press reports which put the loss at $200 million to $300 million. There were more attempts to sell the portfolio to a single buyer. According to press reports the new LTCM shareholders had further talks with Buffett, and with Saudi prince Alwaleed bin talal bin Abdelaziz. But there was no sale. By mid-December, 1998 the fund was reporting a profit of $400 million, net of fees to LTCM partners and staff.In early February, 1999 there were press reports of divisions between banks in the bailout consortium, some wishing to get their money out by the end of the year, others happy to "stay for the ride" of at least three years. There was also a dispute about how much Chase was charging for a funding facility to LTCM. Within six months there were reports that Meriwether and some of his team wanted to buy out the banks, with a little help from their friend Jon Corzine, who was due to leave Goldman Sachs after its flotation in May, 1999.By June 30, 1999 the fund was up 14.1%, net of fees, from last September. Meriwether's plan approved by the consortium, was apparently to redeem the fund, now valued at around $4.7 billion, and to start another fund concentrating on buyouts and mortgages. On July 6, 1999, LTCM repaid $300 million to its original investors who had a residual stake in the fund of around 9%. It also paid out $1 billion to the 14 consortium members. It seemed Meriwether was bouncing back.Post mortemThe LTCM fiasco naturally inspired a hunt for scapegoats:1. First in line were Meriwether and his crew of market professors.2. Second were the banks which conspired to give LTCM far more credit, in aggregate, than they'd give a medium-size developing country. Particularly distasteful was the combination of credit exposure by the institutions themselves, and personal investment exposure by the individuals who ran them.Merrill Lynch protested that a $22 million investment on behalf of its employees was not sinister. LTCM was one of four investment vehicles which employees could opt to have their deferred payments invested in. Nevertheless, that rather cosy relationship may have made it more difficult for credit officers to ask tough questions of LTCM. There were accusations of "croney capitalism" as Wall Street firms undertook to bail out, with shareholders' money, a firm in which their officers had invested, or were thought to have invested, part of their personal wealth.3. Third in line was the US Federal Reserve system. Although no public money was spent - apart from hosting the odd breakfast - there was the implication that the Fed was standing behind the banks, ready to provide liquidity until the markets became less jittery and more rational. Wouldn't this simply encourage other hedge funds and lenders to hedge funds to be as reckless in future?4. Fourth culprit was poor information. Scant disclosure of its activities and exposures, by LTCM, as with many hedge funds, was a major factor in allowing it to put on such leverage. There was also no mechanism whereby counterparties could learn how far LTCM was exposed to other counterparties.5. Fifth was sloppy market practice, such as allowing a non-bank counterparty to write swaps and pledge collateral for no initial margin as if it were part of a peer-group top-tier banks.1.LTCM's risk management.Despite the presence of Nobel laureates closely identified with option theory it seems LTCM relied too much on theoretical market-risk models and not enough on stress-testing, gap risk and liquidity risk. There was an assumption that the portfolio was sufficiently diversified across world markets to produce low correlation. But in most markets LTCM was replicating basically the same credit spread trade. In August and September 1998 credit spreads widened in practically every market at the same time.LTCM risk managers kidded themselves that the resultant net position of LTCM's derivatives transactions bore no relations to the billions of dollars of notional underlying instruments. Each of those instruments and its derivative has a market price which can shift independently, each is subject to liquidity risk.LTCM sources apparently complain that the market started trading against its known positions. That seems like special pleading. Meriwether et al must have been in the markets long enough to know they are merciless, and to have been just as merciless themselves. "All they that take the sword shall perish with the sword." [Matthew, xxvi, 52]2. Risk management by LTCM counterpartiesPractically the whole street had a blind spot when it came to LTCM. They forgot the useful discipline of charging non-bank counterparties initial margin onswap and repo transactions. Collectively they were responsible for allowing LTCM to build up layer upon layer of swap and repo positions.They believed that the first-class collateral they held was sufficient to mitigate their loss if LTCM disappeared. It may have been over time, but their margin calls to top up deteriorating positions simply pushed LTCM further towards the brink.Their credit assessment of LTCM didn't include a global view of its leverage and its relationship with other counterparties.A working group on highly leveraged institutions set up by the Basle Committee on Banking Supervision reported its findings in January, 1999 drawing many lessons from the LTCM case. It criticized the banks for building up such exposures to such an opaque institution. They had placed a "heavy reliance on collateralization of direct mark-to-market exposures" the report said. "This in turn made it