(深度,重磅)吞噬一切的華爾街量化惡魔——復盤騎士資本以及LTCM(上)
The LTCM fiasco is full of lessons about:
2.意外的相關性或歷史相關性的細分
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.
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 havent 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.
3. Many counterparties had put on the same convergence trades, some of them as disciples of LTCM.
在這種情況下,金融槓桿本身是不被歡迎的。LTCM被迫清算以滿足追加保證金要求。1998年9月2日,Meriwether致函他的投資者,稱該基金當年損失了25億美元,佔其價值的52%,僅在8月就損失了21億美元。其資本基礎縮減至23億美元。Meriwether正在尋找一筆約15億美元的新投資來支持該基金。
根據雙邊Isda(國際互換與衍生產品協會)主協議,資產負債表外合約主要是凈額。他們中的大多數也是抵押。不幸的是,抵押品的價值自8月17日以來已經開始下跌。當然,長期資本管理公司(LTCM)擁有兩位原始衍生品和期權合約估價大師,其投資組合將通過壓力測試來應對近期的市場動蕩。但是,就像街上的許多其他風險價值(Var)建模者一樣,自8月17日以來市場中可怕的相關行為已經超出了他們最糟糕的情況。這種質量飛行沒有被預測到,可能 因為它顯然是非理性的。
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.