possible for banks to compromise other critical elements of effective credit risk management, including upfront due diligence, exposure measurement methodologies, the limit setting process, and ongoing monitoring of counterparty exposure, especially concentrations and leverage."The working group also noted that banks' "covenants with LTCM did not require the posting of, or increase in, initial margin as the risk profile of the counterparty changed, for instance as leverage increased". (For full reports, see “Sound Practices for Banks’ Interactions with Highly Leveraged Institutions,” and “Banks’ Interactions with Highly Leveraged Institutions”.) Another report in June, 1999 by the Counterparty Risk Management Policy Group, a group of 12 leading investment banks, suggested many ways in which information-sharing and transparency could be improved. It noted the importance of measuring liquidity risk, and improving market conventions and market practices, such as charging initial margin.3. SupervisionSupervisors themselves showed a certain blinkered view when it came to banks' and securities firms' relationships with hedge funds, and a huge fund like LTCM in particular. The US Securities & Exchange Commission (SEC) appears to assess the risk run by individual broker dealers, without having enough regard for what is happening in the sector as a whole, or in the firms' unregulated subsidiaries. In testimony to the House Committee on Banking and Financial Services on October 1, 1998, Richard Lindsey, director of the SEC's market regulation division recalled the following: "When the commission learned of LTCM's financial difficulties in August, the commission staff and the New York Stock Exchange surveyed major broker-dealers known to have credit exposure to one or more large hedge funds. The results of our initial survey indicated that no individual broker-dealer had exposure to LTCM that jeopardized its required regulatory capital or its financial stability."As the situation at LTCM continued to deteriorate, we learned that although significant amounts of credit were extended to LTCM by US securities firms, this lending was on a secured basis, with collateral collected and marked-to-the-market daily. Thus, broker-dealers' lending to LTCM was done in a manner that was consistent with the firms' normal lending activity. The collateral collected from LTCM consisted primarily of highly liquid asseets, such as US treasury securities or G-7 country sovereign debt. Any shortfalls in collateral were met by margin calls toLTCM. As of the date of the rescue plan, it appears that LTCM had met all of its margin calls by US securities firms. Moreover, our review of the risk assessment information submitted to the commission suggests that any exposure to LTCM existed outside the US broker-dealer, either in the holding company or its unregistered affiliates."The sad truth revealed by this testimony is that the SEC and the NYSE were concerned only with the risk ratios of their registered firms and were ignorant and unconcerned, as were the firms themselves, about the market's aggregate exposure to LTCM.Bank of England experts note the absence of any covenant between LTCM and its counterparties that would have obliged LTCM to disclose its overall gearing. UK banks have long been in the habit of demanding covenants from non-bank counterparties concerning their overall gearing, the Bank of England says.3.Was there moral hazard?The simple answer is yes, since the bailout of LTCM gave comfort that the Fed will come in and broker a solution, even if it doesn't commit funds. The Fed's intervention also arguably tempted Meriwether not to accept the offer from Buffett, AIG and Goldman. The offer, heavily conditional though it was, shows that the LTCM portfolio had a perceived market value. A price might have been reached in negotiations between Buffett and Meriwether. Meriwether's argument [and the Fed's] is that Buffett's deadline of 1230 didn't give Meriwether time to consult with LTCM's investors: he was legally unable to accept the offer.It is possible to argue that a market solution was found. Fourteen banks put up their own money, regarding it as a medium-term investment from which they expected to make a profit. From a value-preservation point of view it was an enlightened solution, even if it did seem to reward those whose recklessness had created the problem.Federal Reserve chairman Alan Greenspan defended the Fed's action at the October 1 hearing in the House Committee on Banking and Financial Services as follows: "This agreement [by the rescuing banks] was not a government bailout, in that Federal Reserve funds were neither provided nor ever even suggested. Agreements were not forced upon unwilling market participants. Credits and counterparties calculated that LTCM and, accordingly, their claims, would be worth more over time if the liquidation of LTCM's portfolio was orderly as opposed to being subject to a fire sale. And with markets currently volatile and investors skittish, putting a special premium on the timely resoluton of LTCM's problems seemed entirely appropriate as a matter of public policy."The true test of moral hazard is whether the Fed would be expected to intervene in the same way next time. Greenspan pointed to a unique set of circumstances which made an LTCM solution particularly pressing. It seems questionable whether the Fed would act as broker for another fund bailout unless there were also such wide systemic uncertainties.4. Was there truly a systemic risk?。
